this is what you want. yes, its alot more cash vs a regular laundry/utility sink. but you can maybe find used one on craigslist/facebook or if there's any place to get used restaurant equipment near you. i've bought a few for under 100 at restaurant auctions.
sink is great for washing. obviously. but also having a place to put stuff is SO MUCH better. and these commercial style units can easily have casters put on the feet so you can roll it around if you wanna do a mobile wash station like mentioned above.
