How do i put a shower rod up against glass and make it sturdy?
They make tension shower rods that work the same as tension curtain rods. That would be my first choice. They also make brackets that are susended from the ceiling to hold the rod. Shower rods are also made in a “D” shape, with the straight side fastened to the back wall of the shower. One more thought. You could epoxy the plastic closet pole brackets to the glass and then just slip in a lightweight rod.
