plywood sinks .. marine wood coated with fiberglass resin
are easy to make. i miss the one i used to use ..
i currently use a long plastic sink that i wish i never bought and installed. lol
Any thoughts on what is the best cheap sink to go in a darkroom? Would I be okay with one of those big plastic utility sinks?

You don't need marine grade plywood or epoxy. I'm building my 3rd large darkroom that uses regular plywood and oil based paint for the sinks. I make my sinks out of 2x6" (1.5" x 5.5") lumber and 4x9 sheets of 1/2 nice plywood - about $40 a sheet.
I cut a notch in the 2x6 to hold the plywood bottom:

The ends are mitered - you need at least a 10" chop saw to do it but a 12" saw is better. Clamp and use 2.5" drywall screws to hold them together.

Screw the plywood into the frame using #6 screws 1.5" long. I run a bead of silicon caulk sealer in the notch to help seal it. Here's what they look like sitting on the 2x2 frame supports:

You MUST seal every seam with silicone caulk and let dry for at least 24 hours. Now use OIL based primer and paint:

I bought mine at Lowe's.
Use two coats of primer letting it cure for 24 hours in between coats. Then put on 3 coats of oil based paint, let dry 24 hours in between coats. After the last coat let it cure for 72 hours before using it.
Here are my sinks with the primer on:

I've never had any issues with my sinks as water drains over them. I do not fill them up like a wash tub. I use archival washers and the water just drains out and runs over the sink. If you want a deep sink I would use a wash tub and fiberglass the sink end to the tub and seal it.
Here's the full story on my current darkroom build.
