Onsen By Housed

A new kind of wellness destination has landed in Sydney’s CBD, with Onsen by Housed transforming the former Tetsuya’s site into a design-led sanctuary for movement, recovery and wellbeing.

Inspired by traditional Japanese bathing culture, Onsen brings thermal bathing, performance training and quiet, considered spaces together under one roof. It’s less a gym or a spa, and more a modern wellness house built for the long game—balancing strength and stillness, effort and recovery.

The onsen is the heart of the club, designed as a shared experience for men and women. Members can move between the mineral onsen, traditional sauna, infrared sauna and cold plunge at their own pace, embracing the restorative benefits of heat and cold in a beautifully considered setting.

For those looking to train, the Performance Training Suite is a premium space built around strength, conditioning, mobility and longevity. Whether you’re training for performance or simply want to move well for years to come, the space is designed to support a considered approach to fitness, with personal training available for those looking for additional structure and accountability.

The Mat Pilates and Yoga studio runs boutique, instructor-led classes focused on posture, mobility, strength and body awareness, designed to complement both training and recovery.

Between sessions, the Botanical Bar & Co-Working Lounge serves specialty coffee, smoothies, elixir shots and wellness bites, alongside high-speed Wi-Fi for those wanting to work from the club.

For a more comprehensive experience, the Lounge Membership provides access to a private members’ lounge—a quiet retreat for resting between sessions or stepping away from the day—along with elevated recovery and wellness privileges including monthly massages, unlimited reformer Pilates, guest invitations and more.

Onsen’s membership offering brings together its core wellness facilities, with options spanning recovery, gym and personal training, Pilates and yoga. Founding Membership options are currently available for those looking to make the space part of their regular routine.

Located just minutes from Town Hall Station, Onsen sits in the heart of the city while feeling a world away from it.
