Just get another surround. You will never get sheets to waterproof the area.

If you can't modify something made for the space, what makes you think you can fabricate something that's not?The surrounds I have looked at are either to big or to small and I'm afraid to cut them afraid of messing up the edge that seals. I have seen them use some solid sheet of something on bathroom renovations but never can quite catch the name of it. Very simple, which is what I need. Thank you for your reply.
