Wellness isn’t a weekend away anymore. In London, where the tempo seems to climb with every passing week, it’s becoming a daily survival tactic. The streets are pulsing, inboxes are swelling, and even the city’s green spaces buzz with activity. Amid all this, the real luxury is silence. Stillness. Time to switch off. Thankfully, these best London hotels with spas have quietly evolved into sanctuaries that rival even the most remote retreats.

Whether you’ve come straight from the boardroom, a long-haul flight, or you just want to hit that pause button, these hotels offer a rare moment to stop and realign, leaving you emerging feeling refreshed. Here are some of the very best hotels in London with spas right now.

1. For Stepping Back in Time: Raffles London at The OWO

London has its fair share of hotel openings, but few have landed with the gravitas of Raffles at The OWO (three Michelin Keys). The former Old War Office — where Churchill once roamed and Ian Fleming sharpened his spycraft — has been transformed into a kind of urban Versailles, with ten-foot-wide corridors and history etched into every balustrade.

The Guerlain Spa, buried four floors below ground, is the beating heart of this modern-day palace. A 20-metre pool glows under soft lighting, while hammams, steam rooms, and an expert team of therapists provide the kind of deep reset rarely found in the city.

Don’t let the military provenance fool you: this is a deeply luxurious escape, right down to the Guerlain beauty salon and wellness programmes curated by Pillar Wellbeing. There’s cryotherapy, Pilates, nutritional consultations — the works. Rooms upstairs lean toward theatrical: the Raffles Suite is a lacquered fantasy in chinoiserie and black marble, while the Granville Suite (named after Churchill’s favourite spy) softens things with lemony florals and claw-foot tubs.

Dining is equally ambitious and includes the one-star Mauro Colagreco restaurant. There are nine bars and restaurants in total, including a moody, spy-themed speakeasy tucked into the old MI5 records vault.

2. For The Unbeatable Views: Shangri-La at The Shard

Shangri-La at The Shard doesn’t whisper luxury — it sings it from 52 floors above London. The views alone are reason enough to check in. From your bed, watch the London Eye blink to life, or gaze across rooftops to the Thames, snaking silver through the city.

There’s no traditional spa here, but wellness finds its own rhythm. The Sky Pool, an infinity-edge gem on the 52nd floor, offers swims with a backdrop of the whole of London. The adjoining sauna wraps you in warmth and window views. In-room massages can be arranged, or hit the gym at 2 a.m. — it’s always open.

Downstairs (well, relatively speaking), the TĪNG Lounge serves British cuisine with Asian flair — think Cornish crab with yuzu kosho or an impeccable afternoon tea. For a nightcap, GŎNG bar is a destination in itself. Come for the Lilibeth cocktail — a fresh, floral blend of gin, elderflower, and citrus — served over a giant floating ice cube shaped like a diamond as a playful nod to the crown jewels locked away at the Tower of London, visible from here. It’s the perfect sunset spot.

Service is warm and intuitive, but never overbearing. Staff remember your name, your coffee order, the last book you read. It’s that rare kind of hospitality that makes you feel known.

Yes, it’s a skyscraper hotel, but one with soul — and that elusive urban London mix of buzz and stillness. For jet-lagged arrivals, romantic weekends, or just a break from the concrete below, Shangri-La offers a version of the city that feels elevated in every sense.

3. For Top-Scoring All-Round Comfort: Four Seasons Hotel London at Park Lane, Mayfair

At first glance, this Mayfair address reads classic Four Seasons — Art Deco polish, black marble floors, quietly confident service. But head to the 10th floor and you’ll find something a little more surprising: a jewel-box spa in the sky, with sweeping views over Hyde Park and a warmth that feels genuinely personal.

It’s small but considered. Floor-to-ceiling windows flood the space with natural light (a rarity in city spas), while signature facials by Linda Meredith and The Organic Pharmacy sit alongside cutting-edge treatments from Omorovicza and Cellcosmet. There’s a sauna with a skyline view, and if you’re lucky, an immersive sound bath happening that day — Sahana Sound’s sessions are deeply meditative, perfect for decompressing from city noise.

Everything flows naturally here, from spa to dinner. Downstairs, Pavyllon London by French three-star chef Yannick Alléno brings easygoing finesse to fine dining. Think elegant plates with just enough flair, served in a space that morphs effortlessly from quiet business lunch to date-night dinner, and why not a party to sounds spun by a live DJ at the weekends.

This isn’t the flashiest hotel in Mayfair — but that’s its magic. Everything works. Everyone remembers your name. And by the time you check out, you’ll wonder why you don’t spa in the city more often.

4. For Mighty Treatments Inspired By Bali: COMO Metropolitan London, Mayfair

Slip off Park Lane and you’ll find one of London’s most quietly effective sanctuaries. The rooms at COMO Metropolitan may feel a little pared-back compared to other five-star locales, but the real draw is downstairs at the COMO Shambhala Urban Escape — a minimalist haven built for proper restoration that’s a more modest offshoot of the group’s mothership; a wellness hotel folded into a jungly Balinese valley so incredibly beautiful that it could well be paradise itself.

At COMO Metropolitan London, there’s no glitter or gimmick, just deeply intuitive therapies grounded in Asian wellness philosophies. Treatments are tailored and precise, using COMO’s own blend of essential oils that’s instanty addictive upon the first whiff, and the kind of touch that recalibrates both body and mind. Therapists are among the city’s most experienced, and the mood is always calm, never clinical.

Guests are encouraged to roll out yoga mats in their rooms or take their practice outdoors — Hyde Park is only minutes away, and private sessions are easily arranged. There’s a considered approach to sustainability throughout: wooden key cards, low-waste menus, and gentle nudges toward mindful living rather than a preachy detox.

And while it might feel low-key, there’s still a pulse of Mayfair glamour, particularly at Nobu — the hotel’s restaurant, and still one of the sexiest tables in town. Grab a seat in the serene courtyard post-treatment for a fresh juice or sashimi platter and soak up the contrast: wellness without retreating from the city.

5. For Local-Secret Spa Vibes: Four Seasons Hotel at Tower Bridge

A short stroll from the Tower of London, a historic medieval castle close to Tower Bridge, this neoclassical gem whose ballroom was the site of the inaugural General Assembly of the United Nations in 1946, feels almost cinematic. Four Seasons at Tower Bridge is grand in scale — think domed ceilings, Corinthian columns, and hushed corridors echoing with 1920s glamour — but down in the spa, everything softens.

It’s a proper subterranean sanctuary. The lap pool is long and luxuriously underused, the hammam vast and steamy, and the eucalyptus-scented sauna just the ticket on a grey London afternoon. There’s a sense of space and quiet here that’s rare in the capital — a place where you can truly vanish for an hour (or three).

Treatments lean toward indulgent — deep-tissue massages, restorative facials, and rituals that blur the line between beauty and therapy. It’s the kind of spa where you emerge pink-cheeked and slow-blinking, wondering how long you were asleep.

Upstairs, the glamour continues. The Rotunda is a stunner for breakfast or afternoon tea under a sweeping frescoed ceiling. And for dinner, Mei Ume delivers elegant Japanese-Chinese fusion in a sultry dining room made for lingering.

6. For A Proper Work-Out: Mandarin Oriental Hyde Park, Knightsbridge

You know you’ve arrived at the Mandarin Oriental when the doormen tip their hats just so and the lobby’s soft scent signals instant exhale. But beyond the gilded doors and glossy marble, the hotel’s spa offers the kind of tailored wellness that feels part ritual, part reset.

The subterranean spa is a cocoon of tranquillity, with its amethyst steam room, vitality pool, and sleep-inducing loungers. Treatments are immersive: you’ll find acupuncture, sound healing, and reiki alongside Biologique Recherche facials and personalised yoga therapy. The in-house Sleep Concierge, hypnotherapist Malminder Gill, is a London insider secret — her sessions for jet lag and anxiety are pure magic.

Everything is exquisitely calibrated. And there’s an extensive fitness centre with its own pool, as well as personal training and bodywork available on request. For a deeper reset, bespoke day retreats combine movement, breath work, and body therapies.

The spa is a destination in itself, but its proximity to Hyde Park adds a unique layer — after a massage, wander into the green or just watch the horses trot by from the windowed relaxation lounge. You’re in the heart of Knightsbridge, but it feels miles away.

7. For A Sanctuary You Won’t Want to Leave: Hotel Café Royal, Piccadilly Circus

At street level, the boutique Café Royal, which has welcomed a roll call of A-listers like from Oscar Wilde and Winston Churchill to Princess Diana and David Bowie over the last 150 years, hums with the rhythm of central London — tourists spilling out of Piccadilly Circus, taxis honking, the neon glow of the West End. But step inside and the noise falls away. The chandelier in the lobby — a shimmering, 700-pound Murano glass cloud — sets the tone: elegant, extravagant, quietly theatrical.

The hotel’s spa by Akasha Holistic Wellbeing, is tucked away underground and feels like it belongs in another realm entirely. This isn’t just a place to squeeze in a massage between meetings. It’s a proper retreat, where holistic therapies meet serious spa credentials. There’s a sleek 18-metre back-lit pool, a Jacuzzi, sauna, hammam, and treatment rooms tucked into upper gallery of the spa.

Treatments range from Watsu (water therapy) to guided meditation, nutrition consults, and Reiki. It’s all grounded in the concept of the five elements — earth, water, fire, air, and Akasha, the spiritual source — though you don’t have to buy into the philosophy to feel the shift.

Back upstairs, the Oscar Wilde Lounge is the kind of place that reminds you of London’s layered history. Order a pot of Earl Grey or a glass of Champagne and settle in under the rococo ceiling for one of the city’s most decadent afternoon teas.
