Water Tank Prices in Kenya (2026) – Tanks, Towers & Installation
Current prices for Kentank, Roto, and TopTank tanks, plus what installation, towers, underground tanks, and pumps really cost.
Tank price is only part of the cost. A base, fittings, a stand or tower, a pump, and labour often add 30–100% to the tank price. Below are current 2026 market prices for tanks, followed by realistic installed totals so you can budget for the whole job. Prices change with resin and steel costs, so we confirm every figure in a written quote after a site visit.
What makes up the total cost

How to save on your water tank project
- Buy the right size once. Upgrading later means paying for a second base and connection.
- Larger tanks cost less per litre. A 10,000 L tank costs far less than two 5,000 L tanks plus two bases.
- Install before the dry season (January–February and July–September), when demand and prices peak.
- Combine the tank with rainwater harvesting to cut county water bills.
- Ask for a written, itemised quote that includes VAT, so there are no surprises.
