Home Steam Room Guide

A custom built steam room installation is the best and most flexible way to create the exact space you desire. 

This guide will give an general overview of how to create the perfect home steam room, it cannot cover the guidance/technical information pertaining to specific steam generators or controllers, please consult with your steam generator manufacturer for this information.   

Overview

A steam room can be created in almost any room and on any floor of the house. In its simplest form a steam room is a fully insulated and waterproof room with an outlet on the wall that disperses steam, but there is quite a lot that must be understood to design and install a steam room that functions correctly.

The Size of the Steam Room

You must consider how many people will be using the room and the seating arrangements, the room should not be bigger than it has to be. Smaller rooms typically heat up faster and if your room is too big it may take longer to heat even with a more powerful generator, you are also wasting energy. The ceiling height should be no more than 2440mm (8 feet) as steam rises.

Extractor Fans 

Installing an extractor fan is a good idea to disperse the steam after the room has been used. The fan should be IP X4 rated or an inline type mounted outside the steam room, always check with the manufacturer for suitability.      

Lighting

There are many forms of steam room lighting, ensure this is at least IP65 rated, always check with the manufacturer for suitability.

Shower

At the very least, consider a hand held shower, this will be useful when cleaning the room. 

The Floor

The floor should be treated in the same way as a wetroom floor, it must be have falls to take water away towards a drain. This is important as not only do you need to remove excess water caused by the steam, it will also be used to drain water when cleaning.
Our wetroom trays are perfect for this.
The rest of the floor should be level with the tray, normally this is done by using Tile Backer Board.
Tile Backer Board is used as it also insulates, which will increase the rooms warm up time.​

The Walls

The walls must be insulated, we recommend using 20mm Tile Backer Boards.

The Ceiling

The ceiling should be sloped to prevent water dripping, we recommend a slope of 25mm per 300mm (1 inch per foot).
The ceiling must be insulated, we recommend using 20mm Tile Backer Boards.

Seating

Our Seating Profiles are perfect for installation in a steam room.
You can even use fold up seats in smaller rooms.

Steam Generator Size

First work out the volume of room - Length x Width x Height = m³
All steam generators should have a recommended room size they are designed for, first look at  generators that match the room volume.
Consider the materials used in the steam room i.e. glazing, ceramics and marble, these types of materials effect warm up time/heat retention. You may benefit from going up a generator size.
Once the generator has been selected, ensure an appropriate dedicated electrical supply can be obtained.         

Steam Generator, Outlet and Controller Location

The generator should ideally be located in an adjacent room and must be accessible, it will also need a water supply and a drain connection.
The steam outlet is normally located around 300mm (1 foot) high on the wall, away from the entrance and seating away from users legs/feet.
The controls are usually mounted inside the steam room close to the seats for convenience, do not mount the controls above the steam outlet as they normally have a temperature sensor built in.        

Waterproofing

The entire steam room should be tanked, floor, walls, ceiling and seating.
Our Innovations Tanking System is ideal for this. 

The Steam Room Door

A glass door is usually installed, this should be sealed but a small amount of airflow around the door is fine.
We can offer bespoke frameless doors to fit any aperture required.

Tiles

We recommend 10mm tiles as these will heat up faster than thicker tiles and give you a quicker warm up time.
