Carefully check whether the leakage at each plug is not leaking, and whether the sanitary fixture is installed, if it is installed, check whether the sanitary fixture is installed properly. If that's all right, then you should consider that there may be a problem with the joints when installing the water pipes!

Look at the water and electricity direction map of the house, and see that there are wood and buried water pipes in that place; Is there a return of moisture on the floor tiles? Don't understand? Didn't you say that there were damp marks on the concrete floor?
If you have tiled it, it may also be a problem with the tile.

It may be that the cement mortar for paving the floor tiles is too dry and the bond is not strong.
It's better to put green plants.
Normally, the height difference between the height of the tile and the outside after the decoration of the rough room can be done in the bathroom, and the waterproofing is the whole bathroom to do, whether it is a dry area or a wet area.
Analysis of the situation you described: 1. "Water leakage on the beam of the window" and "the location of the leakage is not in the lowest part of the bathroom" are normal conditions of water leakage, and the current house is generally cast in situ can play a role in waterproofing, but there is a gap between the part where the cast-in-place layer is combined with the beam or the part where the cast-in-place layer is combined with the sewer pipe, so leakage water often appears in these places. 2. What does it mean to "test the water but there is a large area of flowing water"? >>>More

The water seeped down from the tile joints, and after a long time, the water could not be drained out, and when it accumulated too much, it seeped out. Therefore, not only should we do a good job of waterproofing, but when we attach the floor tiles, we should mix the cement with waterproof adhesive to the floor tiles to avoid water seepage and drain it directly from the ground. >>>More
In your case, you can apply a penetrating waterproofing agent directly to the surface of the tile without compromising the waterproofing effect. >>>More
