Peace in the bath on Passover Eve

I assume that in a bathroom under renovation it is permissible to say hello because it is now a room under renovation and not a bathroom.
Am I right?
And then after they realized at home that it was most effective to put me in the position of washing the parts of the refrigerator, the oven, and the remaining leaven dishes in the bathroom because there was no point in asking unnecessary questions about where, what, and how.
They go in there all the time and talk.
Of course, these days, with the hustle and bustle, the place is completely overcrowded, allowing for a normal shower and serving as a replacement for a sink, etc.
Entering, exiting, talking, walking around, etc.
Is it permissible to say hello there?
