Hi I am after a 900 x 1400 tray, is it ok to cut 100mm off the 1500 tray and if so I imagine it is taken off the end opposite the waste?
I can confirm that the wet room kits we supply are trimmable, you can cut them down to size or to avoid obstacles with a standard handsaw. We recommend to take equal bits from each side to make sure that premachined slope is preserved, for example if you want to take 100 mm from one dimension you should take 50 mm from the top and 50 mm from the bottom.
If you have any questions I will be happy to help.
