In the first sentence present perfect continous tense is used. It is used generally for actions that started in the past and are still going on.
But it is also used for actions that started in the past and have just finished and have a effect on the present moment.
In the above sentence the action has finished but we are taking about the results of it now - that the floor is wet.
In the second sentence past perfect tense is used. The sentences usually involves two actions/events both happening in the past ,one before the other.
Here the two events are- the bathroom floor was wet and that somebody took a shower.
The first event is put in past perfect form and the second in simple past. The first event here is that somebody took a shower and after it the floor got wet.
Past perfect form
V3 of have is had. So had had is used.
