# Pi-Pi — Waterless Urinals & Plumbing-Free Wall Sinks for Garden, Off-Grid & Workshop > Pi-Pi makes two things: **waterless urinals** and **plumbing-free wall-mounted sinks** — both for places with no running water and no sewer connection: garden sheds, allotments, dachas, garages, workshops, off-grid cabins, and campervans. Everything is rotomolded from LLDPE in Estonia (EU), mounts on a wall without a plumber, and stays crack-free down to −40 °C. This is NOT commercial bathroom sanitaryware — it is not for tiled bathrooms with running water. ## What Pi-Pi is (and is not) - **A waterless urinal** — a wall-mounted plastic urinal with no water, no flush, and no plumbing. Liquid drains by gravity through a hose into a canister (or an existing drain). It is designed to sit **alongside** a dry/separating/composting toilet, not to replace one: sending urine to its own container makes a composting toilet's canister fill 2–3× slower. - **A plumbing-free sink** — a wall-mounted plastic wash bowl with no water supply and no drain. You pour or feed water in; it drains by gravity into a bucket or canister below. It is a **passive drain-to-bucket bowl**, NOT a self-contained handwashing station with a built-in water tank and pump, NOT a kitchen sink, and NOT a ceramic bathroom washbasin. - **Pi-Pi does not sell:** complete toilets, tank-and-pump handwashing stations, ceramic/stainless sanitaryware, cartridge-based commercial waterless urinals, medical urine bottles, or sanitation-rental services. ## Products Two co-equal product lines, 5 active models (source of truth: `src/data/products.json` — do not quote prices from this file, they change; see the live product pages). **Waterless urinals** (`/products/urinals`): - **Standard** (`/products/urinals/standard`) — wall-mounted waterless urinal, stepped outlet Ø24/32/40 mm. - **Standard Plus** (`/products/urinals/standard-plus`) — as Standard, plus a Ø70 mm top inlet. - **Standard Corner** (`/products/urinals/standard-corner`) — corner-mounted variant with the Ø70 mm top inlet. **Plumbing-free sinks** (`/products/sinks`): - **Sink** (`/products/sinks/sink`) — straight wall-mounted plumbing-free wash bowl, stepped outlet Ø24/32/40 mm. - **Sink Corner** (`/products/sinks/sink-corner`) — corner variant of the same bowl. Shared characteristics: seamless rotomolded LLDPE, ~4–5 mm wall, ~1.4–1.5 kg, wall-mounted, no water and no sewer connection, stepped outlet Ø24/32/40 mm to fit a hose or a composting-toilet drain, service temperature −40 °C … +60 °C, made in Estonia (EU). ## Who it's for **Primary — private buyers (B2C):** owners of garden sheds, allotments (DE Schrebergarten/Kleingarten, PL działka, DK kolonihave, SE kolonilott, FI mökki), dachas, garages and workshops, off-grid homes, cabins and campervans — anyone who needs a urinal or a hand-wash point where there is no plumbing. The urinal is most often bought as a companion to a dry/composting/separating toilet (Trelino, BOXIO, Kildwick, Separett, Trobolo, OGO); the sink is bought on its own to wash hands where there is no tap. **Secondary — B2B, via non-cold channels only:** garden/DIY/outdoor retailers and distributors, dry-toilet resellers, cabin OEMs, and rental fleets reach Pi-Pi through wholesale/distributor relationships, public tenders, and marketplace B2B — plus the inbound `/b2b/` landing page. Pi-Pi does not run cold outbound sales. ## Material & manufacturing - **LLDPE** (linear low-density polyethylene): stays flexible in the cold and absorbs impacts instead of cracking. Frost-resistant down to −40 °C, service range −40 °C … +60 °C. Resin: density 0.935–0.940 g/cm³, MFI 4–8 g/10 min (190 °C / 2.16 kg). - **Rotomolding** (rotational moulding), not injection moulding: gives a seamless, single-piece wall with no seams or joints where residue or odour could collect. - Manufactured on Pi-Pi's own rotomolding line in Estonia (EU); the workshop has run rotomolded products since 2011. ## How it works (odour & drainage) - **No smell by design:** ammonia odour appears when urine mixes with the solid fraction. Because a Pi-Pi urinal keeps liquid separate and the surface is seamless, there is nothing for residue to cling to. Liquid runs off by gravity into a canister and can be diluted ~1:10 for use as fertiliser. - **No water, no drain, no bills:** nothing to freeze, nothing to plumb, no flush and no running costs. The stepped Ø24/32/40 mm outlet fits a standard hose or a composting-toilet drain. ## Site structure - `/` — homepage (both product lines, how to order) - `/products` — catalog (urinals + sinks) - `/products/urinals`, `/products/urinals/[model]` — waterless urinals - `/products/sinks`, `/products/sinks/[model]` — plumbing-free sinks - `/lldpe` — why the material survives frost (LLDPE vs PP) - `/compare` — honest comparisons with other waterless urinals - `/use-cases` — garden, off-grid, workshop and companion-to-dry-toilet scenarios - `/faq` — questions on product, install, odour, and B2B - `/b2b` — wholesale, distribution, tenders, public sector (inbound) - `/contacts` — written contact form for product, order, shipping, or a sample - `/checkout` — online purchase for individual orders ## Buying & contact - **Individual buyers** buy online: browse the catalog, add to cart, check out.
