Customers choose the 300 Series for its dependable performance, straightforward installation, and long-term serviceability — making it a smart choice for RVers who want comfort and convenience on the road.
Bowl Material & Build
The Dometic 300 Series toilets are built with heavy-duty, impact-resistant plastic bowls and bases designed to withstand the rigors of RV travel. While lighter than ceramic options, the construction remains sturdy and easy to clean, with smooth surfaces that resist staining and odors. The plastic build makes them ideal for owners who want durability without unnecessary weight.
Seat & Lid
These models often include a residential-style seat and cover, providing a familiar and comfortable user experience. Some versions may feature a slow-close seat, which adds convenience and reduces noise — especially in small RV bathrooms. The seats are wide enough for everyday comfort yet maintain the streamlined design needed for compact spaces.
Weight
A key advantage of the 300 Series is its lightweight construction. The durable plastic materials keep the overall toilet weight minimal, helping RVers meet travel weight limits and simplify installation. This makes the 300 Series especially appealing for smaller RVs and trailers where weight conservation is important.
Comfort & Feel
Despite their lightweight build, Dometic 300 Series toilets offer a comfortable seating experience with thoughtfully designed bowl contours and seating height. The gravity-flush system delivers effective flushing with minimal water use, providing both performance and comfort for daily use on the road.
Available Options
The Dometic 300 Series includes high-profile (300) and low-profile (301) versions to fit a variety of RV bathroom layouts and space requirements. Color options typically include white and bone, making it easier to match existing interior schemes. Many models also offer optional hand sprayer attachments or compatibility with aftermarket accessories to enhance hygiene and cleaning convenience.

Whether you’re upgrading your RV bathroom or replacing an aging unit, Dometic’s 310 Series provides practical features and trusted engineering that make life on the road more comfortable—and cleaner.
Bowl Material & Build
The Dometic 310 Series toilets are constructed with rugged, impact-resistant plastic bowls and bases engineered for mobile use. This lightweight yet durable design resists staining and corrosion while making cleanup easier. The smooth plastic surfaces maintain hygiene and reduce odor adherence, giving you a dependable bowl that’s built to last through frequent travel and use.
Seat & Lid
These models typically include a residential-style toilet seat and cover designed for comfort and ease of use. Some configurations offer soft-close seats or higher seating profiles that improve accessibility and everyday comfort—especially for taller users or longer stops. The seating is designed to feel familiar and stable, even in tight RV bathroom spaces.
Weight
A key advantage of the 310 Series is its lightweight construction, which helps RV owners stay within towing and payload limits. The plastic design keeps overall weight low without sacrificing durability or flushing performance, making these toilets ideal for weight-sensitive RV applications such as travel trailers and compact motorhomes.
Comfort & Feel
Despite their compact build, Dometic 310 toilets deliver a comfortable experience with thoughtfully contoured bowls and seating heights that feel natural to use. The gravity-flush system provides efficient flushing performance, reducing the need for multiple flushes and helping conserve water while keeping the bowl clean and odor-free.
Available Options
The 310 Series is available in multiple configurations to fit different RV setups. Typical options include high-profile and low-profile versions to align with varying bathroom ceiling and plumbing layouts. Color options often include white and bone/tan to match common RV interiors.

320 Series
The Dometic 320 Series RV toilets are a premium upgrade for RV owners seeking residential-style comfort, durability, and strong flushing performance.

Bowl Material & Build
The 320 Series features a ceramic (china) bowl paired with a durable RV-grade base. The ceramic surface is smooth, non-porous, and easy to clean, helping resist stains and odors better than plastic bowls. This construction provides a noticeably more residential look and feel.
Seat & Lid
Equipped with a full-size, residential-style seat and lid, the 320 Series prioritizes comfort. The seat feels sturdy and familiar, making it a popular choice for RVers who want a bathroom experience closer to home.
Weight
Because of the ceramic bowl, the 320 Series is heavier than plastic models like the 300 or 310 Series. While still designed for RV use, it’s best suited for owners who prioritize comfort over minimal weight savings.
Comfort & Feel
The 320 Series stands out for its home-like comfort and solid feel. The ceramic bowl, wider seating area, and well-designed bowl shape create a stable, comfortable experience ideal for daily or long-term use. The gravity-flush system delivers reliable, efficient flushing with minimal water.
