I can say that Humanessence Spa in QC near SM North is the cheapest massage with shower and sauna. For only 299 pesos you can have a combination massage plus the use of sauna and shower.
Again, Humanessence is the only P299 1hr. full body massage + shower and steam! you find along the Metro. The location is near Hollywood a famous massage place for gays.
What else is free? locker, towel, tea, couch area.
Settings: You can choose from open or close massage area. Open area is the usual package for the 299 only massage while close area requires you an additional fee.
Waiting: There is no chance for you to wait in here they've got plenty of therapists.
Operating hours: last call is 2 am.
May es ba here? Not sure. Maybe not
My verdict: Sulit ang pera mo dito! Sana may ganito ring set up sa Makati area
