Tecma Electric Toilets and Bidets

The sanitation system on a boat is one of the most heavily used and complex systems to manage. Choosing an electric toilet means striking a balance between domestic comfort and marine technical requirements: the system must be capable of macerating waste, managing pumping to the black water tank, and resisting constant salt corrosion. Tecma models use pump-based maceration systems that allow discharge pipes to be kept at a small diameter, making it easier to route them through under-deck channels where space is always limited.

When evaluating a replacement or a new toilet installation, the first aspect to check is the physical footprint and the position of the discharge outlet. Many mistakes arise from failing to account for the distance between the mounting base and the pipe exit point at the bulkhead or floor. Another critical point is current draw: remember that a 12V or 24V toilet requires correctly sized cables to avoid voltage drops that would reduce the motor startup torque, causing jams during the flush cycle.

Black water management on board does not allow for approximation. A well-designed system must include effective check valves and properly sealed gaskets to prevent odors from rising. If your boat is longer than 10 meters, also carefully evaluate whether the discharge pump can handle the elevation between the toilet and the holding tank, always checking the manufacturer's head pressure data against your specific on-board configuration.

Nautiba steps in here to spare you incorrect purchases. As technical specialists, we analyze system compatibility before you choose the product. If you have doubts about fixing hole compatibility or the capacity of the existing electrical system, contact us for a technical discussion. Our order management is based on clear ETAs, allowing you to plan maintenance work without long waits or uncertainty about parts availability.

Selection and Installation Criteria

• Always verify the on-board voltage (12V or 24V) to avoid damage to the electric motor.
• Check the actual bowl footprint, especially the depth, to make sure it does not interfere with bulkheads or doors.
• Make sure the discharge hose diameter is compatible with the chosen macerator pump to prevent blockages.
• Plan the position of the control unit in a dry location, away from possible water ingress.
• Verify whether the current configuration uses fresh water or sea water for flushing to select the correct solenoid valve.

How do I choose the correct voltage for the toilet?

The choice between 12V and 24V depends entirely on the battery bank installed on your boat. A 12V toilet connected to a 24V system would be damaged instantly. Always check the label on the motor or the control unit of the toilet you are replacing.

What happens if the discharge diameter is too small?

If the pipe diameter is not adequate for the pump flow rate, you risk frequent blockages and motor overheating due to excessive back pressure. Always follow the manufacturer's technical guidelines on minimum diameters.

Is it possible to install a separate bidet?

Available space is the main limiting factor. If you do not have room for a dedicated bidet, Tecma toilet models exist that integrate bidet functions, optimizing the footprint without sacrificing comfort.

How can I prevent odors in the system?

Odors often stem from seawater stagnating in the hoses or from inadequate venting of the black water tank. Make sure the trap is always properly primed and that the tank vent hose is clear and correctly sized.

Is maintenance on electric toilets complex?

Routine maintenance is limited to checking the seals and periodically cleaning the macerator pump. Avoid flushing non-specific toilet paper or foreign objects down the toilet, as they can jam the macerator blades.
