Custom
In-Ground Spas
Elevate your recovery with a permanent, hydrotherapeutic retreat. Our custom concrete spas are designed to be a seamless extension of your home’s architecture. Whether integrated into a pool design or standing as a singular stone-clad focal point, we deliver a high-performance sanctuary engineered for year-round heat and relaxation.
Architectural Integration
We specialize in "flush-mount" designs where the water's edge sits level with your stone patio. This creates a clean, zero-entry aesthetic that eliminates the bulky footprint of traditional above-ground units.

Bespoke Hydrotherapy
Every jet is placed with intention. We custom-contour the concrete seating to your specifications, ensuring ergonomic comfort and targeted relief that "one-size-fits-all" shells cannot provide.

The Technical Edge
High-Flow Jet Systems
Commercial-grade pumps and piping for powerful, therapeutic water pressure.
All-Season Performance
Advanced insulation and high-efficiency heaters designed for cold-climate operation.
Automated Chemistry
Integrated salt-water or ozone systems for crystal-clear water with minimal maintenance.
Permanent. Powerful. Precise.
An Arc Masonry spa is a structural addition to your property. By using monolithic concrete and premium stone finishes, we ensure your spa doesn't just function—it endures. This is the difference between a temporary appliance and a permanent architectural asset.
