My bathroom floor is the master bath on the 2nd floor and the slope goes from the end of my sink toward my walk-in closet and includes the small room where the toilet is (separate small room from main bath room. The slope is enough that a marble will roll downhill. I did state in our sales contract that we wanted a 1 year builder's warranty, which the builder did initial & sign off on. However we have received no written warranty from her. I did notice that in the small room where the toilet is, there looks to be a slight horizontal crack in the drywall midway up the wall. I have called the city building inspector to come out to the house this week to see if there are any code violations. Any other suggestions?
