This looks great, I'm looking to have a 1200 x 2300mm walk in shower with a 1200 returning screen. This would be perfect (I think) I don't know what height I need though the intent was to use a 18 or 22 mm structural backing board and wanted this to site at the same height. Is this possible?
Thank you for being interested in our products. 1200 x 1200 would be fine shower tray for 1200 x 2300 mm wet room enclosed by a shower screen.
According to our fitting instructions, we recommend to remove floor boards, fix battens to the joints and mount at least 18 mm thick marine plywood in between the joints so the ply and joints are on the same level. Then you can fit the tray on top of that prepared supports.
In such case your tray just replace the floor board. If you want to use 18 mm thick backer boards on the remaining floor area I would recommend to go for 35 mm thick tray.
