The Double Disabled Access Compost Toilet Block is our most comprehensive accessible toilet building — two wheelchair accessible composting toilet cubicles with a central handwashing area, built to statutory DDA dimensions, waterless, off-grid and handcrafted in Wales.
It is designed for busy public places that take inclusion seriously: visitor centres, nature reserves, country parks, National Trust and heritage sites, council-run open spaces, campsites, holiday parks and accessible glamping sites, schools and outdoor education centres, Scout camps and community gardens. All of them face the same problem — providing proper toilets for disabled visitors where connecting to mains drainage is impossible or prohibitively expensive. Our waterless composting system solves it entirely: no sewer connection, no chemicals, no smell and no harm to the surrounding environment.
We have been building composting toilets in Wales for over 20 years, with more than 500 toilet buildings made and installed across the UK. Our view has always been function first, but form matters — the more beautiful the toilet, the more people accept it, and the better a site looks after it. Each cubicle uses a urine-separating seat that keeps it free of smell (guaranteed) and is as easy to use as a normal loo. We build with quality, oversized timbers and take no shortcuts; we are not the cheapest, but we stand by every building that leaves our workshop. Our recent accessible toilet blocks have gone to an independent school nursery in Perthshire and a charity's outdoor site in Kent.
Who It's For
-
Visitor centres, nature reserves, National Trust and heritage sites — high-footfall, high-visibility public settings, including SSSIs and sites where groundwater protection is a priority.
-
Councils, country parks and public open spaces — a permanent accessible toilet block without drainage works.
-
Campsites, holiday parks and accessible glamping sites — two accessible, off-grid toilets plus handwashing in one building.
-
Schools, nurseries, outdoor education centres and Scout camps — one Scout group told us our compost toilets have "transformed our Scout Camps. No more Porta Loos."
-
Community gardens, allotment sites, charities and land trusts — often funded through grants (see below).

Key Features
-
Full DDA-compliant wheelchair access — both cubicles are built to statutory wheelchair accessible dimensions with turning space, grab rails and a level-access entrance.
-
Central handwashing area — a shared facility between the two cubicles, with natural light, that maximises space without compromising accessibility. Tell us how you will use it: we can fit one large, deep sink (handy for washing up and filling urns) or two smaller basins.
-
Waterless composting system — each cubicle has a urine-separating seat and a 240-litre wheelie bin. Separated urine goes to a soakaway or collection vessel; solids compost in the bin over approximately 12 months before use as a soil amendment.
-
Chemical-free and odour-free — integrated ventilation and urine separation keep the block fresh, making it suitable for sensitive sites.
-
Built around your project — dimensions, access ramp gradient, cladding, colour, internal fittings and integration with an existing building can all be tailored.

Grant Funding
Disabled access composting toilet buildings like this one are routinely funded through public and charitable grant programmes. If you are a community organisation, charity, land trust or public body, you may be able to cover much of the cost through grant funding rather than capital budgets. Funding sources that have supported projects like this include the National Lottery Community Fund, Groundwork UK, the Rural England Prosperity Fund, the UK Shared Prosperity Fund, Natural England stewardship schemes and local authority accessibility improvement grants. We are happy to support your application with a formal quotation, technical specifications and letters of support — contact us to discuss your project.
Ordering & Delivery
- We agree the design with you and send a drawing to approve
- A 50% deposit confirms your place in the workshop queue

Schools, councils and public bodies can order on a purchase order. Prices include VAT.
Due to its size, delivery of this building is not included in the product price. Delivery costs vary depending on your location and installation site — please get in touch for a quote. In most cases we carry out the installation as well as the delivery, travelling to site to build and install the structure for you. If you have sufficient manpower within your own team to handle installation, that is also an option. Ask us for current lead times, especially if you are working to a funding or opening deadline.
