Do I need both a shower curtain and a liner?

If your outer curtain is fabric: yes, you need a waterproof liner behind it. Fabric absorbs water and the wall will be damaged without a liner. If your outer curtain is vinyl or PEVA: the outer curtain itself is waterproof, so a liner is optional. Many users with vinyl curtains skip the liner entirely. Some add a cheap PEVA liner inside the vinyl to keep the decorative vinyl curtain dry and easier to clean.

What size shower curtain do I need for a walk-in shower?

For a walk-in shower without a tub, the curtain width depends on the shower opening width. Most walk-in shower curtains are 54-72 inches wide. For openings wider than 72 inches, use two panels or an extra-wide curtain. For walk-in showers with high ceilings: measure rod-to-floor and order accordingly — extra-long 72x96 or 72x84 curtains cover most walk-in shower heights.

How often should I replace my shower curtain liner?

Standard PEVA/vinyl liners last 3-6 months with regular cleaning before mildew becomes embedded in the material. Signs of end-of-life: mildew stains that do not wash out, persistent musty smell after cleaning, or material yellowing. Higher-quality EVA or fabric liners last 12-24 months. Machine-washable fabric liners last longest — wash monthly, replace when the waterproofing fails (when water soaks through rather than beading off).

Can I wash my shower curtain in the washing machine?

Polyester and microfiber fabric shower curtains are machine washable on cold or warm gentle cycle. Add white vinegar to the wash to address mildew. Tumble dry low or hang dry — high heat shrinks polyester. Vinyl and standard PEVA curtains can be machine washed on gentle/delicate, cold water only. Do not machine dry vinyl — the heat warps the material. Hang to dry. Cotton shower curtains shrink in hot water and high heat — always wash cold and hang dry.

The most important shower curtain decision is material — specifically, whether you want waterproofing built into the curtain itself (vinyl/PEVA) or a two-layer system (fabric curtain + waterproof liner). Everything else — size, color, hooks — is secondary.

Quick Decision

Daily use, simplest maintenance: vinyl or PEVA curtain, no liner needed. Best appearance, more maintenance: fabric curtain with a liner. Best long-term durability: polyester fabric curtain with a weighted PEVA liner.
