Schluter®-KERDI-DRAIN is a floor drain specifically designed to allow connections to Schluter-KERDI or other load bearing bonded waterproof membranes. The membrane is adhered to the large integrated bonding flange to form a waterproof connection at the top of the drain assembly. KERDI-DRAIN consists of a drain casing and fully adjustable grate assembly or covering support to which tile is applied. The grate assembly accommodates a wide range of tile thicknesses and allows lateral and tilt adjustment as well. The covering support is placed flush with the tip of the bonding flange and can therefore accommodate any thickness tile covering.
The standard KERDI-DRAIN is attached directly to the waste line. The drain casing is available in ABS, PVC, or stainless steel The plastic drain casings feature a fleece-covered bonding flange. They are available with standard 2ʺ (50 mm) and 3ʺ (75 mm) outlets and attached to the pipe using an appropriate solvent cement. The stainless steel drain casings are available with standard 2ʺ (50 mm) and 3ʺ (75 mm) no-hub outlets and 2ʺ (50 mm) threaded outlet. The no-hub outlets are attached to the pipe using an appropriate mechanical (e.g., flexible or no-hub) coupling. The threaded outlets are attached to the pipe using thread sealing compound or tape. The simple connection to standard drain outlets makes KERDI-DRAIN suitable for new construction and renovation.
The KERDI-DRAIN adaptor kit is designed to convert clamping ring drains by equipping them with an integrated bonding flang. The adaptor kit includes a stainless steel adapter ring with an over-molded rubber gasket and a variety of perforated hole patterns that align with most common clamping ring shower drains. The adaptor ring replaces the clamping ring and is attached to the drain body using the clamping ring bolts. This connection is made watertight via the rubber gasket and Schluter-KERDI-FIX adhesive/sealant. The integrated bonding flange slides into the adaptor ring, with the over-molded rubber gasket ensuring a watertight seal. KERDI-DRAIN adaptor kits, available in 5-1/4ʺ (133 mm) and 7-1/2" (191 mm) diameter sizes, are used to convert traditional clamping ring drains to integrated bonding flange drains when removal of the clamping ring drain is not practical (e.g., when they are set in concrete slabs). Adaptor kits are suitable for both mortar beds and KERDI-SHOWER-T/-TS/-TT shower tray applications.
The KERDI-DRAIN grate assembly consists of a frame, which can be seamlessly adjusted to the thickness and layout of the ceramic tile or stone covering via the height adjustment collar and lateral adjustment ring, and grates or cleanout covers that are placed within the frame. The 4ʺ (100 mm) standard grate assembly frame features an approximately 1/8ʺ (3 mm) wide reveal after installation and grate/frame combinations are available in stainless steel with plain, chrome, nickel, classic gold, vintage gold, rose gold, or oil-rubbed bronze finish and anodized aluminum with brushed nickel, brushed copper, or brushed brass finish. The 4ʺ (100 mm) style grate assembly frame features a minimal reveal after installation and can be combined with one of three grate options: Floral (E), Curve (F), or Pure (G). The style grates are available in brushed stainless steel with plain, nickel, classic gold, vintage gold, or rose gold finishes and a range of textured powder-coated finishes including stone grey, cream, greige, bronze, matte black and matte white. The 4ʺ (100 mm) covering support is a square steel plate with KERDI laminated on the surface to allow for bonding of ceramic or stone tile, which creates a virtually invisible drainage line. The 6ʺ (150 mm) square and round stainless steel grates assembly frames feature an approximately 3/16ʺ (5 mm) wide reveal after installation and can be combined with stainless steel grates or cleanout covers. Please note that grate assemblies included with the plastic KERDI-DRAIN featuring 3ʺ (75 mm) outlets and the residential adaptor kits only allow vertical and tilt adjustment (no lateral adjustment).
