A sanctuary that grows with you. Inspired by the need for quiet spaces, this prefab bath house features a dedicated wash zone, a soak tub, and a post-bath contemplation deck. While it serves as a standalone garden retreat, the design is inherently scalable. Its modular framework allows for easy expansion into a self-contained studio—complete with a kitchenette and bedroom—making it an ideal "plug-and-play" option for housing adult children or aging parents without the overhead of a traditional home extension.
