The Thetford Porta Potti 335 is a white toilet with a 2.6 gallon capacity, measuring 12.2 inches high, 13.5 wide and 15 deep. A piston pump flushes it, and a level indicator shows when it is time to empty. The seat and cover lift off for cleaning, and a rotating pour-out spout is built in. A sealed valve keeps odors in the holding tank. Plumbing it to a holding tank or overboard discharge needs the separate MSD fitting, part 363-40158.

Our take

A level indicator on this 2.6 gallon unit shows when it is time to empty, and the sealed valve keeps odors in the holding tank until then. Plumbing it to a holding tank or overboard discharge takes a separate MSD fitting, which is an extra part to source.

From our buying guide

A vessel with installed toilet facilities must have an operable marine sanitation device that is labeled or certified. EPA says untreated sewage may not be discharged within three miles from shore, and in a No Discharge Zone treated sewage may not be either.

Check before you buy:

  • You have what it needs, since heads may call for 12-volt power, through-hulls and seacocks, or a separate vacuum source.
  • It fits the compartment, since Jabsco says an electric toilet needs more space at the rear than a manual one.
  • If it could sit below the waterline, you'll fit a vented loop as the maker specifies, since Jabsco warns the vent, not the loop, is what stops the siphon.
