Plastic Seat and Lid for TMC Electric Marine Toilet – Replacement Set

This plastic seat and lid are designed as a direct replacement for the originals on TMC electric marine toilets. If your current seat is cracked, discolored, or simply showing its age, swapping it out for this new one will instantly refresh the look of your toilet and improve comfort during use. The plastic used for the seat and lid is specifically chosen for marine conditions – it won’t yellow or warp from moisture, will not corrode (unlike metal hinges), and is UV-resistant, so it won’t crack or degrade quickly even with sun exposure.

The kit comes complete with hinges and fasteners. The hinges are made of non-corroding materials (high-grade plastic or stainless components), ensuring smooth motion when lifting or lowering the lid without squeaks. Installation requires no special tools: simply unscrew the old hinge bolts, remove the old seat and lid, and attach the new ones using the provided screws and nuts. The sizes and mounting holes exactly match the factory originals, so no drilling or adjustments are needed – the whole process literally takes a few minutes.

• Compatibility: This replacement set fits the standard TMC electric toilet model (with a porcelain bowl roughly 36 x 34 cm in size). If you have a compact version or a different model, double-check fitment – most TMC toilets share the same bowl oval, so this seat typically fits.
• Improved Comfort & Appearance: The new seat sits firmly without wobble. The clean white plastic gives your head a fresh, tidy appearance and greatly improves the user experience, especially if the old seat was scratched or discolored.
• Easy Care: The plastic surface cleans easily with normal bathroom cleaners or mild soap – it’s glossy and non-porous, so it won’t absorb odors or harbor bacteria. This contributes to better onboard hygiene and odor control.
• Practicality: Keeping a spare seat on board can be useful during extended voyages – while uncommon, breaks can happen (for instance, if someone accidentally steps on the lid or a heavy impact occurs). With this set, a broken seat can be replaced immediately so you can continue your trip with a fully functional toilet.
