Be careful what you ask for. I have been offered and accepted a Philippine sauna before. It is a tent they wrap around you covering all buy your head and then they blow steam up inside.
I believe that the Spa across from the Qualfon bldg. has a sauna room plus massage package. Just a shower after the sauna there
sorry I should have been more specific. The Qualfon bldg. by the PNP station downtown. There is a coffee shop- on the first floor and the spa is above it.
