The Pinnacle of RV Comfort
With its deep, round porcelain bowl, the Model 410 Complete delivers the refined feel and easy-care durability of premium porcelain in a compact design that saves valuable space.
More Comfort, More Space

Choose Your Profile And Finish
Standard Profile (19.625") Or Low-Profile (15.25")
Choose the fit that works best for your RV. The chair-height Model 420 delivers familiar, residential-style comfort, while the low-profile Model 421 is designed for bathrooms where steps, cabinets or raised platforms limit vertical space.
A Finish That Feels At Home
Choose the finish that feels at home in your RV. Crisp White creates a bright, clean and modern look, while warm Bone pairs beautifully with wood cabinetry, neutral finishes and softer interior color palettes – both finishes make it easy to coordinate your toilet with the style of your RV bathroom.
Luxury comfort and RV-ready engineering come together in the flagship 420 Series design.
