I have a bathroom bewteen two bedrooms, with the tub being on the outside wall. The exterior wall is cmu 100% filled with concrete. south facing walls, no windows. In each bedroom I notice water on the floor at base board.
the bathroom is concrete board no tile yet, outside cmu is painted. all the water pipes are on one end of tub, but notice water on each end.
It been raining alot.

Is the tub a shower combo?
Is it one pc acrylic?
Is the ground sloped away at exterior? Gutters/underground tile?

At your vent flashing - if new.

here the problem, it either migrating through the CMU or it running the seam at the concrete board and tub flange.The tub does not have a lib on it so it just a silicone seam.
Could it be migration through the concrete board.Here the question. How or if, do I check behind tub for moisture. do I pull the concrete board down, or just re silicone everything and hope it drys.when every we get heavy rain and wind it will blow against south wall. that wall has no windows, Gable end roof. its not coming in anything do with roof.so Its either migration by wind borne rain, or tubDo I start removing sheetrock?
R U saying that you are taking showers in there with just CMU bd on the walls? I would expect that to be leaking.Did you run tarpaper on the studs first?You can't expect an unfinished house to perform like a finished one, any more than you can drive your Toyota down the road with a half finished oil change.

bb.Look at the supply and drain through that access panel you should have put in.Tape up some visqueen to check the leak through the concrete board.More rain coming your way!KK
Maybe the mortar bed for the first course of block? I've seen that in basements, but if your slab is close to the gound it gets swampy enough, you could have a leak.

Is your house slab on grade or set on a cellar or crawl space?
