Men Factory Sauna is located on Soi 2/1 Silom Road in the heart of the gay area. If you are thinking another Babylon, think again!! This place is industrial, sleazy and not as busy, however they have not been open long.
The big advantage it has...it is open until 6am!! So if you feel like a little "relaxation" after a busy nights clubbing, this is probably the place to be!
They run special monthly nights such as Underwear and Naked Zone.
Check their website for more details (mainly in Thai)
