Nice London hotel pool with kids

[LondonSpaPool]

I’d like to treat my DM to a nice spa day with her DDs and DGDs. Unfortunately the youngest one is only 11, so I’m looking for somewhere we can go with children. We’re not fussed about treatments, but would like a nice (preferably warm) pool we can comfortably sit around and relax.

We’re in London, so I was thinking there must be fancy hotels that have nice pools with day access that allow children in, even if it’s for limited hours. But being Londoners, we obviously never go to hotels here, so have no clue! Anyone have any recommendations?

This a special occasion, so happy to splurge (though who doesn’t love a bargain!). The girls are all very well behaved and happy to sit around and chat quietly with their DGM, so we have no worries about taking them somewhere quite grown up. DM loves a nice swanky venue!

Try Art’otel at Battersea - has a rooftop infinity pool which is heated - smaller jacuzzi type pool at the side also heated. Lovely bar area and beds around it. We had a fabulous stay there for a special birthday. Nice restaurant too. But spoiled
for choice in the area of battersea power station, lots to do for kids - opposite is a “battersea sports” area for kids . Highly recommend ! Not cheap but absolutely worth it.

The Corinthian has the best spa in London, a hotel, and pool with children’s hours . It’s amazing. Mega expensive however.
