20-1/2” ADA-Depth Oval Porcelain Top Mount Vanity Sink in White

ADA vanity sink requirements come down to three installed figures: rim or counter no higher than 34 inches (§606.3), knee clearance of at least 27 inches (§306.3), and a 30 by 48 inch clear floor space for forward approach (§305.3). This 20-1/2 by 17-1/2 inch oval top mount is built for that geometry: the shallow basin supports the forward-reach and knee-clearance dimensions on vanity cabinets 24 inches and wider, with a rear-set drain and integrated overflow. Note the 7-5/8 inch outside height: on top-mount installations the underside clearance depends on counter buildup, so the §306.3 check runs against the installed assembly, not the bowl alone.

Crafted from true vitreous china and triple-glazed for added strength, this sink features one of the industry’s most resilient finishes—mirror-like, stain-resistant, and built to last. The drop-in design allows for fast, hassle-free installation into most countertops, including laminate or wood surfaces, without the need for a polished edge.

With a rear-set drain to maximize cabinet storage, and an integrated overflow for added safety, this sink offers the convenience and performance needed in high-use bathrooms, whether residential or commercial. The recessed drain lip and carefully engineered basin slopes ensure quick drainage with no standing water.

Pre-drilled with three faucet holes to accommodate 4" centerset faucets, it’s ready for installation with standard plumbing hardware.
