Cahaba CASS18UM30SB – Frequently Asked Questions

1) What size cabinet do I need for the Cahaba CASS18UM30SB undermount sink?
Plan on a 33 inch minimum base cabinet. The sink itself is 29-3/4 inches wide, so a 30 inch base will not leave room for the undermount reveal and mounting clips. Anything narrower and you need a smaller bowl.
2) Can the Cahaba CASS18UM30SB be installed under laminate countertops?
It is built as an undermount and is meant for solid surface tops such as granite, quartz, or solid wood, where the cutout edge is finished and can carry the sink. Standard laminate with a particleboard core is not a safe substrate for an undermount. If laminate is what you have, you want a topmount sink instead.
3) Does the Cahaba CASS18UM30SB come with a drain and mounting hardware, or do I need to buy those separately?
The sink ships with the drain assembly, mounting hardware, a bottom grid, and a cutout template. What you still need to supply is the faucet, the P-trap and tailpiece, plumber's putty or silicone, and the sink clips' adhesive anchors if your fabricator requires a specific type. There is no overflow drain on this sink.
4) Is the Cahaba CASS18UM30SB approved for a restaurant or commercial kitchen?
No. Cahaba states this sink is made for residential use only and should not be used in commercial applications. For a restaurant, break room in a commercial building, or anything inspected under foodservice rules, specify a sink listed for commercial duty.
5) How deep is the bowl on the Cahaba CASS18UM30SB kitchen sink?
The single rectangular bowl runs 9 inches deep, with a bowl footprint of 27.75 inches wide. That depth handles sheet pans and stockpots, but check your disposal and P-trap height under the cabinet, since a 9 inch bowl plus a disposer eats most of the space above the trap arm.
6) Where do I drill the faucet holes for the Cahaba CASS18UM30SB?
The sink has zero faucet holes drilled. Because it mounts under the counter, the faucet and any accessories (sprayer, soap dispenser, air switch) get bored through the countertop by the fabricator, not through the sink deck. Give your fabricator the faucet spec before templating.
7) Is 18 gauge stainless thick enough for a rental unit kitchen sink?
18 gauge is the common spec for residential kitchen sinks and is a step heavier than the 20 and 22 gauge sinks that dent and drum. This one is 304 series 18/10 chrome-nickel stainless with a sprayed sound deadening coat plus a rubber pad, which is what keeps the noise and condensation down in a multi-family unit. For heavy institutional traffic, look at a commercial-rated sink instead.
8) Is the drain centered on the Cahaba CASS18UM30SB single bowl sink?
Yes, the drain sits at center of the bowl. That puts the tailpiece in the middle of the cabinet, so if you want clear shelf space under the sink or you are planning a pull-out, a rear or offset drain sink is the better pick.
9) What finish is the Cahaba CASS18UM30SB and will it match my other stainless appliances?
It comes in one finish, brushed stainless, described as a commercial-grade satin. That satin brush is the standard look on stainless ranges and dishwashers, and it hides water spots and scratches far better than a mirror polish.
10) How much does the Cahaba CASS18UM30SB weigh for a one-man install?
19 lbs. Light enough to set by hand, but an undermount still wants a support rail or a helper underneath while the clips and adhesive set, since nothing holds it up until the mounting hardware is tight.
