Compact portable toilet for RV, van, boat, camping, and emergency use. 2.6-gallon fresh and waste tanks, bellows pump flush, rotating pour-out spout, sealed valve, standard lid latch. 15" L x 13-7/16" W x 12-1/4" H. ~27 flushes per fill. Previously known as Thetford part number 92860.
The Thetford 50031 is the Porta Potti 135 — the entry-level model in Thetford's Porta Potti lineup, and the most compact and affordable option for occasional or backup use. Previously known as Thetford part number 92860, this is the same proven portable toilet under an updated part number.
The 135 carries equal-capacity 2.6-gallon fresh and waste tanks, providing approximately 27 flushes per fill. The bellows pump flush mechanism requires no batteries or electricity — just a push of the pump button to rinse the bowl. The sealed valve locks odors in the waste tank, and the rotating pour-out spout makes emptying at any dump station or restroom cleaner and less messy. Compact enough to fit under a seat, in a closet, or in a vehicle storage area, the 135 is the practical choice for camper vans, smaller boats, trucks, and backup emergency use. White/gray color.
