I'm sure the beer is better for you than the water over there is...

Any decent (4 star and up) hotel over there supplies complimentary bottled water to its guests for the duration of their stay, with the proviso to boil the tap water first if you plan on consuming it.
Actually pretty well ALL hotels do now - ever the shitters
Never stayed below 4 star in Asia. Not worth the saving or the risk,IMO.
Thanks for the info though.
