A clean, modern replacement or upgrade sink built specifically for RV kitchens. The Better Bath LIP385313 installs as an undermount, features square corners with coved interior edges for easy cleanup, and is certified to meet IAPMO standards -- the same certification used in residential plumbing. At 27 inches wide with a 7-inch basin depth, it handles real dish loads without the cramped feel of a standard coach sink.
Most factory RV sinks are thin, shallow, and loud. Lippert built the Better Bath line to close that gap. The LIP385313 uses 20-gauge T-304 stainless steel -- thicker than the 22- or 24-gauge material common in budget coach sinks -- which reduces flex, resists denting, and deadens the hollow ring when water hits the basin.
Square corners and straight sidewalls give this sink a contemporary look that pairs well with modern RV cabinetry, while the coved interior corners (rounded at the bottom where wall meets floor) eliminate the hard-to-clean right-angle seam found on older designs. Installation is undermount, so the countertop surface runs flush to the sink opening for a seamless, easy-to-wipe finish.
Extra-thick stainless exceeds IAPMO-mandated industry standards. Resists denting, corrosion, and surface staining through years of daily RV use.
Mounts below the countertop cutout for a flush, seamless surface. No rim lip to trap crumbs or moisture against your countertop edge.
Rounded transitions where the basin walls meet the floor eliminate hard-to-reach right-angle seams, making the sink faster to clean and more hygienic on the road.
Compatible with most aftermarket drain baskets and garbage disposal flanges. No proprietary fittings required for a straightforward drain hookup.
Undermount sinks require a solid-surface, laminate, or tile countertop that can be cut and supported from below. The sink clips or adhesive-brackets to the underside of the countertop deck. Because the rim is not visible from above, your counter material and edge profile determine the finished look -- plan your countertop cutout carefully before ordering.
The 3-1/2 inch drain opening is the North American standard shared by the vast majority of kitchen drain strainers, basket assemblies, and garbage disposal flanges. Standard P-trap assemblies in 1-1/2 inch or 1-1/4 inch pipe connect normally. No adapters are typically needed for replacement installations in coaches originally equipped with a 3-1/2 inch drain.
T-304 stainless is an austenitic alloy with good resistance to rust, household chemicals, and the temperature swings that come with seasonal storage. At 20 gauge, the basin walls are stiff enough to minimize the drumming noise that thinner sinks produce. IAPMO certification (International Association of Plumbing and Mechanical Officials) confirms the sink meets or exceeds the material and construction standards required by most RV and residential plumbing codes.
