10 Best Marine Toilets 2025 in the United States

The SANIFLO Saniaccess 2 + Toilet Bowl Elongated + Toilet Tank Bundle is a comprehensive package designed to meet the needs of those upgrading their bathroom, especially in residential settings. One of its standout features is its dual-purpose functionality, allowing it to discharge gray water from a sink, which adds versatility to its use.

The product is relatively large, with dimensions of 27"D x 17.75"W x 31"H, so it may not be suitable for smaller marine environments but fits well in a medium to large-sized space. The plastic material ensures durability and reduces the risk of corrosion in a moist environment. The flushing mechanism includes a macerating pump with a 0.5 HP motor, which promises efficient waste processing but might be slightly noisy with a noise level of ≤ 53 dBA.

The ease of maintenance is a significant plus, thanks to the two easy-access service panels that simplify electrical and mechanical troubleshooting. The installation process is straightforward due to the rear outlet design, but the total weight of 111 pounds might require two people to handle. The four-year warranty offers peace of mind and indicates the manufacturer’s confidence in product longevity. While the product is well-rated (4.2 out of 5 stars from 373 reviews), it may not be the best fit for small or highly compact spaces. Users looking for a reliable, multi-functional, and easy-to-maintain marine toilet will find this bundle an excellent choice.

The Dometic 302320081 320 Series Standard Height RV Toilet is designed with a full-size residential style wood seat and a deep vitreous ceramic bowl, offering durability and a comfortable experience. With dimensions of 22 inches deep, 14.75 inches wide, and 19.75 inches high, this toilet fits well in various spaces while maintaining a standard height for user convenience. One of its standout features is the efficient water usage, requiring only one pint per flush, which is beneficial for conserving water on a boat or RV.

The ergonomic foot pedal is intuitive, allowing users to add water by partially pressing it or to flush fully by pressing it completely. The gravity flush system is simple and effective, but it may not be as powerful as other types of flush mechanisms. The rim design helps prevent spills, adding to its practicality. On the downside, the 43-pound weight might make installation a bit challenging, especially for individuals without assistance. Additionally, while the toilet does not come with a holding tank, this means you will need to ensure compatibility with your existing tank or purchase one separately.

Maintenance-wise, the ceramic bowl is easy to clean, though the wooden seat may require some extra care to maintain its condition over time. This product is ideal for those seeking a durable, comfortable, and water-efficient marine or RV toilet with a residential feel.

The Dometic 310 Standard Toilet is designed to be a practical choice for modern RVs. It is full-sized yet lightweight, making it easy to install and handle. Its oblong shape ensures a comfortable seating experience while fitting well in various RV layouts. The innovative PowerFlush system stands out by efficiently clearing the bowl with minimal water usage, highlighting its water efficiency.

The slow-close seat cover adds a touch of modern convenience, preventing slamming and reducing wear and tear over time. One of its major strengths is its ease of installation and maintenance, thanks to its simplified design and universal fit. Users can expect durability from its construction, combining wood, ceramic, and plastic materials.

The pressure-enhanced flushing mechanism is excellent for efficiency but may require proper maintenance to keep it functioning optimally. The one-direction pedal operation is user-friendly, but some might prefer more advanced features for ease of use. The Dometic 310 toilet is a well-rounded option for those seeking comfort, efficiency, and easy installation in their RVs.
