So I'm looking to replace my current shower tray as it has cracked. It is one of those long rectangular low profile trays as the ceiling is sloped so not too much height to work with & is in a downstairs bathroom & I believe it is a concrete base. I'm just looking for some advice as to any recommendations of what shower tray material/brand to go for/to avoid? I had wanted to go for the Mira Flight but the shower drain currently is in the middle of the base & they do not do those with one in the middle & how much more would it be if I did move the drain?
