Steam Saunas Done Right
A steam sauna is a wet-heat room. Instead of hot rocks, a steam generator fills the room with warm, moist steam, so the air stays humid and a little cooler than a dry sauna. San Francisco Sauna builds steam saunas and steam showers across San Francisco. These rooms need real waterproofing, so we build them with sealed, sloped tile, proper drainage, a vapor-tight ceiling, and a steam generator sized to the space. We can build a standalone steam room or turn a shower into a steam shower you can use every day. Because a steam room holds moisture, the sealing and drainage matter even more than in a dry sauna, and that is exactly the part we get right. If you like a softer, humid heat that is easy on the lungs, a steam sauna is a great fit.
Why Go With Us
Steam rooms live and die on the waterproofing, and that is our focus. We build vapor-tight rooms with sealed, sloped tile, real drainage, and a steam generator sized to the space. We are licensed and insured and handle the tile, plumbing, and controls with one crew, so there are no leaks and no finger-pointing. This is one part of what we do as everything we build, and it often goes hand in hand with a traditional dry sauna.

How We Work
From the first drawing to your first steam, we keep it simple and clear.
1. We plan the wet room
We look at the space and plan a room that can handle constant moisture: the tile, the slope, the drain, and the steam generator sized to the room. You approve the plan and finishes.
2. We waterproof and pipe
We build the room vapor-tight, waterproof and slope the floor to the drain, and run the water and power the steam generator needs. We pull the city permits and set up inspections.
3. We install and test
We set the steam generator and controls, finish the tile and bench, and test for steam and leaks. Then we show you how to run it and keep it clean.
What We Cover
Steam Generators
We size the generator to the room so it fills with steam fast and holds it.
Waterproofing and Tile
Vapor-tight ceilings, sealed and sloped tile, and a proper drain keep moisture where it belongs.
Steam Showers
We can turn a shower into a daily-use steam shower, plus a normal shower when you want one.
What Affects the Cost of Steam Saunas
A few things set the price of a steam sauna or steam shower:
- Size. A small steam shower costs less than a large standalone steam room.
- The steam generator. Bigger rooms need a bigger unit and more power and water.
- Waterproofing and tile. Sealing, sloping, and finishing a wet room is careful work.
- Plumbing and drainage. A new drain and supply lines add to the cost.
- Controls and extras. Digital controls, lighting, and a bench add up.
- Permits. City fees depend on the plumbing and electrical, and we handle them.
After we see the space, you get one flat price for the whole wet room.
Frequently Asked Questions
What is the difference between a steam sauna and a dry sauna?
A steam sauna uses a steam generator to fill the room with warm, moist air, so it stays humid and a bit cooler. A dry sauna uses a sauna heater and rocks and runs hotter with lower humidity between pours. Steam is softer and easy on the lungs. Dry heat is more intense. It comes down to which feel you like.
Can you turn my shower into a steam shower?
Often, yes. We check that the space can be made vapor-tight and drained properly, then we waterproof it, add a steam generator and controls, and finish the tile. The result is a steam shower you can use every day, plus a normal shower when you want one.
Do steam rooms need special waterproofing?
Yes, more than a dry sauna. A steam room holds moisture all the time, so it needs a vapor-tight ceiling, fully sealed and sloped tile, and a real drain. Skipping that leads to leaks and mold. Getting the waterproofing right is the core of the job, and it is what we focus on.
How much does a home sauna installation cost?
For a steam room, the big drivers are size, the steam generator, and the tile and waterproofing work. A small steam shower costs less than a large standalone room. After we see the space, you get one flat price that covers the build, plumbing, controls, and permits.
