Its here for you :
Wetdecs Tilux wetroom shower tray former
Second option is a Tuff2 wetroom former much like the Impey tray, this has a tray height of 22m and trap depth of 130mm so you would need to go deeper. The gulley seal and waterproof membrane is a diy job on this one although it is the more expensive
It is here for you :
Wetdecs Tuff2 Wetroom Shower base former
Both of these wetroom shower trays are level access and suitable for wheel chair loads
The rest of your floor won't need tanking once the base is sealed in. The walls in the wet area will need tanking and there are 2 tanking kits available.
Have a nose and we will see where we go from here
