The room formerly known as Slow House reopened in late 2025 with a new name and a warmer heart. Under Bondi, beneath the Beachouse gym, is a warren of sandstone-toned rooms built around a single glowing domed magnesium pool held at 38 degrees, which is where the name comes from. GIANT Design gave it soft organic curves and a mirrored ceiling that reads like the ocean at sunset. Around it sit more magnesium plunges at varying temperatures, two roomy ice baths, a Finnish sauna, a steam room and four private infrared suites. Come Monday mornings there is a free sound session. Sculptural, social and a little hypnotic. Come for the circuit, stay for the quiet.
