Waterless urinal and outdoor sink for cabins, smallholdings and summerhouses

Wall-mounted waterless urinal for an off-grid home, farmstead, summer cabin, shepherd’s wagon, and small farm. Attaches to any wall, urine drains separately into a canister or connects to a dry toilet. No plumbing, no sewer connection.

The Pi-Pi sink hangs next to it: you supply the water yourself and the waste runs through a hose into a bucket or canister – there is no built-in tank and no pump.

Why an off-grid home needs a separate urinal

In a remote home, there is no plumbing or sewer system, and in winter any water pipe risks freezing. A dry or separation toilet (Separett, Biolan, Kildwick, Trelino) handles feces well, but its liquid waste container fills quickly and requires frequent emptying – especially if several people live or stay in the house.

Pi-Pi solves one specific part of the task: separate collection of urine by men standing, against the wall, without water. Less liquid enters the toilet: the container fills more slowly, and the contents remain drier.

Technical facts

  • Material LLDPE: does not crack at −40 °C; operating range −40…+60 °C, unheated house in winter is not a problem
  • Weight 1.4–1.5 kg: mounts on any wall, including thin wooden partitions and wagon walls
  • Installation 5–7 minutes: no plumber, no special tools required
  • Stepped nozzle Ø24/32/40 mm: fits garden hose and outlets of Separett, Biolan, Kildwick, Trelino without adapters
  • Standard: closed top, for installation without ventilation
  • Standard Plus: top opening Ø70 mm for connection to existing ventilation of the dry toilet
  • Manufactured in Estonia (EU)

What to do with collected urine

  • Garden fertiliser: some gardeners use diluted urine as a fertilizer; follow the dilution rules and proportions from official or professional recommendations in your region and plot regulations
  • For disposal: canister is emptied into a cesspit or disposed of according to local rules

Pi-Pi complements your dry toilet – it doesn’t replace it

In an off-grid cabin, on a smallholding or in a summerhouse, a dry or separating toilet handles most of the job, but its liquid container needs emptying often. Pi-Pi is a separate wall urinal: men use it standing, and the liquid drains straight into a jerrycan or the existing vent. There’s no water line to run, nothing to freeze in a pipe, and the dry toilet handles only solids.

  • Separett, Biolan: fixed-install units for an off-grid cabin – the Standard bottom outlet to a holding tank, the Ø70 mm top inlet on Standard Plus into the existing vent
  • Kildwick, Trelino: drain into a jerrycan or compost chamber, vent through Ø70 mm without an adapter
  • Soakaway or compost: Pi-Pi connects via its stepped outlet to any gravity-fed run

Seamless connection: the stepped outlet Ø24/32/40 mm meets the run already there, and the Ø70 mm top inlet on Standard Plus meets the existing ventilation duct without an adapter.

Frequently asked questions

Urine flows by gravity through an outlet into a closed container or dry toilet tank: no water, pump, or electricity needed. The urinal is wall-mounted, and a hose leads down to the container.
Read full answer
Yes, the Pi-Pi urinal can be left on the wall for the winter: the material does not crack in frost down to −40 °C. Before the frost, drain the canister and remove the hose to ensure no liquid remains in the drain line.

Water drains passively through an outlet Ø24/32/40 mm into a bucket or canister under the sink or via a hose to wherever you direct it. The Pi-Pi sink has no built-in tank or pump; you supply the water yourself.
Read full answer
With a closed container and a clean hose, the Pi-Pi waterless urinal does not smell: urine immediately goes into the container. In an enclosed space, ventilation through a Ø70 mm port helps. If an odor does appear, check the hose, container, and filter screen.
