I just returned on 9/1/22 from a trip on Celebrity Summit and can confirm that the pictures that twodjs posted on 9/15/22 are exactly what what exists on the ship down to the fixtures and color of the tile. I don't remember the top bench being back-lit which was nice for privacy. The sauna is small, maybe 5-6 max, but it wasn't very busy so that worked out OK. I didn't discover this free, men-only sauna in the fitness center locker room until the third day of my trip. I visited everyday after that. You can enter the locker room from the pool deck or from the hallway to the spa/fitness center. Even though the front wall is glass, the small room was always hot. Some times hotter than others.
