Deep Blue Bath House and Day Spa

About

Deep Blue is a geothermal hot-springs resort on the Warrnambool foreshore. Open-air rock pools, sensory caves, an indoor mineral bath house and a cold plunge are all open to the public, with no hotel stay needed. The sauna is a private infrared cabin in the day spa, booked on its own or ahead of a treatment.

Good to know

• Cold plunge available on site: use it between rounds for the classic contrast cycle.
• Pool on site: works alongside the sauna for swim-and-sauna sessions or a longer cool-down between rounds.
• Hot tub on site: adds a warm-water option between the sauna and the cold plunge for a longer cycle.
• Set up outdoors: weather is part of the experience, so dress for the walk between cabin and water.
• Set in nature, away from the city, so bring a car or plan the transfer in advance.
• Right on the sea: expect saltwater dips between rounds, cold even in summer.
• Pairs the sauna with spa services like massage or a scrub, so a session can sit inside a wider visit.
• Restaurant on site, so long sessions are the design. Food is part of the visit rather than a stop on the way home.
• Bar on premises: drinks alongside (or after) the session, and the venue isn't dry like most outdoor sauna setups.
