The Best Luxury Hotel Spas in London

Guerlain Spa at Raffles London at The OWO

Whitehall · the grandest spa in the city

Inside the restored Old War Office, this four-floor, 27,000-square-foot spa is the most talked-about in London, with a 20-metre pool, a vitality pool and Guerlain treatment suites with private showers and soaking tubs. The definitive luxury spa experience. Treatments from about £100 (about $135), half-day experiences from about £400 (about $535).

The Spa at Four Seasons Tower Bridge

Tower Bridge · gold walls and a river-view pool

Real gold on the walls, a 46-foot lap pool, a hammam suite and sound-therapy pods, all with the flawless Four Seasons service Americans know and trust. Day passes from about £160 (about $215).

The Lanesborough Club and Spa

Hyde Park Corner · a subterranean sanctuary

An award-winning spa beneath one of London’s grandest hotels, with a hydro pool, saunas and steam rooms and a wellness-led menu. Spa days from about £335 (about $450), rising to the top-tier No. 1 Hyde Park spa day.

Bulgari Spa

Knightsbridge · sleek Italian glamour

One of the most exclusive spas in London, with a striking 25-metre pool, a spa suite and impeccable treatments in the Bulgari Hotel. Discreet, polished and very luxurious.

The Spa at Four Seasons Park Lane and Claridge’s Spa

Mayfair · a rooftop spa and an art-deco icon

Four Seasons Park Lane has a rare rooftop spa with Hyde Park views, while the subterranean spa at Claridge’s pairs art-deco glamour with signature rituals. Both are Mayfair at its most refined, with packages from about £175 (about $235).

Signature Rituals and Private Suites

What sets the luxury spas apart is the ritual. The best offer signature multi-hour journeys that combine a thermal circuit, a bespoke treatment and time to relax, often with a glass of champagne. Many also have private spa suites you can book just for a couple, with your own steam room, bath and relaxation area, ideal for a special occasion or a honeymoon. If you want the ultimate, book a private suite and a signature ritual together.

What a Luxury Spa Costs in London

Indicative prices at the time of writing; they change, and dollar figures use a rate of about $1.34 to the pound. Weekends and afternoons cost more.

What you book Typical from-price (GBP) Approx (USD)
A signature treatment £120 to £250 $160 to $335
A luxury day pass with pool and thermal suite £160 to £335 $215 to $450
A half-day or full luxury spa day £375 to £665 $500 to $890
A private spa suite (per couple) from about £400 from about $535

Tip for US visitors: a service charge is often already included, and tipping culture is far lighter than at home; around 10 percent for an exceptional treatment is welcome but never expected. Arrive by private chauffeur through our sister company Chauffeurz to start the day relaxed.

How to Book a Luxury Spa Day

  • Book well ahead. The Guerlain Spa, Four Seasons and Bulgari sell their best times and suites out days or weeks in advance.
  • Choose a weekday morning. It is quieter and often better value than a weekend afternoon.
  • Ask what is included. Confirm whether your treatment includes use of the pool and thermal suite, and for how long.
  • Arrive early. Give yourself an hour before your treatment to enjoy the facilities; that unhurried time is the essence of luxury.
  • Consider an overnight. Staying at the spa hotel turns a treatment into a full escape; compare spa hotels and book ahead.

The Bottom Line

For the grandest luxury spa day in London, book the Guerlain Spa at Raffles London, the Four Seasons at Tower Bridge or the Bulgari in Knightsbridge, ideally a signature ritual with time in the thermal suite. Reserve well ahead, choose a weekday morning, and give yourself the whole day. It is one of the finest indulgences the city offers.

Frequently Asked Questions

What is the best luxury spa in London?

The Guerlain Spa at Raffles London at The OWO is the grandest, with a 20-metre pool and four floors of facilities. The gold-walled spa at Four Seasons Tower Bridge, The Lanesborough Club and Spa and the Bulgari Spa in Knightsbridge are its closest rivals. The best for you depends on your budget and whether you want a treatment or a full thermal day.

How much does a luxury spa day in London cost?

A signature treatment starts from about 120 to 250 pounds (about 160 to 335 dollars), a luxury day pass with pool and thermal suite from about 160 to 335 pounds, and a full luxury spa day from about 375 to 665 pounds. A private spa suite for two starts from about 400 pounds.

Can you visit a luxury London hotel spa without staying overnight?

Yes. Most of London’s luxury hotel spas welcome day guests through spa days and day passes, which usually include a treatment plus use of the pool and thermal suite. Book well ahead, as day-guest places at the top spas are limited and sell out.

Which London luxury spas have a private suite for couples?

Several of the top spas offer private spa suites with your own steam room, bath and relaxation area, ideal for couples and special occasions. The Guerlain Spa at Raffles London, the Four Seasons spas and the Bulgari Spa are among those with premium private suites; ask when you book.

What is the difference between this and a normal spa day?

A luxury spa day is at a five-star hotel, with grander facilities, signature multi-hour rituals, private suites and impeccable service, at a higher price. For a wider range including more affordable day spas, see our broader guide to spas in London.

Do you tip at luxury spas in London?

Tipping is far lighter than in the United States. A service charge is often already included, and a tip of around 10 percent for an exceptional treatment is welcome but never expected. There is no need to add a large gratuity on top of an included service charge.

When is the best time to book a luxury spa in London?

A weekday morning is quietest and often the best value, and it is easier to get the treatment time and suite you want. Book days or weeks ahead for the top spas, arrive an hour early to enjoy the facilities, and allow the whole day to relax fully.
