The Boiler Room Sauna Sheffield Logo

CUMUNION is by far the largest organized pro-choice sex party in the North, and getting even bigger.  The Boiler Room Sheffield has been designed and refitted specifically for group sex, with two slings, three porn screens, and tons of open space to play in. We are pro-choice. A judgement free environment for men to meet. Members can decide for themselves what is safe sex without any judgement from others.


Set across two floors, with the usual sauna facilities on the ground floor, and the play area on the first floor, The Boiler Room Sauna has slings, cinemas, large group-play areas, darkroom, glory holes, private rooms and more. Lockers are provided free of charge, and you don’t need a pound to operate them. The venue also has a fully licensed bar. Sensible drinking only please. Hot and cold drinks are available from the lounge bar. Plenty of toilets, and a watersports area. Sexy house music is played at a decent volume throughout, creating a very horny atmosphere.

Entire cruise floor become one big darkroom with absolute minimal lighting.

“BARE” – 3rd Fridays – Naked Party
