Re: Replacing tub/shower walls
I would recommend going with a cultured stone product. Cultured stone comes in many colors and styles, a granite look among them. This will give you the best performing shower surround.
"Formica" like products do not look too great because they are trimmed in metal. All this trim creates opportunities for water to get behind the material and cause damage to the walls. The lifespan of this type of material isn't all that great either, maybe about 10 years in optimal conditions, so it's money poorly spent, IMHO. If you're still interested in this material, research 'Pionite' and 'Marlite'.
