We have a section of wall in the laundry room that is 4' wide and I was hoping to put a pantry cupboard beside the sink. Is this too narrow? Is there a standard size that a laundry room sink should be?
What are you planning on doing with the sink. I see that most utility/laundry sinks are fairly deep and plastic. At least the ones I see at the big box stores. Go online and see what the measurements are on one of those. I would think that a nice sized kitchen sink would be just fine. Something sort of deep.
Have you looked on Houzz dot com for inspiration pics?
I have seen an IKEA sink that was for laundry, and it was 24" wide. It was nicer looking than the plastic big box store utility/laundry sinks. It had an integrated wash board embossed in the front inner surface. It was stainless steel. I think this is the IKEA sink. The cabinet is separate. I don't recall seeing that cabinet at IKEA.

Kohler has a cast iron sink that is a laundry sink and I think it is 24" wide too. This is it in its very expensive stand. You can counter mount it too.
Here is an image that I found on Houzz that shows a bathroom with intigrated washer/dryer with a petite sink :)

As enduring says, you have to ask yourself what you plan on doing with the sink. Sixty years ago, the large, deep, double basin, usually cast concrete, laundry sink was needed for wringer washers. On the opposite end of the spectrum, if all you are doing is rinsing out the softener cap, then the small sink between the W & D shown above would be sufficient. Will you use the sink to give a dog a bath or do hand laundry? Then you'd need something bigger. Is the laundry located in an unfinished corner of the basement? Then the fiberglass tubs (single or double basin) are sufficient, cheap and easy to move when needed. If your laundry will be in a finished room and you want a more upscale look, then the pictures above give you some ideas.
