Things to consider before buying a Marine Toilet

Marine toilets are different from our conventional toilets. The use and situation are different. It would be best if you considered a few things before inventing a marine toilet.

Here are some factors that you should keep in mind while buying a marine toilet:

Types of Toilet

There are different types of toilets available for boats. Depending on the type and price range, they offer you various services.

Price also plays a significant factor. Depending on the amount, you will choose the right one that is suitable for you.

There are different types of marine toilets:

Cassette Toilet:

These toilets are similar to the toilets for RVs. This type of toilets is portable. You can easily set up this in your boat.

For the mobilization, it can be put into smooth corners of the bathroom. Cassette holds the wastage, and when it is full, you can dump the wastage. One problem is, you have to carry the wastage by yourself while clearing out everything.

Pump-out Toilets:

These are better for long-term use. If you want something permanent and can be used for a long time, try this design type.

They can have a different plan like manual and electric. For the manual ones, you need to pull the flush that is placed on the side. For the electric ones, you will get a pump set in the toilet that takes care of the wastage.

Composting Toilets:

These are eco-friendly. They do not use water; rather, they separate the liquid from solid wastage. The urine goes in a separate chamber that you have to dump.

The solid waste goes into another composting room. The chamber completely degrades the wastage. These types of toilets are a bit larger. So, keep that in mind while you place the toilet in the bathroom. 


Keep in mind you can not just dump the wastage on water. The chemical you use for marine toilets should be safe for the environment. There are some rules that you must obey.

Also, use bio-degradable papers. It also prevents your toilet pipes from clogging. The composting toilets are more prevalent among people.


Because of the harsh environment, a marine toilet should have a durable and robust build. It can be exposed to saltwater, so these types of toilets are durable.

To avoid corrosion, the hardware should be built with stainless steel. Other than steel, high-quality plastics also works well.

Plastic toilets are lightweight so that they can be easily moved. Porcelain toilets are heavy. They are too difficult to install.


If the marine toilet you got is portable, then you don’t have to worry about it. You can set it up anywhere. But is you are using a non-portable one, then inspect the space where you will set up. You might need to drill some holes. Be sure to link a freshwater pipe near the toilet.


This is a primary concern. No one wants to smell in the boat. When you buy a marine toilet, make sure it has a valve that prevents the wastage from re-entering the bowl. In this way, you won’t get any bad smell.

There are toilets with special deodorized flush water that helps to reduce bad odor. Also, leaking can be a more significant issue. Make sure your bathroom is made with durable, leak-proof material.


The flushing in marine toilets can be noisy. There are modern designs that produce minimum sound. Make sure your toilet has those features. Otherwise, it can be not very pleasant.
