When it comes to installing a wet room or walk in shower the easiest way to achieve the required fall to the drain is with the use of a wet room tray / floor former. Wet room trays come with the required fall to drain (approx. 2%) built into the tray, taking away the guess work and effort of trying to create it for yourself.
As the popularity of wet rooms has increased, so has the choice of wet room trays available. Whilst this increased choice is a welcome, it does lead to confusion for some when choosing the most suitable tray for the project’s requirements and installation constraints.
Several factors need to be considered, including but not limited to:
Floor substrate – Usually wood or concrete/screed
Finished floor covering – Tiles or Vinyl
User’s needs – Is wheelchair showering a requirement?
Drain position – Avoidance of joists and aesthetics
Whilst most wet room trays / floor formers available are suitable for use in both wooden and concrete floors, and are available in many size and drain location configurations, the main deciding factors on the choice of tray will come down to the finished floor covering, and the end user’s needs, i.e. does it need to support a user in a wheelchair, and thus ‘point loading’ ability is a major consideration (more on this a little later).
