where can I buy a portable sink?

Portable sinks are great, because you can take them with you anywhere you go, so you won't have to walk to the sink.

The CamKiosk® Hand Sink Cart is a 2 compartment sink that has polycarbonate construction, two 5-gallon fresh water tanks and one 7-1/2 gallon refuse tank, 2-1/2 gallon hot water heater, paper towel holder and soap dispenser, 6" casters (2 fixed and 2 swive l), 110 v. The Cambro KSC402 CamKiosk portable self-contained hand sink cart is a great way to allow employees or customers to wash their hands when you're nowhere near a water hookup! Once filled, all you need is a 110V electrical connection! Two 5 gallon fresh water tanks and two 7.5 gallon refuse tanks provide approximately 70 hand washings per fill. The Cambro KSC402220 self- contained hand sink cart features a water heater with a 2.5 gallon capacity that heats up water in 10 minutes, so you can run either cold or hot (up to 140 degrees Fahrenheit) water to the faucet. These tanks are easy to insert and remove for filling and emptying. An NSF listed water pump supplies the water to the faucet.
