Jabsco Manual Marine Toilet – Regular Bowl with Soft Close Lid – 29120-5100
The Jabsco Manual Marine Toilet (29120-5100) combines traditional hand-pump operation with modern convenience, featuring a regular-size bowl and a soft close lid for quiet, comfortable use. Designed for boats without electrical systems or as a reliable backup toilet, this manual head delivers rugged durability, smooth pumping, and long-lasting marine-grade performance.
Ideal for sailboats, cruisers, and recreational vessels, this model allows boaters to enjoy a familiar, household-style toilet experience even in remote areas.
Regular Bowl Comfort with Soft Close Lid
The regular bowl design provides ample seating comfort comparable to a residential toilet. The soft close lid prevents slamming, reduces noise, and enhances onboard convenience, making it ideal for shared cabins or overnight trips.
Manual Pump Operation – No Electricity Required
This manual marine toilet operates via a hand pump, delivering reliable flushing and waste evacuation without the need for electricity. The ergonomic pump ensures smooth operation while giving users complete control over water usage.
Wet/Dry Flush Control
The integrated lever allows for wet flush to rinse the bowl and dry flush for final evacuation. This flexibility conserves freshwater or seawater while ensuring efficient waste removal, making it practical for extended trips or limited water supply scenarios.
Durable Marine-Grade Construction
Built to withstand harsh marine environments, the 29120-5100 features corrosion-resistant components, durable internal seals, and a robust ceramic bowl. It is engineered to resist saltwater, vibration, and heavy use for long-lasting reliability.
Easy Installation & Service Support
This manual toilet fits standard marine plumbing connections and is ideal for both new installations and replacements of older or failing manual heads. Jabsco’s widely available replacement parts and service kits make maintenance and repairs simple.

Key Features & Benefits
1. Twist ‘n’ Lock™ Safety
By turning the handle $90^\circ$ at the end of the stroke, you lock the piston against the discharge valve. This creates a physical barrier that prevents "siphon flooding"—a critical safety feature for toilets installed below the waterline or on sailboats that heel significantly.
2. Soft Close Luxury
Standard manual toilets often have lightweight lids that "clack" and slam with the motion of the boat. The Soft Close hinges ensure the lid lowers gently and silently. This protects the porcelain bowl from impact cracks and keeps the boat quiet during night-time use.
3. "Regular" Household Dimensions
The 29120-5100 provides a larger seating area and a more natural height compared to "Compact" versions. It is the preferred choice for cruisers and liveaboards who want the simplicity of a manual pump without sacrificing comfort.
4. Reversible Pump Mounting
The pump assembly can be mounted for either left-handed or right-handed operation. This allows you to orient the pump away from bulkheads or toward the center of the head for easier access and maintenance.

Pro-Tip for Maintenance:
"The most common failure point on any manual toilet is the Joker Valve located inside the discharge elbow. If you notice water 'leaking back' into the bowl after you've pumped it dry, the Joker Valve is likely worn or encrusted with calcium. Replacing this valve annually will keep your pump efficient and prevent unsightly backflow."
