Pi-Pi vs Agande
Two European makers of waterless urinals for the garden shed. Different materials, different lifespans, different behaviour in winter. Below — just the facts.
The purchase price is only part of the sum
Pi-Pi is slightly more expensive at purchase. However, unfilled polypropylene (PP) becomes brittle at around 0 °C, and its typical lifespan is 3–5 years. LLDPE from Pi-Pi withstands −40 °C and lasts 7–10 years — and in an unheated cabin that stays cold all winter, this is exactly where it matters. Order a sample and compare the material in person before making a decision.
Feature Comparison
 | Agande | |
|---|---|---|
Frost resistance Overwintering in an unheated shed | impact-resistant down to −40 °C | PP is brittle at around 0 °C |
Connect to a jerrycan or hose Outlet diameter | 24 / 32 / 40 mm — fits without adapters | Only 40 mm |
Lifespan Buy once instead of replacing often | 7–10 years | ~3–5 years |
Impact resistance Drops during fitting and transport | LLDPE absorbs knocks and won't crack | PP cracks under a knock |
Odour in summer Ventilation in a closed shed in the heat | Vent port 70 mm (Standard Plus) | No vent connection |
Data on Agande verified as of May 1, 2026 from public sources (agande.eu, agande.de, Amazon.de). Frost resistance and lifespan characteristics of PP are based on published materials science data for unfilled polypropylene under impact conditions at low temperatures. Prices, specifications, and availability are subject to change — check the manufacturer's website for current information.
Why this matters in the garden
The shed sits cold all winter — PP can't take it
Unfilled polypropylene (PP) becomes brittle at around 0 °C — right at the glass transition point, and this is a documented property of the material, not an isolated defect. In an unheated cabin or a house without plumbing in winter, the temperature drops much lower, and in spring you find a cracked urinal. LLDPE from Pi-Pi remains impact-resistant and flexible down to −40 °C — it survives the winter and greets the next spring without a single crack.
Buy once, instead of replacing it every few years
The price difference at the till looks noticeable at first. Over the years it flips: a PP urinal will likely need replacing twice in the time a Pi-Pi keeps going — each time meaning a new order, a new fit and disposing of the old one. With a 7–10 year life you buy Pi-Pi once for the shed and forget about it. The colder the winter and the rougher the use, the more clearly the tougher material pays off.
Direct from the maker, no middleman
Pi-Pi comes to your door straight from the EU maker in Estonia — no wholesaler in between adding a markup. You order online and we ship from stock. If you'd like to feel the material and check the finish in your own hands before you buy for the shed, we'll send a sample first.
Pairs with any composting or separating toilet
Pi-Pi is the missing companion to your composting or separating toilet — alongside Trelino, BOXIO, Kildwick or Separett, not instead of them. The urinal catches the liquid separately, so the solids container stays drier, fills two to three times slower and doesn't smell. The stepped outlet (24 / 32 / 40 mm) connects to a small jerrycan or a hose run outside — no plumbing and no water supply needed.

Pi-Pi Standard
Closed-top body — the simplest way to add a standing urinal to a shed or cabin that doesn't need a vent.
Pi-Pi Standard Plus
A Ø70 mm port on top ties straight into your composting toilet's existing vent — for an enclosed shed, cabin or van where smell has nowhere to escape.
Choose Pi-Pi over Agande
Pi-Pi Standard with a closed top or Standard Plus with a Ø70 mm ventilation port to combat summer odours. Ships within 1–2 business days, delivery across Europe in 3–5 business days. Mounts to the wall in 5–7 minutes — no plumbing required.
