Tips on building your own steam shower | trend4homy

Building your own steam shower can be a fun and challenging experience. To help you build your own steam shower here are some helpful tips that you can follow.

Steam Shower Ceiling Height:

Steam is lazy and wants to keep rising. So the shorter the ceiling, the easier and faster it is for your steam shower to get filled up with steam (and start to feel comfortable and warm). If you have a higher ceiling that is ok, but with a few important caveats. 

The ideal height for a steam shower ceiling height is 8 feet or under. Most steam shower sizing guides are setup for an 8 foot ceiling. Though you can plug into a steam shower calculator 9 or 10 feet, in reality at each foot increment above 8 you should increase the size generator. 

For example, the Superior Steam Generator sizing guide recommends doing L x W X H (and remember this is cubic FEET and not inches). Then it recommends doubling the number you get. So if you have a standard 4 foot Long, 3 foot wide, and 8 foot high shower you get 96 cubic feet. Double that and we are at 192 nominal cubic feet. And we go with a 6kw steam shower generator

If that same shower is 9 feet tall instead of 8 feet tall, though you are still within the threshold for a 6kw steam generator, it would be recommended to jump up 1 size to a 9kw unit. This would provide more steam to fill that upper space of the shower. Remember the steam is lazy and is going to keep rising. So we need to really fill in that upper section of the shower so it billows down to the space where you are standing and relaxing. 

Windows and skylights are also important: If it can be avoided it is best that you refrain from putting a window on your steam room.

If you really wish to put a window on your shower room make sure it has the highest possible R-value and ask the steam manufacturer what size generator they recommend.

Experts said skylights should be avoided inside a steam room. But if you already have a  skylight or cathedral ceiling, consider building a roof above the steam shower but below the bathroom ceiling. You actually have two options: construct the roof as a shelf with the same bath tile or check with your shower door manufacturer to see if they can supply a glass ceiling.

The shower door is also significant: Based on studies, the door usually seals off the shower from the rest of the bath area, leaving your steam shower effectively an unheated space. With this scenario, a steam shower with an outside wall will be very cold in the winter if the door is left closed.

As a solution to this problem leaves the door open, which means allowing enough space for the door to swing out into the room. However, if you have no intention of leaving the door open just add a  transom to the top of the door or install radiant heat. This action will not only regulate temperature but also allow the shower to dry so as to prevent mildew.

Steam generator location also matters: For a better result a steam shower generator should be closer to the shower ideally 25 feet away or less.

For ideal service access, a  nearby closet is the best location. It is also best that space must be indoors and protected from extreme temperatures. Experts also reveal that in order to operate a steam generator you need both a water line and a dedicated power line. The experts said having a drain connection is an option, but it can increase the life of the generator with regular maintenance, especially if you have hard water.

It is also important to note that the main difference between a regular shower and a steam shower is the intensity of the moisture, so materials, design, and quality of construction really matter.

The experts said regular steam room walls consist of a backer board, a vapor barrier or membrane, cement, grout, and tile, but you have some choices when it comes to materials and methods.

What pitch recommendation of the ceiling for a steam shower: If the steam shower ceiling should be angled a little bit, what pitch it should be.

The ceiling should be sloped to prevent dripping of condensate. The Tile Council of North America and the Marble Institute of America suggest between ½” to 2” per foot depending on the ceiling material.
