Easy to build yourself.

Flush fitting and completely watertight.

Floor-level shower

A flush-fitting shower tray gives your bathroom a modern design and makes it easy to access the shower area. It is just as easy to install a floor-level shower.

Qboard® liquid offers the right element and correct floor drain for any installation situation. The fall is already integrated and can easily be tiled in the next step.

... and here's how to do it:

Qboard liquid Duschelement einbauen: Schritt 1

Connect the floor drain to the drain pipe and align it height-wise.

Fill in the screed recess with cement based levelling screed and trowel it up to the corresponding height.

Seal all joints with Qboard® sealing tape.

Questions & Answers

Qboard® is waterproof thanks to its XPS core. Only butt joints need to be sealed. Use the Qboard® sealing kit for this.

Alternatively, butt joints can also be sealed with Qboard® sealing tape (or equivalent) using a suitable liquid composite sealant (such as a mineral sealant).

Horizontal drain: approx. 0.8 l/s
Vertical drain: approx. 0.8 l/s


The overall height of the Qboard® liquid shower element including the floor drain depends on the size of the shower element and the drain used. The overall height of a shower element with a horizontal drain is between 110 - 125 mm.

The drain for a shower element with a vertical drain can also be fully sunk into a hole drilled into the concrete surface. Then the installation height will just be 45 or 55 mm (40 or 50 mm shower element + 5 mm bonding mortar).

The exact details of installation heights can be found on the last page of our instructions for use.
