Living in Wolfsburg, Germany? Then you already know or probably even tested the floating gym and spa, but for the rest of us it just looks as a dream come true.It’s a 800sqm river floating pontoon by designer Max Wehberg that includes a 40 meter long and 9 meter wide open-air swimming pool 30cm above water (includes heated water, too), a terrace, a solarium and spa amenities like massage cabins or other specific treatments that will “cause” relaxation.
