Inspired by the serenity of the Mediterranean, Merse Wellness Spa, set to open in Osbourne Park in October 2025, is wellness reimagined. Luxe, indulgent and restorative, Perth, welcome to your world class wellness era.

Stepping into Merse you’ll find a bathed in soft, natural tones. Think a plethora of cream and stone, curved archways, terrazzo-inspired floors, brass accents and sculptural greenery. Both grounding and impossibly chic.

At its heart is Perth’s largest hot magnesium pool, promising a restorative dip. Surrounding this are cold plunge pools, a traditional hot rock sauna and infrared sauna, and a steam room, all designed to be used in tandem to help you sweat, soak, and restore in style. You’ll also find an ice fountain and monsoon showers for the ultimate contrast therapy moment, plus a salt room and rejuvenation lounge fitted with next-level recovery tech like compression treatments, LED light therapy and sound healing. Gentle lighting and circular pendants cast a warm glow across the magnesium pools and recovery zones, making every corner feel calm, cocooning, and utterly photogenic.

Every detail has been designed with intention to craft thoughtful flow between each wellness zone. It’s minimalist but warm, contemporary yet timeless. The result? A sanctuary that doesn’t just soothe the senses, but feels like a genuine escape from the chaos of daily life—equal parts luxe, restorative, and deeply inviting.

Already a hit over east with two thriving locations in Brisbane, Merse is bringing its holistic, design-led approach to WA. Founded by wellness duo Bianca Marshall and Julia Tilli, Merse’s philosophy is simple: wellness shouldn’t be an indulgence, it should be part of the everyday

Memberships are already selling fast, with the first two releases snapped up before doors have even opened, so if you’re chasing that magnesium float and infrared glow-up, you’ll want to lock yours in quickly.
