communal showers in London

the leisure centre (free) right next to the imperial war museum is open showers, no-one ever uses them, would love to be eyed up...

BetterGym also have mostly open showers, the one in clapham is great ;)
What's it called Dave? I'll come eye you up !
 
To name a few off the top of my head

Marshall St Leisure Centre (Soho)
Kentish Town Leisure Centre
Archway Leisure Centre
Sobell Leisure Centre (Holloway)
Fitspace Islington
Urban Kings (Kings Cross)
Bloomsbury Fitness
Livingwell at Hilton Metropole (Paddington)
 
I'd like people to be coming to London for its vibrant arts and theatre scene, the wonderful monuments, cathedrals and palaces, the mother of parliaments, the history, the parks, the world class shopping and restaurants...

Not just the open showers. :(
