Our take on the Schluter KERDI SHOWER KIT Complete kit

The Schluter KERDI Shower Kit is a complete waterproofing system for a tiled shower: a sloped shower tray, two curb pieces, KERDI membrane and band, preformed corners, pipe and mixing valve seals, and a KERDI-DRAIN with a 4-inch stainless steel grate and integrated bonding flange. It is built for vapor-tight assemblies, so it suits steam showers as well as standard tiled showers. The value is in buying the pieces as one matched set instead of sourcing tray, drain, membrane and seals separately. It is a pro-grade system: the tray sets the drain position and slope, so the layout has to match the tray size you choose.

Pros
  • One set covers tray, curbs, drain, membrane, band, corners and seals
  • Vapor-tight and waterproof, rated for residential steam showers
  • KERDI-DRAIN has an integrated bonding flange and stainless steel grate
  • Preformed corners and seals cut the number of hand-cut waterproofing details
  • Multiple tray sizes to match the shower footprint
Cons
  • Tray size and drain placement must match your rough-in; no adjusting after install
  • Requires Schluter-compatible thin-set and careful membrane laps to keep the warranty
  • Not a beginner project: sloping, drain bonding and banding take skill
  • Kit contents vary by size, and the 48 x 48 ABS kit omits the KERDI collar

What reviewers say

Owners and installers treat the KERDI shower system as a proven, code-friendly way to waterproof a tiled shower, and the all-in-one kit is valued for saving trips to gather parts. Complaints center on the fixed tray geometry and the fussy thin-set and banding steps.

What people mention
  • WaterproofingPraisedOwners report the membrane and band system keeps showers dry and vapor-tight.
  • CompletenessPraisedBuyers like getting tray, drain, corners and seals in one box.
  • Tray fitCriticisedThe tray fixes drain position and slope, so a mismatch with the rough-in is a problem.
  • InstallationMixedExperienced tilers find the steps logical; beginners find the thin-set and lapping work hard.
  • DrainPraisedThe KERDI-DRAIN with stainless grate and bonding flange is well regarded.

About the Schluter KERDI SHOWER KIT Complete kit

The Schluter KERDI-SHOWER-KIT is a complete set of the parts needed to assemble a waterproof tiled shower. It is designed to form a vapor-tight, waterproof enclosure for residential steam showers and tiled showers.

The shower tray is a KERDI-SHOWER prefabricated substrate made of high-compressive-strength expanded polystyrene (EPS) foam. It is lightweight and sturdy, and it provides a foundation for the KERDI waterproofing membrane and tile. The shower curbs are made of KERDI-BOARD, a lightweight tile substrate that works with the Schluter Shower System.

Installation takes only a few hours before tile can be set, and it is less time-consuming and labor-intensive than traditional methods. After tile installation and grouting, the assembly supports the loads common in tiled showers, including glass block walls and glass doors.

Questions and answers

Is this kit suitable for a steam shower?
Yes. Schluter rates the assembly as vapor-tight and waterproof for residential steam showers as well as regular tiled showers.
What is included in the kit?
A KERDI-SHOWER tray, two KERDI-BOARD-SC curbs, a KERDI membrane roll, KERDI-BAND strip, KERDI-DRAIN flange with 2-inch outlet and 4-inch stainless grate, inside and outside corners, a 3/4-inch pipe seal, a 4-1/2-inch mixing valve seal and a KERDI collar. The 48 x 48 ABS kit leaves out the collar.
Can I use it over a concrete floor?
Yes, the tray and drain flange are designed to bond to a properly prepared substrate with Schluter-approved thin-set. Follow the installation guide for your substrate.
Does the drain fit standard plumbing?
The included KERDI-DRAIN has a 2-inch outlet and an integrated bonding flange, which matches common shower drain rough-ins.
Do I need special thin-set?
