Marine Sanitation & Supply

Marine Sanitation & Supply sells marine and RV toilet systems and the parts that keep them running, with a focus on the VacuFlush line, composting toilets from Nature's Head, and holding tanks. The shop also carries repair kits for many toilet brands, along with pump-out fittings, water pumps and related plumbing supplies.

The company has been in business since 1976 and says it has been a marine sanitation specialist for a long time. Staff will help boat and RV owners work out which toilet fits their setup, and questions can be sent by phone or through the contact form. Office hours are weekdays in Pacific time, and the shop ships orders within the US, with free shipping on online orders over $99.
