As we wave farewell to one of the hottest summers on record, the spa world is already looking ahead to autumn: a new bathhouse in Glasgow, K-glass skin facials in London and the UK's largest hotel Reformer Pilates studio. Here's what's bubbling in spa and wellness this September.
GLASGOW GETS ITS FIRST UNDERGROUND BATHHOUSE
Atera, a new bathhouse and spa beneath Oswald Street in Glasgow, opens this September just a stone’s throw from Glasgow Central Station. Built by bbspa_Group, the wellness consultancy behind more than 80 projects worldwide, it brings together thermal bathing, treatments, a gym and a Mediterranean-inspired wellness café under one roof.
EVOLVE ORGANIC BEAUTY LAUNCH NEW LONGEVITY SERUM
Evolve Organic Beauty launches its EGF+ Collagen Renewal Booster on 1 September, billed as a longevity serum rather than a standard anti-ageing fix. The formula combines T-EGF, vegan spinach-derived PDRN and vegan Collagen Peptides from Arctic microalgae, plus Hyaluronic Acid and Cacay Oil. It's COSMOS Organic certified, vegan and cruelty-free.
BERLIN'S LIQUIDROM TURNS UP THE LIGHTS FOR ILLUMINA
Liquidrom, Berlin's hybrid spa-meets-nightclub, floats guests in a 36°C saltwater pool while DJs play beneath the water's surface. On 16 September, its Sound Sessions series turns into ILLUMINA, a live light experience layering lighting design over its usual mix of thermal bathing and electronic music.
A NEW SPA OPENS IN THE WILD NORTHUMBRIAN LANDSCAPE
The Retreat, Matfen Hall's new spa opens on 15 September in Northumberland, marking the final phase of the estate's £50 million, six-year renovation. Facilities include an 18-metre pool, jacuzzi, Brass Monkey ice bath, Himalayan salt sauna, traditional sauna and aromatherapy steam room. Advanced treatments stretch to whole-body cryotherapy, hyperbaric oxygen therapy and red light therapy, all set within the Grade II listed estate's grounds.
PENNYHILL PARK IS LAUNCHING THE UK'S LARGEST HOTEL REFORMER PILATES STUDIO
Pennyhill Park in Surrey opens the UK's largest hotel-based Reformer Pilates studio this autumn, answering growing demand for low-impact fitness that builds strength, mobility and long-term wellbeing. Designed by SPARCSTUDIO with Technogym equipment, the studio welcomes hotel guests, spa day visitors and members alike. Keep an eye out for launch dates and class schedules.
THE LANESBOROUGH BRINGS K-BEAUTY TO BELGRAVIA
The Lanesborough Club & Spa has launched its new K-Glass Skin Collection, and the K-Glass PDRN facial is the one everyone's talking about. Powered by South Korean salmon PDRN at 20,000ppm, double the strength typically used elsewhere, this DNA-based molecule works at a cellular level to boost collagen and elastin. Expect visible improvements to texture, tone and firmness, plus that coveted glass-skin finish.
A WILD WOMEN'S RETREAT HEADS TO THE WELSH COAST
Harmony of the Heart's Wild Women's Autumn Equinox retreat runs from 18 to 20 September in coastal mid-Wales. Expect yoga (hatha, restorative and yoga nidra) in a heated yurt, hot tub soaks, wild swimming and sauna, plus mindful walks through the Welsh landscape. Evenings bring a campfire under the stars, spontaneous dancing and seasonal meals designed to nourish body and soul, all among like-minded women.
AIRE ANCIENT BATHS LONDON: A RESET RITUAL FOR THE SEASON'S SHIFT
AIRE Ancient Baths London mastered contrast therapy before cold plunges became the wellness trend de jour. Its thermal circuit works just as well easing into autumn as escaping a heatwave. Hidden beneath the city in the former home of J.M. Barrie (author of Peter Pan), guests move through seven thermal baths, from the warm Caldarium to the brisk 10-14°C Frigidarium, easing muscle soreness and lifting energy along the way.
A SMART MIRROR WANTS TO BE YOUR HOME PERSONAL TRAINER
You’ve probably seen the Insta ads, MAGIC's AI Fitness Mirror is changing the UK home fitness game. Pairing a 32-inch display with motion-sensing cameras that correct form and count reps in real time, using what the brand calls ReflectAI technology. It builds personalised weekly workout plans from more than 100 classes and tracks body composition alongside performance - all from the comfort of your lounge.
