My husband and I recently built an outdoor pool house. We have veneered plywood cabinets with stone from the NC mountain quarries. I want to install granite counter tops, because they not only would look the best, but would be very serviceable. The cost of $50 sq. ft. installed is proving to be a little prohibitive; do you have any suggestions for another counter top that would be less costly, yet very substantial? Someone else suggested concrete…?
