Depending on your personal specification, design astes, and material choices; a bespoke sauna installation in a domestic residence typically ranges from around £15,000-£60,000. Saunas that are much larger, more unusually designed, in spaces with difficult access, or large commercial grade saunas can cost more to produce.
