The position of the drain exit is determined by the installer on site as the drain is cut into the trough by the user and thus can avoid joists or support beams.
The base of the tray is totally flat and is installed onto the wooden joists in the normal manner with support between the joists. It has fully adjustable drain and grid to accommodate various tile heights

It can be installed by any competent DIY person and as the drain trough is already installed into the tray cuts down on install time.

If you have a concrete floor or if there is no access under the flooring to locate the shower drain, then the tray can still be used by using a separate raised substrate. For full fitting instructions please see: Fitting the WetBase Wet Room Tray

Please Note: Shower Screen Delivery

Whilst the shower screen is delivered free of charge, it is excluded from the next working day delivery, and will follow the WetBase, drain and tanking kit approximately 2 - 3 working days later.
This is because we have to use specialist carriers due to the weight and fragile nature of the glass shower screen.

Please ensure that you have both access to your property and room of installation for the shower screen prior to ordering.

Please refer to our terms and conditions for full details of carriage etc.

The contents are all INSIDE the bucket and the contents are protected in the bucket with polystyrene infill's to stop transit damage.The instructions are printed on the rear of the tanking kit.

The followings are the instructions for installing the Wetrooms Online WetBase (standard) on a wodden floor. These instructions and others for concrete floors and the Linear WetBase can be printed and / or downloaded in PDF format here:

Linear WetBase Installation (Wooden Floor)

Wetrooms online WETBASE low profile shower trays are designed to create a flat walk in shower area without raised steps or platforms. This tray is designed to be inset into or on top of WOODEN floors and then tiled over.
The Coated shower tray is pre machined with the correct falls in all directions to the drain which is partly attached to the tray.
It requires additional support which is achieved by fitting plywood panels between the joists.

Conventional floor boards are approx 20mm thick so laying the tray on top of the joists would bring the top of the tray level with the floor boards.
WE DO NOT recommend tiling straight on to floor boards. We recommend that the entire wooden floor is covered in a 10mm thermal tile backer board prior to tiling and therefore you may need to insert a 10mm packer under the wetbase
