Best waterless toilet forResidential Houses

A domestic waterless toilet means you can often have a toilet in places where it might not be possible, practical or affordable to install anything else, for example under your stairs, within an extension or a loft conversion. Whether your interest is about being more eco-friendly (by reducing water consumption and nutrient loss), convenience, or simply the cost, there are a variety of compost toilets that work well in residential and domestic settings.

Modern compost toilets are a far cry from those smelly, horrible things you might have experienced at festivals – they look good, work well and control odours better than a “normal” WC! They can be installed and used as your primary toilet, or as a supplementary toilet in an extension, outhouse or ancillary building.

The compost toilet below are waterless, odourless and don’t need any connection to mains drains, sewers or septic systems.

 

Best domestic compost toilets for home use

Separett Villa Compost Toilet

4.8/5

With an unrivalled track record going back over twenty-five years, the Swedish-designed and manufactured Separett Villa is ideal for use in any dwelling for family use. It draws a tiny amount of electricity (< 2.5 watts) to run the small fan, which ensures it’s completely odour-free.

The Villa is a urine-diverting toilet, so the liquids are diverted away with only solid matter remaining in the toilet. And it’s so simple to use – just sit down, do your business and stand up – nothing to press, nothing to flush, no need for messy cover materials. A concealing flap covers the solids container from view – it opens automatically as the user sits down and closes again as they stand up.

The Villa has around 3-4 weeks of capacity for a couple of people using it full-time. Solids can be easily removed and safely composted away from the toilet and eventually returned to the land as compost or mulch.

Separett Tiny with Urine Extraction

4.6/5

Launched in 2021, the award-winning Separett Tiny has a contemporary and compact design that will fit neatly into smaller spaces. The vent pipe can be taken through the floor, wall or roof, giving you multiple options for installation.

Urine can be diverted away from the toilet into a soak-away pit or drain (like the Separett Villa), or there’s a version that has a built-in urine container that can be emptied as needed – ideal if you can’t run urine to a soak-away pit or drain.

The Tiny simply uses the efficient ventilation system for complete odour removal. An automatic concealing flap (improved and upgraded in May 2023) means you don’t see into the solids container when you lift the lid – the flap opens automatically as you sit down and closes as you stand up.

With a solid waste container capacity of 14.5 litres, the Tiny is best suited to less intensive use or as an additional toilet in your dwelling.

WooWoo GT LUX

4/5

If you have a void beneath the floor, you might be able to install the WooWoo GT LUX composting toilet, complete with a luxurious porcelain pedestal.

The WooWoo GT LUX is a full composting toilet, meaning that composting takes place within the containers. To support this, the starter pack comes with two containers - one in use and the other composting away. This means you’re only handling safe, sweet smelling compost!

The familiarity and luxury of a drop-through porcelain pedestal makes it simple to use for people of all ages and because it isn’t based on a urine diverter, there’s very little to go wrong which is great for users unfamiliar with composting toilets.

The electrical ventilation fan takes away excess moisture and all odours, making the toilet a pleasure to use.

Alectura composting toilet

0/5

New for 2025 is the Australian-designed Alectura by Nature Loo.

The standout feature is the stylish porcelain pedestal that looks at home in any setting, and because it doesn't have a urine-separator, it's easy to use by family and friends, and easy to clean. It looks so good, people won't realise it's a composting toilet until they try to flush it!

The Alectura Premium is a true composting toilet and comes with two under-floor collection and composting chambers that only need 50cm of clearance under the floor to work. Each container has a capacity of up to 90 litres, providing up to 6 months of capacity for a couple of people.

When the first container is full, use the included EZLift trolley to manoeuvre it out and swap in the empty container. Once a week, turn the handle on the side to mix and aerate the contents to level the contents and give the composting process a boost.
