Choosing the Best Shower Trays for Microcement

Here’s our guide to Choosing the Best Shower Trays for Microcement by Richie from Relentless Microcement.

In this video, Richie shares his experience of the different types of shower trays on avaiable on the market and explains the best way to prepare each one for Microcement. Essential watching for anyone looking to create a Microcement wet room or shower enclosure.

Aqua4ma Wet Room System

This is the ideal system for wet rooms and shower trays, the panels and trays are completely waterproof and rigid. And the solvent weld bonds the tongue and groove edges of the panels together very well. The solvent weld can also be used to flush joins between panels & cures within 30 minutes allowing you to sand it flat.

Rigid Shower Trays

You can also microcement onto any Shower Tray that is recommended for vinyl floors or microcement. These are rigid shower trays which allow for 3-4mm of product to finished floor height. You will need to use microcement base coat or a filler to flush out the screw holes and waiting for it to cure before you apply the primer and mesh. You may also need to use High Performance Primer to bridge the join between the tray and the surrounding floor.

Tile On Shower Trays

Cement Faced with Foam Core. Brands include: WEDI BOARDS® / JACKOBOARDS® / PROWARM® BOARDS / STS® TILES BACKER BOARD

These are not recommended for use with Microcement. They rely on the rigidity of tiles to complete the system, which means they aren’t rigid enough themselves to microcement directly on to. They are also, often held in place with large washers that make the surface uneven.

If they are already installed then you will need to tile over the surface with cement boards. You will need to respect the falls in the shower tray so that the water still flows in the right direction. Once cement boards are firmly glued in place, refer to “PREP FOR CEMENT BOARDS” for next steps.
