Reservoirs provide the hidden backbone of a water feature, storing water securely while keeping the focus on the fountain or sculpture above. Install one beneath your chosen piece and it will offer a stable, long-lasting base that supports a clean, continuous flow with minimal maintenance.

Thirteen reservoirs and grids from 52cm to 112cm across, £35 to £339. The reservoir is the buried half of every self-contained feature: it holds the water, hides the pump and carries the stone. Pumps are under water feature pumps, and the polished toppings under pebble pools.
Sales counts are our own deliveries, June 2025 to June 2026.

Matt's note, June 2026
Seven reservoirs went out in the twelve months to June 2026, the 52cm leading on three. The sizing rule I give every caller: the reservoir should be at least twice the diameter of the feature sitting on it, or wind blows the falling water past the catch zone and the level drops daily. Go one size up from the minimum and you top up monthly instead of weekly. Dig the hole 2cm proud, bed the rim on sand, and check level in both directions before the stone goes on.
At least twice the feature's diameter. A 40cm sphere wants an 80cm catch zone in any breeze. Bigger reservoirs also hold more water, so they need topping up far less.
From £35 to £339. The basic 67cm tub is £35, the popular 52cm grid kit £119, and the 112cm heavy-duty kit £339.
The rigid grids carry the stone features we sell for their size. Match the reservoir size band to the feature weight, and bed the rim fully so the load spreads to the ground.
Dig 2cm proud, bed the rim on sand, check level both ways. A reservoir that sits low floods with soil wash; one that leans loses water over the downhill edge.
