Schluter[tm]-Systems now offers the Schluter-Kerdi-Shower-ST, a prefab-ricated, pre-sloped shower tray, which can be used when job conditions require the setting of the Schluter-Kerdi-Drain by the plumber prior to installation of the Schluter-Kerdi-Shower-ST.
The tray's new detachable center section can be removed and placed below the bonding flange to dry fit the Kerdi-Drain to the appropriate height. To install the Kerdi-Shower-ST when the drain has already been installed, apply sufficient thin-set mortar to the top and bottom of the detached center section before sliding it into place below the drain, to ensure solid and uniform support of the bonding flange.
