I had a look at the website for this new sauna and it looks interesting. It is very unusual for a sauna to have 24 hr opening in BKK. The facilities look very impressive.
I think the customer counter on the website refers to the number of visitors to the website not to the actual sauna.
I have to agree with Midwestbttmboy32; I don't think many places are actually 'sticky rice', it is more a case of young attractive Thai guys not fancying older guys whatever their colour. I am sure in most BKK saunas if you are an attractive, young farang then you get lots of attention. Sadly I wasn't visiting saunas when I was that age
It is amazing just how many saunas there are in BKK, far more than in large UK or European cities.
