cement board in shower, corners crumbled
I am getting my bathroom remodeled, and the contractor put up the cement board around the tub and the sheetrock outside the tub area today. Tomorrow he is coming back to do spackling.
I noticed that a couple of the corners of the cement board look broken or crumbled in spots. Is this something to be concerned about?
Also, he left a small space by the side of the tub where there is no cement board. Please see the photos.
