I'm trying to replace my bathroom towel racks, without re-drilling holes in the wall. The previous rack's holes are wider apart than all the standard holes I'm finding in stores, so I'm not finding any brackets that fit the holes in my walls. Where can I find more specific sizes?
Purchase a towel bar to your liking that has the bar as a separate piece, longer than the spacing you need. Cut the bar to the length you need and install.
I have had to cut the bar on occasion when the space was too small for the bar on the wall, so I made it shorter.The same idea should work for you.
