Planning the plumbing, pre-fitting pipe, and a series of foam spacers take the pain out of a potential remodeling pain in the neck

When there is no access to the plumbing from below Schluter KERDI-DRAIN is installed to the appropriate height and connected to the waste line prior to the installation of the shower base.

Here's how to do it in conjunction with the Schluter Kerdi shower prefabricated shower trays. The plumbing is in place and must be secured prior to installation.

The center section of the KERDI-SHOWER tray can be removed and used to establish the appropriate elevation of the KERDI-DRAIN.

Measure and cut a section of pipe to connect the KERDI-DRAIN to the odor trap below the floor.

Assemble the components and verify the fit.

You can also use one of the two sets of foam spacers included with the drain. They are designed to position the drain at the appropriate elevation. This can be advantageous on projects where the KERDI-SHOWER trays may not be installed immediately. Please reference the spacer selection sheet included in the drain box. Make sure to use the correct set based on the particular shower tray being installed.

Prepare the odor trap.

Cut a section of pipe and KERDI-DRAIN with cleaner, primer, and ABS or PVC cement per the solvent cement manufacturer’s instructions.

Attach the cut section of pipe to the drain.

Connect the assembly to the waistline using a twisting motion.

Apply thin-set mortar to the substrate, and then apply it to the top and bottom of the detached center section of the shower tray.

Slide the center section into place under the drain to ensure solid and uniform support of the bonding flange.

Clean away excess mortar.

Check that the drain is level.

The KERDI-SHOWER tray can now be installed and work on the shower assembly may continue.
