£420.00 inc. VAT

The brand new 2019 Eco-Loo Capture is here now. Built to order in around 7 days, it’s the ideal urine diverting, waterless compost toilet for mobile and off-grid installations! Give us a call to order or to get more information!

A self-contained, urine-separating compost toilet where space is tight or when portability is important. At 400mm wide, it can go almost anywhere and is ideal for mobile users on narrowboats, barges, campervans, motor caravans, caravans, boats or dwellings where you are unable to run urine into a soak-pit.


The new 2019 Eco-Loo Capture replaces both the previous Eco-Loo Capture and Mini Capture

The Eco-Loo Capture is a self-contained, urine-diverting, waterless compost toilet designed for off-grid mobile installations on boats, camper vans, caravan etc, or in land-based situations where you can’t run urine into a soak-away pit.

By separating liquids from solids (wee from poo), it makes management of the toilet simple and straightforward.

Particularly suited to mobile installations where there is water or drainage facilities, such as narrowboats, barges, caravans, camper vans, garden huts etc.

The elegant design, automatically diverts urine into the easily removable 10 litre urine bottle. Solids drop through into the inner container, where you cover with some wood shavings (and/or use the optional fan for complete odour and moisture control) for odour control. When the solids container is full, it can be emptied onto a compost bin for safe decomposition for twelve months or more.

It’s simple, elegant and it just works! The base has a moulded plastic sheet which means any stray liquid won’t soak into the wood or leak onto the floor.

About the Eco-Loo Capture compost toilet – 2019 design.

After five years of essentially the same design (albeit with some dimension and material changes), we found ourselves unable to cope with the demand due to the complex and hand-made nature of the manufacture of the original Eco-Loo Capture. The best way to speed up production whilst maintaining the quality, simplicity and functionality of the previous models was to create the toilet box from CNC cut birch plywood.

We’ve built in loads of features and options (some not available just yet…) that means this off-grid compost toilet is:

  • Modular
  • Expandable
  • Adaptable
  • Beautiful!

As before, it’s based around a high quality fibre-glass urine separator, a 10 litre urine bottle and a 23 litre ‘solids’ container. All of these items have SteriTouch, an anti-bacterial agent built in. The solids container comes with a lid, has built in grab handles and is stackable (if you wish to store several before emptying). The square shape provides the maximum capacity for the space taken up. The urine container has a carry handle, and wide opening to prevent ‘glugging’ and to facilitate easy cleaning.

The toilet seat and lid is ‘standard’ close, and is solid oak that looks beautiful.

The toilet box is made from engineered and precision CNC cut 15mm birch plywood. Birch is a relatively dense wood that gives a very smooth surface for painting or staining and is very tough. We’ve also fitted some feet on the bottom so it stands very slightly off the floor, which will help protect the toilet.

We now also offer the option of having the front and sides ‘fluted’ to look like the previous ‘tongue and groove’ design for that classic rustic look! This is available at NO EXTRA CHARGE.

The Eco-Loo Capture comes with pre cut holes for the optional fan (blanking plates are supplied when the fan is not fitted). In the base, a specially moulded plastic tray ensures all the containers fit in the right place, and any spillages are contained and won’t get to the wood. The tray holds up to 1 litre.


  • Size: 400mm (max. width) x 525mm (front to back) x 460mm (height to seat)
  • Solids Tank Capacity: 23 litres – antibacterial
  • Urine Tank Capacity: 10 litres antibacterial.
  • ‘Overflow’ Capacity using base tray: 1 litre.
  • Solid Oak standard toilet seat (optional plastic soft close)
  • 15mm birch plywood construction – sides, top and base
  • Kick trim around base


The optional 12 volt fan provides continuous ventilation and is ideal when you either want to use less cover material or in a holiday let situation where guests might be new to compost toilets. The fan connects to standard 50mm rigid pipework (again, available from DIY stores and builders merchants) and can vent outside where odours will dissipate rapidly. Alternatively, you can just use a cover material such as wood shavings.

We can also supply a 230 volt AC to 12 volt DC adaptor where mains power is available, however the fan draws very little power and can easily be run from a solar panel and battery.

You can purchase the Eco-Loo Capture unpainted, so you can paint, stain, varnish, or oil it yourself, or we can optionally paint it for you. We now use professional ‘2-part’ paint and lacquer by Morrells which is colour matched to the previous Farrow & Ball colours we used (All White®, Blue Ground®, Calke Green®, Stiffkey Blue® and Downpipe Grey®) – the advantage being these finishes are incredibly tough and hard wearing. The sheen level is 40%, equivalent to ‘satinwood’. Other colours are available, so if you’re after a particular one, please get in touch.

2019 Eco-Loo Colours

Future Proof and Adaptable

As we have unified the design between the Divert and Capture, it’s now possible to buy one model and convert to the other! This gives you maximum freedom particularly if you know that your needs might change in the future.

Other fan and ventilation options means that you’ll be able to use the Eco-Loo almost anywhere. There’s also some other options that we’re not launching just yet, but the facility for them is built into the new 2019 Eco-Loo right now, making it highly adaptable.


Because of the new manufacturing methods, we can usually manufacture your Eco-Loo in around 7 working days, and around 14 days for a painted/lacquered one. No more 6-8 week waiting lists!

How to use it?

Just put it in place and start using it. Most people start just using wood shavings for the cover material.

The urine bottle should ideally be emptied daily to help prevent scaling etc, although it will provide at least 2 – 3 days capacity for a couple of people if needed. You can empty the urine into an Elsan point, grey water drain, or around tress or bushes away from a water course (urine should NEVER be emptied into a watercourse or canal).

The solids container will need emptying every so often (we expect it to last around 3 weeks for a couple of people) – assuming you have used biodegradable liners, just open the top of the toilet, tie up the liner and put the lid on the container – this can be be lifted out and the contents put into your compost bin. For details on composting, click here. Alternatively, if you cannot compost, you can bag and bin the contents of the solids container, but you must use the appropriately labelled bags and should always double-bag. We always recommend composting rather than binning, but we accept not everyone can do this all the time.
