TMC Electric Marine Toilet 12V/24V – Full-Size Comfort Toilet with Macerator

The TMC electric marine toilet combines the comfort of a household toilet with the powerful performance of an integrated macerator, ensuring trouble-free operation on board. This is a full-size model – the bowl’s height and size are comparable to domestic toilets, meaning a more comfortable seating position and natural posture, which is especially appreciated during longer stays on your boat. The porcelain bowl has a smooth glaze that makes it easy to clean and resistant to staining. The flushing system can use raw water or fresh water (depending on your setup) – the pump is self-priming and capable of installation either above or below the waterline.

Key features:

• Macerator System: At the heart of the toilet is an electric motor with a cutting mechanism that provides simultaneous flushing and waste maceration. With a flow rate of roughly 20 liters per minute, this pump can rapidly send waste to a holding tank or overboard discharge (where permitted). The macerator blades are made of stainless steel, capable of enduring heavy use without dulling or corrosion.
• Voltage Options: The model is available in a 12V and a 24V version. The 12-volt version suits most small to mid-sized boats that run on standard marine batteries. The 24-volt version targets larger yachts and commercial vessels with 24V power systems – this eliminates the need for a step-down converter and ensures optimal performance at the intended voltage. Both versions deliver the same pumping power and efficiency.
• Included Fittings & Valves: The toilet comes with a set of standard hose connectors for the inlet (∅19 mm / ¾″) and outlet (∅25 mm or ∅38 mm / 1″ or 1½″ with adapter). It features a built-in check valve and siphon-break loop to prevent backflow and unwanted siphoning, especially important for below-waterline installations. These safeguards keep your head compartment dry and your system safe.
• Sturdy Base & Mounting: The toilet’s base is solid and steady, and can be securely bolted to the floor/deck via four bolts. Despite its weight (~23.5 kg / 52 lbs), installation is relatively straightforward with two people. Its dimensions (approximately 48 cm L x 36 cm W x 45 cm H / 19″ x 14″ x 18″) make it suitable for medium to large boat heads.
• Easy Maintenance: TMC is a reputable manufacturer whose parts and consumables (seals, impellers, etc.) are widely available. This means if maintenance is needed – such as replacing gaskets or servicing the pump – you can easily find spare parts. The seat is a standard size and can be swapped out when worn with any universal marine seat or an original TMC replacement.

Usage & Recommendations: This electric toilet is recommended for yachts and boats around 26 feet and up, where crew comfort is a priority and space is available for installation. The full-size model is also well-suited for sailing catamarans, houseboats, and cruiser motorboats, where occupants spend extended time aboard. For smaller vessels or as a second head, a compact model might be considered, but as the primary bathroom on a cruiser, this TMC unit delivers unmatched comfort. With its quiet operation and dependable performance, it meets even demanding needs – turning your onboard toilet into a safe, hygienic, and user-friendly system for all.*
