Shower rods and shower curtains prevent water from splashing onto your bathroom floor. This may seem incidental, but it goes a long way in protecting your floor from rot. To get the most protection from your shower rod, hang it in the right place. This is not a science, but there are a few things to consider before you install.
The height of the shower-rod placement is one of the most important factors to consider. This height is usually determined by the length of the shower curtain. So, measure it first and then measure up the side of the shower wall to determine where to place your rod.
Showers with Shower Pans
If your shower has a shower pan and no tub lip, the shower curtain runs the entire length from the floor to the top of the rod. Therefore, it is important to measure the length of the curtain with a tape measure and transfer this measurement onto the shower wall. Add 1 inch to account for the length of the shower rings. The shower curtain hangs down about 1 inch from the center of the rod because of the rings. Add another 1/4 inch to the overall measurement so the curtain does not drag on the floor. Follow this method and the shower curtain hangs perfectly.
Showers with Sidewalls
Showers with sidewalls have a small lip formed by the edge of the tub sidewall and your bathroom wall. The shower rod does not mount to these walls in most cases. It mounts to the bathroom wall, about 1 inch above this sidewall. The mounting brackets screw into place in the bathroom wall's drywall. If you drill into the tub sidewalls, which are made of fiberglass, you ruin the watertight nature of the tub walls. If your shower rod is spring loaded with plastic nubs on the end, mount it anywhere you like. It installs on tub sidewalls or bathroom walls.
Leveling Shower Rods
Once you find the proper height, level the shower rod. Install the first bracket by screwing it into place. Then install the rod and place a level across the length of the rod. Hold it while you level the rod. Once level, have an assistant mark where the rod intersects the other wall. Install your brackets using these marks for a level rod. If you find the rod sags, or is not level after mounting the brackets, take one bracket out, re-level the rod and install the bracket again.
