List prices of 44 sauna kits at topture.com (United States, USD), seen on 2026-10-17. One retailer's listed prices, before delivery, tax and installation; heaters are included in some kits and sold separately with others.
Barrel saunas are the cheapest way into a full-size outdoor sauna. At one large US retailer in October 2026, 11 barrel kits listed from $4,790 to $8,189, with a median of $5,990. Small cube saunas start in the same range, but outdoor cabins climb fast with size, glass and design: the cabins in the same listing ran from $4,890 to more than $75,000. Indoor kits, pre-cut rooms you assemble in a basement or a bathroom, listed from $4,098 to $23,604.
These are list prices before delivery, sales tax, a foundation and the electrician. Some kits include the heater, others leave it to you, so compare like with like. In Europe, barrel and cabin saunas from Baltic and Polish makers sell widely; we have not collected their prices yet.

List prices at topture.com (USD), seen on 2026-10-17, for the heaters and stoves in our catalog that the shop lists. One shop's prices; controls, stones and installation come on top for many models.
The heater is one of the largest items in any build. At a European dealer in October 2026, 25 electric heaters of 4.6 to 8 kW, the size most home saunas need, listed from €343 to €3,822, with a median of €549. At a US retailer, 11 heaters of that size listed from $1,092 to $3,648, with a median of $1,777. Design, a separate control unit and Wi-Fi control push the price up. Wood-burning stoves span the widest range: from about €500 for a plain stove to several thousand, and far more for large heat-storing stoves built for big rooms.
The right size matters more than the brand: an oversized heater costs more and cycles on and off, an undersized one never gets the room hot. The heater size calculator gives the output for your room, and the heater catalog lists the models rated for it.
What a DIY build needs
Building the room yourself replaces the kit price with materials. For a small indoor sauna of 2.0 × 1.8 m with a 2.1 m ceiling, the build cost calculator counts about 20 m² of tongue-and-groove panelling (some 220 m of 90 mm boards), 18 m² of insulation, 21 m² of aluminium foil, around 74 m of framing timber and 25 m of bench boards, plus the door, the heater, stones, vents, a light and the electrician. Enter your shop's prices there and it adds them up.
The wood is the biggest variable after the heater: cedar costs several times more than spruce or aspen (which wood for a sauna). A glass door costs more than a wooden one but makes a small room feel larger. The insulation and the foil are cheap, and the vapour barrier is not the place to save.
What it costs to run
An electric heater runs at full power while the room heats up, then switches on and off to hold the temperature, so the cost per session depends on the heater, the room, the insulation, the weather and your electricity price. The sauna running cost calculator works it out with your tariff and climate; outdoor saunas in a cold winter cost noticeably more per session than indoor ones.
Costs people forget
- Delivery and assembly: barrels and cabins arrive on a truck and weigh hundreds of kilograms.
- The base: a level, drained base of pavers, gravel, a slab or ground screws for an outdoor sauna.
- Electrics: a dedicated circuit, cable and isolator, installed by a licensed electrician; large heaters may need a bigger supply (electrical requirements).
- Permits: outdoor buildings and wood stoves can need approval; check your local rules before you order.
- Stones and accessories: stones are often not included, nor are the bucket, ladle, thermometer, lights and backrests.
- A chimney for a wood stove: an insulated flue and a roof or wall kit.
How to spend less without regrets
- Pick the type for your climate and use: a barrel heats a small group quickly; a cabin with a changing room suits long winters (barrel vs cabin).
- Do the inside yourself: panelling and benches are the most forgiving parts of a build; leave the electrics to an electrician.
- Size the heater to the room, not to the biggest model the budget allows.
- Insulate well: it lowers every future session's cost.
