American Standard Ovalyn Large Under Counter Sink - AMS-497221

It mounts under the counter. The rim is unglazed because it sits hidden beneath the stone or solid surface deck, so plan on a countertop fabricated with a finished, polished sink cutout. If you need a drop-in bowl with a finished visible rim, this is the wrong version.

A mounting kit and a cutout template ship with the sink, so the installer has the clips and the pattern for the fabricator in the same box. What is not included is the faucet and drain assembly, since the faucet mounts in the countertop on an undermount installation, not in the bowl.

Yes, a front overflow is built into the bowl. That means you pair it with an overflow-type lavatory drain (one with the side port open), not a grid drain intended for overflow-less vessel bowls. Using the wrong drain will block the overflow path.

Two colors: White (model 497221.02) and Linen (model 497221.222). Both are the same vitreous china bowl, so you can match Linen fixtures in an older washroom or stay with standard White across a building.

Undermount bowls need a countertop material that can take a finished, sealed edge at the cutout, so granite, quartz, marble or solid surface. A standard particleboard laminate top exposes raw core at the cutout and will swell, so specify a drop-in or self-rimming lavatory for laminate decks instead.

Order by the suffix on the model number. The .02 suffix is White and the .222 suffix is Linen; American Standard uses the same suffix convention across its fixture line, so matching the toilet or the adjacent lavatory suffix keeps the bowls consistent.

Vitreous china is the standard material for commercial lavatory bowls: a fired ceramic with a glazed, non-porous surface that cleans with ordinary washroom chemicals and does not scratch or stain the way acrylic does. For high-abuse or vandal-prone restrooms, stainless steel is the usual alternative, but for offices, hotels, schools and multi-family units china is the normal spec.
