Here is a sneak peak at one type of doorknob I used. This is the master bathroom. I picked out all the other doorknobs without any trouble but had to do some research to find these. They are dummy doorknobs, which means they screw into the door on each side of the door and do not turn at all. These are a simple ball type of doorknob and they go so much better with the overall decor style of the house.
What kind of doorknobs do you have in your house? Do you have a preference?
