BOATS

The C-Head solves three big problems for marine toilets; it requires no water or plumbing, it doesn’t have the pervasive sewage smell so common with marine heads, and most importantly, the waste can be easily stored on board until it can be disposed of, creating no urgency to dump the waste overboard, ever! Depending on the space configuration for the head on your boat, one of three C-Head models will generally fit your needs.

 

Below is our recommendation for the C-Head toilet that works best with Sailboats, Trawlers, and Houseboats.

Basic C-Head

The basic marine C-Head is the toilet of choice if you have a space that is 16” wide and 20” front to back (allow another 16” knee space ahead of the front). Clearance above the seat should be about 36″ for headroom. Check doors and drawers for clearance. Use a quick release anchoring system if the toilet is blocking necessary access panels. While this amount of room is common on houseboats and most trawlers, it is usually not the case on sailboats under 40 ft. LOA.

Wedged-Back 
C-Head

The wedged-back model is good for installations where the toilet is backed up against a section of the sloping hull side, for corner installations, or in the bow of a boat. The top of the toilet is wider than the base and this will affect some installations. In corners where one side is a sloping hull which widens as the corner rises, this tends to be less of an issue.

Shorty

 C-Head

The shorty is designed for installations on top of pedestals or in areas where overhead clearance is minimal such as pocket cruisers. This toilet is also wedged in the back on the sides which allows for more fitting flexibility with pedestals where the hull intrudes at the back. With many pedestal installations, the pedestal may need to be extended for foot placement. Download and read the owner’s manual for ideas and information on this type of installation.

We offer wood grain finishes for all of our models using Wilsonart® brand high pressure plastic laminate. Giving you a satin finish for an elegant look to match your space.

Golden Teak, Red Mahogany , and Dark Mahogany options available on checkout.

General C-Head Composting Toilet Considerations

Make sure that you can access any panels around the toilet area in an emergency if needed and check to see that the toilet is not going to block any drawers or doors. If the head needs to be moved frequently or in emergencies, consider using the rubber latch tie-down accessory.

 

You can drain the urine into the existing holding tank for convenience using an EUD if the holding tank is below the toilet on all angles of pitch and heel. This will extend the use of the holding tank considerably since no water or minimal water is mixed with the urine.

 

On some Houseboats you may encounter a standard toilet flange on the floor. Consider using a bottom exit kit BEX kit for this installation to extend the use of the holding tank. (Available for the Basic model only).

 

With sailboats, the location of the holding tank will dictate your choices as many or most holding tanks are installed above the toilet requiring a pumping mechanism to move the urine from the toilet to the tank. Consider ordering the pump tank accessory for this situation. Refer to the owner’s manual for ideas on pumping mechanisms.

 

While 12 feet of ventilation hose and the PVC fittings are included, you normally will not need to ventilate the toilet if you empty it once a week and keep it filled with fresh medium when not in use. For more information on ventilation consult the Owner’s Manual.

 

Vessels that run offshore should consider using the P-tank accessory as it is designed to withstand agitation without leaking, especially if the head is located near the bow of the boat. The alternative is to be mindful to empty the plastic urine jug if the boat is entering rough seas.
