Dometic 320 Series Standard Height Toilet, Bone - RV Ceramic Upgrade

Our review of the Dometic 320 Series Standard Height Toilet, Bone finds it best suited for RV owners who want a durable, residential-style replacement that looks and feels closer to a home bathroom. The single biggest reason to consider this model is the combination of a deep, 100% vitreous ceramic bowl and a full-size wood seat, which together deliver a markedly improved rinse and seating experience over typical lightweight RV units. Installation is straightforward for most rigs and the gravity flush paired with an ergonomic foot pedal keeps operation simple and water-efficient.

Key Features

• Full-Size Wood Seat: Provides the comfort and appearance of a home toilet while fitting most RV toilet footprints for an immediate upgrade in feel.
• 100% Vitreous Ceramic Bowl: The deep ceramic bowl resists staining and cleans easily, making maintenance less frequent and more thorough than plastic alternatives.
• Efficient One Pint Flush: Uses only one pint of water per flush, conserving freshwater supplies without sacrificing basic rinse performance.
• Rim Design Prevents Spills: The rim profile reduces splash and keeps the bathroom area cleaner during use and flushing.
• Ergonomic Foot Pedal: Partial press adds water while a full press triggers a gravity flush, allowing simple, intuitive control for varied needs.

Who It's For

This toilet is ideal for RV owners who want a heavier-duty, residential-style replacement that prioritizes durability and cleaning ease. It suits those who value a ceramic bowl and a wooden seat for comfort and appearance, and who need a water-efficient option to stretch onboard supply.

It may be less appropriate for users seeking ultra-lightweight components for weight-sensitive vans or for those who require a composting or macerator system; also, buyers wanting a wholly maintenance-free, unbreakable material should consider that ceramic, while long-lasting, requires care during handling and installation.

Pros & Cons
