Dometic Introduces 400 Series RV Toilet Platform
Dometic has introduced the 400 Series Toilet lineup, a new RV sanitation platform designed to make floorplan specification, replacement and upgrades easier.

Built on one of the industry’s first standardized RV toilet platforms, every model in the 400 Series shares the same 7.5-8 inch rough-in and universal 2-bolt mounting footprint, making upgrades, replacements and product specification seamless across the entire lineup, Dometic said in a recent release.
From the Essential 400 to the Complete 410 and top of the line Platinum 420, every model is designed to fit the same space. OEMs can simplify specifications. Dealers and service partners can simplify installation. RV owners can upgrade with confidence, without changing plumbing or modifying floorplans.
“It’s an industry first,” said Tim Hall, regional president for the Land Vehicle Americas Segment. “For the first time, OEMs and consumers can choose the toilet that best fits their needs without worrying about compatibility. Whether specifying an entry-level model today or upgrading to a premium option later, the process remains simple because every toilet in the platform shares the same installation foundation.”
One Platform. More Choice.
The 400 Series was built around a simple idea: give customers the freedom to choose the right toilet throughout the life of their RV, Dometic said.
A common installation footprint across the lineup means OEMs can streamline specifications across floorplans and trim levels, dealers and service centers can reduce installation complexity, and RV owners can replace or upgrade their toilet without replacing the installation footprint.
Designed for Easier Service & Better Everyday Performance
Beyond standardization, the 400 Series delivers the performance and comfort RV owners expect from Dometic, the company said.
A sealed gravity-flush system helps prevent odors between flushes. Enhanced rinse performance provides full-bowl coverage for a cleaner flush. Tool-free service simplifies maintenance, while a compact rear profile helps maximize bathroom space.
An 18-inch comfort-height seat improves accessibility and comfort, and a reinforced structure tested to support more than 700 pounds of front-load force delivers long-term durability.
A Flexible Solution for Every RV
Available in multiple configurations, including plastic and porcelain bowl options, the 400 Series makes it easy to match comfort, features and value to virtually any RV application, the company said.
Whether outfitting a new RV, replacing an existing toilet or upgrading to premium features, the 400 Series provides a simpler path forward.
More choice. Same footprint. Built for what’s next.
