The Best Spas in London for Every Budget
London can be exhausting.
You can spend an entire day walking around the city, jumping on the Tube, meeting people, shopping, working and trying to fit one more thing into your schedule.
Sometimes, you don't need another restaurant or another attraction.
You just need a few hours where nobody expects anything from you.
That's where London's spa scene comes in.
And the good thing is that a spa day in London doesn't automatically mean spending hundreds of pounds. There are experiences from around £75, while the most luxurious hotel spas can take you well beyond £300.
So whether you're looking for an affordable treatment, a thermal experience, somewhere romantic, or a proper five-star spa day, here's where to start.
Prices mentioned below are current advertised prices checked in August 2026 and can change depending on the date, treatment and package. Always check the venue before booking.
How Much Does a Spa in London Cost?
There isn't one standard price for a London spa.
A basic treatment can cost considerably less than a full spa day, while luxury hotel experiences can include several treatments, food and access to thermal facilities.
As a rough guide:
ExperienceRough priceAffordable spa experienceFrom £75Mid-range spa package£100–£200Luxury spa day£150–£500+High-end special occasion£300+
For example, Spa Experience currently has packages from £75, while its larger packages range from £107 to £220.
At the luxury end, Mandarin Oriental Hyde Park currently offers a £150 Mandarin Spa Day from Monday to Thursday, while its Revitalising Spa Day is £460.
So before you book, decide whether you want a treatment or an entire day at the spa.
1. Spa Experience - For an Affordable Spa Day
If you want a proper spa experience without immediately entering five-star hotel prices, Spa Experience is one of the places worth looking at.
It has several London locations, including Ironmonger Row Baths, Kensington, Swiss Cottage, Waltham Forest, Woolwich Waves and Wimbledon.
And the current packages make the price range quite clear.
The Warmth Ritual is currently £75, including a 15-minute Hammam Scrub and two hours of thermal-spa access.
Its Everyday Escape is currently £107–£125, with a back, neck and shoulder massage, facial and two hours of thermal facilities.
For something longer, The Long Exhale costs £170–£185 and includes a 60-minute de-stress massage, 50-minute facial and two hours of thermal access.
So this is a good starting point if you want:
Massage + thermal facilities + relaxation
without spending luxury-hotel money.
Best for: Affordable spa days and first-time visitors.
Budget: From £75.
2. Banya No.1 Hoxton - For Something Completely Different
If you've never experienced a traditional banya, London gives you the opportunity to try one.
Banya No.1 in Hoxton is built around a thermal bathing experience rather than the usual hotel-spa format.
Its current Package No.1 is from £97 for a 2.5-hour experience, including access to the thermal facilities, a traditional Parenie ritual, and a private booth and table in the relaxation area.
The thermal facilities include a steam room, ice bath and bucket showers.
The Parenie ritual uses fragrant leafy bundles in a traditional thermal treatment, followed by cooling.
This isn't really the place to go if you simply want to lie quietly beside a swimming pool.
It's more active.
More unusual.
And definitely a different kind of London spa experience.
Best for: Thermal bathing, traditional banya experiences and trying something different.
Budget: From £97.
3. AIRE Ancient Baths - For an Atmospheric Experience
For something that feels completely removed from ordinary London life, look at AIRE Ancient Baths London.
It's located on Robert Street near Covent Garden, inside historic buildings in Westminster.
The experience is centred around thermal baths, with the atmosphere deliberately kept quiet and intimate.
Think:
Warm water.
Cold water.
Steam.
Low lighting.
Historic surroundings.
The official description talks about candlelight, orange-blossom aromas, warm water, steam and a quiet bathing environment.
This is one of the options I'd consider if you're going with a partner or simply want the spa itself to feel like an experience.
Rather than feeling like you've entered a hotel health club, the setting is a major part of why people choose it.
Best for: Couples, special occasions and atmospheric thermal bathing.
Budget: Check the current session/package when booking; prices vary by experience and time.
4. Guerlain Spa at Raffles London - For Serious Luxury
Now we're moving into a completely different price category.
Guerlain Spa at Raffles London at The OWO is one of London's major luxury hotel spas.
The spa occupies 27,000 square feet across four floors of The OWO. Facilities include a 20-metre indoor pool, vitality pool, sauna, steam room, experience showers and VIP treatment suites.
And it's not only for hotel guests.
The official Raffles information says the spa welcomes day visitors, alongside hotel guests, OWO residents and Pillar Wellbeing members.
This is the kind of place where you could make the spa itself the main event of your day.
You aren't simply paying for a massage.
You're paying for the surroundings, facilities, service and overall experience.
Best for: Luxury, milestone birthdays, anniversaries and special occasions.
Budget: Luxury pricing; check the current treatment or spa package before booking.
5. Mandarin Oriental Hyde Park - For Knightsbridge Luxury
If you want a luxury spa in one of London's most famous shopping neighbourhoods, The Spa at Mandarin Oriental Hyde Park is another strong option.
And there is an important distinction here.
You don't necessarily have to spend £300+ just to use the spa.
The current Mandarin Spa Day costs £150, Monday to Thursday, and includes daytime access to the heat and water facilities, pool and gym.
If you want a more comprehensive experience, the Revitalising Spa Day is £460 and includes:
A 60-minute 111SKIN Reparative Facial
A 30-minute massage
Use of the heat and water facilities
Lunch in Hyde Park Garden
That gives you a good idea of the difference between a spa-access day and a full luxury treatment experience.
Best for: High-end relaxation, couples and special occasions.
Budget: From £150 for the current weekday spa-day option.
6. The Dorchester Spa - For a Classic Mayfair Splurge
If you're looking for a spa where the name, location and occasion are all part of the experience, there's The Dorchester Spa on Park Lane.
The Dorchester currently describes its spa as offering treatments and wellness experiences in Mayfair, with opening hours of 8am–7pm.
Its current spa material shows the kind of price level you can expect.
For example, the current menu lists:
Escape in the City - £300 per person
and several larger experiences at around £330-£440 per person.
There is also a Time for Two experience listed at £930 for two people, although packages and menus can change, so this is exactly the sort of price you should confirm before booking.
The Dorchester is therefore much more suited to a major occasion than a casual Tuesday afternoon massage.
Best for: Anniversaries, milestone birthdays, luxury gifts and special occasions.
Budget: Around £300+ for many of the current spa experiences.
7. Surrenne Belgravia - For Wellness Beyond a Traditional Spa
If your idea of wellness goes beyond a massage and facial, look at Surrenne Belgravia.
Surrenne is positioned more as a premium wellness and longevity club than a conventional day spa.
Its Belgravia facilities include a 22-metre indoor pool, sauna, steam room, snow shower, gym, treatment rooms and Hammams.
Its current treatment menu also includes more modern recovery and wellness services, such as red-light therapy and a private recovery suite.
That makes it a different proposition from somewhere like AIRE.
AIRE is about the bathing experience.
Surrenne is much more about wellness as a lifestyle.
It is also a premium membership-based environment, so this isn't where I'd send someone looking for a cheap afternoon spa.
Best for: High-end wellness, fitness, recovery and longevity-focused experiences.
Budget: Premium; check current membership and treatment pricing.
8. Corinthia London - For a Full Luxury Spa Environment
Another name worth knowing is Corinthia London.
Its spa is designed more like a complete luxury wellness environment than a place you visit for a single treatment.
You'll find thermal facilities, relaxation spaces and treatment options alongside the hotel's wider luxury experience.
This is the sort of place to consider if you want to spend several hours relaxing rather than simply booking a one-hour massage.
The price depends heavily on the treatment or package you choose, so it's better to check the current offer than rely on an old advertised spa-day figure.
Best for: A full luxury spa experience.
Budget: Luxury.
What Actually Makes a London Spa “Luxury”?
It's easy to assume that a luxury spa simply means an expensive massage.
It isn't.
At London's higher-end spas, you're often paying for a combination of:
The location
The building
The design
Treatment quality
Therapist expertise
Thermal facilities
Swimming pools
Privacy
Service
Food and drinks
Time spent at the spa
Overall atmosphere
That's why comparing a £75 thermal package with a £460 luxury spa day isn't really comparing like for like.
The £75 experience might be exactly what you need.
The £460 experience is designed to be an entire occasion.
Spa Day or Just a Treatment?
This is one of the easiest ways to avoid overspending.
Just book a treatment if:
You mainly want a massage or facial.
You don't care about swimming.
You don't want to spend several hours there.
You want to keep your budget under control.
Book a spa day if:
You want to spend half a day relaxing.
You want access to thermal facilities.
You're celebrating something.
You're going with a partner or friend.
You want the spa to be the actual activity.
And sometimes a package makes more sense financially.
For example, Spa Experience's current packages combine treatments with two hours of thermal-spa access, rather than making you pay for each part separately.
What About Couples?
London has plenty of options for a spa date.
For something atmospheric:
AIRE Ancient Baths.
For a traditional thermal experience:
Banya No.1.
For luxury:
Raffles or Mandarin Oriental.
For a major celebration:
The Dorchester.
And you don't necessarily need to spend hundreds of pounds to make it special.
A £100-ish thermal experience followed by dinner can make a much more affordable date than booking an ultra-luxury couples' package.
How to Make a Spa Day Cheaper
A few simple choices can make a big difference.
Go midweek
Some spas have significantly different pricing depending on when you visit.
Banya No.1, for example, currently has off-peak pricing Monday to Friday before 5pm, with peak pricing later in the day and at weekends.
Look for packages
Compare:
Treatment only
with:
Treatment + thermal access
The second option can sometimes offer better value if you actually want to use the facilities.
Don't pay for facilities you won't use
If all you want is a massage, don't spend £200 extra for a pool and thermal circuit you'll never enter.
Consider locations outside the luxury-hotel circuit
You can have a genuinely relaxing experience without going to Mayfair or Knightsbridge.
What Should You Book for Your First London Spa Experience?
Under £100
Start with Banya No.1 or an individual treatment/thermal experience at a more affordable spa.
£100–£200
This is probably the sweet spot for many people.
Spa Experience has several current packages in this range, while Banya No.1 offers its Package No.1 from £97.
£200–£350
You're moving towards luxury treatments and premium spa experiences.
£350+
Now you're generally looking at a luxury spa day or a high-end treatment package.
Mandarin Oriental's current Revitalising Spa Day, for example, is £460.
£500+
At this point, you're really booking an occasion, not just a massage.
Don't Assume the Most Expensive Spa Is the Best
This is probably the most important thing to remember.
If you love:
Swimming → choose somewhere with a proper pool.
Sauna and steam → look for a strong thermal circuit.
Massage → focus on the treatment rather than the building.
Atmosphere → AIRE may appeal more than a conventional hotel spa.
Luxury → look towards Raffles, Mandarin Oriental or The Dorchester.
Affordable relaxation → Spa Experience or Banya No.1 may make more sense.
The “best” spa depends on what you actually want.
Final Thoughts
London's spa scene is much bigger than expensive hotel massages.
You can spend £75 on a thermal-and-treatment experience.
You can try a traditional banya for around £100.
You can disappear into atmospheric thermal baths.
Or you can spend several hundred pounds on a luxury hotel spa day where the treatment, facilities, food and surroundings all become part of the experience.
So before you book, ask yourself one question:
Do I want a treatment, or do I want an entire day of doing absolutely nothing?
If it's the first, don't overspend.
If it's the second, make the spa the destination.
And if you're celebrating something special, that's when London's luxury spas can really make sense.
Because sometimes the best way to spend a day in one of the world's busiest cities is to simply stop for a few hours.
Leave the Tube.
Leave the crowds.
Put your phone away.
And let London wait.
