Jabsco Manual Marine Toilet – Regular Bowl – 29120-5000
The Jabsco Manual Marine Toilet (29120-5000) is a rugged, dependable sanitation solution designed for boaters who prefer a simple, power-free toilet system. Featuring a regular-size bowl for household-style comfort, this manual marine toilet is ideal for sailboats, cruisers, and vessels where reliability, efficiency, and ease of maintenance are essential.
Trusted worldwide, Jabsco manual toilets are known for their durability, smooth pumping action, and long service life in harsh marine environments.
Regular Bowl Comfort
The regular bowl design provides a seating size and height similar to a household toilet, offering greater comfort than compact marine toilets—especially on longer trips or for frequent use.
Manual Pump Operation – No Electrical Power Required
This toilet operates via a hand-pump flushing system, making it perfect for boats without electrical systems or for owners who want maximum reliability and minimal complexity. The smooth, ergonomic pump delivers efficient flushing and waste transfer without electricity.
Flexible Wet/Dry Flush Control
The integrated flush lever allows users to select wet mode for rinsing and dry mode for final evacuation. This helps conserve freshwater or seawater while ensuring effective waste removal.
Marine-Grade Construction
Built specifically for marine use, the 29120-5000 features corrosion-resistant materials, robust seals, and durable internal components. It is designed to withstand saltwater exposure, vibration, and heavy use.
Easy Installation & Serviceability
Designed to fit standard marine plumbing connections, this manual toilet is suitable for both new installations and replacements. Jabsco offers extensive availability of replacement parts and service kits, making maintenance simple and cost-effective.

Key Features & Benefits
1. Twist 'n' Lock™ Safety Handle
The standout feature of this model is the Twist 'n' Lock handle. After pumping, a 6$90^\circ$ turn of the handle locks the piston down, sealing the discharge outlet. This provides vital protection against "siphoning" and backflow, which can cause the bowl to overflow when the boat is heeling or in heavy seas.
2. Full-Sized "Regular" Bowl
Unlike "Compact" models that can feel small and uncomfortable, the Regular Bowl offers a larger seating area and a taller profile. This makes it much more comfortable for long-term cruising and liveaboard use.
3. Reversible Pump Mounting
The pump assembly can be mounted on either the left or right side of the bowl. This flexibility is essential for fitting the toilet into oddly shaped heads or tucked-away corners where plumbing access might be limited on one side.
4. Effortless Servicing
One of the reasons this toilet is so popular is that it is completely user-serviceable. Jabsco uses standardized parts that are available in almost every port in the world, allowing you to replace the seals, gaskets, or the entire pump assembly without removing the bowl from the floor.

Pro-Tip for Longevity:
"To keep your manual pump moving smoothly, avoid using harsh household chemicals like bleach, which can dry out and crack the internal rubber seals. Instead, use a specialized marine toilet lubricant or a small capful of vegetable oil poured into the bowl and pumped through once a month. This keeps the piston leather and O-rings supple and prevents the 'stiff handle' feel."
