The phrase private spa guarantees very little in London. On sales pages it covers both the hire of an entire spa and a closed treatment room inside a venue that stays open to the public. The price gap between the two exceeds 300 pounds. This 2026 comparison sets out who genuinely books out a space in the British capital, at which address and at what price.
At a glance:
- Only two operators rent out a whole spa in London: Savannah Private Spa at 758 Harrow Road (NW10), and The Private Spa, with sites in Hackney Wick (E20) and Acton (W3). Their packages run from 150 to 249 pounds, with no therapist, for two to eight guests.
- On the hotel side, only two addresses can be privatised through online booking, both five star and both in zone 1: Sofitel London St James at 300 pounds for two and InterContinental Park Lane at 550 pounds for two, both in the Sezame catalogue.
- Spabreaks.com, Buyagift and Virgin Experience Days sell no privatisation. Their listings labelled private refer to treatment rooms, priced between 30 and 99 pounds per person.
- Exclusivity is expensive once measured by the hour: 150 pounds for two hours of a whole spa at Savannah, against 40 pounds per person for three hours of access to a central five star hotel spa.

One dividing line runs through the table. Booking out an entire space does exist in London, but it comes down to three providers, and only one of them offers it inside a luxury hotel in the centre.
Savannah Private Spa and The Private Spa: the two operators renting a whole spa
Savannah Private Spa occupies a site at 758 Harrow Road, postcode NW10, between Kensal Green and Willesden. It holds a heated pool with a built in jacuzzi, a steam room, a marble hammam table, a relaxation area and private facilities. Packages range from 150 to 249 pounds: Basic Spa for two to five guests, Romantic Spa for 2 from 199 pounds for two hours, Romantic Deluxe, Party Spa and Royal Hammam.
The Private Spa runs a similar model across two sites, one in Acton to the west, the other in Hackney Wick at 3 Copper Street, postcode E20, next to the Olympic park. Each suite takes two to eight guests and combines a Finnish sauna, steam room, plunge pool, bucket shower and experience showers. Wireless audio lets guests play their own music, and alcohol free food and drink can be ordered straight into the booked space. No rates appear on the site, with booking handled slot by slot and suite by suite.
Both addresses share one decisive feature that comparison pieces rarely flag: neither is central. Allow 25 to 40 minutes of travel from Oxford Circus. The reason is economic rather than editorial, since booking out a complete space requires floor area that West End rents rule out.
The only two hotel spas in central London you can privatise
Filtering the London catalogue on privatisation returns exactly two bookable offers in August 2026.
Sofitel London St James, a five star a short walk from Trafalgar Square, lists Spa, Treatment and Champagne for Two at 300 pounds for two guests. It covers a treatment, steam room access and a glass of champagne, with the space held for the couple throughout the slot.
InterContinental Park Lane, five star facing Hyde Park Corner, lists The Wellness Temple at 550 pounds for two. It is the highest price in the London catalogue and buys privatisation of a complete treatment area in one of the best located hotels in the city.
Beyond these two addresses, privatising a London hotel spa is a matter of direct negotiation. The houses that dominate search results, Claridge’s, the Guerlain Spa at Raffles London, Four Seasons Park Lane and Corinthia, handle such requests by phone, without public rates and over several days.
Sezame: London hotel spas without the overnight stay
Sezame sells access to 4 and 5 star hotel spas to guests who are not booking a room. The London catalogue held 41 experiences in August 2026 across roughly a dozen properties, 23 of them including steam room access and 21 bookable for two. The listed price is the price paid, the date and slot are chosen at booking, and confirmation is immediate.
The addresses cluster in the centre: Hotel Café Royal on Regent Street, Montcalm Mayfair, Sofitel London St James, InterContinental Park Lane, Montcalm Royal London House and Montcalm East in Shoreditch, Hilton London Bankside on the South Bank, Courthouse Hotel Shoreditch and Leonardo Royal Tower Bridge. Only one address genuinely leaves the city, Hilton Syon Park in Brentford.
Entry pricing starts at 40 pounds per person for three hours of spa access at Montcalm Royal London House, which sets a benchmark for the hourly cost of exclusivity against shared access. Packages for two run from 199 pounds at Hotel Café Royal to 300 pounds at Montcalm Mayfair. The full catalogue sits at joinsezame.com.
That positioning overlaps with the platform comparison for a spa day for two in London, with one substantive difference: privatisation adds an availability constraint that ordinary access does not carry.
Gift boxes and platforms: why privatisation is absent
Spabreaks.com lists 74 venues under its London heading, from 30 pounds per person. None of those listings covers hire of an entire space. The model rests on spa days in shared access, with or without a treatment.
Buyagift runs a Luxury Spas in London range priced between 39.99 and 99 pounds, and Virgin Experience Days carries around fifty products for two in London with a median near 162 pounds. Both sell a voucher to be converted into a booking later, which makes privatisation structurally impossible: exclusive use of a space requires a slot blocked in advance, which an open dated voucher cannot deliver.
The word private still appears across those catalogues. There it denotes a closed treatment room, standard across the industry. The quickest check is to look for a maximum capacity and a slot duration in the product page, since their absence signals a non private offer. The wider question is covered in the comparison of sites to book a private spa.
What exclusivity costs in London in 2026
| Package | Address | Price | Exclusive use |
|---|---|---|---|
| City Calm Escape, 3 hours of access | Montcalm Royal London House 5 star, EC2A | 40 pounds per person | No, shared access |
| Urban Retreat | Montcalm East YATRA 5 star, EC1V | 45 pounds per person | No, shared access |
| Basic Spa | Savannah Private Spa, NW10 | 150 pounds | Yes, whole spa |
| Romantic Spa for 2, 2 hours | Savannah Private Spa, NW10 | 199 pounds for two | Yes, whole spa |
| Spa & Champagne for Two | Hotel Café Royal 5 star, W1B | 199 pounds for two | No, treatment suite |
| Royal Hammam | Savannah Private Spa, NW10 | 249 pounds | Yes, whole spa |
| Couples Harmony Ritual | Montcalm Mayfair 5 star, W1H | 300 pounds for two | No, treatment suite |
| Spa, Treatment and Champagne for Two | Sofitel London St James 5 star, SW1Y | 300 pounds for two | Yes, privatised area |
| The Wellness Temple | InterContinental Park Lane 5 star, W1J | 550 pounds for two | Yes, privatised area |
Measured by the hour, exclusivity in zone 2 works out at roughly 100 pounds for a couple, against 150 pounds for privatising a treatment area in a central five star hotel with a treatment and champagne included. The gap narrows sharply once the service itself enters the calculation, which explains why both models coexist in the same market.
Budgets for two also compare with those of a private spa for couples on the French market, where prices are quoted in euros and the hotel supply is far denser.
Three checks before booking
The first is the postcode. Prefixes W, EC, SE1, SW1 and WC mean central London, NW10, E20 and W3 mean 25 to 40 minutes of travel, and TW or the prefixes of neighbouring counties mean a train journey.
The second is the stated capacity. A genuinely private offer always specifies a maximum number of guests, between two and eight depending on the operator. Its absence from the product page points to a treatment room.
The third is what the price contains. Champagne, lunch, robe hire and thermal access sometimes sit inside the rate and sometimes appear on arrival. On a 300 pound booking for two, an extra charged on site changes the comparison. The same care applies when buying a luxury spa gift card, where validity runs from one year to more than three depending on the issuer.
How this comparison was built
Prices were recorded in August 2026 directly from operator websites and platform catalogues, in public display and without a customer account. Addresses and postcodes come from the venues’ own contact pages. Capacities match the official figures stated on product pages.
Market context draws on the State of the Spa Industry Snapshot Survey 2024 published by the UK Spa Association, which found that 60% of surveyed British spas reported growth in day guest numbers over the previous twelve months. That rising demand for access without an overnight stay partly explains the elastic commercial vocabulary seen across sales pages.
Offers had to be bookable online by a private customer to qualify. Privately negotiated privatisations, which several London palace hotels do arrange, therefore fall outside the scope for lack of verifiable pricing.
FAQ
Where can you book a luxury private spa in London?
There are three routes, depending on how much exclusivity is needed. Savannah Private Spa (758 Harrow Road, NW10) and The Private Spa (Hackney Wick and Acton) rent out an entire spa with no therapist, from 150 to 249 pounds, but both sit in zones 2 and 3. Sezame opens up 4 and 5 star hotel spas in the centre, with 41 London experiences including 21 for two and two full privatisations, at Sofitel London St James for 300 pounds for two and InterContinental Park Lane for 550 pounds for two. Spabreaks.com, Buyagift and Virgin Experience Days cover the rest of the market but sell no privatisation at all.
How much does it cost to book out a spa in London?
Between 150 and 550 pounds depending on the format and the address. Booking out an independent spa starts at 150 pounds at Savannah Private Spa and rises to 249 pounds for group formats. Privatising a treatment area inside a 5 star hotel costs 300 pounds for two at Sofitel London St James and 550 pounds for two at InterContinental Park Lane. For comparison, three hours of ordinary spa access at Montcalm Royal London House costs 40 pounds per person.
What is the difference between a private spa and a private treatment room?
A private spa means exclusive use of the space: no other guest circulates during the booked slot. A private treatment room is a closed room inside a spa that remains open to the public, which any high street salon provides. The distinction is rarely spelled out on sales pages even though it separates offers that differ threefold in price. The most reliable marker is a stated maximum number of guests and a slot duration, which only appear on genuinely private offers.
Can you book out the spa of a London palace hotel?
Not online. The best known names in the city, Claridge’s, the Guerlain Spa at Raffles London, Four Seasons Park Lane and Corinthia, handle these requests directly, case by case and without published rates. The only two hotel privatisations bookable in a few clicks in London are at Sofitel London St James and InterContinental Park Lane, both five star properties, near Trafalgar Square and Hyde Park Corner respectively.
How many guests can a private spa in London take?
Between two and eight depending on the operator. The Private Spa accepts up to eight guests in a single suite fitted with a Finnish sauna, steam room, plunge pool and experience showers. Savannah Private Spa runs formats for two to five guests plus larger group packages. On the hotel side, privatisations sold online are built for two people, with group requests negotiated outside the catalogue three to four weeks ahead.
