FlexStone Bath Kits are lightweight, easy to install tub and shower surrounds that look just like real stone. When you see FlexStone, you'll think it's real granite or marble, because the imagery is that good...but it's actually a composite that weighs less than 1 lb per square foot. Additionally, FlexStone is non-porous, resists mold and mildew, and is easy to clean. If you're looking for video tutorials on FlexStone installation, this is your place. If you've not yet purchased FlexStone, it is sold at several retailers including Menards home centers in the midwest (or visit menards.com).
