Step-by-Step Guide

Standard shower curtains are 72 inches wide by 72 inches long, correct for most standard 60-inch tub/shower combinations. The curtain should extend 12 inches wider than the opening on each side and hang 1-2 inches above the floor when the rod is at standard height.

Fabric vs Vinyl: What Actually Matters Day to Day

The material choice affects every shower, not just appearance. Fabric curtains (polyester, cotton, microfiber) do not stick to skin during a shower, look like interior decor rather than bathroom equipment, and are machine washable.

Sizing Guide: What to Measure Before You Buy

Getting size wrong means the curtain either drags on the floor (mildew risk) or leaves a gap above the tub (water on the floor). Standard tub/shower combination (60 inches wide): a 72-inch wide by 72-inch long curtain covers the standard opening with overlap on each side.

Liner Selection: Weight, Magnets, and How Long It Lasts

The liner is the functional component of a two-piece setup. The curtain decorates; the liner waterproofs.

Fabric vs Vinyl: What Actually Matters Day to Day

The material choice affects every shower, not just appearance.

Fabric curtains (polyester, cotton, microfiber) do not stick to skin during a shower, look like interior decor rather than bathroom equipment, and are machine washable.

The tradeoff: they absorb water and allow it to pass through over time.

A fabric curtain without a liner will eventually damage the wall behind it from repeated water exposure.

Fabric curtains require a separate waterproof liner.

Sizing Guide: What to Measure Before You Buy

Getting size wrong means the curtain either drags on the floor (mildew risk) or leaves a gap above the tub (water on the floor).

Standard tub/shower combination (60 inches wide): a 72-inch wide by 72-inch long curtain covers the standard opening with overlap on each side.

Rod-to-floor distance at standard mounting height is about 72 inches, the curtain should end 1-2 inches from the floor.

Walk-in shower with high ceiling: measure from rod mounting location to floor.

If more than 72 inches: order a 72x84 or 72x96 curtain.

Liner Selection: Weight, Magnets, and How Long It Lasts

The liner is the functional component of a two-piece setup.

The curtain decorates; the liner waterproofs.

Weighted hem magnets: a liner without hem weights or magnets billows into the shower during use.

The magnets attach to the inside of the tub and keep the liner bottom pressed against the tub edge, preventing water from escaping under the liner.

This is the most important practical liner feature.

Frequently asked questions

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. Cotton shower curtains shrink in hot water and high heat, always wash cold and hang dry.
