Is the drain grate included?

No. The kit includes the KERDI-DRAIN flange with a 2-inch outlet, but the grate is sold separately. Choose a grate that fits the flange and your tile.

Can I use this over a wood subfloor?

Yes, Schluter rates the system for wood and concrete subfloors when installed per its instructions. The subfloor must be level and deflection must meet Schluter's limits.

Can I cut the shower tray to fit?

The tray can be trimmed at the perimeter, but only within Schluter's stated limits, and the drain opening cannot be moved. Plan the drain position before you buy.

Does it work with any drain?

No. It uses the KERDI-DRAIN flange, so the rough-in drain must match that fitting and the 2-inch outlet.

What else do I need to finish the shower?

Thinset, a trowel, the drain grate, tile and a suitable drain body below the flange. The kit covers the waterproofing, tray, curbs and seals.

Is it worth it over a PVC liner and mud bed?

It costs more in materials but saves labor and gives a bonded waterproof layer that is hard to replicate with a liner. Choose it if you want a single-source system and a faster install.

What reviewers say

Owners and installers treat the KERDI system as a proven way to build a watertight shower, and the kit is liked for bundling the parts. Complaints center on the missing grate and on the care needed to set the tray and drain correctly.

What people mention

WaterproofingPraisedInstallers say the bonded membrane and flange give a continuous watertight layer over tray and walls.
Kit contentsMixedBuyers like getting tray, curbs, membrane and seals together but note the drain grate is not in the box.
Drain placementCriticisedThe offset drain and fixed tray size force the layout to be planned before plumbing is roughed in.
Install effortMixedPreformed corners speed up the job, yet the tray needs a level, solid subfloor and careful thinset bedding.
Build qualityPraisedOwners describe the tray and board as rigid and the finished shower as solid underfoot.
