It emphasizes ultra-quiet flush operation and a standard 3/4″ inlet with 1″ discharge. Best for crews needing minimal noise during overnight passages.

Buying Guide
What to consider when choosing a macerator toilet for boats:
- Power supply: Decide between 12V and 24V systems based on your boat’s electrical configuration and available battery capacity.
- Discharge size and routing: Ensure inlet and discharge sizes align with your plumbing; larger boats may benefit from 1-1/2 inch discharge.
- Noise level: Quiet flush models improve overnight comfort in cabins; consider decibel expectations and mounting considerations.
- Macerator performance: Look for a model with a capable macerator pump to handle waste efficiently and reduce clog risk.
- Warranty and durability: A multi-year warranty is valuable for marine environments with salt, vibration, and temperature variations.
- Upgrade path: If starting from manual heads, a conversion kit can offer an economical upgrade without full system replacement.
- Maintenance needs: Raw water rinse options may require more mineral management; factor in ease of cleaning and servicing.
