Hi, I went to the Harrogate baths as a treat when I was at a conference recently. They are fairly small, you will have a quick guided tour and explanation on your first visit. There is a lounge area, steam room, various levels of hot room (3 degrees of heat) and a cold plunge bath, and showers. You basically go from each area to the next hottest level and use the showers and cold plunge inbetween. ( I never cold plunge!). Use the steam room whenever you fancy. They also offer treatments but you need to book these in advance, Thursdays are all female days. You need to wear your costume and bring a towel and a bottle of water.
Enjoy
Anna.
