R/F UNIV ONYX 20FT

The Dometic 400 Series toilets are designed for RVs, offering a compact fit with a shortened rear profile to reclaim bathroom space. They feature residential-style seating and quiet, soft-close comfort. Built on a unified platform, the 400 Series (which includes models 400, 410, and 420) provides seamless installations and upgrade options, allowing users to choose between heavy-duty plastic or premium porcelain, and round or elongated bowls. Installation is simplified with a standard 7–5/8" rough-in, universal 2-bolt mount, and tool-free seal replacement. These toilets are tested to withstand 150,000 flush cycles and double the competitor's weight load capacity, ensuring reliability. They are assembled in the USA.
