Best Indoor Pool Hotels in London
London's best indoor pool hotels cluster around Knightsbridge, the West End and the theatre district, where five five-star properties keep a heated pool running regardless of the weather outside. One Aldwych keeps its pool inside a lower-ground wellness centre near Trafalgar Square, Corinthia London pairs its pool with a spa three minutes from Embankment station, and The Peninsula London sits within a kilometre of Buckingham Palace with a pool alongside a sun terrace. Raffles London at The OWO and the Haymarket Hotel both tuck a pool into a spa a short walk from the West End's theatres, which suits an evening swim before curtain.
London runs on indoor comfort during a working week that rarely stops for weather. The city's five-star hotels answer that with spas built as private retreats rather than public leisure centres, tucked below street level or behind a discreet corridor off the lobby. A pool here reads less like a resort feature and more like an extension of the room, something guests slip into between a meeting and dinner rather than plan a whole afternoon around.

Where to stay
What five indoor pools actually offer
An indoor pool solves the one problem an outdoor deck cannot in this city: London stays grey and cool for most of the year, and a pool that depends on sunshine sits empty half the time. Every property on this list keeps the water heated and the room climate-controlled, so a swim works the same in January as it does in July, before breakfast or after a full day of meetings.
Corinthia London puts its indoor pool inside a spa and wellness floor alongside a sauna and steam room, three minutes' walk from Embankment Underground station and close enough to Trafalgar Square to combine an early swim with a walk through the West End before lunch. The hotel also lends guests complimentary bicycles, which pairs well with a pool visit for anyone building movement into a short business trip. Rooms overlook either the city or the river, and the family-friendly restaurant runs breakfast through dinner, so a full day here can start and end at the pool without leaving the building.
The Peninsula London keeps its indoor pool on a floor with a sun terrace and sauna, less than a kilometre from Buckingham Palace and a sixteen-minute walk from Harrods. That terrace matters more than it might sound: a pool with direct access to daylight and outdoor air feels different from one buried in a basement, even when the water itself stays indoors. Guests staying for the shopping around Knightsbridge or a walk through St James's Park get a pool that works as a proper break rather than an afterthought squeezed between errands.
Raffles London at The OWO built its pool into a wellness centre inside a former government building near Whitehall, four minutes from Embankment Underground and three hundred metres from Trafalgar Square. The location matters for anyone splitting a stay between sightseeing and swimming, since the National Gallery sits four hundred metres away and Big Ben is an eight-minute walk. A pool this close to the main sightseeing route means a stay does not have to choose between the two, and the wellness centre stays open into the evening for guests who would rather swim after a full day out than before it. The building's grand, formal architecture makes the low-lit pool room feel like a genuine escape rather than a hotel afterthought.
The Haymarket Hotel keeps a smaller, quieter pool next to its gym and spa, in the middle of London's theatre district and literally next door to the Theatre Royal. St James's Park is a five-minute walk and Buckingham Palace fifteen, which puts a swim within easy reach of an evening at the theatre. Guests who want to fit a pool into a day built around a show, rather than the other way round, get the most out of this one. The pool stays small enough that it rarely feels crowded even at the evening rush before curtain time, which is not something every West End hotel with a pool can claim once ticket holders start arriving for early dinners.
A traveler's takeI checked into Corinthia London on a work trip and used the indoor pool most mornings before the meetings started, since it is a three-minute walk from Embankment Underground and I could still be at my desk by nine. The water stayed warm even on a properly cold March morning, and the steam room afterwards did more for the jet lag than the coffee did.
Indoor poolHaymarket Hotel, Firmdale Hotels
Pool next door to the Theatre Royal
Why guests love itWe booked the Haymarket Hotel around theatre tickets and the pool turned out to be the way to fill the hours before curtain. A swim, then afternoon tea before 16:30, then a short walk to the Theatre Royal next door, the evening fit together without much planning. St James's Park the next morning was an easy five minutes away, and Buckingham Palace only a little further. The Bluetooth Bose unit in the room was a small touch we did not expect but used every evening after the show.
Indoor poolOne Aldwych
Indoor pool and wellness centre nine minutes from Trafalgar Square
Why guests love itWe chose One Aldwych mainly for the location and the pool turned out to be a genuine bonus rather than an afterthought. The wellness centre stayed quiet most mornings, and the walk to Trafalgar Square afterwards took less time than getting ready did. The family restaurant handled two different dietary requirements without any fuss. St Paul's Cathedral was an easy Tube ride for the afternoon, and we were back at the pool before dinner most evenings.
Indoor poolThe Peninsula London
Indoor pool with a sun terrace near Buckingham Palace
Why guests love itWe picked The Peninsula London mainly for the Buckingham Palace distance and the pool's sun terrace turned out to be the real highlight. Sitting by the water with actual daylight overhead, rather than in a basement spa, changed how often we used it. The interconnected rooms worked well for our group, and the Cantonese menu at dinner was a genuine change from usual hotel fare. Walking to St James's Park after breakfast became a daily habit by the third morning, easy enough that we never bothered with a taxi.
Indoor poolRaffles London at The OWO
Indoor pool 300 metres from Trafalgar Square
Why guests love itWe stayed at Raffles at The OWO mainly out of curiosity about the building, and the pool ended up a genuine reason to stay in most evenings. Three hundred metres to Trafalgar Square meant we could fit in a swim after a full day of walking without losing much time. Breakfast with champagne and pastries became the highlight of each morning, more than expected from a hotel breakfast. The National Gallery was close enough for a quick visit, and Big Ben an easy walk on our last afternoon.
Indoor poolCorinthia London
Indoor pool and sauna three minutes from Embankment
Why guests love itThe interconnected rooms made this an easy choice for our family, and the indoor pool became the default plan most afternoons once the kids tired of walking. Embankment station being three minutes away meant we never worried about the Tube schedule cutting into pool time. We took the complimentary bicycles out one morning along the river, a proper local thing to do rather than a typical hotel activity. Dinner covered everyone's preferences without much negotiation, and Trafalgar Square was an easy walk afterwards.
Local tips
- 1Ask about pool hours when you book, several of these spas close for a few hours midday for scheduled maintenance or private treatments.
- 2Bring a robe from home if you plan to move between the pool and sauna often, most hotels supply one but towel turnover can be slow at peak times.
- 3Book Corinthia London or Raffles at The OWO if Trafalgar Square sightseeing is the priority, both put you within minutes of it on foot.
- 4Choose The Peninsula London if you want the pool near a sun terrace rather than fully underground, it changes how the space feels in daylight hours.
- 5Reserve the Haymarket Hotel if evening theatre is part of the trip, the pool and the Theatre Royal sit next door to each other.
- 6Swim early rather than late afternoon, hotel pools here get busiest after five once guests are back from meetings or sightseeing.
