Choosing a bathroom door feels like the last decision in a renovation, but it shapes everything that came before it. Get it wrong and you lose usable floor space, block a fixture you need to reach, or end up with a door that just does not suit the room. Get it right and the whole bathroom clicks into place.
This guide covers the main types of bathroom sliding doors we carry at Glassit, what glass options are available across each type, and how to work out which door actually fits your layout. Whether you are fitting out a compact ensuite or a spacious family bathroom, there is a sensible answer here.
Why Sliding Doors Work So Well in Bathrooms
A hinged door needs a swing arc. In a bathroom, that arc is often 70 to 90 centimetres of floor space that cannot hold a vanity, towel rail, or storage unit. In a small ensuite, it can make the whole room feel cramped before you have even walked in.
A sliding door removes that problem entirely. The panel moves along a track and stays flat against the wall, so the floor space in front of the opening stays clear. That is a meaningful gain in any bathroom, and in compact ensuites it is often the reason the layout works at all.
Beyond the practical side, sliding doors tend to give a bathroom a cleaner, more considered look. There is no door handle swinging into the space, and when the door is open, it sits flush and out of the way.
The Single-Panel Sliding Door (Also Called a Barn Door)
A single-panel sliding door, often called a barn door, is one panel on a wall-mounted track. It slides to one side to open and sits flat against the wall when not in use.
The track mounts on the outside of the wall, so no wall cavity work is needed. That makes it a practical choice for new builds and existing bathrooms alike, especially where renovation disruption needs to stay low.
It is one of our most popular bathroom doors at Glassit, and most people who choose it do so because it solves a space problem without adding complexity.
Our barn sliding door is built with an aluminium frame and 6.38mm laminated safety glass. It is available in clear, obscure, or mirror glass finish on one or both sides.
The one thing to plan for is wall clearance. The panel needs an unobstructed stretch of wall equal to its own width.
If there is a light switch, towel rail, or corner unit in that zone, those need to move before the door goes in. It is worth mapping this out early in the process.
The Standard Patio Sliding Door for Bathrooms
A patio-style sliding door uses two panels in a shared aluminium frame: one fixed, one sliding.
Most people associate this format with large external openings, but it works well inside a bathroom too, particularly where the opening is wider or a more structured look suits the overall design.
The two-panel format gives you a larger glass area, allowing more light to move between rooms.
With obscure glass, you keep full privacy without blocking that light. With a mirror panel on one face, the door becomes a full-length mirror on the outside. That is a practical bonus where the bathroom connects to a bedroom or dressing area.
Our patio sliding doors are available in the same glass options as the rest of our range. If you are working with a wider opening or want a door that feels more architecturally considered, this is the format to look at.
The Aluminium Hinged Door
A sliding door does not suit every layout. Where wall space on both sides of the opening is already occupied by fixed fittings, or where the wall configuration simply does not leave a clear run for a panel to slide into, a hinged door is often the more practical answer.
Our aluminium hinged door is built to the same standard as our sliding range, using 6.38mm laminated safety glass in the same aluminium frame system.
It is available in clear, obscure, or mirror glass on one or both sides. It swings on a fixed aluminium hinge and handles daily use reliably.
The key question with a hinged door is clearance for the swing. The door needs room to open, either into the bathroom or away from it. In a generously sized bathroom this is rarely a problem, but in a tight ensuite it is worth working out exactly where the arc lands before committing to this option.
Glass Options Across All Door Types
Across every door type we carry, the glass choice is yours. Whichever door suits your layout, you can specify the glass finish that fits your privacy and style requirements.
Clear glass
Clear glass transmits light fully and gives the most open, connected feel between spaces.
It works well where privacy is less of a concern, or where the bathroom has no direct sightline from a living area. It also shows off the aluminium frame and hardware clearly.
Obscure glass
Obscure glass, sometimes called frosted glass, diffuses light without blocking it. Visibility through the panel is eliminated, but the room still benefits from natural light passing through.
This is the most common choice for bathroom doors across all layouts. It is available on one face or both, and if you are unsure which glass to specify, it is almost always the right starting point.
Mirror glass
Mirror glass reflects rather than transmits. On one face, the door functions as a full-length mirror on the outside while remaining a standard glass panel on the bathroom side. On both faces, both sides are reflective.
This works particularly well for ensuites alongside a bedroom or dressing room. Our ensuite sliding door with mirror is built around exactly this idea.
Which Door Is Right for Your Bathroom
Here is a straightforward way to think through the decision.
If you have a compact ensuite or small bathroom with clear wall space on at least one side of the opening, the single-panel sliding door is almost certainly the best fit. It saves the most floor space and keeps the room looking uncluttered.
If you have a wider opening or want a door that fills more of the wall with glass, the patio sliding door gives you more surface area and a more architectural result.
If your wall space on both sides is restricted by fixed fittings, and the bathroom is large enough to accommodate a swing arc comfortably, the aluminium hinged door is the practical solution.
For the glass finish: start with obscure unless you have a specific reason to choose otherwise. It suits almost every bathroom layout and handles privacy without any trade-off.
Frequently Asked Questions
Does a barn door give enough privacy in a bathroom?
Yes, as long as you choose the right glass. Our barn sliding doors are available with obscure glass, which diffuses light completely while still allowing it to pass through. Mirror glass on the outside face adds another layer since it is fully reflective from that side. Clear glass is the only option we would not recommend for a bathroom where privacy matters.
How much wall space does a single-panel sliding door need?
The panel needs a clear stretch of wall at least equal to the width of the door itself. So a 900mm door needs 900mm of clear wall beside the opening. Any switches, towel rails, or fittings in that zone need to be repositioned before installation.
What is the difference between a patio sliding door and a barn door?
A barn door is a single panel that slides along a track mounted on the face of the wall. A patio sliding door uses two panels in a shared aluminium frame, one fixed and one sliding, with a bottom track and top rail. The barn door needs clear wall space beside the opening; the patio door stays within its own frame footprint.
Is a sliding door or a hinged door better for a small bathroom?
A sliding door almost always works better in a small bathroom. A hinged door needs 70 to 90 centimetres of floor space to swing open, which limits where you can place other fixtures. A sliding door uses no floor clearance at all, keeping every centimetre of the room usable.
Can I get mirror glass on just one side of the door?
Yes. All our doors with mirror glass can be specified with the mirror on one face only. The outside face becomes a full-length mirror while the inside remains standard glass. You can also have mirror on both faces if that suits your layout better.
What type of glass do you use in your bathroom doors?
We use 6.38mm laminated safety glass across our entire door range. If the glass is ever broken, it holds together rather than shattering into sharp pieces, which is an important safety consideration in any bathroom.
Do I need to organise installation myself?
No. We handle professional installation for every door we supply. Once you confirm your order, our team books a time and takes care of the full installation from start to finish.
Which glass finish should I choose if I am not sure?
Go with obscure glass. It suits the widest range of bathroom layouts, handles privacy without any compromise, and works with every door type we carry. You can always discuss other finishes with us before ordering if you have something specific in mind.
