Building a Steam Shower

The first and the foremost thing which you need to be before beginning the building process is to find a suitable location to place your steam generator.


  • You would need to find a select a serviceable area to mount the steam generator that is protected from freezing and moisture.
  • Avoid mounting a steam generator outdoors, inside the steamroom, or in an uninsulated attic

After selecting the location, you need to gather the material needed to build the Steamroom. You need to keep the following tips in mind while procuring the material for steam room.

Shower Installation

  • To ensure the integrity of the user control cables with Telco connector, they should be run through 3/4
  • PVC conduit or equivalent
  • Ceiling height should not exceed 8′-0″ when possible because of the inefficiency in heating the higher ceiling area. If the ceiling height does exceed 8′-0″, then use the next larger size model steam generator.
  • Ceiling should be sloped a minimum of 2″ per foot to prevent condensation from dripping on the bather, sometimes sloped from the center to minimize ceiling height reduction in larger rooms. The seat should also be sloped the same.
  • Steamroom walls, floor and ceiling must be completely enclosed and use a vapor-tight door. In a small steam shower, a 3/8″ air gap is recommended below the door and the door should incorporate a splashguard.
  • If installing exhaust fans or vents, they should be mounted outside of the steamroom
  • A floor drain must be provided for condensate run-off and cleaning
  • Steam outlet plumbing line should not exceed 25′-0″ and should be insulated when it is over 10′-0″. The line must never form a trap or gully, always angle toward the generator (preferably) or steam head.

Checklist for safe installation and better functioning

  • Avoid the use of exposed or untreated materials
  • Insulate all steamroom walls and ceiling
  • You would need to cover the steamroom walls, ceiling, and floor with waterproof finish, i.e., tile, marble, etc.
  • Seal all cracks and joints with a silicone sealer
