Where people use Pi-Pi urinals and sinks
A garden shed or allotment, an off-grid cabin or summerhouse, a campervan or narrowboat – and especially alongside a composting or separating toilet, where Pi-Pi takes the liquid so the container fills far more slowly.
Choose a model for the garden
In both models, liquid drains through the bottom outlet into your container. The practical difference between the models is in the top port.

Waterless urinal and garden sink for allotment sheds and garden plots
A wall-mounted waterless urinal and an outdoor sink for the allotment shed, summer house or garden cabin – no plumbing needed, and a separating toilet fills more slowly alongside it.

Waterless urinal and outdoor sink for cabins, smallholdings and summerhouses
Wall-mounted waterless urinal and outdoor sink for off-grid cabins, smallholdings and summerhouses – the dry toilet fills slower and there is no water line to run.

Caravan sink and waterless urinal that fit a thin van partition
Wall-mounted waterless urinal for campervans, motorhomes, and campers. Urine goes into a separate container, so less liquid enters the cassette toilet or separating toilet, and it fills up more slowly.

Urinal for your composting toilet: Trelino, BOXIO, Kildwick, Separett
Wall-mounted waterless urinal for owners of a separating composting toilet – the liquid container overflows less often and the composting chamber stays dry.

Sink for Garage and Workshop
Durable plastic sink for garages, workshops, and utility rooms – for places where you need to wash your hands but there is no tap on the wall. Mounts on the wall, with drainage into a bucket, canister, or pipe, and is unaffected by freezing temperatures in unheated spaces.

Waterless urinal and camping sink for campsites, caravan parks and glamping
A waterless urinal and a camping sink for small campsites, caravan and holiday parks and glamping pitches – no water supply to lay on, and a composting toilet fills more slowly beside it.
