Ikea has a stainless steel sink and I believe it goes into a 24 inch deep cabinet. If I remember correctly the front wall of the sink has a washboard feature. This downloaded image I found on the internet looks like it is taken at an Ikea store display. The online price is $169 I think.

Thank you! I didn't think to check Ikea.

yes there's a washboard along the front inner surface

also i think new ones have an overflow along the back:

These drop into a 24"w kitchen cabinet (Ikea or otherwise), and the stainless-steel edge lines up with a square-cut countertop on adjacent cabinets. Very nice.

Another option: use a 10" or so deep kitchen sink in a kitchen countertop - I'm doing that with an undermount D-shaped 10"d sink (which added to the countertop thickness, yielding an 11-1/2" deep sink), utilizing a solid-surface countertop removed from someone else's kitchen remodel. It will also cover the washer and dryer.
