Shower curtain vs shower door

What each one actually is

A curtain is usually two layers on the rod you already have: a waterproof liner hanging inside the tub, and a fabric curtain outside it. Both come down in seconds and both can be replaced for the price of a textile.

A glass door is a fixture. Wall jambs are fixed to the walls, a track sits on the tub or shower ledge, and heavy tempered panels slide on rollers. The Levity bypass here weighs 81.72 lb; the Cursiva, 142 lb.

Keeping water in

Both work when they are fitted properly, and both fail when they are not. A curtain setup relies on the liner hanging inside the tub and being drawn fully closed. A door relies on its jambs and track sitting on flat surfaces: Kohler’s Levity sheet lists minimum flat widths of 2-1/2 in. on the ledge and 3-1/2 in. on the wall.

Cleaning

The curtain route is laundry. Parachute publishes its liner and its cotton curtain as machine washable; iDesign’s vinyl liner wipes clean. The usual failure is mildew along the bottom of the liner, and the fix is to pull it flat after every shower.

Glass is wiping and squeegeeing. Kohler’s CleanCoat+ coating, published on both doors here, is designed to shed water and soap scum, which cuts the job down but does not remove it. The tracks and jambs need attention too.

Getting in and out

A curtain pulls aside to leave the whole opening clear. A sliding door gives up roughly half of it, because one panel always sits behind the other: the Cursiva’s walk-through is 21-13/16 to 25 in. on a 56-1/8 to 59-7/8 in. opening, and the Levity bypass is 18-1/16 to 21-1/16 in.

That matters if you bathe small children, or if anyone in the home needs room and a grab bar to step over a tub wall.

Weight, fixing and fit

A door is not a one-person carry, and its sheet has fit rules. The Cursiva is “Not for use with cast iron shower bases”. The Levity bypass warns its narrow jambs may not cover the holes an old door leaves. Every door is sold for a width range, not a single size, so measure first. The sliding doors we would buy are here.

Changing your mind

This is the curtain’s biggest advantage. A new color, a new pattern or a fresh liner takes a few minutes and nothing else in the bathroom changes. A door is chosen once. If the look matters to you more than the fixture, that alone may decide it.

Which to choose

A curtain if you rent, bathe children in the tub, want the full opening, or like to change the room. A door if you own, shower rather than bathe, and want a clean glass look with a long warranty. If you are replacing an old door, check Kohler’s jamb note before you order.

If you rent

The curtain, the liner and the vinyl liner all rate Safe on our install rating. Both glass doors are Owner-only: they are fixed to the walls and ledge. What you can change in a rental bathroom is here.
