Healthy skin & Showers

I shower at OTF immediately after my workout about 90% of the time but I have never seen anyone else use a shower at my studio. Literally not one person. Sometimes I feel bad if it's the last class of the morning or day like the staff is probably waiting for me to leave and I can't believe no one else showers. So do you use the showers? If I don't rinse off right after I break out! What are your OTF hygiene habits or favorite products to stay fresh after your fitness?
