When we think of a sauna, the first image that probably comes to mind is a rectangular, wooden room with high and low bench seating. However, Canadian architecture firm Partisans has created something entirely different than the dark and boxy norm.

On a private island north of Toronto, the firm created a sauna that mimics the look of a grotto. This sea-cave-inspired design called for wood paneling with fluid curves to line the inside, and a bay window that looks out to the blue lake. The fluidity of the inside is contrasted on the outside, where rough, worn planks create a rigid silhouette.

The sauna is perched on a steep, rocky shoreline, so it’s no wonder it was prefabricated off-site and brought to its current location by boat. What do you think of this grotto-inspired sauna?
