Marine Toilets, Holding Tanks & Sanitation Systems
A reliable head is one of those things that goes unnoticed until it fails, and then it is the only thing that matters. CritPro carries marine toilets and sanitation systems built to work when you need them, as part of our full boating selection for boat owners who want a system they don't have to think twice about.
What to Look for in Marine Toilets & Sanitation Systems
Manual, electric, and vacuum flush toilets each fit different boats and different owners. Manual toilets are simple and reliable with nothing to wire up, electric units add convenience at the cost of pulling power and needing service eventually, and vacuum systems use less water per flush but come with a higher price tag and more parts that can need attention. Match the toilet type to how the boat actually gets used, not just what looks nicest in the showroom photo.
Holding tank size should match your typical time aboard, not just the minimum your boat came with, since running out of capacity mid-trip is never a good time. Check hose and fitting compatibility before replacing any part of an existing system, mismatched sizes are one of the more common causes of leaks and odor problems. Odor control, vented loops, and proper hose routing matter as much as the toilet itself for keeping a sanitation system working the way it should.
What This Category Covers
Marine toilets and sanitation systems at CritPro includes manual, electric, and vacuum flush toilets, holding tanks, deck pump-out fittings, sanitation hose, vented loops, and odor control products. Whether you are replacing a failing head or building out a new sanitation system, this category covers what keeps things working belowdecks.
Pairing Marine Toilets with Other Boating Equipment
Marine sanitation systems work alongside your boat's bilge and water pumps, and it's worth checking both systems at the same time since they often share similar hose routing and maintenance schedules. Our full boating selection covers everything else needed to outfit the rest of the boat.
