Brand: Schluter Systems
Schluter Systems is a German-engineered, globally distributed building products company with a singular focus: making tile installations succeed over the long term. In the Canadian renovation market, the name Schluter is synonymous with quality waterproofing — and the KERDI system has become the standard against which all other shower waterproofing methods are measured.
Shower waterproofing is the one renovation step where failure is invisible for years — until it isn’t. Water that penetrates behind tile can silently damage wood framing, subfloor, and structural elements for a long time before visible symptoms appear. When they do — mould, soft spots, staining — the remediation cost typically far exceeds what the original waterproofing upgrade would have cost. The Schluter KERDI system eliminates these risks when installed correctly.
KERDI is a pliable, sheet-applied polyethylene waterproofing membrane with non-woven polypropylene fleece on both sides for bonding to thin-set mortar. It is applied directly to the wall substrate (cement board or gypsum wallboard), and tile is applied directly to the KERDI surface. The membrane also functions as a vapour retarder, managing moisture transmission through the wall assembly — not just surface water. The system includes KERDI-BAND (waterproofing strip for seams and transitions), KERDI-SEAL (pipe and valve seals), and KERDI-KERECK (preformed waterproofing corners).
For a complete, integrated shower waterproofing solution, Schluter’s KERDI-SHOWER kits include a prefabricated foam shower tray with a pre-formed slope (eliminating the need for a mortar bed pre-slope), a KERDI waterproofing membrane for the walls, a shower curb, and all the waterproofing components needed for a complete installation. The KERDI-DRAIN provides a secure, watertight connection between the tray and the wall membrane. At Vanity Mart, we carry multiple KERDI shower kit sizes.
The Schluter system is endorsed by Mike Holmes — Canada’s most visible renovation quality advocate — and consistently recommended by professional tile setters across the country. A comprehensive review comparing shower waterproofing systems placed Schluter KERDI as the top overall choice for its integrated vapour management, complete system compatibility, and industry-leading warranties.
Schluter’s KERDI-LINE linear drain is designed for bonded waterproofing assemblies and enables curbless shower designs — one of the most desired features in contemporary bathroom renovation. The drain can be positioned adjacent to a wall or at intermediate positions in the shower, giving designers and homeowners significant layout flexibility.
