I am in the process of having my pool built and have a question regarding tile on a bench. The pool is rectangular, 40ft X15ft. The pool has a bench along one of the sides that is 40 feet long. I wanted to have the bench tiled with 6 inch by 6 inch tile. However my pool builder told me that I cant' have 6 inch tile on the bench because it would make it too slippery. He is recommending that I go with 1 inch by 1 inch tile instead. I prefer the larger tile because of the look. Any comments on installing tile on benches? Do you think that it would indeed make it too slippery?
