Deep in Ontario’s Muskoka Lakes, a former ice-storage hut has been reborn as the Muskoka Island Spa, skillfully redesigned by PARTISANS. Despite its modest 525-square-foot size, the transformation from a simple cabin into a serene spa is nothing short of extraordinary. With custom-milled cedar walls and Canadian Shield granite pathways, the interior offers a remarkable contrast to its humble exterior.
The spa invites you into a sequence of rejuvenating experiences, featuring spaces dedicated to sauna, cold plunge, steam bath and massage. It’s a tribute to the natural beauty of northern Ontario, crafted into the fabric of the building itself.

Preserving the cabin’s rustic charm
Externally, the spa retains the simple allure of its past life as an ice hut. Clad in dark green and highlighted with quirky yellow-trimmed windows, it nestles among the trees, blending subtly into the scenery. The original heavy timber door marks an entrance that feels both inviting and substantial.

Muskoka island spa: An intimate space with expansive comfort
Inside, the spa is cleverly compact, containing a sequence that includes a sauna, cold plunge, shower-steam room, and massage area. These spaces are designed to flow naturally, allowing you to transition effortlessly from heat to cold and back to relaxation.
The design faced the unique challenge of no road access, requiring materials to be precision-cut and pre-assembled before being transported to the island, ensuring each element fit perfectly on site.


Harmonizing stone and timber
The use of Canadian Shield granite is a standout feature, with the stone emerging organically from the floors to form basins, seats, and thresholds. This not only enhances the visual appeal but also roots the spa deeply in its geographic context.
The granite’s robust nature challenged designers, necessitating a mix of advanced digital milling and fine hand-finishing to marry these elements with the soft curves of cedar.


The art of cedar
The interplay between heavy granite and warm cedar creates a dynamic interior. Cedar forms benches, backrests, and curved features, its smooth grain offering a soft counterpoint to the granite. This blend makes you feel as though the space has been hewn directly from the island’s own materials.


Architectural legacy meets modern design
Despite the spa’s modern twist, the original ice hut’s character is ever-present. The gabled roofs and timber detailing remind you of its history, bridging past and present seamlessly.
By preserving these elements, the spa echoes the island’s innate rugged beauty while establishing its new identity as a sanctuary of relaxation.

The project required intricate planning to incorporate stone, timber, and other materials into a coherent design. Advanced 3D modeling helped ensure all components fit together seamlessly, adapting traditional techniques to modern craftsmanship.

The Muskoka Island Spa doesn’t just borrow from its surroundings; it is a part of them. Its intricate design references natural phenomena like slot canyons and eroded rock, integrating these inspirations throughout.

The exterior’s unassuming, deep green facade belies the refined complexity within. From the changing temperatures to the tactile granite and cedar, your experience is one of discovery, engaging all senses.
