We just finished a total bathroom remodel after using this dingy dated bathroom. It's hard to tell from the before pictures, but it was bad...very bad. The fiberglass tub was cracked around the base, so it squeaked constantly when we were using it, and the issues that those type of surround have with mold were all true in our case (mold gets up behind the seams). I really wanted to use marble and other natural stone, but then I was worried about durability so we ended up finding some awesome deals on porcelain and Silestone, and I'm so so so happy with how it turned out.
