Schluter Shower Installation



Step by step instructions on the Schluter Shower Installation:

1. After locating the correct position for the drain, cut a hole in the substrate using shower tray as a template.

2. Apply unmodified thin-set mortar to the substrate using a 1/4" x 3/8" (6 mm x 10 mm) square- or U-notched trowel. The floor must be level. Any leveling must be done prior to placing the tray.

3. Place the shower tray and solidly embed in the mortar.

4. Check the underside of the tray to ensure that full coverage and support are achieved.

5. Install Kerdi Band waterproofing seam strip at all tray/wall and wall/ceiling connections with mortar.

6. Install Kerdi Kereck pre-formed corners at inside corners.

7. Install Kerdi Waterproofing Membrane with mortar on all walls. Seams can be handled one of two ways: overlap Kerdi Membrane by 2" or butt sheets of Kerdi Membrane together and install Kerdi Band waterproofing seam strip over the joint.

8. Install Kerdi PS pipe seals at showerhead, body sprays, etc.

9. Install Kerdi MV mixing valve seal at the mixing valve. As an alternative, Kerdi Fix or equivalent sealant can be used to seal pipe protrusions and protect moisture-sensitive solid backing panels at the mixing valve.

10. If there is access to the plumbing from below and the waste line can be connected after installing the shower drain, apply unmodified thin-set mortar to the entire shower tray surface.

11. Press the shower drain firmly into the thin-set mortar, ensuring full support of the bonding flange.

12. When using the ABS or PVC drain, apply additional unmodified thin-set mortar to the top of the fleece-laminated bonding flange. When using the stainless steel drain, Kerdi Membrane is adhered to the bonding flange with the Kerdi Fix adhesive/sealant. The stainless steel bonding flange must be clean and free of grease or other contaminants prior to Kerdi Fix application.

13. Embed the Kerdi waterproofing membrane into the mortar and work the matting onto the entire surface of the tray to ensure proper adhesion and to remove air pockets. Be sure the connection between the membrane and drain is secure.

14. If necessary, cut the shower curb to length using a handsaw. Apply unmodified thin-set mortar to the floor and to the edge of the shower tray and walls using a 1/4" x 3/8" (6 mm x 10 mm) square- or U-notched trowel, and press the curb firmly into place. Check the underside of the curb to ensure that full coverage and support is achieved.

15. Use Kerdi Kereck pre-formed inside and outside corners to seal the shower curb to the walls and tray. The curb/tray junction is sealed using Kerdi Band waterproofing seam strip. Cover the entire curb with Kerdi Membrane.

The Schluter Shower Installation is now complete. Prior to setting tile, wait 24 hours minimum before water testing to allow for final set of thin-set mortar and ensure waterproof performance at seams and connections. The Schluter Shower Installation wasn't that bad was it?

Before and during tile installation, the tray and Kerdi Membrane must be protected in a suitable manner (e.g., cardboard can be laid over the floor to protect against mechanical damage). Using a trowel that is appropriate for the size of the tile, apply unmodified thin-set mortar directly to the exposed Kerdi Membrane surface and install the tiles, ensuring full coverage.

The drain grate assembly is installed in conjunction with the tile. Place the height adjustment collar inside the lateral adjustment ring and snap the grate into place. Fill the step in the bonding flange with thin-set mortar and back-butter the underside of the grate to ensure full support. Press the assembly into the mortar and install the surrounding tiles. Position the grate to match the joint pattern of the tile covering and press flush with the tile surface.

Congratulations on your Schluter Shower Installation!
