Cost of plumbing in Nigeria 2026: New build, repairs & bathroom fitting
A complete breakdown of plumbing costs in Nigeria — per point, full house, bathroom fitting, and what honest quotes look like. Let’s start with the most important part: the numbers. Whey you will likely pay: Plumbing per point (tap, toilet, shower): ₦8,000 – ₦20,000 Full plumbing — new 3-bedroom house: ₦500,000 – ₦1,200,000 Bathroom plumbing fit-out (sanitary ware + labour): ₦300,000 – ₦1,500,000 Pipe leak repair: ₦15,000 – ₦60,000 Blocked drain clearance: ₦10,000 – ₦40,000
Plumbing is one of those crucial construction trades where the quality of work is almost completely invisible—until something goes wrong. Because you cannot see the pipes routed behind walls or buried under floor screed, it is incredibly easy for subpar materials or shortcut methods to slip through unnoticed. You typically discover issues six months down the line when a joint fails behind newly tiled walls, forcing you into expensive demolitions to fix a single leak.
This guide provides a transparent and realistic breakdown of fair plumbing costs in Nigeria for 2026, detailing what each job entails, correcting scrambled standard material profiles, and highlighting the strict rules you must enforce before any walls are closed or floors are screeded.
1. Detailed project cost breakdown
Plumbing estimates are typically calculated based on scope, accessibility, and material complexity. Below is an itemized breakdown of common residential and maintenance tasks:
| Scope / Project Type | Low (₦) | High (₦) | Scope & Notes |
|---|---|---|---|
| New plumbing point (tap, WC, shower, sink) | ₦8,000. ₦20,000 | Supply + installation per point | |
| Full plumbing — 3-bed bungalow (new build) | ₦500,000 | ₦1,200,000 | All water supply and waste pipes |
| Full plumbing — duplex (4-bed, two floors) | ₦800,000 | ₦2,000,000 | More complex routing and vertical stacks |
| Bathroom complete fit-out | ₦300,000 | ₦1,500,000 | Depends highly on sanitary ware specifications |
| Kitchen plumbing (sink + dishwasher) | ₦60,000 | ₦180,000 | Supply and waste connection lines |
| Pipe leak repair (exposed pipe) | ₦15,000 | ₦40,000 | Labour + quick fittings replacement |
| Pipe leak repair (concealed wall) | ₦40,000 | ₦120,000 | Includes careful wall opening and structural closing |
| Blocked drain clearance | ₦10,000 | ₦40,000 | Manual or mechanical rodding |
| Water pump installation | ₦60,000 | ₦200,000 | Pressure pump or borehole submersible pump supply & fit |
| Overhead tank connection | ₦30,000 | ₦80,000 | Inlet, outlet, and automatic float valve calibration |
2. Pipe material specifications guide
The material choices specified in your Bill of Quantities (BOQ) dictate the structural durability of your system. Insist on the following standards:
2.1. PPR (Polypropylene Random Copolymer): The absolute best choice for modern hot and cold water supply lines in Nigerian homes. PPR pipes are heat-fused at the joints, creating a single continuous piece of material that eliminates mechanical joint leak points. They are fully resistant to corrosion, scale buildup, UV damage, and high temperatures from solar water heaters. While more expensive upfront than uPVC, they are highly recommended for all structural lines.
2.2. uPVC (Unplasticized Polyvinyl Chloride): Best suited strictly for cold water supply and external gravity drainage. It is a standard, highly affordable option. However, its solvent-welded joints can become brittle over time, making them vulnerable to impact and UV damage. Standard uPVC should never be used for hot water supply lines.
2.3. CPVC (Chlorinated Polyvinyl Chloride): A chlorinated variant of PVC engineered to withstand higher temperatures. While better and more temperature-resistant than standard uPVC, it remains less resilient and durable than heat-fused PPR for long-term hot water distribution lines.
2.4. GI (Galvanised Iron): An obsolete standard that has been phased out of modern construction. Over 10 to 20 years, it corrodes heavily from the inside out, restricting water flow, creating recurring pinhole leaks, and contaminating potable water with rust. It should never be specified for new projects.
3. What a comprehensive full plumbing covers
When paying for a 'full plumbing house installation' for a new build, ensure your contract explicitly covers both rough-in and second-fix stages:
• Cold water supply distribution from the overhead storage tank or borehole pump directly to all building points.
• Dedicated hot water supply loops from water heaters to all master/shared bathrooms and the kitchen.
• Waste pipes route grey water from all sanitary fittings, floor drains, and sinks to the main external soil stack.
• Soil stacks extended from upper levels or roof vents down to the main external underground drainage lines.
• Underground drainage infrastructure connecting seamlessly to the soakaway system or septic tank.
• Second-fix installation of all finished sanitary ware, including WCs (toilets), washbasins, mixers, showers, and bathtubs.
THE GOLDEN RULE — PRESSURE TEST BEFORE CLOSING: Every plumbing installation must be completely pressure-tested before walls are plastered and floors are screeded. This involves filling the network with water under pressure and holding it for 24 hours to structurally verify that no joints leak. Any technician who resists pressure testing is shifting the financial risk of future structural damage onto you.
4. Frequently asked questions FAQ
How much does plumbing cost in Nigeria in 2026?
A complete plumbing installation for a new 3-bedroom house in Nigeria costs between ₦500,000 and ₦1,200,000 in 2026, covering all supply pipes, waste pipes, and sanitary ware installation. Per-point pricing for individual fittings runs ₦8,000 to ₦20,000. Leak repairs cost ₦15,000 to ₦120,000 depending on whether the pipe is accessible or concealed in a wall.
What type of pipe is best for plumbing in Nigeria?
PPR (polypropylene) pipes are the best choice for water supply plumbing in Nigerian homes. They are heat-welded at joints — eliminating the fittings that most commonly leak — and are resistant to corrosion, scale, and the high water temperatures from solar water heaters. PPR costs more than uPVC upfront but lasts significantly longer and requires far fewer repairs over the lifetime of the building.
How do I find a water leak inside a wall in Nigeria?
Signs of a concealed pipe leak include a consistently wet patch on a wall, peeling paint or plaster, mould growth, an unexplained drop in water pressure, or a constantly running water meter when all taps are closed. A plumber can isolate sections of the supply system to identify which circuit is leaking. Some technicians use thermal imaging or acoustic detection equipment for precision leak location, which is particularly useful before deciding how much wall to open.
How long does plumbing installation take for a 3-bedroom house in Nigeria?
The rough plumbing installation — laying all pipes before walls are plastered and floors are screeded — typically takes one to two weeks for a 3-bedroom bungalow. Second fix plumbing — installing all sanitary ware, taps, showers, and completing connections after tiling — takes another one to two weeks. Pressure testing is done at the end of rough plumbing, before any wall or floor is closed.
