London hotels with indoor pools
London swims indoors. These are the hotel pools worth the booking — from full lap pools to candle-lit spa basements.
12 hotels in our database · Updated 19 Aug 2026
Very few London hotels have an outdoor pool, and the ones that do are seasonal. The real question in this city is which indoor pool is big enough, warm enough and quiet enough to be worth choosing a hotel for.
We separate proper lap pools from spa plunge pools in the pool facts on each hotel page, because the difference matters and hotel marketing routinely blurs it.
Everything here is scored on the same five criteria as our outdoor rankings, so a great basement pool can outrank a mediocre rooftop.

The excellent service from the spa team further elevates the pool experience.
4. The Ned
5.6City of London · Indoor heated
The Ned features an exceptional indoor pool that guests describe as feeling like "another world" with its thoughtful design. However, access to the pool may be restricted, and a fee might apply for hotel guests, which detracts from the overall service experience.

10. Park Plaza Westminster Bridge
3.1Waterloo · Indoor heated
The Park Plaza Westminster Bridge features an indoor pool, which according to the hotel description is a key amenity. However, a guest review highlights a significant drawback: the pool operates on a 30-minute reservation system that is difficult to secure and feels too short for proper enjoyment. This suggests while the pool is present, its accessibility and inherent limitations diminish its appeal as a central highlight of the stay.
11. K West Hotel & Spa
2.1Shepherd's Bush · Indoor heated
The K West Hotel & Spa features an indoor heated pool as part of its spa facilities. While some guests find the spa relaxing, the pool itself is noted as being somewhat small. Access to the spa and pool comes at an additional cost, which several guests found to be a drawback.
12. Royal Lancaster London
0.0Bayswater · No pool
There is no mention of a pool or any pool-related amenities in any of the provided reviews or the hotel description. Therefore, it is highly likely that the Royal Lancaster London does not have a swimming pool available to guests.
