Our diatomite sink tray requires a flat space of 23.6 inches x 3.9 inches behind the faucet to fit perfectly. It is not compatible with raised edges, soap dispensers, or built-in sink accessories in that area. This stone faucet pad is designed to catch dripping and splashing water, keeping your sinkware clean and the countertop spotless - an easy upgrade for any kitchen sink. Diatomite stone can quickly absorb spilled water and dry quickly, helping to keep the kitchen countertop and sink area clean. It can be used as a draining pad, a draining stone, or a quick-dry stone pad for daily dishwashing and handwashing - reducing the number of wipes and water stains.
