SEAFLO Large Electric Flush Marine Toilet
Model SFMTE1-01-R operates at 12V and draws up to 20A. It features a ceramic bowl, soft-close seat, and a built-in backflow preventer. This model is designed for a larger head, offering a robust dual-function pump that rinses and evacuates waste. Best for boats with roomy bathrooms and crews that require strong flushing performance. It suits experienced boaters who want a permanent, heavy-duty electric head and value a 4-year warranty. A limitation is higher power draw compared to smaller units, which may impact electrical planning on smaller vessels.
SEAFLO Quiet Flush Electric Marine Toilet
Model SFMTE1-03-R provides 12V operation with a 4-year warranty. It uses a three-way switch panel and includes a macerator solenoid valve. Notable for its ultra-quiet flush operation, this unit is best for boats where minimizing nighttime noise is a priority. It supports standard 3/4″ inlet and 1″ outlet plumbing. Choose this if quiet performance is your top criterion, but be aware that its max draw sits around 16A, slightly lower than some larger SEAFLO heads.
SEAFLO 12V Electric Marine Toilet – Compact Size
This compact model offers a 12V push-button flush with a ceramic bowl and a 4-year warranty. Its dimensions fit smaller heads while delivering dependable electric flushing and maceration. It’s best for small boats or guest heads where space is tight. A limitation to consider is that its footprint is smaller, which might influence capacity and ease of cleaning compared to larger SEAFLO models.
Johnson Pumps AquaT Compact Electric Marine Toilet
This compact white vitreous porcelain unit combines a corrosion-resistant design with a built-in disposal and flushing pump. It’s a practical choice for boats needing a straightforward, reliable electric head with a compact footprint. Best for owners prioritizing simple maintenance and durability in a compact space. Limitations may include fewer high-tech features than some SEAFLO models, depending on installation needs.
Jabsco 37010 Electric Marine Toilet
Jabsco 37010 features a self-priming rinse pump with flexible discharge options and a built-in backflow preventer. It’s well-suited for boats needing robust backflow protection and adaptable discharge routes. Best for boats that require reliable, flood-safeguarded operation in varying plumbing configurations. A potential limitation is that some installations may require careful plumbing routing to accommodate discharge options.
SEAFLO Deluxe Flush Freshwater Electric Marine Toilet
Model SFMTE1-05 uses a freshwater rinse with a four-way flush panel and a smart flushing system. It includes a quiet flush and macerator pump, backed by a 4-year warranty. Best for boats that prefer freshwater rinsing and more control over flushing cycles. It is larger than some compact units, so consider head space and mounting requirements. Caution: higher water usage due to freshwater rinse in some configurations.
Buying Guide
- Head size and space: Measure available space to choose compact versus large models. Compact heads save room but may have smaller bowls.
- Waste management: Consider built-in macerators and backflow preventers for safety and reliability, especially on boats with liveaboard crews.
- Electrical draw: Check voltage and current draw. Higher power heads can affect battery and alternator sizing on smaller vessels.
- Flush control: Decide between push-button panels and remote switches. Three-way panels offer more control but require wiring planning.
- Noise level: If quiet operation is important, prioritize Ultra-Quiet Flush or models marketed as low-noise.
- Water source: Freshwater rinses reduce residue but require water supply considerations; seawater options kill odors differently.
- Warranty and maintenance: A multi-year warranty provides long-term protection against marine wear and corrosion.
- Discharge routing: Plan for discharge height and hose connections; some models support higher lift or flexible discharge paths.
