The measurer told us to ceiling, they said layer I changed that agreement, which I did not, later they said measures were only to end tile area, which again was false, I never dealt with the rudness and bullying, so after some disagreement, I screamed, I had no control and no say, they did what they wanted, and without permit, they left me and the job, told me that I was wrong. That's a hoot, they mess up measurements, then blame customer for not completing what was agreed on, and promised. Quality plumbing, which was only thin plastic cover over the water lever.
No green board was used either, but beware what is told and what is completed is totally opposite.
