American Standard Reliant 22 in. Pedestal Sink Top Only, 4 in. Centerset Holes - AMS-467204

No. The Reliant 22 inch model 467204.02 is the china top only. The pedestal column is a separate purchase, and so is the faucet. What does come in the box is the wall-mounting hardware, since the top carries its load at the wall with the pedestal supporting the front.

Yes, an integral rear overflow is cast into the china. That means you need a lavatory pop-up or grid drain built for an overflow opening (the type with side ports in the drain body). A drain made for an overflow-less vessel basin will not vent the overflow channel.

The top ships with wall-mounting hardware, so it anchors to the wall at the back. It is still designed as a pedestal lavatory, and the column carries the front of the basin, so plan on blocking in the wall and the matching pedestal for the intended support. If you want a true wall-hung install, order a lavatory made for wall hanging with a concealed arm carrier.

The Reliant top is vitreous china with a high-gloss glaze, which is stain resistant and wipes clean, so it holds up to the cleaning chemicals used in apartment turns, hotels and light commercial restrooms. Chip resistance is the limit on any china fixture, so in high-abuse public restrooms many specs move to a wall-hung china or solid surface lavatory instead.
