Public swimming in the fjord was only for men. Swimsuits were unknown garments and men and women could not swim in the same place. The first public baths for women were built in the 1840s. At the end of the 19th century, it was discovered that light and sun had a positive effect and young women in particular began to sunbathe. It became more accepted to show off their bodies and from the 20th century, many baths were built around the Oslofjord.

During the interwar period, bathing life as we know it today gained momentum: – Sea bathing as "free bathing", i.e. where both sexes bathed together, gained momentum in the 1930s.

Hvalstrand bad was established on June 7, 1934 on a property separated from the Hval farm. The farm's owner, Wilhelm Roede, and shipowner Rudolf Olsen joined forces to establish a modern bathing facility with a diving tower, a slide, and an elegant restaurant.

Hvalstrand bad and Ingierstrand bad were the two most important, publicly accessible baths on either side of the Oslofjord from the interwar period and in the first decades of the postwar period. A steamboat was set up from the center of Oslo that ran shuttle services throughout the summer season.

Existing public baths were mostly used by wealthy people, who took a bath for the sake of cleanliness and health, while ordinary people bathed in the open air. This was a time when recreation and sports were seen as something that gave meaning to life, and Oslo's inhabitants wanted to get out of the city and into beautiful nature in search of "the good leisure life" as a result of most people starting to have more free time.

Eventually, the place became unprofitable, was bought by Asker Municipality and stood in disrepair until it was protected and restored in 1997. Now Hvalstrand Bad is operated as a restaurant during the summer months.
