It said Parliament Hill is 60m up there ^^. I can also tell you from personal experience it is indeed unheated!
That aside though, I didn't know the Shell one was 33, I thought it was 50.
Also the knowledge of London pools is ropey at best. The Shell building has a 33m pool, Parliament Hill lido is a massive 60m (unheated) and even St. Georges Pool by is 25m.
