The Grotto Sauna opened in 2016 in Toronto's Leslieville neighbourhood, converting an industrial heritage building into one of Canada's first urban public sauna facilities. The main sauna room — built inside a former warehouse space — can accommodate up to 15 bathers and reaches temperatures of 85–90°C. Cold plunge pools and shower facilities complete the circuit. The Grotto became an instant cultural reference point in Toronto, pioneering a model of community sauna that has since been replicated across Canadian cities. It is credited with introducing tens of thousands of city dwellers to traditional sauna practice as a regular wellness ritual rather than a hotel amenity.

Toronto's Finnish immigrant community maintained private sauna traditions throughout the 20th century, and public sauna culture was familiar in Finnish-Canadian communities in northern Ontario. The Grotto drew on this heritage while making sauna accessible to a multicultural urban population.
The Grotto has become a community anchor in Leslieville, hosting events, art exhibitions, and public education about sauna culture. Its success has inspired sauna openings in Vancouver, Calgary, Montréal, and Halifax — a national sauna renaissance in which Toronto was the catalyst.
The Grotto sources its birch firewood from sustainably managed Ontario forests. The building conversion preserved the industrial heritage structure rather than new construction. Water from cold plunges is recycled within the facility's closed-loop cooling system.
