How to Get Suction Cups to Stick on a Textured Tub or Shower

Suction cups can secure shelving, shower caddies and hooks to showers and tubs for better organization and storage of toiletries. Tubs with textured surfaces pose a problem for these handy accessories because the suction cups cannot form a strong seal and stick. However, the cups can stick with simple preparation of the textured surface.

Use sandpaper to smooth textured surfaces.

Things You'll Need

  • Bathtub cleaner

  • Hand orbital sander

  • 40-grit sandpaper

  • 150-grit sandpaper

  • Towel

  • Shampoo

Step 1

Clean the textured space where the suction cups will be applied with a bathtub cleaner.

Step 2

Sand down the area using a hand orbital sander equipped with 40-grit sandpaper. This coarse grit provides heavy sanding that will strip and flatten the textured surface.

Step 3

Sand down the same area using 150-grit sandpaper. This fine grit smooths the area, allowing for an even surface where the suction cups can stick.

Step 4

Rinse the sanded surface and wipe dry with a towel.

Step 5

Apply shampoo directly to the suction cups and press the cups firmly to the newly sanded surface. Hold the cups to the surface for about one minute for a secure set.
