According to sources, Valhallabadet received a bronze medal in architecture at the 1948 London Olympics for the proposal by architect Nils Olsson. This bronze medal was Sweden's only one at those Olympics. Nils Olsson died shortly after, in 1951, though the exact cause of his death is not known.
Architect Gustaf Samuelsson completed the internationally acclaimed bath in 1956, but the specific nature of this acclaim has not been detailed. The bath includes a 700-square-meter mosaic artwork on the wall by the pools, created by artist Nils Wedel. The motifs of the mosaic remind of water and summer and shimmer in light pastel colors.
The shimmering effect of the mosaic was even more visible before the light inlet in the ceiling was covered, though it is unclear why this covering occurred. There is no information on current plans to restore or uncover the light inlet to enhance the mosaic's effect. The bath's usage or condition since its completion in 1956 has not been reported.
