OneWay Showerlay Technical Drawing

Our OneWay wet room kits are available in two thicknesses: 30mm and 40mm. Depending on space, floor type, and desired gradient you can choose best option for you.

If you have timber floor - existing floor board thickness. Usually they are 30mm thick, in that case you should go for adequate thick wet room kit, to avoid floor height increase and step ups. If you want to achieve stepped up floor, 40 mm thickness might also be a good choice. Wet room kit timber floor fitting instructions

In case of concrete floor, every thickness is suitable, if you're going to screed the floor you need to shutter the future shower area off and leave proper space for tray to be inserted in the future. If screed has already been done, you will need to use jackhammer or similar tool to groove exact tray thickness and shape when the shower is going to be created. Wet room kit concrete floor fitting instructions

In case of both floor types, every shower tray thickness is enough to bear human weight, as it needs to be underboarded beneath entire surface either with ply or solid concrete. The biggest difference between thicknesses is the slope's angle achieved after installation is completed and shower tray tiled.
