Thetford Porta Potti 345 Portable Boat Toilet, Piston Pump Flush, White

The Thetford Porta Potti 345 is a portable boat toilet built for boats, RVs, and off-grid use where a permanent marine head is not practical. It pairs a manual piston pump flush with a high-capacity waste holding tank, giving it a larger fresh water and waste capacity than Thetford's smaller Porta Potti models. The two-piece design separates a fresh water flush tank from a sealed waste holding tank, with a valve system that keeps odors locked inside between uses.

The 345 features an integrated cover-lock, a redesigned fill cap and pump, and an integrated pour-out spout for easy, mess-free emptying. The seat and cover use a cleaner design for improved comfort, and an ergonomic carry handle makes the unit easy to lift and transport to a dump station or shoreside facility. The valve handle system has also been improved for smoother operation. Constructed of durable plastic in a white finish, the Porta Potti 345 is designed to be easy to use, easy to clean, and long lasting with regular use aboard a boat or in an RV.
