Cahaba CA425V17 Undermount 19-1/4 in. Glazed Porcelain Oval Bathroom Sink

No. The CA425V17 is the china bowl only. The pop-up drain assembly and the faucet are both separate purchases, so order a drain and a trap along with it if you want the job to finish in one trip.

On the countertop or the wall, not on the sink. The CA425V17 has zero faucet holes, so the deck holes get drilled in the solid surface top. That means you pick the faucet spread (single hole, centerset, widespread, or wall mount) at the countertop fabrication stage, not from the bowl.

No. This sink has to go under a solid surface top, granite, quartz, marble, or a similar slab material that can take a polished sink cutout and carry the bowl on clips or a rail. Laminate with a particleboard core leaves a raw exposed edge at the opening and is not a valid mount for it. The rim is unglazed because it is meant to be hidden under the slab.

Minimum 24 inch cabinet. The bowl itself measures 19-1/4 inches wide by 15-3/4 inches front to back and stands 8 inches tall, so a 24 inch base leaves enough deck on either side for the mounting clips and the slab overhang. Anything narrower will not give you the cutout clearance.

Yes, it has a front overflow. That matters for two reasons: you need a drain with matching overflow ports (a grid drain without them will not vent the overflow channel), and it is the detail most commonly required where an unattended lavatory is a concern in rental and multi-family units.

Rear. The drain sits toward the back of the oval bowl, which usually gives you more usable room in the vanity under the front of the cabinet and shifts the P-trap closer to the wall stub-out. Worth checking against your rough-in before the top is templated.

Undermount only. It is fired with an unglazed rim intended to be concealed by the countertop, so setting it on top of a deck would leave raw, unfinished china showing at the edge. If you need a drop-in or a vessel bowl for that opening, this is the wrong body style.

It depends on your template, not on the old sink's brand. The CA425V17 body measures 19-1/4 inches by 15-3/4 inches with an 8 inch overall height, so the existing cutout has to sit inside that footprint with enough bearing surface left around it for the clips. Cahaba publishes a DXF drawing and a spec sheet for this model, and a fabricator can lay that against your current opening before anyone pulls the old bowl.

Vitreous china is the standard commercial lavatory material for exactly that reason. The CA425V17 is fired china with a glazed, chip-resistant surface, and the inner basin is curved rather than squared so water does not pool in the corners and leave mineral rings. It cleans with ordinary bathroom product and does not scratch or stain the way an acrylic or composite bowl will over a few hundred cycles a week.

15 pounds. That is light enough for one installer to hold up into the cutout while the clips go on, though a support cradle or a scrap of lumber across the cabinet makes it easier to hold level while the adhesive sets. It is well under what a stone top needs to carry.
