10 Best Cassette Toilet Rv 2026 in the United States

The SEAFLO Residential Height Camper/RV Toilet is designed to bring the comfort of home into your RV with its standard 18.5-inch height and an oversized, elongated bowl that helps with ease and cleanliness. Its dimensions (approximately 17.8” x 15.3” x 18.4”) make it compact enough for most camper spaces without feeling cramped. The gravity flush system uses tri-directional nozzles to deliver a strong, efficient flush. This type of flush is simple and reliable, though it relies on gravity and water volume, so it may not be as powerful as electric or pressure-assisted models. You operate it with a foot pedal, which adjusts water flow, making flushing hands-free and convenient. The bowl’s smooth, anti-stick surface reduces mess and splash-back, which makes cleaning easier—an important feature for RV use.

The seat has a soft-close mechanism, preventing loud slams during travel. Made from durable yet lightweight polypropylene plastic, the toilet balances sturdiness with portability, though plastic may feel less solid compared to porcelain. Installation is straightforward with included mounting bolts, but note that the floor flange is sold separately, so you’ll need to get that for a complete setup. Maintenance should be simple thanks to the design and materials, and the four-year warranty offers reassurance about durability. This toilet is well suited for RV owners wanting a reliable, comfortable, and easy-to-clean option without complex plumbing or electric parts. If you need a more powerful flush or integrated waste tank, you might want to explore other models.

The Dometic 320 Series Standard Height Gravity RV Toilet is designed with comfort and functionality in mind. Its elongated ceramic bowl provides a more comfortable seating experience compared to traditional RV toilets, while the enameled wood seat adds a touch of quality and warmth. One of its standout features is the pressurized full-rim flush system, which ensures a thorough cleaning with every use—a significant advantage for maintaining hygiene in a confined space like an RV.

This toilet’s deep 100% vitreous ceramic bowl is not only durable but also easy to clean, which is important for RV owners who value maintenance simplicity. The ergonomic foot pedal flush system is another plus, allowing for easy operation without needing to touch any surfaces, which is beneficial in terms of hygiene.

However, there are a few considerations to keep in mind. Weighing in at 43 pounds, this toilet is relatively heavy compared to some other models, which might make installation a bit more challenging, especially for those who prefer a lighter option. Additionally, while the dimensions of 22"D x 14.75"W x 19.75"H fit standard spaces well, it may not be ideal for smaller RV bathrooms where space is a premium. In terms of installation and maintenance, this model is floor-mounted, which is standard for RV toilets, but ensures that users may need to plan for a more involved installation process. The build quality is solid, but as with any ceramic fixture, care must be taken to avoid chips or cracks, which can occur during travel.

The Dometic 310 Standard Toilet is designed specifically for RVs, making it a solid choice for those looking for a reliable and efficient toilet system. One of its standout features is the pressure-enhanced 'PowerFlush' mechanism, which allows for effective cleaning of the bowl using very little water—only about a pint per flush. This water efficiency is a significant plus for RV users, who often have limited water supply. Additionally, the lightweight design and universal fit make installation straightforward for most RV setups.

User comfort is another priority with this toilet. The ergonomic seat height and oblong bowl shape ensure that it’s comfortable to use, while the slow-close seat cover minimizes noise and potential damage from slamming.

However, the Dometic 310 has a few considerations to keep in mind. At 41 pounds, it may be heavier than some other portable options, which could be a downside for users prioritizing weight. Although ceramic construction adds durability, it can also make the toilet more prone to cracking if not handled carefully during installation or transport. Furthermore, while the toilet is designed for ease of operation, some users may still find the learning curve a bit steep if they are unfamiliar with RV toilets.
