Depth Markers for Swimming Pools

Swimming Pool depth markers identify the water depth around the pool for swimmers. State codes require public pools to be plainly marked at the waterline and/or on the pool deck with depth markers. Additionally, depth markers on the deck are required to be anti-slip. The height of the numbers on the marker are usually required to be at least 4 inches, depending on your state. Depth markers are available in ceramic tile, stick-on 3M, stick-on plastic or stencils. Tile depth markers are available in skid resistant for pool decks and smooth for pool walls and water lines.

These pool safety tiles should be placed at least to mark the minimum depth and maximum depth. They should be placed on both sides and at each end of the pool and between the shallow and deep end.
