My shower/tub has a window and an ugly tile suround that I would like to cover up. I am getting ready to have the house sided so it would be a great time to cover the window on the exterior. So how many people have used frp paneling and what is your opinion of it. I'd like to use the paneling to laminate over the existing tile and cover up the window. How does that sound? is there any flaws in my plan or pointers you could give. any advice is welcome thanks.
