Independently ranked by our review of ratings, reviews and reputation · How we chose

By Elara Kestrel, Health and Medical Expert · ✓ Data verified July 2026 · 8 min read

A good spa day in London disappears fast once you factor in the wrong booking. The spas in London on this page have logged 3,246 Google reviews between them, and ratings run from 4.4 up to 4.9, tight enough that the real differences come down to what kind of experience each one actually offers rather than who's simply "better".

Short answer: 7 Bali Spa carries the top rating on this page at 4.9 stars across 320 reviews, an Authentic Balinese treatment house near Oxford Street. AIRE Ancient Baths London has the deepest track record by far, over 2,034 reviews at 4.6, for its Roman-style thermal bath circuit near Covent Garden. Prices vary hugely by format, from a single massage to a full thermal-bath day, so match the venue to what you actually want from the visit.

AIRE Ancient Baths London

4.62,034 Google reviews

AIRE Ancient Baths London is a Roman-style thermal bathhouse in Westminster, a few minutes from Covent Garden, set inside the former home of Peter Pan author J.M. Barrie. Guests move through a circuit of baths at different temperatures, including a floating pool, alongside massages and rituals built around the same thermal tour. The building itself, dim-lit and steeped in history, is as much the draw as the treatments. It's an experience-led visit rather than a quick facial or blow-dry stop.

What people praise

A genuinely distinctive Roman-bath circuit, not a standard spa menu
The floating pool and dim lighting create real immersion
Hot stone and other massages singled out as excellent
Quieter on weekday afternoons, according to guests who timed it that way
Historic building adds atmosphere you won't find elsewhere in London

Worth knowing

One guest flagged cleanliness lapses in the baths and changing rooms on a busy visit
Premium pricing for the full experience

Our take: It carries by far the most reviews of any spa on this page, over 2,034, which is why it ranks first despite a 4.6 that sits below several others here. Book a weekday if the crowd-free version matters to you.

7 Bali Spa

4.9320 Google reviews

7 Bali Spa sits just off Oxford Street and specializes in authentic Balinese treatments, training its own therapists through a school of massage in Bali before they work in the London location. The menu runs from Balinese stone massage to Phytomer slimming treatments, body scrubs and private hammam rituals for couples. Rooms are spacious with complimentary refreshments served after treatment. It's a focused massage-and-ritual spa rather than a pool-and-sauna day venue.

What people praise

Therapists trained in Bali, and reviewers say it shows in technique
Multiple named therapists (Febi, Phoebe, Michelle) praised for attentive, personalized massage
Tea and a small treat served after treatment as a nice touch
Clean, calm rooms with private shower access
Warm welcome from front-of-house staff described repeatedly

Our take: The highest rating on this page at 4.9, though its review count is a fraction of AIRE's, which is exactly why it lands second rather than first. Choose it if a genuinely skilled Balinese massage matters more to you than a big thermal circuit.

Thai Square Spa

4.4407 Google reviews

Thai Square Spa operates near Trafalgar Square, offering day-spa massages, facials and a sauna area alongside its central London location. Multiple reviewers describe traveling specifically for the calming, transportive feel after a long flight or a stressful week, and staff answer owner responses to nearly every review, positive or critical. The sauna and shower facilities sit alongside standard treatment rooms rather than a full thermal circuit.

What people praise

Massages consistently singled out as excellent, including scalp work
Calming atmosphere that reviewers say feels transportive from central London
Attentive, responsive staff who reply to feedback directly
Convenient for visitors staying centrally or arriving straight from the airport

Worth knowing

One detailed review described missing towels and a broken sauna door during a paid package visit
Changing-room layout and privacy between men's and women's areas drew a specific complaint

Our take: A solid 4.4 across 407 reviews. The massage quality is consistently praised, but the one detailed negative review is worth reading if facilities and privacy matter as much to you as the treatment itself.

Biome by Corinthia London

4.5307 Google reviews

Biome by Corinthia London is the spa at the Corinthia hotel on Whitehall Place, offering a thermal floor, pools, sauna and steam room alongside tailored treatments for hotel guests and non-residents booking a 60-minute treatment or longer. The space is designed around natural materials and a calmer, less clinical feel than a typical hotel spa. Access to the thermal floor itself is tied to booking a qualifying treatment or day pass rather than open to walk-ins.

What people praise

Facial and massage treatments, including a hot-stone-style full-body scrub, praised as deeply relaxing
Sauna, steam room and heated relaxation beds mentioned repeatedly as highlights
Lunch included with some packages, and rated highly by guests who tried it
Elegant, calm design with fireplaces and ample seating

Worth knowing

One guest found the whole facility uncomfortably warm outside the treatment rooms
A booking dispute over treatment options and pricing was reported by one guest

Akasha

4.5178 Google reviews

Akasha is the spa and wellness club at Hotel Café Royal on Regent Street, combining an 18-metre lap pool, marble hammam, sauna and steam room with a full gym and fitness class schedule. It was named London's Best Hotel Spa 2025 by Time Out, and treatments range from massage to facials layered on top of access to the pool and wellness facilities. It functions as much as a members' wellness club as a one-off spa visit.

What people praise

Named London's Best Hotel Spa 2025 by Time Out
Staff and management praised by name across multiple detailed reviews
Full facilities: lap pool, hammam, sauna, steam room and gym in one visit
Massage quality consistently called out as a highlight of the visit

Worth knowing

One guest felt a signature facial didn't match the price for the techniques used
A booked appointment time mismatch was reported by one guest

Watch: 5 Best Spas in London (2026)

How we rank

Every figure on this page comes from public Google data as of the date shown, not from opinion or payment. Rating is each spa’s live Google star average. Review volume measures how many customers have actually rated it, weighed against the others on this page. Confidence blends the two, so a strong rating backed by thousands of reviews counts for more than the same rating from a handful of guests. Recency tracks how lately people are still reviewing. No spa can pay to change these numbers.

How much does a spa day cost in London? (2026)

London spa pricing depends heavily on format. A single massage or facial sits at one end of the scale, while a full thermal-bath day or hotel spa package with lunch sits well above it. Central postcodes carry a premium over spas further from the West End, and weekend slots typically cost more than weekday mornings. None of the spas on this page had published rate cards we could cite directly, so treat any price you’re quoted as specific to that booking rather than a citywide figure, and confirm exactly what’s included before you pay.

Where these spas are across London

These spas cluster around central London, with AIRE Ancient Baths and Thai Square Spa near Covent Garden and Trafalgar Square, Biome by Corinthia on Whitehall Place, Akasha just off Regent Street, and 7 Bali Spa a short walk from Oxford Street. If you’re searching for a spa near me from the West End, Westminster or Fitzrovia, all of them are within easy reach on foot or a short taxi ride.

What to check before you book a spa

Is the treatment a standalone massage, or does it include pool and thermal facilities?
What’s included in the price: the treatment itself, facility access, food and drink, or extras on top?
Are weekend and evening slots priced higher than off-peak weekday times?
Do you need to book a minimum-length treatment to access the pool or thermal floor?
What’s the cancellation and rescheduling policy if your plans change?
Is there a dress code or anything specific to bring for the sauna or bath circuit?

Frequently asked questions

How did you choose these spas?

We started from every London spa with a real, active Google listing, then ranked by rating, review volume, consistency and how recently people were still reviewing. See How we rank above.

Are these rankings paid?

No. Rankings come from public Google data. A spa can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position.

Why does AIRE Ancient Baths rank first with a lower rating than 7 Bali Spa?

AIRE has by far the largest review base on this page, over 2,000, and our confidence score weighs rating by volume. A 4.6 backed by thousands of guests can outrank a higher rating built on a much smaller sample.

What’s the difference between a thermal bathhouse and a hotel spa?

A thermal bathhouse, like AIRE, centers on a circuit of baths at different temperatures. A hotel spa, like Biome by Corinthia or Akasha, pairs a pool and treatment menu with the wider hotel facilities. Choose by the experience you want, not just the rating.

Do I need to book ahead?

Yes. All the spas here run on appointments rather than walk-ins, and popular weekend slots book up fastest.

How often is this updated?

The data on this page carries a verified date of July 2026. We refresh listings periodically so ratings and review counts stay current.

The bottom line

For the deepest track record and a genuinely different bathhouse experience, AIRE Ancient Baths is the safe default. If a top-tier massage matters more than a pool circuit, 7 Bali Spa’s 4.9 rating makes the case. Whichever you pick, confirm what’s included in the price before you book.
