Cahaba CASS2522DISB-20.4 25 In. Standard Radius Single Bowl Drop-In Rectangle 20 Ga. Stainless Steel Kitchen Sink - 4 Prepunched

No. Mounting hardware is not included, and there is no basin rack or bottom grid in the box. For a drop-in installation you will need to supply rim clips plus silicone or plumber's putty for the bead under the rim, and the drain assembly and strainer are separate as well. Worth adding to the order so the install is not held up.

The Cahaba CASS2522DISB-20.4 is prepunched with four holes on standard 4 inch centers spacing, so a single-hole faucet leaves three openings exposed. You can cover them with a deck plate (escutcheon) sized for 4 inch centers, or put the extra holes to work with a side sprayer, soap dispenser, or air gap for a dishwasher. The holes are punched at the factory and cannot be removed, so if you want a clean single-hole deck, order a 1-hole version instead.

It is a drop-in (top-mount) sink, so the rim sits on top of the counter and covers the cutout edge. That makes it the right choice for laminate or a counter where the existing cutout edge is not finished, and it is the easy direct replacement for another top-mount sink of the same 25 x 22 inch footprint. It will not work as an undermount, and it is not reversible. If your counter is stone with a polished undermount reveal, you want an undermount bowl instead.

20 gauge stainless is the common builder and turnkey spec for apartments and rental units, and that is what the Cahaba CASS2522DISB-20.4 uses. It is thinner than the 16 or 18 gauge bowls specified for heavy commercial use, so it will flex and transmit more noise from the disposal. For a landlord replacing sinks across a fleet of units it is the standard choice; for a restaurant or high-abuse back-of-house, step up in gauge.

Drain placement is center. A centered drain sits directly over the middle of the cabinet, which usually means the tailpiece needs an offset to reach a wall trap that was set up for a rear or offset drain. If your current sink drained off-center, budget for a flexible or offset tailpiece. Centered also means no usable cabinet space is gained under the bowl, unlike a rear-set drain.

Standard radius means the inside corners of the bowl are curved rather than squared off, which is what the Cahaba CASS2522DISB-20.4 uses in its rectangular single bowl. Curved corners are easier to wipe out and do not trap debris the way a tight zero-radius corner can, which is why they get specified for rentals and MRO replacements. Zero or tight-radius bowls give a squarer, more modern look and marginally more usable bottom area, but they need more attention to keep clean.

Brushed stainless is the only finish it comes in. That satin brushed surface is the same look as a standard stainless range or dishwasher front, and it hides water spots and minor scratches far better than a mirror-polished bowl, which is why property managers standardize on it across units.

About 9 pounds. One installer can set it and bead the rim without a helper, which is one of the practical advantages of a 20 gauge drop-in over a heavy cast iron or fireclay bowl that typically needs two people and cabinet support.
