The Basalt Slab Water Feature brings a quiet, grounding presence to any garden space. Priced at £459, this hand-finished hexagonal slab is carved from natural basalt stone.
We rate basalt highly for outdoor water features. It handles frost, rain, and UV exposure without cracking or fading. The dark stone develops a subtle patina over time that only improves its appearance.
At just 80mm tall, this feature sits low to the ground. It works well on patios, decking, or set into gravel borders. The gentle water flow over the flat slab surface creates a calming sound without being overpowering.
Setup is straightforward. The kit includes a submersible pump and concealed reservoir. Position the slab, fill the reservoir with water, and plug in the pump. No plumbing or mains water connection is needed.
The hexagonal shape gives it a natural, organic look. Basalt forms naturally in columnar hexagonal patterns, so this shape reflects the stone's geological origins. It pairs well with planted borders, pebble gardens, and Japanese-inspired layouts.
Frequently asked questions
Does this water feature need a mains water supply?
No, it is fully self-contained with a recirculating pump. Fill the hidden reservoir with tap water and top up occasionally to replace evaporation losses.
Can I leave the Basalt Slab Water Feature outside in winter?
Yes, basalt is naturally frost resistant and safe outdoors year-round. Drain the reservoir and disconnect the pump before the first frost to protect the electrics.
How heavy is this water feature?
Basalt is a dense volcanic stone, so expect a solid weight. We recommend two people for positioning. The compact 500mm x 400mm footprint keeps it manageable.
What maintenance does this water feature need?
Very little ongoing maintenance is required. Top up the water level weekly in warm weather. Clean algae with a soft brush and fresh water every few months.
