CahabaCASS3018UMSB 30 In. Standard Radius Single Bowl Undermount 16 Ga. Rectangle Stainless Steel Kitchen Sink

You need a 33 inch minimum base cabinet. The sink itself measures 30 inches long by 18-1/2 inches wide overall, so a standard 30 inch sink base will not take it. If you are stuck with a 30 inch cabinet, step down to a smaller bowl.

No on both counts. Mounting hardware is not included and no basin rack ships with it, so budget for undermount clips and epoxy or a sink harness, plus a bottom grid if you want one. The drain is not included either in the listed contents, so plan on a strainer as well.

No. The Cahaba CASS3018UMSB is built as an undermount only, with no deck or rim to rest on the countertop and no faucet holes drilled. It needs a solid-surface counter (granite, quartz, or similar) with a cut and polished opening, and the faucet mounts through the counter or the wall. For a laminate top you need a drop-in sink instead.

The bowl is 9 inches deep, which is also the overall height of the sink. Interior bowl footprint is 28 inches long by 16-1/8 inches wide at the base area, tapering out to 30 by 18-1/8 at the top. That depth handles sheet pans and stock pots but leaves less room under the cabinet for a disposal and P-trap, so check your drain height before you set it.

16 gauge is the heavier end of residential stainless and it is what holds up in high-turnover units. Thicker steel dents less under dropped cookware and rings quieter than the 18 and 20 gauge bowls typically found in builder-grade kitchens. The Cahaba CASS3018UMSB weighs 24 pounds, which is the weight you would expect from a bowl at that thickness.

Drain placement is center. That puts the tailpiece in the middle of the 30 inch bowl rather than offset to the rear, so if your existing wall stub-out was set for a rear-drain bowl you will be building an offset in the trap arm. Center drains also eat more of the usable cabinet floor than a rear drain, which matters if you are fitting a pull-out waste bin underneath.

Standard radius means the corners of the bowl are curved rather than squared off. Curved corners are easier to wipe out and less prone to trapping grime in the corner seam, which is why property managers often prefer them. Zero radius bowls give a sharper, more commercial look and slightly more usable bowl volume, but the tight corners need more attention when cleaning. This one is a rectangle bowl with the softer standard radius corners.

Single bowl, 30 inches of uninterrupted basin. That is the choice when you wash large pans or roasting trays and do not want a divider in the way. A double bowl of the same width gives you two smaller compartments for separating dishwater from rinse, but neither compartment will take a full sheet pan flat. The Cahaba CASS3018UMSB is the single bowl configuration, brushed stainless finish.
