How to Install a Schluter Shower System

The majority of homeowners prefer the natural beauty of stone and tile over the pre-shaped plastic tub surrounds. This is true, especially for a luxury bathroom design.

After the master bath was remodeled, we chose to go with a Schluter shower system for this project.

After the bathroom contractors had gutted the old bathroom and roughed in the tub and shower areas the Schluter drain pan could be installed.

  1. Unmodified thin-set mortar was spread onto the shower substrate floor. Next, the Schluter-KERDI SHOWER TRAY (Schluter-KERDI-SHOWER-ST) was laid and pressed into place in the bed of a thin-set.
  2. Next Schluter-KERDI-BAND Waterproofing strip was affixed, using thin-set mortar, to every seam where the wall met the floor and where the wall met the wall to secure a proper seal.
  3. Following that, the walls were covered Schluter-KERDI Waterproofing membrane. To do this the walls were troweled with thin-set. Then the thin layer of waterproofing material was unrolled over the prepped walls. The edge of each new piece of waterproofing membrane overlapped the previous piece by two inches. This sealed all the walls in the shower area so that they would be protected from moisture and vapor infiltration.

    *Note: Schluter-KERDI can be used directly over regular drywall. When installed properly the waterproof membrane will completely protect a tiled shower wall from moisture and water.

  4. The Schluter-KERDI-DRAIN was installed and the waste line was connected. This Schluter floor drain has a sloped, integrated bonding flange. The entire shower tray then had a layer of unmodified thin-set mortar applied to its surface. The shower floor was then covered with the Schluter-KERDI Waterproofing membrane.
  5. Then, the Schluter-KERDI SHOWER CURB (Schluter-KERDI-SHOWER-SC) was cut to the proper length and installed. This curb provides a ledge that will keep water in the shower and will support the glass door.
  6. The KERDI shower curb then had the waterproofing membrane applied to it with a thin-set. Careful attention was given to sealing all of the junctions where the curb met the wall and floor.

    *Note: Schluter-KERDI-SHOWER curb is made from EPS (expanded polystyrene) foam. It has 57 psi of compressive strength and can support tile and glass shower doors.

  7. The shower stall was then tiled and grouted as usual.
  8. Finally, the glass walls and door were installed for the shower. **

Varying the size and shape of the tile or stone used in a bathroom remodel offers rich texture and appealing visual focal points. The smaller tile that was installed at the base of the jacuzzi tub looks sensational.

We tiled the shower stall and incorporated a Schluter-KERDI Shower tray and curb under the tile.
