Per the Lady of the House, I installed a plastic utility sink in a kitchen that's going through a extensive remodel. The remodel started when the dishwasher water line started dripping and destroyed the floor in a 20' x 15' section.
What's so great is that installing a temporary sink--a throw away, really--never occurred to me or in the many remodels I've seen. Most people will use the bathroom to wash dishes...for weeks.
Brilliant lady, she is!
