Dometic M65-5000 All-In-One Marine Toilet – White with Wood Seat (312500001)
The Dometic M65-5000 is a self-contained marine toilet and holding tank system in a single unit — no separate holding tank installation required. Designed as a direct replacement for permanently installed portable toilets, it delivers a clean, odour-free freshwater flush with minimal water use. The ceramic bowl and enamelled wood seat give it a finished, residential feel that stands apart from standard marine heads.
Key Features
- All-in-one system: Integrated 6.5 US gal. (24.6 L) ABS holding tank eliminates the need for a separate tank installation — ideal for retrofits and simpler builds.
- Type III MSD certified: Meets U.S. Coast Guard Marine Sanitation Device requirements for use in U.S. waters.
- Ceramic bowl: More durable and easier to clean than plastic alternatives; resists staining and odour absorption over time.
- Ultra-low flush consumption: Uses less than 1 pint (0.39 L) per flush — conserves onboard fresh water without sacrificing flush performance.
- Pedal flush operation: Foot-operated flush mechanism keeps hands free and reduces contact points.
- Enamelled wood seat and cover: Fully enamelled for moisture resistance; more comfortable and durable than standard plastic seats.
- Odour-free freshwater flush: Uses onboard fresh water rather than raw water, eliminating the odour issues common with sea water flushing systems.
- 1½" discharge fitting: Standard sizing for straightforward connection to existing sanitation plumbing.

Parts Desk Insights
The M65-5000 is the right recommendation when a customer needs to replace a permanently installed portable toilet and wants a clean, self-contained solution without running separate holding tank plumbing. The ceramic bowl and enamelled wood seat are the key differentiators over the M65-700 plastic seat version — worth the price difference for customers who spend extended time aboard. Confirm the customer has an onboard fresh water supply plumbed to the head before recommending this unit; it requires fresh water input, unlike raw water flush systems. The 6.5 gal. tank is adequate for weekend use but will need pumping out on longer passages — set that expectation upfront.
