If it was the correct size, usually they are too small and not wide
enough. My current sink is 3 foot by 10 foot and I am considering
building the next one 3 foot by 12 foot, and I still may build two (one
for film, one for Pt/Pd). (Sometimes a custom size might be needed to
fit a particular space.) I use every square inch of my sink space. I
need the room to keep the work flow easy.

At one time I had a darkroom without any sink or running water. I put
things in a tray or bucket which was carried to the kitchen to empty and
refill or treat and dispose. I had plastic under the trays and was
careful to not spill anything. After that, I advanced to a bathtub in
the second of two bathrooms. I never could put in the effort of setting
up and taking down with only one bathroom, although I know those who
do. I have known some to use an ingenious space saving array of
vertically stacked trays. However my preference is to enjoy the wide
open dark spaces of unrestricted movement and the ease and efficiency of
a naturally flowing processing space. This can vary for each, but
usually requires a custom sink.

And to clarify some concerns. Any joints or seams are a potential
problem. And one must keep in mind that the sink is not exposed to just
water (or rain). Some of these chemicals can be persistent over time.
Sometimes strong acids or concentrated solutions inadvertently spill or
splash and may not get totally cleaned out of a joint, crack, or
crevasse. And, it is unlikely that the plastic grid supporting the
trays is removed for a cleaning. A continuos smooth surface seems the
best way to go with the only point of concern being the attachment to
the drain. I have come to a time of not wishing to fix or repair my
sink every year (sometimes less). Even the best dado joint with marine
glue, epoxy paint, and silicone caulk needs attention. Bring on the
durable, continuous plastic liner (be it PVC, acrylic, fiberglass, or
whatever will last).
