You will need some type of countertop to finish off the cabinet. Have you considered doing a pedestal sink or a laundry sink tub instead?

Thank u for reply! Trouble is we have granite on other side of laundry room and now we are putting in extra cabinets. I won’t be able to match granite. I’ll look into those sinks

Are there sinks that take up whole top of cabinet? So it’s over the counter?

No, there is no sink that will take up the whole top of the cabinet. Both under mounted and top mounted sinks will require a subtop and counter to support it on the cabinet.

I want it to look like that but prob is I am getting cabinet made to match existing cabinets

get the laundry sink first and have them build the cabinet around it

drop in, self rimming

What is the purpose for your sink? Do you have limited space and are trying to create a doggie spa area! where you need more width, rather than depth? My understanding is that a farmhouse sink that extends a bit behond the cabinets, requires additional support beyond a regular sink support

I would steer clear of those plastic/acrylic-type (? polypropylene) laundry tubs, whatever you do. They always end up looking like utter cr*p. There's just no way around it, unless you never actually use the sink. I would go with stainless or porcelain instead if aesthetics are important to you (which I get the definite sense they are).

We do have a one of those monster-size polypropylene utility tubs down in the basement, and it is really useful to have such a big utility sink in the house -- but at only 3 years it is beat up and butt-ugly, but it's strictly utilitarian and we don't see it unless we have a reason to use it.

Home Depot has lots laundry sinks with cabinet, sink, and faucet. No countertop required.
