What are the dimensions of the cutout for drain on the Showerlay Wiper 800 x 1500 mm Line Pure?
800 x 1500 shower tray can be trimmed to a minimum size of 640 x 1300 mm.
There's a recommendation though - it would be the best if you could cut equal bits from each side to make sure to keep premachined slope. For example, if you want to shorten 1500 dimension to 1400 it would be the best if you took 50 mm from the top and 50 mm from the bottom of the shower tray.
If you have any questions I will be happy to help.
