Merillat. Preventing under-sink leaks from causing stains and other permanent damage, the maker introduces its CoreGuard sink base cabinet. Except for the face, frame, and door assembly, all of the wood and wood-based materials typically used in cabinet construction have been replaced with an engineered polymer that does not absorb moisture. The cabinet’s floor tilts forward so leaks and spills migrate to the front. A rib design on the floor keeps items stored in the cabinet raised to avoid moisture damage. 517.263.0771.
