Sun Home vs Redwood Outdoors Sauna: Specs, Warranty and Returns Compared

By Evan Reid, with research from the HPG Research Team · Updated Oct. 4, 2026

Chores done, you grab a towel from the hook and head for the sauna at the back of the yard. Sun Home vs Redwood Outdoors is first a choice of heat. Redwood's FAQ says it carries only traditional Finnish saunas, and most of Sun Home's lineup is infrared. Compare prices after that.

For infrared outdoors, start with the Sun Home Luminar 2: the Luminar is the only outdoor infrared sauna in either lineup, and this size runs on one 240V, 20 A GFCI circuit. As of October 5, 2026, the regular price is $11,599, and a sale was running. For traditional heat indoors at the lowest price for three, Redwood's Haven is $5,499 as of the same date, heater included.

One line to settle first: Sun Home's blog says the Luminar 2 "ships fully assembled," but its product page says it "arrives palletized at the curb." Plan on half a day of assembly with two people.

Between September 26 and October 5, 2026, we read both makers' spec sheets, manuals, FAQs, policy pages and prices.

Sun Home vs Redwood Outdoors: which models actually compare?

One pair matches closely: Sun Home's Nova 3 and Redwood's Haven, both 3-person indoor traditional saunas with 6 kW heaters on 30 A circuits. Most other matchups set two different kinds of sauna side by side, and the Nova 6 against the Retreat pairs two traditional saunas of different sizes, six seats against four.

Both brands include a heater in the listed price, and Redwood's standard heater is a manual 6 kW Harvia KIP on most models, with upgrades at extra cost. Sun Home lists sizes as width by depth by height, and Redwood as length by width by height.

Find the matchup that fits your room in the first column, then check its power column against the circuit you can add.

Sun Home labels its figure "assembled weight," while Redwood's specifications list a plain "Weight" without saying whether that is the built sauna or the crate. Ask Redwood which before you plan the pad or the move.

Redwood has no traditional sauna in Sun Home's Solaris price range. Its most expensive model, the 8 to 10 person Grove, is $11,699 as of September 29, 2026, less than a third of the Solaris 4.

What this means for you: on the one close pair, the Nova 3 costs $7,000 more than the Haven as of September 29, 2026, and buys 7 years on cabinetry against 1. If that coverage is worth the difference to you, the Nova 3 is your traditional pick. If the price matters more, it's the Haven. The other gaps, $5,700 (Luminar 2 against Duo) and $7,200 (Luminar 5 against Cabin) as of the same date, sit between two kinds of heat, so settle the heat first.

Infrared or traditional: which Sun Home or Redwood sauna to get

Choose the heat first, because it decides which brands are in play. Infrared means Sun Home, since Redwood sells none, and as of September 29, 2026, every Redwood sauna cost less than Sun Home's least expensive traditional model, the $12,499 Nova 3. If you want infrared in the yard but aren't set on Sun Home, our best outdoor infrared sauna picks put both Luminars beside other cabins, including two that run on 120V.

Sun Home's indoor infrared cabins are the Solstice (far infrared, 1 to 4 people, $5,599 to $8,599 as of September 29, 2026), the Equinox, the Eclipse and the 1-person Pod. Its outdoor infrared sauna is the Luminar, with a cedar interior and an aluminum exterior, in 2-person and 5-person sizes. Its traditional saunas are the indoor Nova, with HUUM Drop heaters, and the outdoor Solaris, built to order in Europe with an estimated 3 to 4 month lead time.

Redwood's saunas collection held 17 models on September 26, 2026, every one traditional, from $4,299 to $11,699. The 8-person Garden, Noctra and Barrel come with an 8 kW KIP, and the Grove comes with a 9 kW Homecraft Revive.

The heat and the waiting differ as much as the price. Sun Home's Luminar manual gives a 90 to 170°F setting range and 15 to 20 minutes to warm up at 65 to 80°F outside, or 60-plus minutes below 40°F. The Solstice 2 spec sheet lists 130 to 140°F, and Sun Home rates the Nova and Solaris up to about 230°F.

Redwood's Haven manual describes traditional sessions at 160°F to 185°F after a preheat that "typically takes 45 minutes to an hour," and Redwood's FAQ says its UL-listed heaters "run for a maximum of 60 minutes at a time" before you restart them. So on a winter evening, plan on about an hour between switching on a Luminar or a Haven and stepping in.

Controls differ too. The Luminar runs on Sun Home's app over 2.4 GHz Wi-Fi, and the Nova and Solaris use the HUUM app. Redwood's standard KIP has dials and a delay timer. Wi-Fi is an upgrade you choose at purchase, because Redwood says "It is not possible to upgrade manual control Harvia heaters to Wi-Fi control."

Checkpoint: the heat source. If you want infrared, your shortlist is Sun Home's Solstice 2 indoors on 120V, or the Luminar 2 or Luminar 5 outdoors. If you want a traditional heater and stones, it's Redwood's lineup plus Sun Home's indoor Nova and its made-to-order Solaris. Settle this first.

By late October the yard is dark before dinner, and the porch light is on. The Luminar stands on the pad you poured, its aluminum exterior beside the fence and its cord running to the twist-lock outlet your electrician set within 6 feet of the cord exit. You step into the cedar and close the door behind you.

Sun Home Luminar 2: infrared outdoors for two

The Luminar 2 is our pick for infrared outdoors: cedar inside, aluminum outside and room for two. It plugs into one dedicated 240V, 20 A GFCI circuit through a NEMA L6-20 twist-lock, where the Luminar 5 needs 30 A. Cabinetry and heaters are covered for up to 7 years. Its regular price is $11,599 (October 5, 2026).

• Best for: two people outdoors, with room for that circuit and an outlet within 6 feet of the cord exit.
• Skip it if: you can't give it a draining pad that supports at least 1,500 lb.
• Main compromise: labor and shipping coverage ends at 90 days, and the exterior cabin gets 3 years.

Confirm before you order: Sun Home's blog says it "ships fully assembled at 970 lbs," but the product page says it "arrives palletized at the curb." Plan on the product page's half day with two people, and ask Sun Home how yours ships (question 3 in the list below). The rest of the Luminar questions, including the 5-foot line and the unattended-use warning, are on the same list.

See the Luminar 2 at Sun Home

Sun Home Luminar 5: infrared outdoors for up to five

Get the Luminar 5 if you want the same cedar and aluminum cabin, with room for five. It runs on a dedicated 240V, 30 A GFCI circuit with a NEMA L6-30 twist-lock, at $14,499 as of September 29, 2026.

• Best for: four or five people outdoors, on a 240V, 30 A circuit you can add.
• Skip it if: the spot can't take an 82.25 by 51.75 inch footprint plus 8 inches behind and beside.
• Main compromise: labor and shipping coverage ends at 90 days, and the pad and overhead figures need Sun Home's confirmation.

Its spec sheet asks for a pad supporting "at least 1,270 lb," the same figure as its crate's gross weight, and 12 inches above the roof. The smaller Luminar 2 asks for 1,500 lb and 20 to 24 inches. Size the pad for the sauna plus everyone in it, and get Sun Home's confirmation before you pour (questions 1 and 2 in the list below).

See the Luminar 5 at Sun Home

Sun Home Solstice 2: infrared indoors on a 120V circuit

If the sauna is going indoors and a 240V circuit is a stretch, the Solstice 2 is our 120V pick, on a dedicated 120V, 20 A circuit with a NEMA 5-20 plug. Check its 50.9 by 45.9 inch footprint against your room. Sun Home sells it with a "7-Year Warranty." As of October 5, 2026, the regular price is $6,199.

• Best for: two people indoors, on a dedicated 120V, 20 A circuit with a GFCI or dual-function breaker.
• Skip it if: the sauna has to stand outside; Sun Home's outdoor infrared cabin is the Luminar.
• Main compromise: far infrared only, listed at 130 to 140°F.

Sun Home's warranty page also footnotes a prorated 3-year term for the Solstice and Equinox that no line above it refers to, so ask whether it applies to your order (question 7 below). With that answer, the Solstice 2 is ready to order.

See the Solstice 2 at Sun Home

Sun Home Nova 3: traditional heat with the longer cabinetry warranty

Choose the Nova 3 if you want traditional heat indoors with a longer cabinetry warranty than Redwood's: Sun Home defines its "limited lifetime" cabinetry term as 7 years. The heater is under HUUM's own warranty, 3 years on the body and controls, with elements not covered. That's room for three, with a 6 kW HUUM Drop heater hardwired on a dedicated 240V, 30 A circuit. As of October 5, 2026, the regular price is $12,499.

• Best for: three people indoors who want traditional heat and the HUUM app.
• Skip it if: the sauna has to go outdoors, since the Nova is indoor only.
• Main compromise: $7,000 more than the Haven as of October 5, 2026, and replacement parts only: "Labor and technician costs are not covered."

Confirm before you order: the Nova warranty is void if the sauna "is not plugged directly into the required dedicated electrical wall outlet," yet the manual says it "is hardwired." Ask Sun Home how that clause applies, and ask for the manufacture date, which the Nova terms tie coverage to (questions 4 and 5 in the list below). The unattended-use question below applies to the Nova too.

See the Nova 3 at Sun Home

Redwood Outdoors Haven: traditional heat indoors for three, for the least money

For a 3-person traditional sauna indoors, the Haven is the one to get: $5,499 as of October 5, 2026, with a 6 kW Harvia KIP included. It seats three, with a heater and stones you pour water over. Its product page said "Free Shipping Included" when we checked.

• Best for: three people indoors, in a spot that takes its 54¼ by 63 inch footprint.
• Skip it if: you want more than 1 year of coverage on the sauna.
• Main compromise: two runs for your electrician, a hardwired 240V heater circuit and a 120V light line with a switch.

If the room takes 72½ inches across instead of 63, Redwood's 4-seat Retreat lists the same $5,499 in the table (September 29, 2026). Its page said shipping is calculated at checkout, though, so compare the two delivered prices.

Redwood's own documents disagree on the heater's warranty. The product pages give Harvia heaters 1 year on elements and 5 on other parts, while the Haven manual says "Our saunas and sauna heaters come with a 1-year limited warranty." Plan on 1 year until Redwood settles it.

Redwood also lists the Haven at 800 lb, the same as the 2-seat Alcove and the 4-seat Retreat, so ask whether that is the built sauna or the crate.

Want traditional heat in the yard instead? Redwood's outdoor models in the table are the 2-seat Duo at $5,899 and the 4-seat Cabin at $7,299, as of September 29, 2026, and both pages said shipping is calculated at checkout.

To order the Haven, get Redwood's delivered price to your zip code in writing, then order from Redwood's own store.

Sun Home sauna electrical requirements vs Redwood Outdoors: can your house power it?

Every outdoor sauna from either brand needs a 240V circuit, and how that circuit is protected and connected is where the brands differ most on paper.

Sun Home. The Luminar 2 spec sheet calls for a "Dedicated 240V / 20A circuit with GFCI protection," a NEMA L6-20 twist-lock plug and receptacle, and an outlet within 6 feet of where the 8-foot cord leaves the roof at the back wall. The Luminar 5 is the same arrangement at 30 A with an L6-30.

The Solstice 2 runs on a dedicated 120V, 20 A circuit with a NEMA 5-20 plug, and Sun Home now tells buyers to "Include a GFCI or dual-function (AFCI/GFCI) breaker; check local code." Our home sauna electrical requirements guide covers why heater manuals and breaker sizes disagree.

If a 240V run is off the table and the sauna can go indoors, the Solstice 2 is the one sauna in the matchup table that runs on 120V.

See the Solstice 2 at Sun Home

The Nova is hardwired on a dedicated 240V circuit, 30 A for the Nova 3 and 40 A for the Nova 6, and its spec sheets and owner's manual don't mention GFCI. Its assembly guide does. It says HUUM's heater and controller manuals recommend connecting the heater "without a GFCI breaker," because heating elements of this type can trip one during normal operation.

Where local code requires ground-fault protection, the guide leaves the choice of device to the electrician. The Solaris 4 is hardwired on 240V, 30 A.

Redwood Outdoors. Every Redwood sauna lists "120V for lighting and 240V for heater." The heater is hardwired by a licensed electrician, and the breaker follows the heater you pick. Redwood's electrical FAQ lists a two-pole 30 A breaker for a manual 6 kW heater ("10/2 wire (use 8/2 if distance >90 ft)"). It lists 40 A for 8 kW, and 50 A for the 9 kW Homecraft and a 10.5 kW Harvia Wi-Fi heater.

It also specifies a "Standard (non-GFCI) 2-pole breaker." With a non-Wi-Fi heater, the light needs "a separate 120V power line, and a switch must be wired in-line." A Harvia Wi-Fi heater can feed the light from its power unit instead, but the electrician has to bring a neutral to that unit.

So Sun Home requires GFCI protection on its 240V outdoor Luminar, while Redwood specifies a non-GFCI breaker for its heaters, the same direction Sun Home's Nova assembly guide takes for its HUUM heater. The Luminar and a Redwood sauna are different products, a plug-in infrared cabin against a hardwired stove heater, so each instruction applies only to its own product.

What this means for you: on a Redwood, choose the heater before the electrician quotes. Moving from the included 6 kW to an 8 kW takes you from a 30 A to a 40 A breaker. For heater sizing by room volume, see what size sauna heater you need.

When you call the electrician, bring these:

• The model's spec sheet or Specifications tab, with its volts, amps and GFCI line, and on a Redwood, the heater you chose.
• Plug or hardwire: an L6-20 or L6-30 twist-lock for a Luminar, a NEMA 5-20 plug for a Solstice 2, hardwired for a Nova, Solaris or Redwood heater.
• The distance from your panel to the spot.

Weight, pad and clearances: will your site carry it?

Plan the pad for the sauna plus everyone in it, since neither brand's weight figure includes the people inside.

Sun Home publishes a site spec for each Luminar. The Luminar 2 needs a draining pad that extends at least 6 inches past the footprint and supports "at least 1,500 lb." It wants 4 to 6 inches behind and beside the sauna and 20 to 24 inches above the roof.

The Luminar 5 needs a pad supporting "at least 1,270 lb," at least 8 inches behind and beside, and 12 inches above. The Luminar manual also says the roof is "not designed to withstand more than 1 foot of snow." If your winters bring more than a foot of snow, plan to clear the roof.

The Nova needs at least 12 inches on the right for the air intake, 24 inches on the left beside sheetrock and 24 inches above for electrical work, and it is indoor only.

Redwood's outdoor saunas list 900 lb (the 6-person Barrel and Vista) to 1,543 lb (Grove). Its foundations FAQ asks for a concrete pad at least 4 inches thick and reinforced with mesh, a deck built to carry "over 1,000 lbs," and concrete pavers under the cradles if the sauna sits on the ground.

Redwood's outdoor product pages give no clearance number, only "sufficient clearance for assembly and access." Its Haven indoor manual asks for at least 4 inches on sides with vents and 2 to 4 inches elsewhere. On an outdoor Redwood, ask Redwood for a clearance figure before you size the pad.

Tape out the footprint plus those clearances where the sauna will stand. Our outdoor sauna guide compares pad and footprint numbers across more makers, and for a garage, see whether a sauna can go in a garage.

Redwood Outdoors warranty vs Sun Home sauna warranty: what's actually covered?

On paper, Sun Home's is longer: up to 7 years on most cabinetry, against 1 year from delivery on a Redwood.

Find the part you care about in the first column, then compare the two terms across, and read the labor row before you count years.

Coverage	Sun Home	Redwood Outdoors
Sauna cabin	Luminar: "limited lifetime" on cabinetry and heaters, up to 7 years, and 3 years on the exterior cabin. Solstice and Equinox: 7 years. Nova: "limited lifetime" on cabinetry, defined as 7 years. Solaris: 3 years on cabinetry	1 year from delivery
Heater	Luminar and Solstice heaters sit inside the cabinetry term. Nova: HUUM's own warranty, 3 years on the heater body and controls, elements not covered. Solaris: Sun Home refers you to HUUM's warranty	Harvia, under a warranty Redwood administers: 1 year on heating elements, 5 years on other components. Homecraft: 2 years on elements, 1 year on other components
Controls	Luminar and Solstice: 3 years. Nova fan and light controls: 1 year	Under the heater terms
Labor and shipping	Luminar: first 90 days only. Nova: replacement parts only, "Labor and technician costs are not covered"	Labor and electrician costs not covered unless Redwood approves in writing. Redwood pays reasonable shipping when it asks for a defective part back
Who is covered	Original purchaser only	Original purchaser only
Cold plunge	1 year (Cold Plunge Pro)	1 year

Both warranties exclude weather damage and improper installation, including electrical work. Sun Home's general warranty terms, which name the Eclipse, Pod, Luminar and its traditional saunas, add conditions of their own.

Delivery has to happen "within six (6) months of purchase" for the term to run from delivery. And the sauna must sit at least five feet from "any source of water that produces liquid or vapor, such as a cold plunge, shower, bathtub, hot tub," or the warranty is automatically void. Sun Home's Nova terms also say the sauna "must be purchased and used within one year of its manufacture date."

Redwood's sauna warranty excludes "improper electrical work, site preparation, or contractor error" and does not pay for an electrician, crane or permit.

What this means for you: on a Sun Home, take delivery inside six months and keep the sauna at least five feet from any water source, such as a plunge, shower, bathtub or hot tub. On a Redwood, the site work is yours to pay for.

Use the makers' own pages when you compare. A best outdoor saunas list that ranks for these brands, updated September 23, still gives the Luminar "Heaters: 6 years; other components: 1 year," a split in neither Sun Home's current terms nor its terms for orders before March 2, 2026.

Shipping, delivery and assembly: how does it get to your backyard?

From the curb, the move is yours with either brand, so line up the people or the equipment before the carrier calls.

Sun Home includes curbside freight with a liftgate and a delivery appointment. Its FAQ puts saunas and the Cold Plunge Pro at about 2 to 4 weeks door to door and says in-stock items leave within 7 business days. Its shipping policy also says "many of our sauna models are on backorder" and asks buyers to email before purchasing.

If you can't move the boxes yourself, ask Sun Home to quote its "Room of Choice" upgrade when you order. It moves the boxes to a garage, patio or room, priced on request, and assembly is still yours.

The Luminar arrives on a pallet and Sun Home says to "set aside a half day" with at least two people. The Nova ships as one crate (807 lb gross for the Nova 3) with the heater and controls in a separate shipment. The Solaris arrives pre-assembled.

For concealed damage, Sun Home says to open every box within 5 business days of delivery, so schedule the unpacking for that week.

Redwood Outdoors ships each sauna in a wooden crate by freight, usually on a truck with a liftgate, and the carrier calls to set an appointment after the crate reaches the local depot. Delivery is curbside only, and Redwood says carriers "cannot move it to your backyard, garage, or inside your home." The heater may ship separately and needs a signature.

Shipping cost depends on the model page you land on: the Haven, Cove and Extra-Wide Barrel pages said "Free Shipping Included," while the Duo, Cabin, Alcove, Retreat and most others said "Shipping calculated at checkout."

Assembly is a DIY kit Redwood describes as "just a few hours using basic construction skills," with a power drill and Torx bit, a rubber mallet and a level on the tool list. Damage has to be marked on the bill of lading and emailed within 7 days, so look the crate over while the carrier is there.

---

Returns, cancellations and financing: what if you change your mind?

Redwood lets you cancel free for seven days, while Sun Home charges 3% at any stage. Returns are narrow at both, so be sure before you order.

Sun Home charges its 3% cancellation fee on every canceled product. On a Luminar 2 at its $11,599 regular price as of October 5, 2026, that is $347.97, by our arithmetic. You can cancel an in-stock order within 24 hours of placing it.

After that the order is in fulfillment, a 25% restocking fee applies, and round-trip freight may be added depending on where the shipment is. Returns are accepted within 30 days of delivery only for unused saunas "in their original, unopened packaging," again with a 25% restocking fee plus outbound and inbound shipping, "even if your order was placed during a free shipping promotion."

On the same Luminar 2 price as of October 5, 2026, the restocking fee is $2,899.75 before freight, by our arithmetic. Sun Home will not take back an uncrated, assembled or used sauna, and made-to-order traditional saunas such as the Solaris are non-refundable.

So the real decision happens before you pay. Mark out the Luminar 2's 57 by 51.5 inch footprint with its clearances, and get the electrician's quote for the 240V, 20 A GFCI circuit. With both in hand, you're ordering a sauna you already know fits.

Redwood refunds a cancellation in full within seven days of ordering. After that it charges 3.5% of the order, which is $206.47 on a $5,899 Duo at its September 29, 2026 price, by our arithmetic. Returns within 30 days of delivery need prior written approval, and Redwood "may accept" them "subject to satisfaction of certain conditions to be determined solely by Redwood Outdoors."

Any refund comes back "less any charges for shipping and handling and other applicable costs." Redwood publishes no restocking percentage. If you cancel or return one half of a sauna and plunge bundle, the bundle discount comes off your refund.

Both brands finance through Affirm and take HSA or FSA funds through TrueMed. Redwood's product pages stated "Rates from 0–36% APR" when we checked, with an example of $271 a month over 24 months at 0% APR on a $6,500 purchase.

Sun Home's pages show Affirm's monthly estimate and link to Affirm's disclosures but print no APR range. Sun Home's FAQ says to sign out of Shop Pay, or use another device, to reach the Affirm option at checkout.

Redwood Outdoors cold plunge vs Sun Home cold plunge: which fits your plan?

Both brands sell cold plunges with a built-in chiller, and Redwood's two all-in-one models also heat the water.

Start with the electrical and filled-weight rows, which decide where each plunge can sit, then compare price and water.

	Sun Home Cold Plunge Pro	Redwood Alaskan All-In-One	Redwood Denali All-In-One
Price, Sept 29, 2026	$14,599	$6,999 Standard, $7,999 Wi-Fi	$7,999 Standard, $8,999 Wi-Fi
Outside size	78.7 L x 33.5 W x 34.2 H in.	57 L x 37 W x 44 H in.	70 L x 33 W x 37 H in.
Water	150 gallons	104 gallons	80 gallons
Dry weight	400 lb	360 lb	300 lb
Filled weight, our arithmetic	about 1,651 lb	about 1,227 lb	about 967 lb
Water temperature	28 to 70°F set point	37°F to 104°F	37°F to 104°F
Electrical	120V, 12 A, NEMA 5-15 plug, dedicated 15 A GFCI circuit	120V, 12 A max, household outlet, GFCI plug adaptor included	Same as Alaskan
Sanitation	Ozone and UV	UV	UV
Space around it	3 ft at the vent end, 1 ft each side	3 ft of open space beside the vents	Same as Alaskan
Warranty	1 year	1 year	1 year

Filled weights use 8.34 lb per gallon and leave out the person. Redwood allows an extension cord "rated for 15A or more and made specifically for outdoor use." Sun Home's Pro spec calls for a dedicated 15 A GFCI circuit instead.

Redwood says its plunges must be drained and winterized below 32°F ambient, and that damage from use below 32°F is not covered. If your winters drop below freezing and the plunge stays outside, plan to drain and winterize it for those months. For circuits and floor loading, see our guides to cold plunge electrical requirements and cold plunge floor load.

If you want a sauna and a plunge together, plan the spacing before you order. Sun Home's warranty is void if the sauna sits closer than five feet to a cold plunge. Redwood sells 14 sauna and plunge bundles, and we found no distance rule anywhere on its site.

Get the Cold Plunge Pro if you want the coldest set point here, down to 28°F, with ozone and UV, on a dedicated 15 A GFCI circuit. At $14,599 as of September 29, 2026, it costs $7,600 more than Redwood's Alaskan Standard, by our arithmetic, and holds 150 gallons to the Alaskan's 104. For one tub that cools and heats, from 37°F to 104°F on a household outlet, Redwood's Alaskan or Denali does both.

What to confirm with Sun Home before you order

Seven of Sun Home's own statements point two ways, some within the same document. Each becomes a question to send before you pay, and the list at the end is ready to paste.

The smaller Luminar needs the stronger pad. The 970 lb Luminar 2 calls for a pad supporting at least 1,500 lb. The 1,070 lb, five-seat Luminar 5 calls for at least 1,270 lb, which is the same figure as its crate's gross weight and leaves 200 lb for five people. Overhead clearance runs backward too: the Luminar 2 wants 20 to 24 inches above the roof, and the larger Luminar 5 wants 12.

Both spec sheets are the current versions, dated September 14, 2026, and the owner's manual, dated September 25, 2026, repeats both clearance figures. Size your pad for the sauna plus everyone in it, and ask Sun Home to confirm the Luminar 5 figure.

Assembled or not. A Sun Home blog comparison, with specifications it lists as checked July 29, 2026, says the Luminar 2 "ships fully assembled at 970 lbs." The Luminar product page says it "arrives palletized at the curb," that the panels "assemble with two or more people," and to set aside half a day. The Luminar 2 also has its own assembly guide, so plan on assembly.

A plug rule for a sauna with no plug. The Nova warranty is void if the sauna "is not plugged directly into the required dedicated electrical wall outlet (using a power strip, extension cord, or converter is prohibited)." The Nova manual says it "is hardwired, not plugged into a household outlet." Ask Sun Home in writing how that clause applies to a hardwired Nova.

Unattended use. The Luminar manual says "Never leave the sauna plugged in and switched on unattended" and to unplug it when not in use. Later in the same manual, a tip suggests using the app's Schedule feature "to have your sauna warm and ready before you get home." The Nova manual pairs "Never leave the sauna heating and unattended" with a tip to start heating remotely. Follow the never-unattended line until Sun Home says which governs.

"Limited lifetime" and "7-Year" are the same length. The Luminar and Nova carry a "Limited Lifetime Warranty" badge, and the warranty page defines that lifetime as up to seven years. The Solstice page calls the same seven years a "7-Year Warranty." The Luminar's exterior cabin gets 3 years.

The Solstice and Equinox section of the warranty page also ends with a footnote describing a prorated 3-year term (100%, then 60%, then 30%) that no line above it refers to.

Stock messages. Sun Home's product pages all showed "Low in stock right now," including the made-to-order Solaris with its 3 to 4 month lead time. The shipping policy says many sauna models are on backorder. Get a ship date in writing.

Indoor or outdoor. The Luminar product page and spec sheets describe an outdoor sauna. The owner's manual says both Luminar sizes "are designed for indoor or outdoor use." If you want a Luminar indoors or in a garage, plan on outdoor use only until Sun Home confirms an indoor install in writing.

The product page also says the dedicated circuits are "installed by a licensed electrician, at least 5 feet from other electrical devices," a line that appears in none of the spec sheets, the manual or the assembly guides. The spec sheets instead put the outlet within 6 feet of the cord exit, so ask Sun Home what the 5-foot line means for your layout.

Before you order, email Sun Home these questions:

1. Is the Luminar 5's pad figure of at least 1,270 lb correct?
2. Does the Luminar 5 need 12 inches above the roof, when the smaller Luminar 2 asks for 20 to 24?
3. Does the Luminar 2 ship fully assembled, or palletized for assembly?
4. How does the Nova warranty's plug clause apply to a hardwired Nova?
5. What is the manufacture date of the Nova on this order?
6. May the sauna be started remotely, given the manuals' unattended-use warning?
7. Does the prorated 3-year footnote apply to a Solstice or Equinox ordered now?
8. Is an indoor install of the Luminar supported, as the owner's manual says?
9. What does the product page's 5-foot line mean for an outlet within 6 feet of the cord exit?
10. What is the ship date for this order?

With those answers saved, the Luminar, Solstice or Nova you picked is ready to order.

What to confirm with Redwood Outdoors before you order

Five of Redwood's own statements don't line up, some on the same page, starting with which warranty covers your heater.

Three heater warranties. Redwood's product pages say Harvia heaters get 1 year on elements and 5 years on other parts, and Homecraft heaters get "a 2-year limited warranty." Redwood's formal Homecraft warranty covers elements for 2 years but "All other components" for only 1 year. And Redwood's current manuals, including the Haven manual (version 3.0, dated August 27, 2026), say "Our saunas and sauna heaters come with a 1-year limited warranty."

Harvia's own warranty terms, dated November 18, 2025, give Harvia heaters a different term again: 2 years in family use, heating elements included. Harvia adds 1 more year if you register the heater with Harvia within 30 days of purchase. Redwood's Harvia heater warranty says Redwood administers it, so ask Redwood in writing which terms cover your heater, and save a copy of each warranty page with your order.

How to send it back. Redwood's Shipping & Returns policy says "Products must be returned in their original wood crates." Its Shipping Methods page says returns "must be disassembled, placed on a pallet, and shipped back." Keep the crate until you're sure the sauna stays, and ask Redwood which method applies to you.

Free shipping or not. Some Redwood product pages say "Free Shipping Included," most say shipping is calculated at checkout, and the shipping FAQ says "Shipping cost depends primarily on your location" and to call for a quote. Get the delivered price for your zip code before you pay.

Weights. The foundations FAQ says "Our lightest sauna weighs ~900 lbs." The Alcove, Haven and Retreat indoor saunas are each listed at 800 lb, even though the Alcove seats two and the Retreat seats four. The same FAQ says the heaviest sauna is about 2,000 lb, and the heaviest current listing is the Grove at 1,543 lb. Plan the move for at least the FAQ's 900 lb until Redwood says what the 800 lb listings measure.

Assembly on the plunge. The Alaskan All-In-One page says "Minimal assembly required" in one section and "no assembly required" in another. Plan for some assembly.

Send Redwood Outdoors these questions before you order:

1. Which warranty covers the heater on this order: the product page's Harvia terms, the manual's 1-year line, or Harvia's own terms?
2. If this sauna goes back, does it ship in its original wood crate, or disassembled on a pallet?
3. What is the delivered price of this model to the zip code on this order?
4. Is this model's listed weight the built sauna or the crate?
5. What clearance does this outdoor model need on each side and above?

Once Redwood answers in writing, order the Haven, or the Redwood that fits your yard, from Redwood's own store.

What if neither brand fits your room?

Sun Home sells fixed sizes, and Redwood Outdoors sells traditional saunas only. If you want infrared and no standard size fits, a sauna designed around the room is the third route.

SaunaCloud orders can't be canceled once placed, so its 3D renderings and proposal are where you decide. Check the layout against your room before you order.

Before you order

1. Decide on infrared or traditional first. For infrared, it's Sun Home: the Luminar 2 or Luminar 5 outdoors, the Solstice 2 indoors on 120V. For traditional heat indoors for three, the Haven costs least and the Nova 3 carries the longer cabinetry warranty: see the Nova 3 at Sun Home.
2. Send the exact model's spec sheet or Specifications tab to your electrician, with the list from the electrical section. A Luminar needs a GFCI-protected 240V circuit with an L6 twist-lock receptacle within 6 feet of the cord exit. A Redwood sauna needs a hardwired 240V heater circuit sized to the heater you choose, plus a 120V light line and switch unless you buy a Harvia Wi-Fi heater.
3. On Redwood, choose the heater at purchase. The included 6 kW KIP is manual, and Redwood says a manual Harvia heater can't be upgraded to Wi-Fi later.
4. Size the pad for the sauna plus the people in it, and measure overhead. Use Sun Home's 1,500 lb figure for the Luminar 2, ask Sun Home to confirm the Luminar 5's 1,270 lb, and follow Redwood's 4-inch reinforced pad or deck guidance. The Luminar 2 wants 20 to 24 inches above the roof, and the Nova wants 24 inches above the cabin.
5. If a cold plunge, shower or hot tub is part of the plan, keep a Sun Home sauna at least five feet away from it.
6. Get the delivered price and a ship date in writing. Ask Redwood whether shipping is free for your model and zip code. Sun Home's policy mentions backorders, and the Solaris takes 3 to 4 months.
7. Plan the move from the curb. The Sun Home saunas in the table above run from 522 to 1,697.56 lb, and Redwood lists its saunas at 800 to 1,543 lb.
8. Do the return math before you buy: 3% to cancel and 25% plus freight both ways to return at Sun Home, and 3.5% after seven days at Redwood with returns at its discretion.
9. Check permit rules before the crate arrives. Redwood's pages say a building permit or HOA approval "may be required." Our sauna permit guide covers the common cases.
10. Send each maker its questions from the confirm sections, and keep the answers with your order. Then order the sauna your numbers point to; for infrared outdoors, see the Luminar 2 at Sun Home.

Common questions

Does Redwood Outdoors sell infrared saunas? No. Redwood's FAQ says it carries only traditional Finnish saunas, and every sauna in its catalog on September 26, 2026 came with an electric stove heater. Sun Home sells both infrared models (Solstice, Equinox, Eclipse, Pod and Luminar) and traditional models (Nova and Solaris).

Which has the better warranty, Sun Home or Redwood Outdoors? On paper, Sun Home. Its Luminar and Nova cabinetry carry a "limited lifetime" term that Sun Home defines as up to seven years, while a Redwood sauna is covered for one year from delivery. Sun Home's Luminar labor and shipping coverage ends after 90 days, and Nova coverage is replacement parts only.

Do Redwood Outdoors saunas come with a heater? Yes. Most include a manual 6 kW Harvia KIP, the 8-person Garden, Noctra and Barrel include an 8 kW KIP, and the Grove includes a 9 kW Homecraft Revive. A licensed electrician has to hardwire the heater, and the light needs its own 120V line unless you choose a Harvia Wi-Fi heater.

What are the Sun Home sauna electrical requirements compared with Redwood? The outdoor Luminar plugs into a dedicated 240V circuit with GFCI protection, 20 A for the 2-person and 30 A for the 5-person, through a twist-lock plug. Redwood heaters are hardwired on 240V with a breaker sized to the heater, 30 A for the included 6 kW, and Redwood specifies a standard non-GFCI breaker.

Can you return a Sun Home or Redwood Outdoors sauna? Only in narrow cases. Sun Home takes back unused saunas in unopened packaging within 30 days, minus a 25% restocking fee and freight both ways, and refuses assembled or made-to-order units. Redwood may accept a return within 30 days with prior written approval, at its own discretion, and deducts shipping, handling and other costs.
