Had an awesome session at Sauna Flo today. The setup is spot on, clean, comfortable, and seriously relaxing. Perfect way to recover after a tough workout. Feeling brand new after it!

Sauna Flo is top-notch! I jumped in after training and felt instantly relaxed. The heat was just right, and the whole experience left me feeling recharged and clear-headed. Great spot for recovery, I’ll be back for sure.

I used the sauna after a heavy weight session and it was absolutely fantastic, exactly what I needed. The heat was perfect, the environment super clean, and I came out feeling completely refreshed. Can’t recommend Sauna Flo enough if you’re looking for a proper recovery boost.
