Best Boat Toilet – Our Top 5 Picks
Best Marine Toilet Buyer’s Guide
The different types of boat toilet
There are a number of types of marine toilet that you can opt for depending on your needs, budget and preference.
Let’s take a closer look at what they are.
Best electric marine toilet
First up is the popular electrical marine toilet. There is a wide range of products available in this category, the prevailing difference being the type of pump used.
The entry-level electric boat toilet (and therefore the cheapest) generally use pumps that feature a combined chopper and impeller. The problem with these is that they are very noisy to operate, (an issue that can cause embarrassment for guests).
Because of the inbuilt electric pump system, these toilets can be installed above or below the waterline.
Other advantages include the convenience of the electric operation, (you do not need to manually pump to flush the toilet) and the fact they are so simple to use.
Furthermore, if the toilet includes a macerator there is less chance of refuse clogging the lines.
From a negative perspective, electric marine toilets cost more and are more difficult to install.
Manual boat toilets
Most manual head marine toilets utilize a hand or foot pump system to dispose of the waste.
The great thing about manual toilets is the fact they are cheap, relatively easy to install, (no need for power lines) and reliable.
They generally give off more odors however, as the manual pump flushing system clears less efficiently than the electric models.
Portable boat toilets
It could be that you’re on the lookout for the best marine portable toilet.
There are a few benefits to the ‘porta-potty’. The number one reason to opt for a portable toilet for your boat is affordability and convenience.
They do not need to be permanently installed as the waste is simply collected in an inbuilt tank beneath the unit. You can empty this waste at any sewage collection point once you have moored.
You do have to consider the fact that freshwater (10 or 20 liters) has to be added for flushing, (and obviously needs to be refilled as often as required). You also have to carry the necessary chemicals onboard.
Finally, there is a composting toilet. This is becoming a very popular choice for boat owners (and beyond as they suit any type of mobile convenience application).
So what goes into making the best composting toilet for boats? Odorless operation and ecological friendliness are the two biggest considerations.
Boat owners love the fact composting toilets very rarely smell. There is no need for hazardous chemicals and they do not cause pollution.
This type of toilet uses two receptacles, (one for number one, the other for number twos).
The composting toilet works by allowing oxygen to dry and compost the waste. Peat moss or sawdust is added to the waste to speed up the decomposition as well as cover any smells.
The whole system is very reliable and needs little maintenance. They are also the best waterless toilet as there is no need for water and the waste can be safely disposed off.
An issue that may put people off the composting marine toilet is the fact they are taller than other types. In fact, if space is limited you may not be able to fit one into your boat.
They are also more expensive to buy.

What to look for when buying a marine toilet
If you remain uncertain about the type of boat toilet you wish to buy, you may want to consider the following issues in order to narrow down your choice.
These are just a few areas you should consider before you buy.
It goes without saying that you should never dump your waste overboard. However, the level of eco-friendliness each toilet has does vary.
The best electric marine toilets will include a macerator pump. This will grind up the solid waste before it is disposed into the holding tank.
Not only does this increase the amount of refuse you can store, but it also helps speed up decomposing once the waste is fully disposed of.
As we mentioned above – nothing beats the compost toilet for eco-friendliness. Yes, they cost more, however, if you really care about the environment and wish to lessen your impact on it, there is no better choice. They also smell a lot better too.
When buying a marine toilet you should definitely consider the materials the unit is made from.
A porcelain bowl is stronger, easier to clean and more familiar than a plastic model. However, they are more expensive.
Most portable toilets opt for plastic construction because weight is clearly important, as is the price point.
If your boat utilizes a saltwater system the macerator mechanism should be constructed from stainless steel or bronze.
Likewise, you will need anti-corrosive materials used on trimmings and fasteners – especially if your toilet area doubles up as a shower.
Footprint & Hook Up (access points)
You should also consider the footprint of the toilet and the space you have available. That goes for height too in the case of potential composting toilet installation.
The toilet needs to fit your headspace. Serviceable areas also need to be reached once the toilet is in place.
There is also the issue of installation and hook up. How will you link the toilet up to the power if you have chosen an electrical model? Is the wiring up to the current draw of the motor?
You need to think about the raw-water intake and overboard discharge. These need to be located on opposite sides of the keel if possible.
Again, the composting toilet wins on this. Not only will your decomposing waste be odor-free, but you will also be able to use it as fertilizer for the garden.
Vacuum-flush systems (available on some electric and manual models) are also good at tackling nasty odors.
They utilize on-board fresh water to flush, (which is one issue to consider). However, the system is cleaner and helps eradicate odor by washing away bad-smelling bacteria.
Finally, there is an issue of noise. Cheap electric toilets and manual units are generally the loudest when operated. Those pumps and macerators will make a din.
However, more expensive models do attempt to quieten the mechanisms by design. And if you prefer to perform your morning ablutions without waking everyone else onboard, a quiet toilet may well be worth the asking price.
