Dometic 9610008283 Model 421 Platinum RV Toilet Elongated Porcelain Bowl Low-Profile White

The Dometic Model 421 Platinum RV Toilet (MPN: 9610008283) is the flagship low-profile toilet in Dometic's 400 Series lineup, delivering a true residential bathroom experience in a space-saving design. Featuring a full-size elongated premium porcelain bowl, this gravity-flush RV toilet is built for full-timers and frequent travelers who demand maximum comfort on the road.

The 421 is the low-profile variant in the Platinum Series, with a 13-5/8" seat height — ideal for RV bathrooms with limited vertical clearance caused by steps, cabinetry, or a raised platform. Despite its compact profile, the elongated bowl delivers the comfort of a residential toilet. The porcelain construction resists scratches, stains, and repeated cleaning chemical exposure far better than plastic alternatives.

Engineered for easy installation, the 421 features a universal 2-bolt floor mount and an industry-leading 7.625" rough-in distance — the shortest in the industry — allowing it to seamlessly replace virtually any existing RV toilet, including competitor brands and prior Dometic 300 or 400 Series models, without any layout modifications.
