The hotel’s already iconic spa enters a new phase with Biome by Corinthia London, a more integrated approach that brings nature, science and performance together under one roof.
London’s wellness scene is expanding at pace. New openings promise everything from biohacking to breathwork, ice baths to infrared—an ever-growing mix of treatments, techniques and terminology. The choice can feel overwhelming, even for those who know where to look. Corinthia London cuts through the noise with Biome, a more focused, integrated approach to wellbeing. Rather than layering another standalone concept onto the mix, Biome brings everything together—structuring skincare, bodywork and performance into a single, coherent system.
The physical space itself remains familiar. Corinthia London’s spa has long been considered one of the capital’s most established wellness destinations, known for its scale and polish. Its expansive thermal floor, treatment rooms and pool remain central to the experience. Guests still move between the swimming pool, vitality pool, amphitheatre sauna, steam room, experience showers and heated marble loungers, while the treatment pods retain the same hushed, cocooning quality.
What has shifted is not so much the architecture as the intention behind it. Under Biome by Corinthia London, the spa’s existing strengths are being reinterpreted through a more structured lens: one that places treatments, recovery, nourishment and movement in conversation with each other rather than treating them as separate indulgences.
An ecosystem of care
The hotel describes Biome as “a secluded ecosystem of expert care”—a framework that marries different disciplines rather than presenting them in isolation Three specialist partners anchor the concept. Wildsmith Skin leads the nature-based approach, with treatments rooted in botanical formulations and slower, tactile techniques designed to regulate the nervous system. Augustinus Bader introduces a clinical layer, with protocols built around regenerative skincare, the brand’s TFC8 technology and long-term skin health. Completing the line-up is AMP, a performance and conditioning concept centred on movement, strength and recovery.
Together, these pillars form the foundation of what Corinthia calls “primal luxury” —an ethos that “unites instinct and intelligence, the healing rhythms of nature, and the precision of modern science”.
For general manager Charlotte Weatherall, the direction is clear. “Our spa has long been a destination in its own right, beloved by Londoners, members, and guests from around the world,” she says. “With Biome, we honour that legacy while embracing a more intentional, future-facing vision of wellbeing. It remains the sanctuary people know, now deeper, more intuitive, and more transformative than ever.”
That intent is reflected in how the space is used. Treatments, movement and recovery are no longer approached separately, but as part of a single structure designed to support longer-term results.
The full experience
Biome is best understood as an overnight experience. The format begins with a day of individual treatments and assessments, designed to combine restorative bodywork with practical wellness insight.
In our case, the experience began with a 90-minute Wildsmith Circadian Rhythm Massage, a restorative treatment tailored according to the time of day. Wildsmith’s Vitality, Purity and Stillness blends are used for morning, afternoon and evening appointments respectively; as mine took place in the afternoon, the therapist chose Purity, an oil scented with fennel, grapefruit and juniper, designed to cleanse and restore a sense of lightness.
It was followed by a one-to-one posture assessment with Nadia Alibhai, director and principal osteopath of Back 2 Well-being, which brought a more practical, corrective element to the day. The session looked beyond surface tension, identifying the underlying habits and imbalances that can shape how the body feels over time. It gave the experience a more grounded dimension, showing how Biome can address not only relaxation, but the body’s longer-term patterns and needs.
Between sessions, there was time to sink into the spa itself: the sleep pods, heated marble loungers and thermal floor, moving between sauna, cold plunge and the pools, where jets offer a kind of underwater massage. The sequence matters. Rather than moving between appointments as isolated treatments, the experience encourages a slower pace and a more holistic flow. It’s like a guided reset, with each element organically supporting the next.
That sense of continuity carried into the evening. A 45-minute meditation and sound therapy session in the spa studio was designed to support nervous system down-regulation and deep relaxation, offering a calming close to the day’s programme. Afterwards, Biome extended into the room, with a dedicated wellness menu available through in-room dining.
The menu is organised around mood and need rather than simply course. Rooted in nourishment, dishes include herb-grilled free-range chicken with root vegetables, teriyaki salmon with quinoa and vegetables, and a hormone-balancing salad of kale, beetroot, broccoli, pomegranate and seeds– all of which are generous and packed with protein, fibre, omega-3s. The dessert menu, described as “deserved pleasure, without excess”, also aims to please with options including pineapple carpaccio with lime and mint, dark chocolate mousse with caramelised hazelnuts, and matcha panna cotta with kumquats and honey. There is even wine on offer, although sparkling tea is recommended.
The following morning, the experience concludes with movement. Guests can begin with a 7am AMP fitness class in the gym, followed by a guided ecotherapy walk through the nearby St James’s Park, led by eco-psychologist Amy Steadman. The walk is restorative rather than strenuous, offering an awakening start to the day, before breakfast and departure.
Considered interventions
Across the stay, Biome is less about one standout treatment than the cumulative effect of small, considered interventions. The massage sits within a wider circadian approach, while recovery continues beyond the treatment room through movement, rest and nourishment. Its strength lies in pairing the atmosphere of a luxury spa with practitioners who can identify what the body actually needs.
Over time, new partners and wellbeing pillars will join Biome, adding further depth to the experience. “Biome is designed as a dynamic ecosystem,” spa director Aysun Mut adds. “Our vision is to create a deeply immersive, nature-rooted, and scientifically backed experience that aims to help individuals feel both grounded and renewed. Biome is about stripping away the complexities of modern life to reconnect with nature and one’s own body.”
The hotel’s spa remains one of the capital’s most acclaimed wellness destinations, but Biome by Corinthia London gives it a clearer future. Designed to evolve, it turns the space into somewhere to return to regularly, not simply a place to visit occasionally.
