If you are a designer or remodeler interested in learning more about the finer points of steam, you've come to the right place! This second chapter of our two-part educational series on steam showers turns up the heat on installation basics, and provides you with the resources you need to create an amazing customer experience with steam.
>>See Part One- Steam Showers 101: How To Turn a Bathroom Into a Wellness Retreat - where we talk about the wellness benefits of steam and provide a basic planning checklist to get your wheels turning.
One great thing about steam is that you can go as big or as small as you like in terms of the scope of the project. This applies to whether you are converting an existing shower into a personal steam shower spa and wellness retreat, or taking a blank slate and building out a brand new personal retreat.
Regardless, it's important to plan out the steam shower installation. You will want to consider the overall space, the interior, plumbing, electrical, the steam generator, materials and the rest of the room, including ventilation. Let's explore each step in detail.
When it comes to planning out the overall size of the space you will need for your steam shower installation, it's important to consider the size of the steam room as well as the materials to be used.
MrSteam’s formula for the volume of a steam shower is V=LxWxH which is important when selecting the ideally sized steam generator.
We also suggest considering Anthropometry for maximum comfort.
Anthropometry is “the scientific study of the measurements and proportions of the human body.”
In other words, don’t start by giving your customers a minimum size based on LxWxH. Instead, design for maximum comfort. Then, adjust the steam generator to fit that space. The minimum size comfortable for one person is 3' x 3' x 7'.

An 8' ceiling is optimal for a steam room.
The important thing to remember about ceiling height is that steam rises. If you design a room with a grandiose 13’ ceiling, your average height client won’t be standing in steam. The laws of physics dictate that the steam will be up near the ceiling.
You can go higher than 8’ – say up to 10’ – but the size of the generator has to be bumped up to compensate for that increased height.
One question we get asked often is whether a slope in the ceiling is required. Unless you are going to be using your home steam shower for more than 45 minutes at a time, we don’t think it’s necessary.
MrSteam offers several tools to help you figure out which steam generator will work best for your application. You will find them detailed in the resources section at the end of this article.
The interior of the steam room should be conducive to relaxation. That means that you should be comfortable for the entire steam session, in a seated position with controls within easy reach.
MrSteam recommends bench seating within a steam room, either built-in or a shower seat that folds up. You are looking for seating that is a minimum of 15” deep and 18” in height from the shower floor as you see in the sketch below.
The steam head should be placed 6” to 12” from the shower floor and on the opposite wall from the control as we just mentioned. It should also be placed away from the bather’s head, body and feet.
For the floor drain, you might consider linear drains as you see in the image below.
It's important to prevent mold and mildew from developing in a steam and bathroom environment. Good options include hot mopping, adding a vapor barrier or using a Closed Cell Membrane (e.g., Wedi-Board).

For more information, we encourage you to visit the Tile Council of North America website for frequently asked questions about steam rooms.
You should use brass or copper pipe only (no PVC or PEX). Plan for the following connections:
You will also want to lower the incoming water pressure if possible to (PRV) 15-25 PSI.
Be sure to use threaded unions for easier repairs. Threaded unions are highly recommended since a steam generator is an electromechanical device and you may need access.

You will need 240V (or 208V) household electric, most likely single phase and a dedicated circuit breaker. No GFI is necessary.
Where will you locate the steam generator? It can be in a heated attic space, in a closet, or even under a built-in shower bench as long as it is not exposed to the inside of the steam shower space. Be sure to review the electrical and plumbing requirements for the steam generator to determine the ideal placement for it.

As we mentioned above, materials matter. To maximize efficiency, it's best to choose non-porous materials such as tile and marble for the shower walls rather than porous ones such as slate and mesh-backed mosaics.
If you aren't sure, expose your materials to a soak-test. If they absorb water, they are porous and will require a larger steam generator.

Lighting can make a big difference in a steam room. If you plan on including lights, we recommend recessed task lighting using energy efficient halogen 75 watt lamps that are designed for steam room moisture and temperature levels. These lights offer a shower-rated trim & gasket and an attractive recessed ceiling mount for architectural integration. This lighting is US and Canadian Listed/ cETLus.
Here's an important question for you:
We also recommend a standard bathroom exhaust fan outside the steam shower, and louvers to help prevent mildew
If you have windows in the bathroom, we recommend double-paned for exterior windows.

Niches for shampoo and other shower items add beauty and utility to the shower space.
There are so many good reasons to choose steam – whether you’ve got a client who wants it for the holistic health benefits and is sold by the eco-friendly aspects of steam, or a client who is focused on the skin care benefits and is sold by the relaxation factor. Once you’ve gotten to the point in your client conversation where you’re ready to talk details, this is where you start discussing the steam generator, how to customize the steam experience and the look of the components.
