The screws to hold the towel bars are too thin and are too lose due to the big hole in the glass. Are there thicker attachments to fit the glass holes? Also, the screws are tooooo long for the towel bar attachments . There are other aesthetic issues: the exposed screws that hold the door in place (attach to the tiles). Is there an attachment to hide the screws from view? Finally, the three bottom pieces that keep the glass doors in place, they are too wide and protrude. This is bad design. On the same token, the rubber pieces (three on each side) are too thin and about 1/4 inch short. Are there knobs options (as in not wanting the towel bar). Help!!
