TMC Manual Marine Toilet – Compact & Sturdy (473 x 416 x 330 mm)

The TMC manual marine toilet is a classic choice for boats, combining simple operation with durability. Built for heavy-duty use in the marine environment, this toilet features a robust porcelain bowl comparable in quality to household toilets. The pump unit is mounted on the side: with a few strokes of the handle, the user pumps clean seawater (or freshwater) into the bowl while simultaneously drawing waste out through the discharge hose. The dual-action hand pump makes flushing quick and efficient.

Key features and advantages:

• Marine-Grade Materials: All metal components (bolts, brackets) are made of stainless steel to prevent rust. The pump piston and valves are crafted from tough plastics that resist damage from saltwater. This ensures a long service life even with daily use.
• Wet/Dry Switch: The toilet includes a lever or valve that lets you select between a “wet” flush (the pump brings in water to rinse) and a “dry” flush (pumping out only). This is useful when you want to leave the bowl dry after use or before rough seas to avoid sloshing.
• Safe Below-Waterline Use: If installing the toilet below the waterline, the instructions call for adding vented loops on the intake and discharge hoses. The toilet has an internal check valve in the pump to prevent backflow into the bowl. These measures eliminate the risk of unintended siphoning or flooding.
• Compact & Ergonomic: Its dimensions (about 416 mm width, 473 mm depth, 330 mm height) allow installation in small spaces. Despite the modest height (33 cm / 13″), it offers a relatively comfortable seating position. The base shape is designed to cover the mounting bolts and be easy to clean around.
• Easy Maintenance: Manual toilets are known for their straightforward design – if service is needed, the pump can be disassembled for cleaning or seal replacement (repair kits are available). Seasonal maintenance typically involves flushing with fresh water and adding lubricant to the piston, which can prolong the life of the rubber valves.

Usage & Purpose: The TMC manual toilet is suitable for sailboats and powerboats roughly 16–40 ft, where electrical power may be limited or owners prefer simplicity and reliability. It is commonly found on sailing yachts since it uses no electricity and operates quietly – appreciated during overnight passages. It’s also an excellent choice as a backup head on larger vessels or expedition yachts, as it has minimal failure points. With this toilet on board, you have the assurance of mechanical dependability – it will always function as long as you can pump, providing basic comfort regardless of conditions.
