American Standard Studio Carre Drop-In Sink With Center Hole Only - AMS-642001

American Standard supplies a cutout template with the sink, so you can mark the counter directly rather than working from a dimension. For planning the slab or vanity top, the sink is nominally 16-3/8 in x 16-3/8 in (415 mm x 415 mm) overall as a self-rimming square unit, so the rim sits on the deck around a smaller opening. Bowl footprint inside is 12-1/2 in wide by 9-3/8 in front to back.

Not reliably. The Studio Carre is a square self-rimming unit at 16-3/8 in x 16-3/8 in nominal, so its rim footprint is square while a typical round lavatory cutout is circular. Replacing round with square usually means enlarging the opening to the supplied template and confirming you still have rim coverage at the corners and enough deck behind the bowl for the single center faucet hole.

Bowl depth is 4-3/4 in, with a 12-1/2 in wide by 9-3/8 in front-to-back rectangular curved bowl. That is a compact lavatory bowl suited to powder rooms, hotel guest baths, and tight multi-family vanities, not a utility or deep hand-wash basin. If you need more volume for a high-traffic public restroom, look at a deeper lavatory.

It is self-rimming. The square china rim carries the sink on the countertop, so it drops into the cutout and seals to the deck with sealant, no undermount clips or rails required. That makes it a straightforward swap into an existing laminate, solid surface, or stone top where the opening matches the supplied template.

The overflow is at the rear of the bowl, integral to the china. Pair it with a lavatory pop-up or grid drain suited to an overflow basin, and note that the drain assembly and faucet are separate purchases. Rear placement keeps the overflow channel behind the bowl, which matters when you are fitting the trap and tailpiece in a shallow vanity.

Yes, as long as that faucet is single-hole. Because the 642001 is drilled center hole only, every unit takes the same one-hole faucet body, which simplifies spec and spare-parts stocking across a fleet of units. The sink ships in white only, so finish consistency is not a variable either. Faucets and drains are ordered separately.

Vitreous china, and white is the finish offered (part number 642001.02). Vitreous china is a glazed, non-porous surface that stands up to standard restroom cleaners, which is why it is the default for multi-family and hospitality lavatory specs.
