On Tuesday 27 October, Australian sports nutrition brand Rhise set up at 38° The Bathhouse in Bondi Beach, pouring Hydration electrolytes after the sauna and ReCharge collagen hot chocolate after the evening sessions.
Published 3 November 2026
On Tuesday 27 October, Rhise set up a sampling station at 38° The Bathhouse, the underground bathhouse beneath The Pacific on Campbell Parade, Bondi Beach. Guests walking out of the evening sessions found it by the towels: Rhise Hydration to replace what they had sweated out, and cups of ReCharge collagen hot chocolate to finish the night.
Why a sports nutrition brand came to a bathhouse
A bathhouse session at 38° runs 90 minutes across a traditional sauna, steam room, magnesium pools and a cold plunge. Private infrared sauna suites are booked separately. Most people spend a good part of that time sweating, then head back out onto Campbell Parade with a glass of water.
Rhise founder Ben Seymour thinks that last step falls short.
"We were there to sample our Hydration post sauna, to rehydrate what you sweated out, as replacing it with water alone isn't enough."
Sweat carries sodium and other electrolytes as well as water. Rhise built its Hydration formula for people who sweat heavily, which is why the brand chose a sauna lounge over a gym floor for this one.
