Water Feature Cost Calculator
Estimate the cost of a water feature. The size and the materials or finish are the main cost drivers, along with site preparation and access.
Your water feature details
Your estimate sits within the typical range.
A self-contained urn or bowl feature just needs a power point and water top-ups. A built wall or cascade needs a hidden reservoir, a correctly sized pump and waterproofing, which is where the cost and the longevity lie.
💰 Ways to save
- A DIY kit costs far less than a custom build if you are handy, but factor in your own time and tools.
- Level and clear the site yourself where you safely can, you are paying trade rates for any prep otherwise.
- Get a few quotes and ask what the base or slab adds, it is often a separate and underestimated cost.

Roughly $250 to $800 in 2026 for a small self-contained unit, and $2,500 to $8,000 for a large custom-built wall, cascade or feature.
