I am about to redo my laundry room. I am going to take out the old subfloor, replace it and lay tiles down. I noticed that laying tiles + mortar will add height to the floor. This isnt a problem for the door because it swings out...but it will create a small step right when you are entering the laundry room. What do people do about this? I dont even know how to search google for this information because I have no idea what key terms to put out
