10 Best Marine Toilets 2026 in the United States

The Saniflo Sanicompact is a one-piece, floor-mounted macerating toilet designed primarily for small spaces like half bathrooms or basements. Its compact size (21.5" deep, 14.5" wide, and 18.5" high) makes it a good fit where space is tight. The built-in pump and macerating system allow the toilet to handle black and gray water efficiently, pushing waste up to 9 feet vertically or up to 120 feet horizontally, which is ideal for installations far from the main drain.

It uses a dual-flush system that saves water, which is helpful if you want to reduce water usage. The toilet operates quietly at 53 dBa, so it won’t cause much noise disruption. Installation is relatively straightforward since it’s an all-in-one unit with floor mount, suitable for DIY or professional setup. However, it doesn’t have a traditional holding tank since it macerates and pumps waste directly into your plumbing, so it’s not the best choice if you need a large holding tank capacity. Maintenance is generally easy, but like all macerating toilets, occasional servicing of the pump may be needed.

The toilet’s sturdy plastic seat and white finish fit most bathrooms, and it comes with a 4-year limited warranty, adding peace of mind. This model is a solid option if you need a space-saving, water-efficient toilet that can be installed away from normal plumbing lines. However, it might not suit those who prefer a standard gravity-flush toilet or require a large holding tank.

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 Raritan Sea Era Marine Size Electric Toilet is a floor-mounted, electric marine toilet designed for boat bathrooms. It measures 24 by 23 by 17 inches and weighs 35 pounds, which is a moderate size and weight suitable for many marine vessels that need a compact yet sturdy toilet option. Made of durable plastic with a polypropylene seat, it promises good resistance to the marine environment and easy cleaning.

The electric flush system includes an integral pump and accommodates both straight and 90-degree discharge, giving some flexibility in installation depending on your boat’s plumbing layout. Installation should be straightforward for those familiar with marine plumbing, but because it’s floor-mounted and includes electrical components, some users might want professional help to ensure proper setup and maintenance. Customer ratings are very positive, reflecting good satisfaction with performance and reliability.

This Raritan Sea Era model suits boat owners looking for a reliable, electric marine toilet with flexible discharge options, offering solid build quality and decent size without being overly complex.
