A meditation room is a small, calm space set aside for meditation, prayer, mindfulness or simply decompressing. Also called wellness rooms or reflection rooms, they have moved from perk to expectation in larger offices, and in some cases they help meet religious accommodation obligations.
The practical points: locate it away from noisy zones, keep furnishing minimal and neutral, and make it bookable in short slots so one person cannot camp in it all day. Treating it as a bookable space in the room booking system also gives facilities honest data on whether one room is enough.
