Steam Shower Cost: What to Budget in 2026
Most homeowners should plan on roughly $3,000 to $7,000 for a prefab steam shower installed in a bathroom that is already sound, and $8,000 to $20,000 or more when the enclosure, electrical and finishes are built from scratch. The spread is wide because published figures measure different things: some count only the generator, others the whole room. This guide breaks the number into its parts so you can tell which figure applies to your house.
TL;DR
- Published ranges cluster between about $2,000 and $7,000 for equipment-led installs, and between $6,000 and $20,000+ for complete custom projects.
- Converting an ordinary shower is the expensive surprise: the enclosure has to be steam-tight and the generator needs its own 240V circuit.
- Running costs are small. Expect well under $1 per session in electricity.
- Poor installation, not the equipment, is what usually fails. Budget for licensed trades.
- A steam shower is a luxury feature. Treat it as a comfort purchase, not a guaranteed resale gain.

What a steam shower costs: the ranges you will see
Search for the price and you will find numbers that seem to contradict each other. They do not, once you see what each one covers.
| Source | What it reports |
|---|---|
| HomeGuide | $2,900 to $6,800 for a prefab steam shower installed; $2,300 to $16,500 for a custom build or converting an existing shower |
| This Old House | Average of $4,300, with a normal range of $2,800 to $7,100 |
| Domino | A main range of $2,000 to $7,000 from an industry veteran, up to $10,000 with extras |
| Angi | $2,800 to $7,100, and up to $25,000 at the top end |
| Art of Steam | $6,000 to $20,000+ for complete projects, with $6,000 to $10,000 for a simple generator and controls install |
Two things stand out. First, the lowest figures come from sources that assume a standard enclosure or a prefab unit. Second, the highest come from full custom projects with premium tile, glass, smart controls and electrical upgrades. Some of these sources also sell steam equipment, so read their ranges as a guide, not a quote.
For planning, a sensible way to think about it:
- Entry level: a prefab unit or a generator added to a shower that already suits steam. Roughly $3,000 to $7,000 installed.
- Mid range: a generator, proper controls and a rebuilt enclosure in an existing bathroom. Roughly $8,000 to $15,000.
- High end: a larger custom enclosure with stone or large-format tile, bench seating, aromatherapy, lighting and audio. $15,000 to $20,000 and beyond.
These tiers are our synthesis of the published ranges above, not a quote for any specific house. Your local labor rates, the age of your home and your electrical panel will move the number.
Where the money goes
The steam generator and controls
The generator is the heart of the system. Its size depends on the volume of the enclosure, and the more tile, glass and stone you have, the more heat the room absorbs and the larger the unit must be. Controls range from a basic dial to touchscreen panels with timers and temperature presets. Equipment often makes up a minority of the total once labor and the enclosure are counted.
The enclosure
This is where budgets balloon. A steam room is not a shower with a hot-water gimmick. The enclosure must be waterproofed from ceiling to floor, and the ceiling must be sloped so condensation runs down the wall instead of dripping on you. One building-materials guide recommends about 1 inch of slope per foot and epoxy grout in place of standard sanded grout. A door that seals, glass that goes to the ceiling and a vapor barrier all add cost, and none of it is optional.
Electrical and plumbing
Most generators need a dedicated 240V circuit. If your panel is full or old, a sub-panel or an upgrade can add real money. Plumbing is usually modest: a water line to the generator and a drain. Your electrician and plumber should pull permits where your local building department requires them.
Finishes and extras
Tile, a bench, a built-in niche, a skylight-free ceiling finish, lighting rated for wet locations, a fragrance system and a glass door are where two identical steam showers end up $8,000 apart. Decide which of these you actually want before you collect bids, so every bidder prices the same room.
Converting an existing shower versus building new
Homeowners often ask whether a regular shower can become a steam shower. It can, but it is not a kit you bolt on. HomeGuide notes that the work can add about 25% or more to the cost of a bathroom remodel, because the enclosure needs to be fully steam-tight, the generator needs its own circuit and ventilation has to be handled correctly.
The cheapest conversions happen when:
- the shower is already a fully tiled enclosure with a ceiling you can finish,
- the walls are open anyway for a remodel,
- the panel has spare capacity near the bathroom,
- the generator can sit in a nearby cabinet, closet or vanity.
The most expensive happen when a shower with a open-top glass door or a standard fiberglass surround has to be torn out completely. At that point you are paying for a new bathroom shell, and it makes more sense to do it as part of a remodel. If you are weighing that, our bathroom remodeling page shows how we approach it, and our guide to wet room waterproofing covers the waterproofing logic that steam rooms share.
Why installation quality matters more than the brand
The cost you do not want is the second one: tearing out a failed enclosure. HomeGuide’s contractor sources point to poor installation as the most common failure, not the equipment. When the vapor seal is incomplete or the ceiling is not sloped, moisture reaches framing, and the results are mold and rot inside the wall where you cannot see them.
That is why a steam shower is a poor DIY project for the enclosure and electrical portions. A reasonable approach:
- Hire a licensed contractor to own the enclosure and waterproofing.
- Use a licensed electrician for the 240V circuit.
- Ask how the ceiling slope, vapor barrier and door seal will be handled, and get the answers in writing.
- Plan ventilation for the rest of the bathroom. Our guide on permit-ready bathroom ventilation explains what inspectors look for.
A small practical note for the finish stage: steam is hard on anything you hang near it. If you plan to decorate the surrounding wall, these placement rules for canvas art in steamy bathrooms help you keep pieces away from the worst of the moisture.
Running costs and upkeep
The good news comes after the install. MrSteam reports that a 20 to 30 minute steam session uses about 2 gallons of water, compared with 17 to 40+ gallons for a standard 20-minute shower, and that electricity generally runs under $1 per session. Its figure for daily users is $300 to $365 a year, and less for people who steam a few times a week. That is a manufacturer’s number, so treat it as a ballpark. Angi gives a more conservative estimate of about $24.50 a month on your electric bill for regular 30-minute sessions. Your local utility rate is what decides it.
Maintenance is mostly habit. Domino’s design experts point to squeegeeing surfaces after each use and having the generator inspected each year to protect the investment. Descaling matters where water is hard, and much of Washington and Iron Counties has hard water, so ask about a softener or a descaling routine before you buy. The same point applies to any steam generator: mineral buildup shortens its life.
Steam shower or sauna: which costs more
If you are choosing between the two, price is close, and the difference is how you want to feel.
| Steam shower | Sauna | |
|---|---|---|
| Heat | Moist, about 100 to 120°F | Dry, about 160 to 220°F |
| Typical installed cost | $2,800 to $7,100, up to $25,000 | $2,500 to $7,000, up to $10,000 |
| Where it goes | Inside a bathroom shower enclosure | Needs its own room or space |
| Main installation risk | Moisture and vapor sealing | Electrical load and ventilation |
The figures come from Angi’s comparison. A steam shower has the higher ceiling because it is built into a wet room, and moisture control is demanding. A sauna’s cost is more predictable, but you need floor space for it. If your bathroom is already being remodeled, a steam shower uses space you have already committed to. If you have a spare corner of a basement, a sauna may be simpler.
Pros and cons before you commit
What people like
- A spa-like routine at home, with no membership.
- Low water use compared with a long shower.
- A feature that buyers in some markets look for. Design experts told Domino it can raise the appeal of a home, though it is a luxury and not a guaranteed return.
What to weigh
- The upfront cost, which is substantial compared with a standard shower.
- The need for routine upkeep and a generator that will eventually need service.
- Moisture risk if the install is not done right.
- Health limits. Verywell Health reports that people with heart disease, high blood pressure or conditions such as asthma should talk to a healthcare provider before using steam, and pregnant people should avoid it unless their doctor clears it. The same source suggests five to 10 minutes for a first session, and 15 to 20 minutes for most healthy adults after that.
If anyone in your household has a heart or breathing condition, ask your doctor before you spend the money. It is a cheap question compared with the remodel.
Our perspective: plan the steam shower as part of the bathroom
We build and remodel homes across Washington and Iron Counties, and the pattern we see with luxury bathroom features is consistent: the feature itself is rarely the problem. The problem is that it was added late. A steam generator needs a circuit, a place to live, a sloped ceiling and a sealed enclosure, and every one of those decisions is cheaper on paper than in drywall.
So we encourage homeowners to decide early. If a steam shower is on your wish list, say so in the first consultation, before the layout, vanity and tile are locked. Our process uses virtual consultations and 3D renderings so you can see the enclosure, the door and the bench before anything is built, and one team handles both design and construction, which keeps the waterproofing and electrical details from falling between trades.
Our honest advice on budget: start from the whole bathroom and add the steam. Our published small bathroom remodel range is $10,000 to $15,000, and a primary bathroom is quoted per project. A steam enclosure is a premium feature that sits on top of that, so it belongs with the larger, primary-bath scope, not a quick refresh. If you are still deciding whether the investment pays back, our guides on bathroom remodel ROI and how a bathroom remodel affects home value set realistic expectations.

How to budget without surprises
- Define the room. Size, finishes and extras. Write them down so every bid covers the same scope.
- Check your panel. Ask an electrician whether there is room for a 240V circuit near the bathroom.
- Choose the generator location. A nearby closet or vanity cabinet keeps lines short and service easy.
- Get itemized bids. Look for separate lines for the generator, enclosure waterproofing, electrical, tile and permits.
- Add a contingency. Opening walls in an older home can reveal framing or wiring problems. A contingency of 10% to 15% is a common planning habit, not a rule.
- Pair it with comfort upgrades. A heated floor and a curbless entry pair well with steam. See our budgets for heated bathroom floors and curbless showers.

FAQ
How much does a steam shower cost to install?
Most published ranges land between about $2,800 and $7,100 for a typical installation. Full custom builds run $6,000 to $20,000 or more. The difference is almost entirely the enclosure, electrical work and finishes.
Is a steam shower worth the money?
It is worth it if you will use it regularly and value the comfort. It is a luxury feature, so do not count on recovering the full cost at resale. Running costs are low, but upkeep and a professional install are part of the real price.
Can you turn a regular shower into a steam shower?
Yes, but only with real construction. The enclosure must be sealed against steam, the ceiling sloped and the generator wired on its own 240V circuit. If your shower already has a tiled, full-height enclosure, the job is simpler and cheaper.
What are the downsides of a steam shower?
The main ones are the upfront cost, the maintenance and the risk of moisture damage if installed badly. Steam is also not suitable for everyone, so people with heart conditions, high blood pressure, asthma or pregnancy should check with a doctor first.
