Blend the therapeutic benefits of a spa with the clean lines of your pool. Built‑in spas are integrated directly into your pool’s structure, creating a unified, elegant design that provides year‑round relaxation. Pools of Fun specialises in crafting custom built‑in spas that elevate both the beauty and functionality of your backyard oasis.
Unlike standalone hot tubs or attached spas that share a wall, a built‑in spa is constructed within the pool shell itself. The spa typically features raised walls, unique seating, and separate jets but uses the pool’s circulation, filtration and heating systems. Built‑in spas have spillovers or overflow edges that create a graceful water feature, visually connecting the spa to the pool while maintaining distinct water temperatures through separate control systems.
Integrated Relaxation & Efficiency
Built‑in spas are part of the pool’s structure, creating a seamless look without additional decking or separate installations.
They make the most of your backyard footprint by combining pool and spa into one integrated unit.
Built‑in spas use the pool’s pump, filter and heater with their own controls, saving space and reducing equipment duplication.
Water gently spills from the elevated spa into the pool, adding movement, sound and a luxurious feel.
Even when the pool is too cool for swimming, the built‑in spa can be heated separately for warm relaxation.
A custom, built‑in spa adds sophistication and appeal, attracting potential buyers and impressing guests.
By choosing a built‑in spa, you’ll enjoy the benefits of hydrotherapy without sacrificing design cohesion or outdoor space.
Built‑in spas are highly customizable to suit your aesthetic and comfort preferences:
From circular and square to custom free‑form designs, choose a shape that complements your pool’s style.
Select bench seating, ergonomic molded seats or lounge areas to accommodate your desired number of bathers.
Choose strategically placed jets for back, leg and foot massage, with adjustable pressure and flow.
Opt for an elevated spa with a spillway into the pool or an in‑line spa set at the same level as the pool deck for a sleek look.
Add LED lighting for ambiance and digital controls to adjust temperature and jet intensity with ease.
Enhance the spa’s edge with waterfalls, sheet flows or decorative tile mosaics.

In many cases, yes. It depends on your pool’s construction type, structural condition and available space. We’ll evaluate and provide recommendations.
We install dedicated plumbing and a control system that allows you to heat the spa while leaving the pool at a cooler temperature.
Since the spa shares the filtration system, regular maintenance is similar. However, frequent spa use may require additional water testing and balancing. We offer service packages to keep both in prime condition.
Built‑in spas typically have higher installation costs due to structural integration and finish work. However, they add a cohesive, upscale look and make efficient use of space.
For new pool construction, the spa is built as part of the project timeline. Adding to an existing pool takes several weeks, depending on complexity and permitting.
