I use one of those giant rubbermaid 40+ gallon totes on the counter right next to my utility sink. Cut a hole in the end for a drain hose, and voila...huge ass cheapo sink.
For the spigot/sprayer I use a 6' length of garden hose with a shutoff valve nozzle on the end attached to my utility sink faucet.
In addition, I put a brass y adapter with shutoffs and garden hose disconnects on the utility sink faucet, so I can use the spigot in the sink without removing the garden hose.
I also highly recommend putting your brass jet bottle washer on a quick disconnect, super quick and easy changeovers.
