The Spa Club in Ktown has free admission on your birthday! Highly recommend visiting, the facility was very clean and they provide clothing and towels. I also got a free face mask and they also offer free non alcoholic champagne! There were several saunas (salt room, red clay), along with a steam room and hot tub. I would bring a swimsuit as well. I went on a Tuesday morning and it wasn’t very busy which was nice.
