Why Choose the Dometic 400 Essential RV Toilet?

Featherlight & Durable Construction

Fits Where Others Won’t

The compact rear profile is engineered specifically for tight RV bathrooms, freeing up valuable floor space and allowing installation in layouts where bulkier toilets won’t fit.

Designed for Everyday Convenience
