Dometic M65-5000 Marine Toilet, Type III MSD, 6.5 Gallon Tank, White with Enameled Wood Seat

The Dometic M65-5000 Marine Toilet is an all-in-one Type III MSD (Marine Sanitation Device) toilet and holding tank system in a single unit, built as a great substitution for permanently installed portable toilets. It combines a ceramic toilet bowl with a high-strength ABS holding tank rated at 6.5 gallons (24.6 L), giving it the durability of a fixed installation while remaining a self-contained unit.

The toilet uses an odor-free freshwater flush with low water consumption of less than one pint (0.10 gal / 0.39 L) per flush, making it efficient for onboard water use. A slow-close lid eliminates the noise and startle of a lid slamming shut in rough conditions or late at night. The seat is enameled wood for a residential feel, paired with a plastic toilet body finished in white, and the unit is foot-pedal operated for hands-free flushing.

Built by Dometic, the M65-5000 is designed as a self-contained marine toilet solution and does not require external plumbing beyond its own integrated tank, making it well suited for boats needing a reliable, low-maintenance head.
