Concrete bathrooms or concrete for shower walls is a hot trend.
We do concrete finishes for shower walls over HardieBacker cement board treated with water-proofing elastomeric membrane to prevent water from escaping the shower area. Cement application is done in 3 coats 1/4" thick. The finish is protected with 3 coats of  water-proofing matte sealer. Talk to us about your concrete shower ideas.
