The Thetford Nano Premium Plus is a 12V compact macerating toilet made of Italian ceramic. It can flush with raw water or pressure water, and it uses 2 check valves along with a water trap. Flush rate runs 0.1-0.7 gallons per flush. The outlet pump manages 13.1ft of vertical suction and 131.2ft of horizontal suction and calls for a 30A fuse, while the raw water inlet pump works at 45 PSI.

Our take

The outlet pump pulls 13.1ft vertically and 131.2ft horizontally, which leaves room in how the discharge is routed. It takes either raw water or pressure water for the flush, and the outlet pump wants a 30A fuse, so plan the wiring for that.

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.
