Shower doors and glass: sliding, pivot, frameless, or a curtain

A shower door is the part of a new shower people look at most and think about least, and it is chosen late, often after the walls have been ordered. Which kind fits your bathroom depends on three things that have nothing to do with taste: how much floor there is outside the shower, who has to get through the opening, and whether the wall system you picked already comes with a door. This page takes them in that order.

The four kinds of door, and the curtain

• A sliding door, also called a bypass door: two panels that pass each other on tracks. It needs no swing space, which makes it the usual answer in a small bathroom. The trade is that only half the opening is ever clear, and the bottom track collects water and wants cleaning.
• A pivot door: a single hinged panel that swings open. It gives the full opening and a cleaner look, and it needs clear floor outside the shower to swing into, which is what rules it out in a tight room with the toilet or the vanity in the arc.
• A frameless door: heavy tempered glass carrying its own weight through hinges and clips, with no metal frame around the panels. The clearest look, the highest price, and the one that depends most on the walls being true, because there is no frame to absorb a discrepancy.
• A semi-frameless door: framed around the perimeter with an unframed door panel. It keeps much of the open look while tolerating ordinary wall conditions, and it sits between framed and frameless on price. The sliding door in the Acrylic kit is this kind.
• A curtain and rod: the standard on four of our six wall systems, and not a consolation prize. It is the easiest of all of these for a walker, a wheelchair or a caregiver, because it simply moves aside, it costs the least, and it is the one you can change on a whim. A weighted curtain kit made to keep water inside a no-step pan is a priced option for the Bestbath system.

Which of the six wall systems come with a door

Two do. The Acrylic kit is supplied with its own semi-frameless sliding glass door, made to fit the kit, and Castico includes a matching door. On Bestbath, Palisade, Trinity and Transolid the standard is a curtain and rod, and glass is a priced upgrade: a semi-frameless sliding door, two clear panels that slide past each other, or a frameless door, both selectable in the Estimate Builder. The wall systems comparison puts that in a table beside everything else that separates the six, and the what is included page explains why comparing two starting prices without checking which contains a door is comparing two different things.

When a curtain is the better answer

More often than the showroom suggests. A curtain is the right call when somebody uses a walker or a wheelchair, because a door's track or sill is one more thing to cross and a swinging panel is one more thing to manage with one hand. It is the right call when a caregiver helps from outside the spray, because a curtain opens the whole width and a door opens half of it or swings into the helper. It is the right call in a very small bathroom where a pivot door cannot swing and a slider's track will annoy you every day, and it is the right call when the bathroom has to be back in use in a day, because a made-to-fit glass door adds a return visit. Budget is a reason too, and not an embarrassing one. The packages ship with a curtain because for many households it is simply the better fitting.

Why the glass comes after the walls

Shower glass is tempered, which means it breaks into small blunt pieces instead of shards, and it also means it cannot be cut or drilled once it has been made. The federal safety glazing standard that defines tempered glass is set out on the page on windows and glass in a Central Ohio house. So a door that is made to fit your opening is measured against the finished walls rather than off a drawing, and fabricated to that size. On the three wall systems where glass is an upgrade, the walls go in, the opening is measured, and the door follows on a short return visit while the shower is already usable behind the curtain and rod. It is the most common reason a finish date moves and the least alarming one; the timeline page covers it. The Acrylic and Castico doors are made to their own kits, so they go in with the walls.

Which way a door should swing

Outward, in a home where somebody might one day need help in the shower. A door that swings out can be opened from outside even if the person inside is against it; a door that swings in cannot. Hinged doors that swing both ways exist and are worth asking about. A pivot door also needs its whole swing arc clear of the toilet, the vanity and the bathroom door, which is a measurement to take before falling for one in a photograph.

A door on a shower with no step

A curbless shower does not need a door to keep the water in. What does that is the slope of the floor to the drain and the waterproofing under it, and a curtain does the rest in many bathrooms, especially with a linear drain along one wall so the whole floor falls one way. A glass door can be fitted to a curbless shower, with a seal along its bottom edge doing part of the curb's job, and it looks cleaner; the curbless page explains the construction underneath. Which suits your room is a walkthrough question rather than a rule.

Glass that stays clear

Squeegee it after each use, which takes ten seconds and prevents most of the hard-water scale that makes glass look cloudy. Clean it with a mild non-abrasive cleaner or diluted white vinegar, keeping the vinegar on the glass and off the wall panels. Low-iron glass stays clearer at the edges because it lacks the green tint of ordinary glass, and a factory protective coating sheds water and scale so the glass needs less work, though it is not maintenance-free. A sliding door has a bottom track that collects water and wants a wipe. The cleaning and care page has the rest of the list.
