How We Chose the Best Steam Showers

There are a couple of ways to set up a steam shower: You can build a new shower cubicle or convert an existing one. Converting an existing shower is the simplest approach, but a capable DIYer could consider installing a new bathroom enclosure using a shower kit. But since DIY-ing isn’t for everyone, hiring a professional contractor is always an option.

We looked for solutions to meet a variety of needs as we assembled this list. For each model, we considered power output, controls, user-friendly features, and of course, cost. We also analyzed owner feedback from several sources to check reliability.

To ensure we fully understood every aspect of the best steam showers, we consulted several experts. Bathroom designer Thomas Borcherding of Homestar, Inc., a design and remodeling business in St. Louis, Missouri, says, “A steam shower creates concentrated water vapor that is looking for somewhere to go, so steam showers need to be waterproofed.” It’s an important point for DIYers, because escaped steam in walls or floors can eventually lead to dampness or rot. Oren Farkash, founder and CEO of South Land Remodeling, located in Los Angeles, California, agrees. “Steam showers need an extra layer of waterproofing placed under the tiles to handle extreme moisture.” He says, “Have the ceiling of a steam shower slightly slanted toward the back wall. This will eliminate water drops falling on you from the wet ceiling.”

What to Consider When Choosing a Steam Shower

The process of creating a steam shower can vary, whether it’s converting an existing shower to a complete DIY steam shower design and build, to having a professional install a prebuilt steam shower enclosure. Skill level, technical considerations, budget, and personal preferences will affect which approach is right for each person.

Power and Size

The power of the steam generator is measured in kilowatts (kW). The models considered for this list spanned the range from a small steam generator at 3kW to a high-performance 30kW unit. Some steam generator manufacturers give an estimate of the space their device is appropriate for in cubic feet, which can be very useful. Anything less than 5kW is probably insufficient for a full-size shower. For single-person spaces, 7.5kW to 9kW is a popular size. Those above 15kW are usually intended for larger walk-in steam showers or commercial installations. Shower materials such as stone or marble increase costs, making budget adherence more challenging. There are websites that offer calculators, but those making a large investment may wish to consult a professional.

Another aspect related to power is sometimes overlooked. Steam generators need a dedicated electrical supply, often 220/240V. Since this will usually require work at the breaker box, this may be a job best left to a professional.

Start Time and Auto Drain

Start time is the delay between turning on the steam generator to when enough steam for the shower space is produced. Picture an electric kettle if you will. More powerful kettles boil quickly, while others leave users waiting for ages. A steam generator is the same; somewhere between 3 and 5 minutes is common, though the most powerful steam generators can be ready in 60 seconds.

Auto-drain flushes the water out of the steam generator once it is turned off. This can prolong its working life by reducing corrosion and is healthier because it helps prevent mold or mildew. It’s worth checking the details carefully. Some steam generators include an auto-drain feature, while for others it comes at extra cost.

Additional Features

Features included will vary considerably depending on whether a user is adding a steam shower generator to an existing cubicle or buying a complete enclosure. A control panel is a must, but on some models, it needs to be purchased separately. Other features might include:

  • Wi-Fi compatibility for remote control;
  • Auto shutoff to prevent overheating if there is no water supply;
  • Built-in music player;
  • Chromotherapy (light therapy); and
  • Aromatherapy oil reservoir to scent the steam.


This article has provided information to help consumers decide on the best steam shower for their needs. If you still have questions about steam showers in general, you might find the answers to some frequently asked questions below to be helpful.

Q. How does a steam shower work?

A steam shower uses a steam generator to turn cold water into steam. This is then piped into a sealed shower cubicle. An existing shower can be converted, but fitting a new door may be necessary to keep the steam in.

Q. How long should you sit in a steam shower?

The experts we consulted agree you should sit in steam room showers for no more than 20 minutes, though some feel 10 minutes is sufficient. Make sure you are well hydrated beforehand. If you feel uncomfortable or nauseous, you should stop immediately. Those with heart or lung conditions should consult their medical practitioner before using a steam shower.

Q. How do you install a steam shower?

You can either use an existing enclosed shower cubicle or create a new one. Then the steam generator needs to be fitted outside it, with the necessary plumbing and electrical supply. While this may be fairly straightforward for experienced DIY enthusiasts, those without complete confidence may benefit from employing a suitably qualified contractor.
