: I am replacing a shower floor. The previous floor was concrete and had a liner below the floor. This liner was leaking (after 25 years) and I have to replace the liner before pouring new concrete. Do you have any suggestions as to the layout of the new liner? The old liner was installed incorrectly (in my opinion). They had cut the corners to the ground level, eliminating the effectiveness of the liner at every corner.

: Thank you,
