Schluter®-KERDI-DRAIN is a shower drain specifically designed to allow connections to 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 body 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 top 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 body is available in ABS, PVC, or stainless steel. The plastic drain bodies feature a fleece-covered bonding flange. They are available with standard 2″ (50 mm) and 3″ (75 mm) outlets and attached to the pipe using an appropriate solvent cement. The stainless steel drain bodies are available with standard 2″ (50 mm) or 3″ (75 mm) no-hub outlets or 2″ (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 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 4″ (100 mm) standard grate assembly frame features an approximately 1/8″ (3 mm) wide reveal after installation and grate/frame combinations are available in stainless steel in CLASSIC design or anodized aluminum in CONTOUR design, both available in a variety of finishes. The 4″ (100 mm) KERDI-DRAIN-STYLE grate assembly frame features a minimal reveal after installation. It is made of brushed stainless steel and can be combined with one of three grate design options: FLORAL (E), CURVE (F), or PURE (G). Various metallic and color-coated finishes are available. The 4″ (100 mm) TILE grate is a square stainless 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 6″ (150 mm) square and round stainless steel grate assembly frames feature an approximately 3/16″ (5 mm) wide reveal after installation and can be combined with stainless steel grates in CLASSIC design or a square cleanout cover. Please note that 6″ (150 mm) grate assemblies and grate assemblies used with the 5 -1/4″ (133.4 mm) adaptor kits only allow vertical and tilt adjustment (no lateral adjustment).
KERDI-DRAIN requires no special maintenance and is resistant to mold and fungi. The drain grate may be removed to clean the drain housing and the drain pipes.
Clean the grate using a neutral cleaner. Avoid the use of strong acids (e.g., hydrochloric, hydrofluoric) and bases/alkaline cleaners (e.g., bleach, ammonia, chlorides). Do not use abrasive cleaning agents and tools. Even stainless steel requires periodic cleaning, which will maintain a neat appearance and reduce the risk of corrosion. Stainless steel surfaces develop a sheen when treated with a chrome-polishing agent.
