I just received some flooring samples from Rubberflooringinc and see the back, the part that rests on the shower floor, is a bunch of 1/8 inch size feet spaced about 3/8 inch apart. This makes me wonder what these feet will do to the floor. Are they so small that they'll eventually punch holes in it?
I'm being overly cautious because I don't know the strength of the floor. Has anybody had long term experience with the product?
