Need to replace my old leaky concrete utility sink. Currently I have a utility sink that is 48" x 20" double basin. I'm looking to replace it with a free standing plasitc sink, however everything at the hardware store is roughly 24" x 24" single or 40"x 24" double basin. I would really like something thats in the 30-40" x 24" single basin so I can fit some larger items in the sink now and then. Anyone aware of a single basin free standing plastic utility tub like this? I've found stainless tubs like this but they cost a fortune. Thanks for the help.
