St Kilda Sea Baths, Historical seaside complex in St Kilda Beach, Australia.

St Kilda Sea Baths is a pool, spa, food and entertainment complex on St Kilda Beach. The present building, completed around 2000, partly reconstructs the 1931 Spanish-Moorish baths: its twin domes were retained and placed on a reconstruction of that section, with a plainer wing to the north on the original footprint. It holds a 25 m indoor heated seawater pool, restaurants on two levels, function rooms, a courtyard between the domes and a health club.

The first bathing facility opened in 1854 as Kenny's Baths with separate fenced sections for men and women to protect privacy. Over generations, it evolved into a modern entertainment complex that adapted to changing community needs and preferences.

This place reflects how Australian beach culture shifted from strict separation of male and female bathers toward open family-friendly recreation over many decades. You can see today how locals and visitors use the space for exercise, relaxation, and social gathering by the water.

The complex stands on Crown Land managed by the Department of Environment, Land, Water and Planning with the City of Port Phillip, and is leased to an operator who sub-lets the tenancies. The 25m pool, gym and spa have been run by South Pacific Health Clubs since 2001. The pool sits between the reconstructed Moorish domes and a courtyard, with restaurants on two levels.

The 1931 Spanish-Moorish building was demolished in the 1990s; only its domes were kept and placed on a reconstruction of the twin-domed section, with a plainer block on the original footprint to the north. Artist Sidney Nolan painted bathers on a platform in the sea in the 1940s, thought to show these baths.
