As the flagship model in the Dometic 400 Series, the Dometic Model 420 Platinum RV Toilet delivers a luxury residential bathroom experience without needing extra space. It features a full-size, elongated porcelain bowl, 19" seat length, and 18" chair-height for maximum comfort. Thanks to a compact rear profile and 7.625" rough-in, its universal replaceability makes the 420 truly one of a kind by allowing it to fit in spaces that other elongated models can't. Built for long-term durability that's easier to clean, the 420 is the ultimate upgrade for RV owners who desire true home-like comfort on the road. One-of-a-Kind, Industry-First Design â The first and only porcelain toilet that brings luxury comfort to any RV â designed to fit where competitors and other porcelain models, like the Dometic 310 and 320, simply can't. Elongated Premium Porcelain Bowl â Enjoy the ultimate at-home experience of an elongated porcelain bowl with its durable, scratch-resistant surface that's easier to clean while providing high-caliber stain and odor resistance. Drop-In Upgrade â Engineered for a simple swap, the universal 2-bolt mount and shared footprint fit any standard RV rough-in of 7.625" or greater. This provides a seamless replacement for competitor toilets or an easy upgrade of any model in the 400 Series without layout changes. Fits Where Others Won't â Signature compact rear profile is specifically designed to save space, allowing installation in tighter layouts while freeing up valuable floor space. Designed for Convenience â The residential-style, soft-close seat and lid feature an easy-to-clean, position-lock hinge to hold the lid up when needed and to quietly close with a soft tap without slamming. Cleaner, Quieter, and More Efficient â The best-in-class 360° Powerflush system is engineered for power and efficiency to provide complete bowl coverage for a spotless, quiet rinse while using less water. Leak-Free Design and Odor Prevention â Redesigned sealing and bowl contours prevent internal leakage and eliminate odor buildup, improving reliability and offering a cleaner, more comfortable bathroom experience. Worry-Free Performance â The integrated sealed gravity system ensures odor containment, and the glass-reinforced, sonic-welded one-way water valve prevents cross contamination for a clean and fresh bathroom.
