Overview

The Jabsco 58104-2000 is a replacement regular toilet seat and soft-close lid for Jabsco regular-size bowl toilets from 2018 onward. It fits the version with a flat edge at the back and the Jabsco logo on the bowl, and the lid measures 423 x 365 mm with 155 mm between the fitting holes.

This is the regular-size seat, not the compact version, and it uses a composite plastic seat with the hinge set included. The soft-close lid helps keep the head quieter and stops the lid from dropping hard when the boat moves.

Key features

• Fits Jabsco regular-size bowl toilets from 2018 onward with the flat rear edge and bowl logo
• Soft-close lid helps reduce slamming and cabin noise in the head compartment
• Composite plastic seat with a surface that wipes clean easily
• Lid size is 423 x 365 mm with 155 mm between fitting holes
• Hinges are included for replacement

Compatibility and fit

Check the bowl shape before ordering. This seat fits the 2018-onward regular-size Jabsco bowl and does not match the earlier regular bowl or the compact bowl version. The simplest visual check is the flat edge at the back of the bowl and the Jabsco logo on top.

For owners replacing a worn seat rather than the whole toilet, this part keeps the existing bowl in service without changing plumbing, wiring, or the toilet footprint.

Installation and setup

Replacement is straightforward when the bowl matches the correct 2018-onward pattern. With the hinge set included and the hole spacing fixed at 155 mm, the job is mainly a remove-and-refit swap rather than a modification project.

This is a good match for boats where the head gets regular use and where a lid that closes gently is worth having, such as family cruisers, fishing boats, and sailboats with enclosed heads.
