Waterproof Cabinet. All it takes is one leaky pipe to turn a shiny new sink base cabinet into a pulpy mess. That's why only the face frame and door panel of Merillat's CoreGuard Sink Base are wood - the rest of the carcase is made of a water-resistant polymer. To make spills easier to clean, the shelves feature raised ribs and a slight forward tilt. Prices for kitchen cabinets start at $930; bathroom vanities are also available.
