Time Out says
The outdoor, wood-fired Hackney Wick hot tubs (formerly known as Supper Tub) are offering an apres-ski style party this winter. Guests enjoy a hot shower (compulsory – they like to keep things clean) before plunging into the steamy waters for two hours of water pistols, tunes and tub service; staff will take your drinks order and bring boozy hot chocolate or whatever else you fancy. Sessions normally cost £20 per person, but they sometimes run half price Thursdays. Book in advance.
