finished it, very annoying job, panel so flimsy. cut panel to the right size, then found it wasnt high enough (because bath was raised a little with wood supports. got an L shape plastic trim from b n q to cover the gap at the bottom. had to make recesses bigger in 3 pieces of wood drilled to floor tiles to raise the bath panel. screwed panel to 3 bits of wood, fitted L shape trim, held down by the wood after loosening screws to let the trim under the wood then securing back down. then used double sided foam tape (originally bought for the L- shape trim, to attach the top of the panel to the wood strip that runs along the top edge, because it was so flimsy it wouldnt stay up where it should.
