something different.
The challenge
Extending the structure without rebuilding the existing pool shell.

Shell testing and CAD-planned structural extensions, then a cast perimeter ledge, full-width corner step, earth-bonded stainless fittings and lighting.
What changed. What we kept.

The people behind the pools
A pool is a big decision.
You should know who’s building it.
Mermaid has been family-run since 1981. Today Steven and James lead the business, carrying forward the experience built across three generations. The value of that experience is not simply the number of years. It is knowing who is responsible for your project.
