Laundry/Utility Sink

I'm looking for a 20 gallon polyfoam laundry sink the can be mounted on the wall. I've found a few on the Internet, but was wondering if anyone has recommendations. It must be at least 20 gallon capacity as we use it to bathe our dog. Thank you.

Almost all, if not all, manufacturer's of leg type sinks, also have the wall hanger kit. Just be sure to have something solid in the wall to fasten it to.
