The plumber’s materials checklist for a house in Cameroon
A house's plumbing comes in three networks: supply (water pipe at 1 400 FCFA/m), waste (pipe at 3 200 FCFA/m) and the sanitary fixtures (WC 65 000, basin 48 000, shower 85 000, sink 55 000 FCFA), plus the septic tank and the water connection. For a 3-bed house, budget about 1 000 000 FCFA in materials. The trap: forgetting the drainage (tank, chambers, falls), which weighs heavily.
In plumbing, the classic mistake is to price the visible fixtures and forget the buried networks and the drainage. Here is the full checklist, item by item, at 2026 prices from the SangoImmo catalogue.
The checklist, network by network
- Supply (hot/cold water): pressure pipe (1 400 FCFA/m), fittings, isolation valves, manifold.
- Waste (foul + soil): PVC pipe (3 200 FCFA/m), bends, branches, traps, venting.
- Sanitary fixtures: WC (65 000), basin (48 000), shower (85 000), sink (55 000 FCFA) + taps.
- Drainage: septic tank (280 000), inspection chambers, soakaway, pipe falls.
- Water connection (CAMWATER): connection to the mains (125 000 FCFA).
The weight of each item (3-bed house)
The drainage (tank) and waste pipe weigh as much as the visible fixtures. These are the items most often missed in a rough quote.
Worked example: a 3-bedroom house (~80 m²)
| Item | Calculation | Cost |
|---|---|---|
| WC (pan + cistern) | 2 × 65 000 FCFA | 130 000 FCFA |
| Washbasins | 2 × 48 000 FCFA | 96 000 FCFA |
| Shower | 1 × 85 000 FCFA | 85 000 FCFA |
| Kitchen sink | 1 × 55 000 FCFA | 55 000 FCFA |
| Supply pipe (water) | 60 ml × 1 400 FCFA | 84 000 FCFA |
| Waste pipe | 45 ml × 3 200 FCFA | 144 000 FCFA |
| Septic tank | 1 × 280 000 FCFA | 280 000 FCFA |
| Water connection (CAMWATER) | 1 × 125 000 FCFA | 125 000 FCFA |
| Materials total | 999 000 FCFA |
That is about 1 000 000 FCFA in materials, excluding labour. The quantities (number of fixtures, metres of pipe) depend on the plan — change them and the total recomputes. Installation is added, often per fixture or as a lump sum.
The good-practice rules you never cut
- Pipe falls: allow 1 to 3 cm per metre so waste flows without blocking.
- Traps and water seals everywhere: this is what stops smells and back-flow.
- Soil-stack venting: without it, traps siphon dry.
- Tank and soakaway sized for the number of occupants; separate foul and soil where required.
SangoImmo checks these rules (SANS 10400, NF DTU, CEMAC practice) and flags gaps — see our guide to standards and the permit.
Producing a clean plumbing quote
Rather than recounting by hand, SangoImmo equips the wet rooms (WC, basin, shower, sink), totals the pipe and drainage, applies your prices and produces a readable line-by-line quote — with a Mobile Money deposit. Cross-check your unit prices against the materials prices guide, and compare with the 3-bedroom house price.

Frequently asked questions
- What materials do you need for a house's plumbing in Cameroon?
- Supply pipe (1 400 FCFA/m) and waste pipe (3 200 FCFA/m), the sanitary fixtures — WC (65 000), basin (48 000), shower (85 000), sink (55 000 FCFA) — with taps, plus a septic tank (280 000) and the water connection (125 000 FCFA).
- How much does the plumbing cost for a 3-bedroom house in Cameroon?
- The plumbing materials for a 3-bed (~80 m²) work out to about 1 000 000 FCFA at 2026 prices, excluding labour. The total depends on the number of fixtures, metres of pipe and the drainage (tank, chambers).
- What fall do you need for a waste pipe?
- Allow 1 to 3 cm per metre (1–3%). Too little and it stagnates; too much and the water races off leaving the solids — the right fall avoids blockages.
- How do I produce a plumbing quote quickly?
- With SangoImmo: the app equips the wet rooms (WC, basin, shower, sink), totals the pipe and drainage, applies your prices and produces an editable detailed quote in FCFA, with a Mobile Money deposit — free and offline.
