American Standard Declyn Wall-Hung Sink Less Overflow with 4-Inch Centerset, for Concealed Arms - AMS-321975

No. The Declyn 321975 is built for concealed arms, and those arms are supplied by others. You'll need to source and set the concealed arm carrier separately, and rough it into the wall before the china goes up. Budget for that on the job, it is not in the box.

No, it is a less-overflow bowl. Nothing drains back through a secondary channel, so the drain assembly you order has to be a grid or open style without overflow ports. A standard pop-up with overflow slots will still work mechanically but the slots serve no purpose. In restroom applications where overflow protection is required by the spec, this is the wrong bowl.

No. Because it hangs on concealed arms rather than a visible bracket, the arms have to land on solid backing, either a chair carrier in the chase or steel blocking let into the studs. That has to be set before the wall is closed. If the wall is already finished with no blocking in it, you are opening it back up or switching to a pedestal or console lavatory.

Yes. A wall-hung lavatory carries no pedestal or cabinet, so the P-trap and supply stops are open to view and open to touch. Plan on a chrome or brushed trap and angle stops if appearance matters, and on ADA-type installs a trap insulation wrap or offset trap for the accessible clearance. The sink itself is supported entirely by concealed arms, which are supplied separately.

Vitreous china is the standard material for commercial lavatories. The glazed surface is non-porous, so it takes repeated cleaning with typical restroom chemicals and does not stain or absorb the way a coated metal or composite bowl can. The trade-off is that china chips if struck, so on high-abuse openings some specifiers move to stainless. For normal office, school, and multi-family restroom traffic, china is what gets specified.

White only, ordered as part number 321975.02. If you are matching existing fixtures in a building, white is the one option, so a bone or biscuit restroom will not match.

It is a molded recess in the china ledge that holds a bar of soap and drains back into the bowl, so you don't need a separate surface-mounted soap dish on the wall. In a bathroom with no vanity top, that matters, since a wall-hung lavatory gives you no counter to set anything on.
