A steam shower combo is a sealed shower cabin with its own steam generator, so the same space works as a normal shower and as a steam room. Most come as a complete kit: glass enclosure, base, seat, jets and the generator. The other route is a steam kit that turns an existing, fully enclosed shower into a steam shower. Here are four options on Amazon now, with what each listing says.
Our quick picks
- Best for two: Mesa 803A Steam Shower. 54 x 35 x 85 inches, a 3kW steam generator, rainfall head and foot massager.
- No 220V circuit: Mesa 803L 2-Person Steam Shower. The same 3kW generator on a 120V, 15 amp plug, with 2 hand wands and 12 body jets.
- Convert your shower: Delta SimpleSteam 10kW Kit. Generator, digital control and steam head for an enclosed shower you already have.
How we picked: we haven’t installed or tested these steam showers. We compared the current Amazon listings, and where a listing was thin, the specs a Mesa dealer publishes for the same model. We only included models in stock in the US when we checked. How we review.

The best steam shower combos on Amazon
1. Mesa 803A: best for two
A rectangular walk-in cabin, 54 x 35 x 85 inches per its Amazon listing, with a 3kW steam generator, a rainfall shower head, FM radio and a foot massager. It’s ETL/CSA certified and plugs into a 220V, 15 amp outlet. West Coast Saunas, a Mesa dealer, lists bench seating for two and 12 body jets, and says it comes in left- and right-hand versions, so check which side your drain is on.
2. Mesa 803L 2-Person: no 220V circuit needed
The 803L is the pick if you don’t want to run a 220V line. Its listing gives the same 3kW steam generator on a 120V, 15 amp plug, with 2 adjustable hand-held shower wands, 12 acupuncture body jets and a built-in FM radio. Like the 803A, it’s ETL/CSA certified.
3. Mesa 9090K: corner cabin
For a bathroom corner, the 9090K has sliding tempered-glass doors, a 3kW steam generator, aromatherapy and a fold-up seat, per its listing. The Amazon listing doesn’t give its dimensions or power supply, so ask the seller for the spec sheet before you order.
4. Delta SimpleSteam 10kW Kit: convert the shower you have
If you already have a shower with glass to the ceiling, a steam kit is usually cheaper than a whole new cabin. This Delta kit includes the SimpleSteam generator, a square digital control and a square steam head. Delta says the compact generator can go in a vanity, a closet or an insulated attic or basement, and the kit comes with a 35-foot cable. The generator is also sold in 4, 6, 7.5, 12 and 15kW sizes: the right size depends on your shower’s volume and wall material, so check Delta’s sizing guide.
Cabin or steam kit?
- A complete cabin arrives with everything sealed and matched. It suits a remodel or a new bathroom, and it’s one box to install. You need the floor space, the ceiling height (around 85 inches for the 803A) and a drain in the right place.
- A steam kit uses the shower you have. The enclosure must be fully sealed to the ceiling, with a door that closes tight and a sloped ceiling so condensation doesn’t drip on you. It’s usually the better buy if the shower is already tiled and sound.
What installation involves
Plan for a plumber and an electrician. A steam shower needs a hot and cold water supply, a drain, and its own electrical circuit to the rating on the listing: the 803A needs 220V and the 803L 120V, both at 15 amps. Cabins arrive in large crates and need two or more people to carry and assemble. Check that the unit fits through your doorways before you order, and that the floor can take the weight of the cabin full of water and people.
Steam shower or sauna?
A steam shower runs at a lower temperature with very high humidity, and it doubles as your everyday shower. A dry sauna is hotter with low humidity and needs its own space. If you’d rather have dry heat, see our guides to home infrared saunas and portable infrared saunas. Either way, read our guide to using a sauna safely before your first session.
Frequently asked questions
What is a steam shower combo?
A shower cabin with a built-in steam generator, so the same enclosure works as a normal shower and as a steam room. Most come as a complete kit with glass, base, seat and jets.
Do steam showers need a 220V circuit?
Many do. The Mesa 803A lists a 220V, 15 amp plug. The Mesa 803L lists a 120V, 15 amp plug, so it can run without a 220V line. Larger steam generators for kits usually need a dedicated 240V circuit.
Can I turn my existing shower into a steam shower?
Yes, if it’s fully enclosed to the ceiling with a tight door. A kit like the Delta SimpleSteam adds a generator, a control and a steam head. The generator can sit in a vanity, closet, attic or basement, per Delta.
How big is a two-person steam shower?
The Mesa 803A is 54 x 35 x 85 inches, per its Amazon listing. Measure your floor space, ceiling height and doorways before you order.
Do I need a professional to install a steam shower?
It’s strongly advised. You need plumbing for hot and cold water and a drain, plus a dedicated electrical circuit, and the cabin is heavy to move and assemble.
