Most public swimmingpools and sport venues in Madrid have either open showers or dividers but no doors. M a c f i t gyms also have showers with dividers but no doors, neither curtains. New private gyms tend to set up individual stalls. B o d y f a c t o r y, N i n e f i t n e s s or C R 7 have individual showers but also same sex sauna, where most guys stay naked. I used to enjoy a GymPass membership, so I cruisy-toured some.
