Portable toilets are at the heart of our operation and we offer several different models for rental. The Pro-Serve 60-gallon tank portable restroom features a smooth interior, a deep sump below the toilet bowl, and a simple clean design. Our newly-introduced Pro-Serve 40-gallon tank uses a flushing system to operate, but can also use a smaller, drop lid tank when desired. In addition to these features all Portable Toilets at Portable Restroom Solutions come equipped with a urinal and a double-roll toilet paper cover with rod and padlock.
