Trosten Floating Sauna: Estudio Herreros Architectural Innovation in Oslo

The Trosten floating sauna, located next to the Munch Museum in Oslo, Norway, was finished by Estudio Herreros. The Oslo Sauna Association commissioned this installation as one of many floating saunas to spread awareness of sauna tradition. Trosten’s design blends distinct shape and vivid color in a building that is influenced by architectural follies.

Innovative Structure and Materials

The sauna’s angular timber volume was built off-site and set atop a prefabricated floating concrete platform. It is covered in aluminum with green tones made by the nearby Hydro energy company. Terrazzo tiles, wooden decking, and aluminum cladding come together to create a design that is both aesthetically pleasing and environmentally responsible.

Thoughtful Interior and Exterior Spaces

The sauna is situated on the fjord and is designed with a central stepped seating area that rises on one side, offering a view of the water while also serving as a location for activities. To improve the relationship between the sauna and its surroundings, the interior offers a wooden-clad room with stepped seating and a glazed aperture. The outdoor space allows for a smooth transition between the inside and outdoor spaces, and it features a covered seating area with access to the fjord.

Emphasis on Sustainability and Accessibility

The Trosten sauna is designed with accessibility and sustainability in mind. The design makes use of natural and recycled materials, integrates an energy-efficient system that keeps temperatures constant, and guarantees that everyone—including wheelchair users—can enter the building. The design strategy encourages inclusion while reducing its negative effects on the environment.

Enhancing Oslo’s Waterfront

This project strengthens Oslo’s commitment to sustainable and accessible public spaces while also adding a new architectural landmark to the city’s waterfront. The blending of traditional sauna culture with modern design concepts is an example of how modern community spaces may be made to be both aesthetically beautiful and practical.Trosten Floating Sauna: Estudio Herreros’ Architectural Innovation in Oslo
