From floating saunas to golden eggs, here are three futuristic Scandinavian spa experiences to try in Sweden and Finland, with a little help from Spa Whisperer.

Löyly Urban Sauna, Finland: powered by water and wind

Situated in the Finnish city of Helsinki, Löyly urban sauna is not only a beautiful architectural accomplishment, but a functional and social part of Finnish culture.Loyly Urban SpaBecause the majority of new living spaces are built with their own sauna, public saunas have decreased both in popularity and quantity over the years. However, Löyly, with its eye-catching design, organic eatery and idyllic location, may just change all that.Loyly Urban SpaLöyly’s big, wooden terrace partly stretches out over the sea so you can hear the sound of gently breaking waves under foot.Loyly Urban SpaTraditionally, Finnish men and women bath separately and naked. While dressing rooms remain separate, Löyly’s architects have created a unisex sauna where visitors wear bathing suits and can, therefore, mingle with friends and partners.Loyly Urban SpaMost importantly, because electricity for Löyly’s sauna and restaurant is produced with water and wind power, it is one of the greenest saunas around.Loyly Urban SpaBy Casey Gillespie, editor and founder of Spa Whisperer

Solar Egg, Sweden: a golden egg-shaped sauna

Last year, two artists, Bigert and Bergström, were commissioned to build this golden, egg-shaped sauna in Kiruna, Sweden’s northernmost town. The reason was less to attract tourists, more to draw attention to the impact of mining in the area. The entire town of Kiruna is being moved two miles east to allow for mining company LKAB to extract more iron from underneath its foundations.

The egg is made out of stainless golden mirror sheeting that reflects its snowy surroundings.

Mathias Sandberg, Riksbyggen sales and marketing director, says: “As an urban developer, Riksbyggen takes an innovative approach to sustainability and long-term relations with local residents. We want the Solar Egg to be an artistic attraction for everyone and a conversation catalyst.”

The interior has been crafted from wood, with wall panels and decking made out of pine and the bench of aspen. In the middle of the egg stands a wood-heated sauna stove made out of iron and stone. The temperature inside the egg varies between 75 degrees and 85 degrees Celsius.Bigert and Bergström said: “Saunas are places that fascinate. When Riksbyggen asked us to interpret Kiruna, we felt it was natural to explore a space that unites and encourages conversation. Saunas are sacrosanct places where you can discuss all manner of things – from the big to the small.”

Members of the public can book the sauna online at Riksbyggen will provide changing facilities, towels and other services in co-operation with Camp Ripan.Sandberg says: “The Solar Egg captures Kiruna’s fantastic spirit and its sauna traditions. It symbolises the sun as catalyst for creativity, care, hope and togetherness.”

A statement reads: “Solar Egg has been made as a social sculpture where local people and visitors to the town can meet and, for instance, discuss these challenges. In the arctic climate of Lapland the sauna occupies a key position, as a room for warmth and reflection.”
