Cracked seat, stripped hinges, or a slow-close feature that stopped working? This genuine Lippert replacement seat kit brings your Flow Max RV toilet back to like-new condition without swapping out the entire unit. It is a direct, bolt-on fit -- no drilling, no adapters, no guesswork.
The Lippert Flow Max toilet was designed from the ground up to feel more like a home bathroom than a typical RV restroom. It uses a full-depth ceramic bowl at residential height, and the seat needs to match that geometry exactly. Generic seats from a hardware store will not align with the Flow Max mounting hole pattern, and an ill-fitting seat rocks, leaks air, and wears out faster.
Part number 2022121972 is the factory-matched replacement. It is engineered to the same hole spacing, seat width, and lid hinge geometry as the original, so installation is a straightforward swap using basic hand tools. No modifications to the bowl or floor flange are required.
Designed to match the factory mounting pattern on Lippert Flow Max elongated ceramic bowls -- seats drop in without modification.
Full-size elongated profile matches the deep Flow Max bowl for complete coverage and comfort comparable to a home toilet.
Kit ships with the seat, lid, seat base, mounting screws, adjustable seat blocks, and expanding nut seals -- everything needed to complete the install.
Smooth white plastic surface resists staining and wipes clean quickly. Lightweight construction does not add unnecessary load to the bowl rim.
The 2022121972 kit includes the following components:
Because this is the factory replacement -- not an aftermarket workaround -- the hinge spacing, lid geometry, and mounting footprint are built to the exact Flow Max specification. You get the same fit the toilet shipped with from the factory.
RV toilet seats take more abuse than home seats because they flex and vibrate on the road. Common signs it is time for a new seat include:
The expanding nut seals thread into the underside of the bowl rim. Tighten them finger-tight first, then snug with a wrench -- overtightening can crack the ceramic bowl rim. The adjustable seat blocks let you fine-tune the seat position so it does not slide forward on the bowl.
This seat kit is designed exclusively for Lippert Flow Max elongated ceramic RV toilets. It is not compatible with Lippert's round-bowl toilets, older Barker or recycled-water models, or any other brand of RV toilet. If you are unsure which Flow Max toilet you have, check the underside of the bowl for the Lippert part number or UPC label before ordering.
After installation, check the seat mounting hardware again after your first trip. Road vibration can loosen the expanding nuts slightly during initial break-in. A quick snug-up at the campsite keeps the seat solid for the season.
