I used a darkroom sink made like this in a professional's studio for years and it was outstanding.
It was wide like this and six feet or so, on a wooden stand with a shelve below and an angled shelve on one end, with sides and top end barrier for a washing tray.
Epoxy paint works great and I hope some takes this one and with a little effort, makes it a great standalone sink, in a darkroom space with running water.
It'll be great for years and, if I had such a space, instead of a small, dry bedroom and my fairly small ABS darkroom SINK, with a deep well.
About the only thing better, IMO, might be a Stainless Steel sink of the same dimensions, but those are noisey and no as nice to lean against as a wooden sink is, especially for hours long printing and film development.
IMO, someone can really make this a great sink, in a bathroom or any other darkroom space, tweaks or no.
