The Schluter-KERDI-SHOWER-R shower ramp is a simple way to create a curbless shower application.
KERDI-SHOWER-R is a lightweight, expanded polystyrene shower ramp with integrated KERDI
waterproofing, specifically designed to integrate with the Schluter-Shower System.
In this installation, the shower ramp will be used in conjunction with the Schluter®-KERDI-SHOWER
prefabricated shower tray. The shower tray has already been installed.
Place the shower ramp next to the tray. Depending on the size of your shower tray, the perimeter
height will vary. As you can see in this demonstration, the
shower tray we are using is thinner than the factory end of the shower ramp.
In our case, we need to cut the ramp to achieve a flush transition.
Measure the height of the shower tray. Then find the corresponding height on the
ramp. Mark the ramp at this location.
Using a utility knife, cut the ramp. Once again dry fit to ensure a flush transition.
We need to install an additional section of ramp to span the width of the shower entrance.
Measure the remaining space…and cut a section of ramp to size.
Dry fit the ramp. Now we can begin the installation.
The shower ramp is installed using any of our Schluter thin-set mortars…(PAUSE)…or
an unmodified thin-set mortar. Use a 1/4 inch x 3/8 inch square or U-notched
trowel to apply the mortar. Apply a thin layer of mortar to the subfloor,
wall, and edge of the shower tray with the flat side of the trowel to produce solid contact
with the surface… (PAUSE)…and then comb additional mortar using the notched side of
the trowel. Place the ramp into the thin-set mortar.
Install the other section of ramp in the same manner making sure that there is thin-set
mortar at all points of contact.
Place a piece of cardboard over the ramps for protection and fully embed them in the
thin-set mortar. We strongly recommend installing Schluter-DITRA,
or another Schluter uncoupling membrane, outside of the shower area. This will provide continuous
waterproofing between the “wet area” and “drying area” in curbless applications.
To seal the connections between the tray, ramp, and DITRA, we will use Schluter®-KERDI-KERECK
inside and outside corners and Schluter-KERDI-BAND waterproofing strips.
The KERDI accessories are installed using thin-set mortar. The mortar is mixed to a
fairly fluid consistency, but still able to hold a notch.
A 1/4 inch x 3/16 inch V-notched trowel or the Schluter-KERDI-TROWEL, which features
a 1/8 inch x 1/8 inch square-notched design, is used to apply the mortar.
Apply a thin layer of the mortar with the flat side of the trowel to produce solid contact
with the surface and then comb additional mortar using the notched side of the trowel.
Center the KERDI-BAND over the joint…(PAUSE)… and embed in the thin-set mortar using the
flat side of the trowel or a drywall finishing knife to ensure full coverage and remove air
pockets. Make sure that 2 inch overlaps are maintained
at all seams, including the between the two sections of the ramp.
