Warranty

Step 1

Set it up

Place it on a level pad, fill it with a hose, and you're soaking the same week — no plumber, no hookups.

Step 2

Light the fire

Load the firebox, drop in a match, and the wood-fired stove brings the water up to soak temperature on its own.

Step 3

Make It a Ritual

The first few soaks tend to set the rhythm — the tub becomes a habit, not an expensive lawn ornament.

Frequently Asked Questions

How many people does the SaunaLife S6 fit?

The SaunaLife S6 seats up to seven people in a contoured dark grey fiberglass tub. SaunaLife lists the interior at 80.7 inches in diameter and 35.4 inches deep, inside an 89-inch-diameter Thermo-Spruce surround, and matching Thermo-Spruce steps make getting in and out easier. SaunaLife's safety instructions say not to exceed the recommended number of users, both for safety and to avoid damaging the tub, and to never jump in. For up to six people, the S4 is the smaller sibling.

What are the SaunaLife S6 dimensions?

SaunaLife lists the S6 at 89 inches in diameter and 40.2 inches high outside, and 80.7 inches across and 35.4 inches deep inside. Its dimension drawing puts the top of the stove's chimney about 106 inches above the base, so leave that much overhead clearance. The tub weighs 551 pounds empty; filled with 436 gallons it weighs roughly 4,190 pounds before anyone gets in, by arithmetic from those two figures. It ships in a crate 93 by 47.2 by 94.5 inches at 728 pounds, so check the delivery route for that size before it arrives.

How much water does the SaunaLife S6 hold?

The SaunaLife S6 holds 436 gallons. SaunaLife's quick guide says to close the drain valve before filling, shows the water level about 6 inches below the rim, and says the water should stand about 4 inches over the stove section. Never fire the stove until the tub is full, and never drain it while embers are still burning. Filled, the S6 weighs roughly 4,190 pounds before anyone gets in, from its 551-pound net weight plus the water, so the base has to carry that weight.

How long does the SaunaLife S6 take to heat up?

SaunaLife says the S6's stove heats its 436 gallons from 40°F to 95°F in 1.5 to 2 hours, which it puts at about a third of the time of traditional wood-fired hot tubs. The stove draws cooler water in through a lower channel and returns it through an upper one, and the air between the fiberglass tub and the wood surround is heated too. SaunaLife's quick guide says covering the tub with its lid speeds heating. It recommends a maximum water temperature of 105°F, and the stove must never be left unattended while it burns.

How does the SaunaLife S6's wood stove work, and what firewood does it need?

The SaunaLife S6's stove is a self-cleaning corrugated firebox of 304 stainless steel with a secondary chamber that takes heat from the smoke, and SaunaLife says it uses up to 50% less wood than other hot tubs. Burn only dry firewood no longer than 13 inches, and light it with a pellet fuel starter or lighter fluid rather than paper, which the quick guide says throws excess sparks and embers. Fire the stove only once the tub is full, keep watch while it burns, and remember that the stove and chimney get hot enough to burn. The polished stainless chimney and its cap are included.

Does the SaunaLife S6 need electricity, and can it be used off-grid?

No. The SaunaLife S6 needs no electrical connection, because its stainless-steel stove burns firewood, so it can go on a site with no power. What it does need is water to fill 436 gallons, somewhere to drain it, a supply of dry firewood no longer than 13 inches, and a spot at least 13 feet from any building, which SaunaLife's quick guide sets for fire safety. In freezing weather, the guide says to drain the tub and the stove after every use and leave the drain valve open, so plan for refilling in winter.

What wood is the SaunaLife S6 made of?

The SaunaLife S6 has a 1.65-inch Thermo-Spruce surround, thermally modified spruce that SaunaLife says lasts up to twice as long as cedar, around a thick, contoured dark grey fiberglass tub. The stove is 304 stainless steel with a polished stainless chimney, and the insulated cover is steel-reinforced foam with a dark grey marine-grade vinyl exterior. It comes in a Natural (S6N) or Black (S6B) finish.

How do you install the SaunaLife S6, and what foundation does it need?

The SaunaLife S6 arrives assembled apart from the chimney. Its quick guide has you remove the shipping boards and steps, turn the tub upright onto its base, cut away the pallet and plastic, and level it with a spirit level around the rim; then fit the chimney to the stove, set the grate, hang the stove door and connect the drain valve. The guide asks only for a level base, so size it for the filled weight, and the tub must stand at least 13 feet from any building for fire safety. Condensate can drip under the stove while it heats, so a container there is normal.

How is the SaunaLife S6 delivered and what does shipping cost?

The SaunaLife S6 ships by LTL freight for a flat $950 freight charge to the contiguous United States. Delivery is by appointment, and the driver makes a curbside delivery only, lowering the tub to ground level. It arrives assembled apart from the chimney, on its side on a wooden pallet encased in wood, in a crate 93 by 47.2 by 94.5 inches at 728 pounds, so plan how you will move it into place and turn it upright. Every Topture freight order includes full-value freight protection, and damage must be documented at delivery for a claim to be processed.

What does the SaunaLife S6 cost in total, delivered?

The delivered cost of the SaunaLife S6 from Topture is the tub price plus a flat $950 LTL freight charge to the contiguous United States. Some retailers advertise free shipping on the S6 at a higher tub price, so compare delivered totals rather than tub prices. The wood stove, chimney and cap, steps and insulated cover are included, so there is no heater or cover to add. The remaining costs are local: a level base that can carry the filled tub, and firewood. Topture quotes delivery outside the contiguous United States per order, and offers financing through Shop Pay Installments at checkout.

What warranty does the SaunaLife S6 have?

SaunaLife's Limited Warranty, Rev 260915, covers the SaunaLife S6 for 2 years from delivery, the period it lists for plunge tubs and hot tubs, in residential use. It runs to the original retail purchaser who bought from an authorized reseller, and Topture is an authorized SaunaLife dealer. SaunaLife repairs or replaces, at its option, a part it judges defective, and labour for removal or reinstallation is not covered. It excludes normal wear, user damage, natural weathering and the natural characteristics of wood, and defects, transport damage included, that inspection before installation would have caught. Commercial use, alteration or repairs by anyone other than an authorized SaunaLife representative void it.

Where can you buy the SaunaLife S6 from an authorized dealer?

Topture is an authorized SaunaLife dealer, listed in SaunaLife's own dealer directory, and sells the SaunaLife S6 in two finish options, Natural (S6N) or Black (S6B), as a complete package with its wood stove, stainless chimney and cap, steps and insulated cover. Buying from an authorized dealer matters because SaunaLife's limited warranty applies only to products bought from one of its authorized resellers. Topture provides Lifetime Expert Support, including troubleshooting and warranty coordination with SaunaLife.

How do you maintain the SaunaLife S6?

Wash the SaunaLife S6 after each use, and shower before getting in for cleaner water. SaunaLife's quick guide allows a pressure washer with household detergent and a soft cloth, but no chlorine-based detergents, abrasive cleaners or rough materials, which discolor the tub. Lift any ash that reaches the water out with a kitchen sieve. Treat the wooden walls and steps with an exterior wood oil at least once a year. In winter, drain the tub and the stove after every use and leave the drain valve open, because freezing water can break the tub, the stove or the valve.

What are common problems with the SaunaLife S6?

SaunaLife's quick guide for the S6 points to a few avoidable problems. Freezing is the costly one: water left in the tub, stove or drain valve in freezing weather can break them, so drain after every use in winter and leave the valve open. The guide forbids firing the stove before the tub is full, or draining it while embers are still burning. Condensate can drip under the stove while it heats, so a container there is normal. Paper used as kindling throws sparks and embers, ash in the water lifts out with a kitchen sieve, and chlorine or abrasive cleaners discolor the tub.

What is the difference between the SaunaLife S6 and the S4?

The difference is size. The SaunaLife S6 seats up to seven in an 80.7-inch interior holding 436 gallons, inside an 89-inch surround 40.2 inches high. The S4 seats up to six in a 71-inch interior holding 304 gallons, inside a surround SaunaLife lists at 79 inches across and 37 inches high. So the S6 needs a pad about 10 inches wider and holds roughly 1,100 pounds more water. Otherwise they are built the same way: a 1.65-inch Thermo-Spruce surround over a fiberglass tub and a 304 stainless-steel wood stove, with no electricity, and SaunaLife rates both to heat from 40°F to 95°F in 1.5 to 2 hours.

Every charge is shown at checkout before you pay.

Do you provide financing?

Absolutely! To view your financing offer, simply select Shop Pay Installments as your payment method at Step 3 of checkout.

You'll need to enter a debit card to receive your offer, but don’t worry—you can still back out before completing the purchase.

How long will it take for my items to arrive?

If your order is in stock, most orders ship within 2–7 business days of purchase. Transit time then depends on the distance from the warehouse and, for freight, on booking a delivery appointment.

For custom, pre-order or made-to-order items, the estimated delivery time frame is listed on the product page. Delivery dates are estimates, so please don't book installation labor until your order has arrived and been inspected.

What happens after I place my order?

As soon as you place your order, you'll receive a confirmation email with your order details—be sure to keep it for your records. Once your order ships, you'll receive another email with tracking information.

For freight deliveries, the carrier will call or text you to schedule an appointment once the shipment reaches their local terminal. Someone needs to be there to inspect the shipment and sign for it. Smaller parcels arrive by UPS or FedEx without an appointment.
