Brick/stone used around tub and on walls - cut Austin Stone available in Texas / Oklahoma areas. Rock is said to be okay in shower, recommended to be sealing with a good stone sealer. It's pretty porous. Buechel Stone recommends products from Prosoco http://www.prosoco.com
love this room, love the stone in the room but may just be to much weight for an elevated addition. love everything but the cowhide and longhorn horns. Seems wrong for a UT guy to say that.
