When you need to hang a shower curtain to fit a shower installed under the eaves of a roof, sloped ceiling, or wall, you can solve the design challenge in several ingenious ways. Here are 2 options for you to attach your vinyl curtain or plastic curtain on a sloped wall.
The Suction Cup Hook Solution
Step 1 - Obtain a New Shower Curtain
A folded shower curtain has a built-in grid to help you measure where to punch new holes to follow the slope of the shower wall. Measure along the new top edge of the shower curtain with paper clips or clamps to place the new holes you will need. If a shower curtain rod has been put up, take it down.
Step 2 - Attach Suction Cup Hooks to the Sloped Section
Attach 4 or more suction cup hooks to the sloped shower wall section. Check the alignment with the paper clips or clamps on the curtain. Once you are satisfied, punch holes in the curtain and slip the cup hooks through them. Trim any excess shower curtain material. Leave the balance of the curtain straight across the top, and punch 1 new hole below the top line where the curtain meets the vertical shower wall. When you want to close the curtain, put a suction cup hook in line with this hole and slide the curtain hole over the hook.
Step 3 - Opening the Curtain to Dry
Move the suction cup hook to the ceiling of the shower to get out of the shower and affix the curtain to it so it has airflow and can drip dry in the tub or shower base.
Curved Shower Rail
Several companies now produce a curved shower rail that keeps the shower curtain away from you while you are in the shower. These work remarkably well in showers with oddly-shaped side and end walls.
Step 1 - Measure Your Shower Area's Length and Depth
Measure the shower area to find out its length from the shower head attachment to the end of the tub or stall, as well as its depth from the entrance to the far side wall.
Step 2 - Purchase the Shower Rail and Shower Hooks
Buy a curved shower rail the total length of the area you measured. Attach it to the far side wall in the corner of the sloped wall and to the shower and faucet wall just inside the tub or shower stall floor. You may need more than the standard dozen hooks and more than 1 curtain, so measure to see what you need.
Step 3 - Hang Up the Shower Curtains
Attach the hooks to the rail and hang up the shower curtains. Put 1 end hole from each curtain through 1 hook to create an overlapped seam. Extend the curtains fully open to let them dry, and wipe down the overlapped area to prevent mildew formation.
Another more expensive solution involves suspending a bent curtain rod that follows the slope, and attaching stops to the sloped part that prevent the curtain slipping downward.
