Marine composting toilets

Marine toilets are known as heads, as they were positioned in the ‘head’ of the ship. That’s how our Nature’s Head® toilets got their name, as they were designed by two sailors looking for a more user-friendly toilet for marine use than was available at the time. They designed their marine composting toilet to withstand the harsh marine environment, and also to eliminate the need for expensive pumping of black water waste at marinas.

Shop now for a composting toilet for your boat, cabin cruiser, houseboat, catamaran, pontoon boat, yacht, ferry, larger fishing boat, pleasure cruiser, tour boat, river boat, barge, narrowboat or any marine craft where you might want a toilet! Our Nature’s Head® even features a curved back to enable easy fitting in marine craft.

Why use a composting toilet as a marine toilet

In a marine environment, life is literally never still. Your boat will be gently rocking even when moored, and in adverse conditions, it’ll be rocking and rolling. So will the content of any water-based toilet you have on board….

That increases the opportunities for liquids to leak, whether waste or toilet chemicals (or both). Waste water will also need to be stored in a tank which will need emptying on arrival in port. The results is a toilet system that will inevitably smell and slosh about, not ideal!

The no-smell solution for marine toilets

A composting toilet uses no water, so there is no smelly liquid waste to slosh about, no nasty chemicals to add, and no black waste to store or pump out of a tank. Indeed, many marinas won’t accept black waste that includes certain chemicals, which can be a major issue.

Instead, you have just two elements:

  • A storage bottle for urine which can safely be disposed of overboard. This is permitted in the UK, without harming the marine environment.
  • The solid waste converts to environmentally-friendly and clean-smelling compost, which can be disposed of in a bag in any regular waste bin on shore.

Robust, high capacity, simple to use

When you’re at sea, you haven’t time to worry about your toilet! The Nature’s Head marine toilet is a simple integrated unit that’s robust, and easy to secure in place.

  • The integrated seat ensures there’s no toilet seat to flap about.
  • The urine bottle is securely held in place yet easy to remove when required.

Sewage disposal at sea

Whilst in the UK it is acceptable to dump the contents of marine toilets at sea, there are issues for those concerned with protecting the marine environment.

Urine is 95% water with sodium and chlorine ions, so it’s very close to seawater in composition. However, it also contains urea and possibly trace elements of drugs such as hormones. The general consensus is that so long as you dispose of urine out at sea where water circulates, the effect will be minimal, as this article and associated video explains:

Solid waste, however is a different matter. The less of it we put into our lakes, rivers and oceans, the better. With a capacity of up to 80 uses, the solid waste section in a composting toilet will last for significantly long periods at sea, far longer than the average trip by boat, yacht, motor cruiser or pleasure craft.
