About the Sauna Room at Frontier Residence Kinshikoen
1. A New Standard: "Residence Sauna" to Enhance the Quality of Urban Life
In recent years, with the growing interest in well-being, there has been a rapid increase in the introduction of home saunas, particularly in urban detached houses and villas. SAUNA SELECT's mission is to meet this rising demand and make "living with a sauna at home" a new standard. The installation of a sauna at "Frontier Residence Kinshikoen" embodies this philosophy, presenting a new benchmark for wellness in urban living.


2. World's No.1 Sauna Brand "HARVIA" Enables Authentic Löyly Experience
We adopted a heater from "HARVIA," a long-established Finnish sauna brand boasting the world's No.1 share. While being a home sauna, it ensures the highest quality heat source and safety, promising an authentic löyly experience. Furthermore, the "HARVIA" SOPO series is an electric sauna bath compliant product, which allowed for its installation in Sumida Ward.
3. Space Design to Deepen a Non-Ordinary Immersive Experience
The indoor bathing area was designed to be a rare, non-ordinary, and immersive relaxation space for a residence. Waterfall photos are used for the wallpaper, creating an environment where mind and body can deeply relax even in winter. Additionally, plants are arranged in the outdoor bathing area to enhance relaxation. Furthermore, an algae-motif interior is placed along the path immediately after the sauna, offering a special moment that transports you away from the urban hustle and bustle into the extraordinary.
