Top 10 Types Of Bathroom Curtains

Quick answer: Standard shower curtains and liners run 70–72 inches wide by 72 inches long — check this against your shower or tub width before buying, since an undersized curtain leaves gaps that let water splash out. For the in-shower curtain itself, PEVA or EVA (PVC-free) fabric is the more sensible choice over standard vinyl, since it avoids the plastic off-gassing smell vinyl is known for and is genuinely just as waterproof. A separate, decorative fabric curtain works well for a bathroom window (not in direct water contact) but always needs a waterproof liner behind it if it’s anywhere near shower spray, or mold becomes a real risk.

Shower Curtains vs. Window Curtains: Two Different Jobs

Worth separating clearly before choosing anything: an in-shower curtain needs to be genuinely waterproof and mold-resistant, since it’s in direct, repeated contact with water. A bathroom window curtain is a different category — decorative fabric that benefits from a humidity-tolerant material but isn’t handling direct water spray, so the priorities (light control, style, privacy) look more like a bedroom curtain than a shower curtain.

In-Shower Curtain Materials

• Fabric shower curtains (cotton, polyester, linen): A more upscale look than plastic, but they need a separate waterproof liner behind them — the decorative fabric itself isn’t meant to be the water barrier. Machine washable, which makes maintenance straightforward.
• Plastic (vinyl) shower curtains: Budget-friendly and genuinely waterproof on their own. The trade-off: standard PVC vinyl can have a noticeable plastic smell when new, and some health-conscious buyers prefer to avoid PVC specifically.
• PEVA and EVA curtains: PVC-free alternatives that are just as water-resistant as vinyl, without the associated off-gassing smell. A reasonable middle ground for anyone who wants plastic’s practicality without the vinyl-specific downsides.
• Double shower curtains: A waterproof inner liner paired with a decorative, swappable outer layer — genuinely practical, since the outer style can be changed without touching the functional inner layer, and both layers typically wash and dry quickly.

Sizing: Get This Right Before Anything Else

Standard shower curtains and liners are typically 70–72 inches wide by 72 inches long — measure your shower or tub opening against this before buying, since a curtain that’s too narrow leaves gaps at the sides that let water splash onto the floor regardless of how good the fabric or waterproofing is. Custom-made curtains are worth considering for a non-standard shower size or an unusually shaped bathroom layout, where an off-the-shelf size genuinely won’t fit properly.

Preventing Mold — The Real Risk With Bathroom Curtains

• Make sure the curtain or liner doesn’t rest directly against the tub or shower wall after use — some airflow between the curtain and any damp surface reduces trapped moisture that leads to mold.
• Fabric curtains and liners should be washed periodically, not left indefinitely — mold and mildew develop in the folds and hem where moisture lingers longest.
• A weighted or magnetic hem (common on liners) helps the curtain hang close to the tub during use, reducing splash-out, but make sure it’s not left bunched against a wet surface between uses.
• For a window curtain anywhere near shower spray or high ambient humidity, a waterproof liner behind the decorative fabric is not optional — skipping it is one of the more common causes of mold developing behind an otherwise nice-looking curtain.

Style Options Worth Knowing

• Hookless curtains: Built-in rings mean no separate shower hooks to buy or lose — a genuinely simpler installation and a cleaner look on the rod.
• Frosted or semi-transparent curtains: Let more light through than a solid curtain, which can make a small bathroom feel more open, while still offering a reasonable level of privacy.
• Waffle-weave curtains: A textured, hotel-style look in durable polyester or cotton — a step up visually from a flat vinyl curtain at a similar practical waterproof performance level (when paired with a liner).
• Bamboo or wooden curtains: More of a room-divider or privacy-screen option than a true shower curtain — works well for zoning a larger bathroom layout rather than as the water barrier itself.

Frequently Asked Questions

What size shower curtain do I need?

Standard shower curtains and liners are 70–72 inches wide by 72 inches long. Measure your specific shower or tub opening against this before buying — a curtain too narrow for the opening leaves gaps that let water splash out regardless of the fabric quality.

Is PEVA or vinyl better for a shower curtain?

Both are genuinely waterproof, but PEVA (and EVA) are PVC-free and avoid the plastic off-gassing smell standard vinyl curtains are known for when new. PEVA is a reasonable upgrade if that smell has bothered you with a vinyl curtain in the past.

Do I need a liner behind a fabric shower curtain?

Yes — decorative fabric alone (cotton, linen, polyester) isn’t a genuine water barrier. A separate waterproof liner behind it is what actually protects against water getting past the curtain and onto the floor or into the fabric itself.

How do I stop mold from developing on my bathroom curtain?

Wash fabric curtains and liners periodically, avoid leaving the curtain bunched against a wet tub or wall after use, and make sure any window curtain near shower spray has a proper waterproof liner behind it — mold most often develops in folds and hems where moisture sits the longest.
