What are Steam Showers?

Steam showers supply a continuous stream of relaxing, spa-like steam to elevate your morning or evening routine. It can be an added component of a standard shower or installed as a separate standalone unit in your bathroom.

  • Built-in control settings for a custom experience

  • Helps with relaxation and stress relief

  • Soothes sore muscles

  • Improves resale value

A steam shower requires water and electricity to operate, as well as a sealed enclosure to maintain a constant temperature and humidity. While it is possible to retrofit an existing shower and bathtub into a steam shower, it will require a sealed door and enclosure plus connections to your home’s water supply and electrical system.

You will also need a backer board and vapor barrier to prevent moisture buildup behind the walls, in addition to tile or stone along the shower floor, walls, and ceiling. Because of the labor required, custom steam showers are often installed by a professional during a full bathroom remodel.

A prefabricated steam shower kit is another option. It is usually sold as a DIY package and includes the enclosure or stall, generator, steam head, valve, and control panel. Your bathroom should be large enough to accommodate the stall’s dimensions and provide easy access to plumbing and electricity. Installing a steam shower kit can be a DIY weekend project. But if adding or moving piping and wiring is required, you may need to consult with an electrician and plumber for professional assistance.

How Does a Steam Shower Work?

The technology behind a home steam shower is simple. A file box-sized generator draws water from your home’s plumbing system and heats it to 212 degrees Fahrenheit to produce steam. The generator then moves the steam to the showerhead that you control to release it into the stall according to your preferences.

You will need to have a dedicated space near the shower stall to keep the generator. A vanity cabinet, closet, or under a bench outside the stall are examples of good installation locations. Above the stall in an attic can also be an option, but only if the space is climate controlled and not susceptible to extreme temperatures.

Steam shower controls allow you to create your desired experience, depending on the unit you purchase. Steam shower settings and controls can be installed outside and inside the shower stall. Many steam shower owners prefer having controls in both locations to manage steam settings outside and inside the stall. Standard settings include:

  • Temperature control
  • Amount of steam
  • Shower duration

You can make it a multi-sensory experience with aromatherapy diffusers, music, and lighting.

How Much Does a Steam Shower Cost? 

On average, a steam shower in the home can cost between $2,600 to $14,500. The cost of a steam shower will vary depending on whether or not you choose a prefabricated unit or a custom design. Prefabricated steam showers can cost from $1,500 to $6,000, while custom units can cost from $6,000 to $14,500 or more, depending on the fixtures and materials. If part of a larger renovation, adding a steam shower will increase your total bathroom remodeling costs.

Steam Shower Costs
 Custom steam showerPrefab steam shower kit
Generator and parts$1,500 to $5,000$2,000 to $5,000
Materials and installation$1,000 to $15,000$600 to $1,000
The good news is that in addition to creating a spa-like sanctuary in your bathroom, installing a steam shower can boost your home’s resale value. Homes with listings that included a steam shower sold at a list price of 29% higher than homes without.

To build a custom steam shower, your bathroom may require demolition of an existing shower, plumbing and electrical labor, and installation of a shower enclosure, glass door, and tile work. Your desired shower size will be a big determining factor in your final cost, as it will affect the price you pay for the steam generator, parts, and materials.

A prefabricated steam shower kit comes in a complete kit and includes all materials and components. Your choice of design will be limited, and you will still need to budget for some electrical and plumbing work.

Steam Showers vs. Saunas

While both can be used for relaxation and stress relief, the main differences between a steam shower and a sauna are moisture and temperature. A steam shower is a high-humid environment that ranges from 110 to 115 degrees. A sauna provides a source of dry heat with temperatures from approximately 150 to 190 degrees.

Benefits of Steam Showers 

A steam shower can be good for your health and the planet. Here are a few of the top steam shower benefits.

Soothes muscles

Exposure to warm steam helps relax stiff or sore muscles. It can also assist with workout recovery and alleviate back and neck pain.

Reduces stress

Steam room use is linked to the reduction of cortisol, which is the body’s stress hormone. Installing a steam shower is an investment in your long-term health!

Illness recovery

Inhaling steam can help alleviate cold and flu symptoms including congestion, coughing, and body aches.

Improves complexion

Enjoy a facial in the comfort of your home. Steam unclogs pores and releases the buildup of dirt and oils. It also gently stimulates oil production to naturally hydrate skin, leaving you with a healthy-looking glow.

Conserves water

Steam showers will also help keep your water consumption and costs down. Steam showers consume only two gallons of water for approximately 30 minutes of use, while a standard shower requires two gallons of water per minute and an average bathtub of 30 gallons of water.

What to Look For in a Home Steam Shower 

While understanding how a steam shower works is straightforward, shopping for one may be confusing. Here are a few important things to think about when comparing manufacturers, models, and features.

Generator size

Your steam generator unit must have the power to heat the area of your shower stall. To determine how much power you will need, calculate your shower’s volume.

  1. Take and multiply your stall’s dimensions: Width x Length x Height.
  2. Your wall material will affect how much power you will need. For example, if using tile, multiply your stall’s volume from number one by 1.35 or 2.0 for marble.
  3. Exterior walls will also determine your power needs, since the generator will have to work harder to maintain a constant temperature inside the shower. Take your volume calculated from number two and multiply by 1.1 for one exterior wall or 1.2 for two.

Take your final adjusted cubic foot measurement and compare it to manufacturers’ recommendations. Generator sizes are measured in Kilowatts or KW — a larger shower requires a generator with more power. Generator sizes range from 7KW for a cubic foot range of 100 to 250, and up to 15KW for 550 to 675.

Heating element

How a generator produces steam is another important consideration. Different manufacturers will have different methods, so it is important to know what your priorities are to make the best decision to meet your needs.

Some generators will use a single heating element to create steam. Others may include two or more. Multiple heating elements allow for a constant stream of steam and prevent heat fluctuations to maintain your comfort and relaxation.


A steam shower control pad will turn the generator on and off and will allow you to control the shower’s temperature. Most controls will also include the option to adjust the volume of steam released into the stall as well as a timer.

Beyond the basic controls, you can upgrade your shower experience with optional features like a touch screen, remote control, and other luxurious option to transport you to your favorite day spa:

  • Wi-fi and/or Bluetooth capabilities for music 
  • Dimmable LED lights or chromotherapy lights for ambiance
  • Aromatherapy pump that atomizes your favorite essential oils for relaxing or mood-boosting scents

Self-cleaning capabilities

You will have to manually flush out your generator regularly to remove calcium deposits every 50 uses or so. For added convenience, look for steam shower manufacturers that offer self-cleaning features, like automatic line flushing of both the waterline and generator.

Are There Any Downsides to Steam Showers?

A steam shower in your bathroom is the ultimate luxury, but it also comes with more items to add to your chore and household maintenance lists. It is important to be aware of the following potential drawbacks.

Mold growth

A steam shower stall is a 100% humidity environment. This means it can quickly become a breeding ground for mold, mildew, and bacteria growth. It requires constant upkeep to keep it fresh and clean to maintain that invigorating spa-like feel.

Installing a generator with self-cleaning features will help, but it is only half the battle. To keep your steam shower functioning optimally, squeegee the tile and open the door to dry out the stall after each use. Wipe down the tile and grout with an appropriate cleaning solution at least once a week, and plan to reseal tile grout at least twice a year.


Some noise during steam operation is normal. You may hear steam moving from the generator to the shower valve and the valve releases steam into the stall.  Installing a water pressure regulator or adding insulation to the steam line can help reduce most noise. Other noises like buzzing or high-pitched sounds may indicate a problem with the steam generator that may require repairs or a warranty claim.

Can be expensive to maintain or repair

Because a steam shower requires tapping into your home’s water line, a malfunction could result in a serious plumbing problem. Water damage can be expensive to clean up and repair. If the problem went undetected, you may also have mold to remediate. Most manufacturer warranties offer protection against defects in materials and workmanship. However, be sure to read the fine print to understand their coverage limits.

Final Takeaways

Steam showers can make you feel amazing and increase your home’s resale value, but they may not be suitable for everyone. You should be in generally good health to withstand the heat and humidity of a steam shower. Pregnant people and those with underlying health conditions like high blood pressure, diabetes, or heart issues should consult their doctor before considering a steam shower for their home.
