Follow the simple instructions below to finish building a bathroom shelf with a towel bar, when you’ve already built the shelf and the rest of the frame for the towel bar. Now you must add the bar and mount the completed shelf on the wall.
Step 1 - Cut the Towel Bar
Using the measurements to fit your shelf, cut the towel bar according to the appropriate length of the whole shelf. Cut the bar so it is an inch longer than the measurement of the full frame. This will make the towel bar fix itself well in the frame when it is inserted into the hole of one depth wood piece to fit into the groove of the other.
Step 2 - Paint and Varnish the Bar
After your towel bar is cut to appropriate length, use the paint and brushes to paint the towel bar. As you are working with wood, you may need to apply more than one coat. When the paint is completely dry, apply varnish on the towel rod and let it dry. Apply more layers for a glossier finish.
Step 3 - Fix the Towel Bar into the Bathroom Shelf's Frame
After the paint and varnish on the towel bar has dried up, insert the bar into one of the holes on the side of the depth wood of the frame. Pass it through until it fits into the groove on the other depth wood piece. This should give you a perfectly horizontal fit, across the length but parallel to the shelf on top. If you feel that the groove is not a safe way to hold the towel bar in place, you can drill a complete hole on that side too and pass the bar all the way through. The extra inch you gave the bar will ensure it still stays suspended in the frame.
Step 4 - Mount the Bathroom Shelf and Towel Bar onto the Wall
This is the easiest step to perform in this whole process and the final step. After your frame and everything is ready, simply attach two L-brackets under the bathroom shelf using wood screws. They should be far apart, at the ends of the length of the shelf. After you've done that, use the help of a friend and lift the whole shelf structure and bring it to the spot on the wall where you wish to fix it, and using wood screws, attach it to the wall. Make sure it is mounted to the wall studs. As simple as that. Your bathroom shelf with towel bar is complete!
