Two Bog Standard composting toilets in one compact building — the Twin Composting Toilet is the practical answer for sites where one toilet isn't enough. Campsites, festivals, allotment sites, community gardens, forest schools: anywhere footfall is high enough to need two cubicles without the footprint of two separate buildings. Side by side, handmade in Wales, and built to the same standard as every toilet in our range.
The twin format doubles capacity without doubling the space. Both cubicles share one building structure, each with its own urine separator, wheelie bin system, and door — independent, hygienic, and odour-free. No water, no electricity, no drainage infrastructure needed.
Two Size Options
-
Reduced-height — 200-litre wheelie bins, lower building, one step per door
-
Full-height — 240-litre wheelie bins, taller building, three steps per door
Key Features
-
Double capacity, single footprint — two fully independent cubicles in one compact structure. Ideal for higher-footfall campsites, allotments, and events.
-
Odour-free by design — each cubicle has its own urine separator, keeping liquid and solid waste apart and eliminating smell entirely.
-
Wheelie bin waste system — easy, hygienic emptying. No digging, no mess.
-
No water or electricity — completely off-grid and self-contained.
-
Handmade in Wales — built by our team from quality timber, not a factory kit.

Delivery
Your compost toilet is delivered flat-pack on an oversized pallet by a national pallet courier, which is both cost-effective and included in the price.
Delivery is curbside — the driver will bring the pallet to the nearest point accessible by road, but won't cross fields or soft ground. Because the pallet is oversized, it can't be lowered on a tail lift and needs to be taken from the side of the lorry.
If you have access to a forklift or tractor, that's ideal — you can fork the pallet straight off and move it directly to your installation spot. If not, no problem at all: just have two people available on the day to help handball the panels down from the lorry. It's straightforward, and many of our customers manage without any machinery.
If you'd prefer a personal delivery and installation service, please get in touch to discuss.
