Our take on the Schluter Kerdi Waterproofing Corner 2-Pack

These are preformed inside corner seals cut from Schluter's KERDI waterproofing membrane. They bond into the membrane at inside corners of showers, tub surrounds and other wet areas to keep the waterproof layer continuous. The 4-mil sheet keeps build-up low so tile sits flat through the corner. They suit DIY and pro tile setters already using a KERDI, KERDI-BOARD, DITRA or DITRA-HEAT assembly; the corners only work as part of that system, not as a standalone seal.

Best forShower inside cornersTub surrounds and wet zonesInstallers already using KERDI or DITRAKeeping tile flat in tight corners
Pros
  • Preformed, so no folding or cutting membrane at the corner
  • Thin 4-mil sheet limits build-up under tile
  • Fits KERDI, KERDI-BOARD, DITRA and DITRA-HEAT assemblies
  • Seals the corner with the same membrane as the field
  • Backed by a 10-year limited warranty when installed to Schluter's handbook
Cons
  • Only covers inside corners; outside corners and pipe seals are separate pieces
  • Requires Schluter's thin-set and membrane technique to bond properly
  • Two per pack, so larger showers need several packs
  • No adhesive backing; needs fresh thin-set to set

About the Schluter Kerdi Waterproofing Corner 2-Pack

These preformed inside corner seals are made from KERDI membrane. They create a watertight seal at inside corners in tiled wet areas, such as showers, tub surrounds and other wet zones.

The seamless design minimizes build-up in the corner. The 4-mil thickness allows a sleek finish in tight corners. Each corner forms a continuous waterproof seam in tiled installations.

They are compatible with KERDI-BOARD, KERDI, DITRA and DITRA-HEAT assemblies. The 10-year limited warranty applies when installed per the Schluter Installation Handbook and Technical Data Sheet.

Questions and answers

Do these work with DITRA-HEAT?
Yes. Schluter lists them for KERDI, KERDI-BOARD, DITRA and DITRA-HEAT assemblies. They keep the waterproof layer continuous where two membrane surfaces meet at an inside corner.
How are they installed?
They are embedded in thin-set over the membrane at the corner, overlapping the field membrane, then smoothed flat. Follow the Schluter Installation Handbook and Technical Data Sheet for the warranty to apply.
Do I need outside corners too?
Yes, if your layout has outside corners. This pack is inside corners only. Schluter sells matching outside corners and other KERDI seals separately.
How many corners come in a pack?
Two inside corner seals. Count your inside corners before ordering; a standard shower often has several.
Will they cause a bump under the tile?
The membrane is 4 mil thick, so overlap build-up is minimal. Keep overlaps tight and thin-set even to keep the corner flat.
What is the warranty?
A 10-year limited warranty, provided the corners are installed per Schluter's Installation Handbook and Technical Data Sheet.
