Tips for Selecting the Right Shower Curtain

Selection

  • • Fabric: Choose waterproof or water-resistant fabrics like polyester or vinyl.
  • • Liners: Use liners for extra splash protection, especially with fabric curtains.
  • • Extension: For bathtubs, extend curtain 12–18 inches beyond each side for coverage.
  • • Weighted Hems: Use weighted hems to prevent billowing during showers.

Maintenance

  • • Washing: Wash fabric curtains monthly in cold water to keep them fresh.
  • • Liners: Use mildew-resistant liners and replace them every 6–12 months.
  • • Drying: Dry completely after use by extending the curtain fully.

Shower Curtain Size FAQs

What is the standard shower curtain size?
The standard shower curtain size is 72 inches by 72 inches (183 x 183 cm). This generic size fits most standard 60-inch bathtubs with enough width for pleats and height for standard rods.
How do I measure for a custom shower curtain?
Measure the width of the shower area and multiply by your desired fullness factor (1.5x is standard). For height, measure from the rod location to the floor and subtract 1-2 inches for clearance.
What fullness factor should I choose?
A fullness factor of 1.5 is standard, meaning the curtain is 1.5 times the width of the shower. 1.2 is minimal, while 2.0 provides a luxurious, ruffled look often seen in hotels.
How much clearance should a shower curtain have?
Ideally, leave 1 to 2 inches (2.5 to 5 cm) of clearance between the bottom of the curtain and the floor. This prevents the curtain from getting dirty, dragging, or trapping moisture that causes mold.
Can I use an extra-long curtain for a standard tub?
Yes! Installing your rod higher—closer to the ceiling—and using an extra-long curtain (84 inches or 96 inches) can make your bathroom ceiling feel higher and give a more upscale appearance.
