This private residential project is a strong example of how a swimming pool system can be designed to support multiple functions within a single space. Interpool Spa developed the pool system together with an onsen tub that was seamlessly integrated into the main pool design.
The key highlight of this project is the combination of two distinct experiences in one unified layout: a saltwater swimming pool for relaxation and everyday use, alongside a square onsen tub positioned within the pool itself to create a more unique and elevated wellness feature.
The design focused on system planning, practical use, and overall visual harmony, allowing both the swimming pool and the onsen tub to coexist beautifully within the same space while enhancing the comfort and lifestyle of the residence.
The Challenge
Combining a saltwater swimming pool and a heated onsen tub within a single integrated structure meant managing two entirely different water chemistries, temperatures, and filtration systems — while keeping the overall design looking unified and uncluttered rather than technically overloaded.
The Result
A seamlessly integrated dual-function aquatic space where the onsen tub sits within the main pool, giving the homeowner two distinct wellness experiences in one footprint — without sacrificing design harmony, outdoor space, or ease of daily use.
