The previous owners had no knobs and where the notch (?) goes into the door frame is all gouged out. Where do I start?
A picture would help.
A very large drill bit and an oversized strike plate should do it.
The drill bit is to clean up the hole and the large strike plate should cover up the gouges.
If the gouges are really extensive, wood putty, sand paper & marching paint or stain will fix that.
Here are a bunch of videos on replaceing your tub surround https://www.google.com/search?client=ms-android-verizon&tbm=vid&sxsrf=ACYBGNRqpDwPEvu-jt2YP2Y8kPhzZbsYQA:1573491367628&q=replace+tub+surround&sa=X&ved=2ahUKEwjO5ZiQ0OLlAhXQc98KHdg4D9gQ8ccDKAB6BAgHEAI&biw=360&bih=668&dpr=3
Were you replying to someone else? This question was about door hardware :)
Hi Jewel: Sometimes the hole in the wood doesn't matter, as long as there is room around it to screw in the strike plate, where the tongue, the thing that sticks out, goes into. It's the strike plate that is important. You probably need those. They may or may not come with the new knobs. Good luck
