RV Toilets & Parts
An RV toilet is a different animal than the one at home — no big water tank behind it, a rubber ball or blade seal at the bottom of the bowl instead of a trap, and everything sized to work off a 12-volt pump and a black tank. This section splits three ways: the fixed toilets that bolt to the floor and drain into your black tank, the portable and cassette units for rigs and campers without a permanent setup, and the seals and pedal parts that keep an aging toilet from leaking or losing water in the bowl.

Sorting out RV toilet types and parts
Which category you need depends mostly on whether your rig has a black tank plumbed in. A fixed RV toilet drains straight down into that tank and flushes with your onboard water; a portable or cassette toilet carries its own waste holding and gets emptied at a dump station or into a home toilet. Both wear out at the seal long before the bowl does, which is the third piece here.
- RV Toilets. Floor-mounted gravity-flush toilets that drain into your black tank — Thetford Aqua-Magic, Dometic 310, and Camco ceramic units in high- and low-profile heights and plastic or china bowls.
- Portable & Cassette Toilets. Self-contained units with their own fresh and waste tanks — Thetford Porta Potti, Camco bucket and travel toilets, and cassette tanks for rigs without a black tank.
- Toilet Seals & Repair Parts. The bits that fail with age — flush ball seals, foot pedals and cables, seat and cover assemblies, closet bolts, and blade springs to rebuild a toilet instead of replacing it.
If the bowl won't hold water overnight, start with the seals category before you shop for a whole new toilet — a leaking flush seal is a cheap fix. When the tank side is the problem, the tank care and sewer categories one branch over handle odor and dumping.
