Steam Sauna Cost Guide: 2026 Prices

Steam saunas, also called steam rooms, use a generator to fill a sealed space with warm, humid air. Costs range widely, from an inexpensive portable pod to a fully built steam room. This guide covers what a steam sauna costs in 2026, the main types, and what it costs to run.

How much does a steam sauna cost?

Steam sauna prices split into three groups. Portable steam saunas, a foldable tent with a small steam generator, cost about $150 to $500. A residential steam generator on its own, to convert a shower or small enclosure, runs roughly $600 to $2,500 depending on the room size it serves. A complete built-in steam room, with the generator, a sealed enclosure, seating, tile or acrylic, and controls, typically costs $2,500 to $6,000 or more once installation is included. These are general market estimates, not our catalog prices, and plumbing, electrical, and waterproofing for a built-in room are separate. If you want the humid-heat experience without a build, a portable steam sauna is the easy entry point. Explore options in our steam saunas collection.

Price ranges by type

Type	Typical price	Notes
Portable steam sauna	$150 to $500	Foldable pod, plugs in, no install
Steam generator only	$600 to $2,500	Converts a shower or enclosure
Built-in steam room	$2,500 to $6,000+	Full enclosure plus install

What drives the price?

For portable units, the generator wattage and build quality matter most. For built-in rooms, the biggest cost drivers are the size of the space (which sets the generator size), the enclosure materials such as tile or acrylic, waterproofing, seating, and controls, plus the plumbing and electrical work to support it. A steam room is closer to a bathroom remodel than a plug-in appliance, which is why the installed cost climbs quickly.

What does a steam sauna cost to run?

Steam generators use both electricity and water. A residential generator often draws about 5 to 9 kilowatts while producing steam, though it cycles rather than running flat out. At the U.S. average residential electricity price of roughly 17 cents per kilowatt-hour reported by the U.S. Energy Information Administration, a 20 to 30 minute steam session commonly costs around 40 to 90 cents in electricity plus a small amount of water. Portable steam pods use far less because the generator is small.

Steam vs infrared: which fits your budget?

A portable steam sauna and a portable infrared unit cost about the same, but a built-in steam room is usually pricier and more involved to install than an infrared cabin, because it needs waterproofing and plumbing. Infrared cabins also plug in and use less energy. If you love humid heat, steam is worth it; if you want lower cost and simpler setup, compare our sauna vs steam room guide.

Frequently asked questions

Is a steam sauna more expensive than a dry sauna?

A built-in steam room usually costs more to install than a comparable infrared cabin because of plumbing and waterproofing. Portable steam and portable infrared units are priced similarly.

Do steam saunas need plumbing?

Built-in steam rooms need a water supply and drainage plus a dedicated circuit. Portable steam pods only need an outlet and a jug of water for the generator.

Are portable steam saunas worth it?

For an affordable way to enjoy humid heat at home without a remodel, yes. They deliver a lighter experience than a full room but cost a fraction of the price.
