Choosing the Best Marine Toilet for Your Vessel — A Complete Buying Guide

The market is highly saturated, and it gets confusing to choose the best marine toilet for your boat. After all, a marine toilet is an investment that would make or break your voyage. So, it is vital to conduct proper research before you make a purchase.

First off, a product like that of a portable toilet is highly subjective because its relevance varies from person to person. Some would consider a huge toilet while others would go for a small one. Therefore, get your facts straight before buying any portable toilet to avoid the hassle.

Types of Portable Toilets

There are three types of portable toilets available in the market, and each one of them offers different perks.

1. A Cartridge Toilet

Colloquially known as a cassette toilet is a semi-portable toilet, which is a permanent toilet with a portable tank that can be removed and dumped in dump stations. This type of toilet has three main parts:

1. The toilet: which is permanently secured to the boat.

2. The flush: which is installed on the bathroom wall above the toilet.

3. A waste tank: sits below the toilet.

If you spend most of your time in a boat, this would be the best choice for you as it provides the permanent solution with a portable water tank that can be carried away to dump stations.

2. Pump-Out Toilets

These toilets feature a ceramic bowl that gives such comfortable home vibes, and this is the reason why they are so popular among the masses. However, they can either be manual or electric. For the former, you have to clean and flush the toilet yourself with a few pulls from the lever. While the latter provides you with the ease of cleanliness and so you do not have to flush or clean the toilet and let the device do the magic!

If you hate cleaning the waste, go for an electric toilet. It is a bit costly than the manual but worth all the money. However, if cleaning and flushing do not bother you, stick to the manual one.

3. The Eco-Toilet

If you are a boating-cum nature enthusiast, the composting toilet would serve you the purpose.

The composting toilet is a successful sustainable take on toilets that are not using any water and turn your waste into fertilizer. It varies in size, however large as compared to the regular toilets.

Marine Toilets Material

Marine toilets come in various materials depending on your preferences. However, prices may vary depending on the cost of the material. Some toilets use high-quality ABS plastic that is durable and corrosion-resistant and would last for years. While others use low-quality, cheap material.

Here are the two most commonly used materials for portable marine heads:

1. Plastic: The marine toilets made of plastic are lightweight and sturdy as compared to porcelain. However, it might be difficult to clean them.

2. Porcelain: This material is heavy and looks much regal with a surface easy to clean than the plastic.

Marine Toilets Capacity

While choosing a portable toilet for your boat, keep in mind the usage and need for water. Different toilets offer various sizes of tanks that store gallons of water required for individual use.

Ease of Maintenance and Flushing Mechanism

Marine toilets are in frequent use, therefore, demand proper upkeep and maintenance. Always look for the marine toilet options that offer detachable and replaceable parts. Also, the flush mechanism plays a vital role in proper cleaning and flushing to fight against smell bacteria. It is best to choose a marine toilet with a powerful flushing mechanism.

Waste Level Indicator

It is the most important and underrated aspect of any marine toilet. The portable toilets that offer waste level indicator save us a lot of hassle.

No one likes accumulated, stinky waste to ruin their boating adventures, so watch out for the options that provide indicators to indicate when the tanks need to be refilled or emptied.

Size & Measurements

The size of marine toilets varies from company to company and model to model. Always measure the dimensions and compare the measurements of the toilet and check the available space in your boat before making a purchase. Some toilets are huge, while others would easily fit in small, enclosed spaces.

Leak-Free, Odor Free

The health and hygiene performance of your marine toilet should be exemplary. Especially in boats, where the toilet is kept in an enclosed area for long periods. There is nothing as horrible as odor wafting in and out of your toilet.

If you are an avid sailor and prioritize the health and hygiene of your family, always choose a toilet that specifies a sealed valve or offer mechanisms with deodorizer to bypass this issue.

Toilet Sounds

When you flush your toilets, there is usually a loud banging noise coming from the walls. Some people do not seem to have any problem with it, while others hate it.

If you are someone who cannot take the loud flush noise, look out for the options that provide noise-free flushing for smooth and convenient boating excursions.
