Cahaba CA425T18-W – Frequently Asked Questions
1) Can the Cahaba CA425T18 trough sink be drop-in mounted, or does it have to go under the counter?
Undermount only. The CA425T18 is built to install beneath a solid surface countertop, and the rim is left unglazed because it sits hidden under the deck. Dropping it into a cutout from above would leave that raw rim exposed. Plan on a solid surface, stone, or quartz top that can carry a sink cutout and support the sink from below.
2) What size vanity cabinet do I need for the Cahaba 21 inch trough sink?
Go with a 24 inch cabinet as the minimum. The sink itself is 21 inches wide by 13-3/8 inches front to back and 7 inches tall overall, so a 24 inch base gives you the side clearance for the countertop cutout and the reveal. Anything narrower will not take it.
3) Does the Cahaba CA425T18 sink come with a drain and faucet?
Neither one is in the box. You will need to order a pop-up drain assembly and the faucet separately. Because there are no faucet holes drilled in the sink, the faucet has to be a wall mount or a deck mount drilled into the countertop, so decide that before the top is fabricated.
4) Does this Cahaba undermount sink have an overflow?
Yes, a front overflow is built in, with the overflow opening 4 inches up. That means the drain you buy has to be an overflow-type pop-up with the side port open, not a grid drain or a non-overflow assembly. Fit the wrong one and the overflow channel will not vent or drain.
5) What is the Cahaba CA425T18 made of, and how does it hold up in a rental or multi-family unit?
Vitreous china with a glazed porcelain finish. The glaze is a smooth, chip-resistant surface that cleans with ordinary bathroom cleaner and will not stain the way a cultured marble integral bowl does over time. For property managers standardizing across units, china is the usual choice for durability under tenant use, and the rectangular trough shape reads as a solid-surface integral basin once it is mounted under the top.
6) How heavy is the Cahaba 21 inch trough sink, and does it need extra support under the counter?
20 pounds dry, plus water weight once it is filled (the bowl holds 3.6 gallons). That is light enough for standard undermount clips and silicone on a stone or solid surface top, but on a long trough the full-length rim needs to be fully bedded and clipped along both sides rather than at the corners only. A fabricator setting it should support it while the adhesive cures.
7) What color is the Cahaba CA425T18 trough sink?
It ships in one finish, white. The manufacturer part number for the white unit is CA425T18-W. If you are matching it to a toilet or tub in an existing bathroom, white china from different makers can vary slightly in tone, so compare against the fixture you already have rather than assuming a match.
