4 Portable Sinks With the Largest Water Tanks


4 Portable Sinks With the Largest Water Tanks


Portable sinks make handwashing convenient and comfortable when you’re away from home. These sinks operate with water tanks, including a freshwater tank that pumps fresh water through the sink and a wastewater tank that holds used water. Most portable sinks feature a 5-gallon freshwater tank and a 5-7 gallon wastewater tank. This helps the sink move to different locations more freely. However, if your priority is to have fewer trips to refill and dump water tanks, then a portable sink with large water tanks is the solution.


Below we’ve listed five portable sinks with the largest water tanks we offer at All Portable Sinks. These are a combination of indoor and outdoor sinks, with both hot and cold water capability. There’s a large capacity portable sink for any type of event or facility!
