Cost: $5 and up per square foot, plus labor
Unglazed tile can be set over a concrete base for a classic look with enough traction for a pool deck. The installation can take time, and will drive up the project cost. A tile deck can be very attractive, but it also requires some upkeep as grout lines are liable to crack or split, and may need to be replaced.
Concrete decks will likely remain very popular, but other good options are available.
