This article was updated using automation technology and thoroughly reviewed for accuracy by HomeAdvisor Editor Ryan Noonan.

Thinking about bringing spa-level relaxation home? Installing a steam shower costs between $2,800 and $7,100 for most homeowners, or $70 per square foot. Your final price depends on the size of the stall, the materials you select, and any extras you incorporate. A licensed shower installation pro will handle the plumbing and electrical work so you can start steaming—safely and sooner.

Steam Shower Installation Cost Factors

Several factors, in addition to the steam shower unit, influence your total project cost. These include lighting, controls, materials, flushing systems, and upgrades like sound systems or seating.

Size

Plan to budget $70 per square foot for your steam shower. The more square footage you give the shower, the more you’ll spend—so measure carefully before you start shopping.

Materials

Stick with ceramic or porcelain tile if you’re watching the budget. If you want a high-end look, consider granite, marble, or slate to add a luxurious feel, but be aware that they’ll increase your total cost.

Lighting

Lighting prices swing with your style picks. Hidden LEDs keep costs low and tuck neatly into the ceiling or under a bench. Splurge on recessed, color-changing fixtures for a starry, spa-like vibe.

Controls

Manual controls are the wallet-friendly pick. Go wireless or smart only if you’re ready to pay more for the added technology.

Flushing

Automatic flushing reduces calcium buildup and eliminates the need for manual scrubbing of the generator every 20 sessions. Stick with a manual flush only if you don’t mind the extra maintenance.

Professional Labor Costs

You’ll need several pros for a proper steam shower installation. Electricians charge $50 to $100 per hour, providing expertise to safely and securely install the generator and electrical components. A plumber costs $45 to $200 per hour to ensure your steam shower integrates seamlessly with your home's plumbing system.

Upgrades

Leave some room in your budget for fun extras—think built-in speakers, a molded seat, or an aromatherapy well—if you’re aiming for a resort-level feel.

Converting a Regular Shower

Converting a standard shower to a steam shower costs an average of $4,300, which includes the unit, steam generator, and labor.

Steam Shower Cost by Type

Your costs will vary depending on whether you install a prefabricated steam shower model or opt for a custom option. The table below outlines the costs associated with each type.

Prefab Steam Shower Cost

Prefab steam showers range from $2,800 to $7,100 for a basic model. Luxury models with features like jetted tubs can cost up to $10,000. The total cost depends on the features and quality of the unit you choose.

Custom Steam Shower Cost

Custom steam showers cost between $4,000 and $14,000, but high-end designs with intricate tile work or deluxe tubs can reach $25,000. The final price depends on the complexity of the design and the materials used.

Steam Shower Installation Cost per Component

Steam showers consist of several key components, each with its own price range. Here’s a breakdown of the cost ranges by component.

Shower Door and Glass Walls

Glass walls cost between $700 and $1,900, and glass shower doors range from $550 to $1,350. Thicker glass, such as 1/2-inch, is more expensive than thinner options, like 3/8-inch. The type of glass also impacts the price—clear glass is less costly, while specialty options, such as rain glass, are more expensive.

Wall Tiles

Installing shower wall tiles costs $5 to $16 per square foot on average, including labor. Non-porous tiles, such as ceramic and porcelain, are ideal choices for steam showers. Hiring a local bathroom tiling contractor ensures that the surfaces are properly sealed and sloped to direct water toward the drain.

Steam Generator

A steam generator costs between $600 and $2,500, depending on its power and capacity. Purchasing a generator as part of a package that includes the control panel, pressure release valves, and steam heads can save you money.

Cost to Build a Steam Room

If you want to take your steam experience to the next level, building a steam room costs between $22 and $65 per square foot, including materials and labor. Custom steam rooms with high-end features can cost up to $130 per square foot. Converting an existing shower into a steam room costs $2,600, depending on the size.

Does a Steam Shower Increase Home Value?

A steam shower can pay off in terms of comfort and increased resale value. Homes with a steam shower sell for up to 29% more, and some homeowners see up to a 70% ROI. A steam shower adds a spa-like appeal that can attract wellness-focused buyers and elevate the overall bathroom experience. Still, the real win is the daily spa-level relaxation, so weigh that personal perk against the initial price tag before making a decision.

DIY vs. Hiring a Steam Shower Pro

If you’re handy, a prefab steam shower kit, including a generator, runs $2,800. Just remember you’ll still need a licensed electrician and plumber to hook everything up, so the savings are often minimal. Hiring a professional local shower installer is best for a safe and efficient installation. Professional installation will also maintain your home’s integrity by sealing your walls from leaks and water damage.

Get started with a local steam shower professional to ensure the job is done right.
