Shower Glass
Shower Glass near you
A shower screen looks like a glass product and is really a waterproofing one. Every bracket, every channel and every hinge plate is fixed into a surface the ABCB Housing Provisions require to be waterproof: the walls of the shower area not less than 1800 mm above the floor substrate, the floor including any hob or step-down, the wall and floor junctions, and, in the code's own words, penetrations within the shower area. Drilling a hole in that membrane is the single most consequential thing that happens on installation day.

The glass has a second peculiarity. Frameless and semi-frameless screens leave edges exposed, and the Provisions treat that as a distinct case: in a bathroom, ensuite or spa room, panels or doors with any edge exposed must be toughened safety glass with a minimum nominal thickness of 6 mm, within the wider rule that catches all glazing below a sight line two metres above the floor, the bottom of the bath or the shower base. Toughened glass is also the only glass in a house that can fail without being struck, which is why edge protection during handling and installation matters so much.
So the two questions to ask a supplier are not about finishes. They are what the screen will be fixed into and how those penetrations will be sealed, and what grade and thickness of glass is going in given how the panels are edged. Get both answered in writing before the panels are cut, because toughened glass cannot be trimmed afterwards.
Framed, semi-frameless, frameless and walk-in
The configuration decides the hardware, the glass thickness, the number of penetrations and how the screen will behave in five years. It also decides how much the bathroom has to be built around it, which is why it is a decision for the design stage rather than the fit-out.
- Fully framed: every edge is captured in aluminium, the glass can be thinner, the frame carries the load and the seals are mostly in the frame rather than in silicone.
- Semi-frameless: framed where it is fixed and open on the door, which reduces the visual bulk while keeping most of the structure.
- Frameless: thick toughened panels on brackets and hinge plates, the cleanest look, the heaviest glass, the fewest but most critical fixings.
- Walk-in or fixed return panel with no door, which relies on the layout to contain water rather than on a seal.
- Over-bath screens, single or folding, which have the extra problem of a fixing line along the wall above an edge that moves.
- Sliding or bypass doors, which suit a narrow bathroom where a swinging door has nowhere to go and keep the wet face inboard.
- Curved and custom shapes, which are made to order and cannot be adjusted on site, so the set-out has to be right first time.
Glass grade, exposed edges and the mark that proves it
Bathrooms are one of the strictest places in a house for glazing. The Housing Provisions capture all glazing in kitchens, bathrooms, ensuites, spa rooms and the like, including shower doors, shower screens, bath enclosures and their associated windows and doors, where the lowest sight line is less than 2.0 m above the highest abutting finished floor level, the bottom of the bath or the shower base. In practice that is the whole screen.
The exposed-edge rule is the one that bites on a frameless job. Where a panel or door has any edge exposed, the Provisions call for toughened safety glass with a minimum nominal thickness of 6 mm, rather than the framed-panel route. That is why a frameless screen is made from thick toughened panels and why a supplier who quotes thin glass for a frameless design has not read the job properly.
You can verify what was delivered. Safety glazing material has to be marked, either by permanent etching or by a label that cannot be reused once it is removed, and the mark identifies the standard the glass was tested to, the maker or supplier, the grade, the nominal thickness and the type. Find it on each panel before the installer leaves, and keep a photograph with the house records.
Fixings, penetrations and the membrane you cannot see
By the time a screen is measured, the waterproofing is already buried under tile. The Provisions require the shower area walls to be waterproof not less than 1800 mm above the floor substrate, the floor including any hob or step-down to be waterproof, wall junctions and joints within the shower area to be waterproof not less than 40 mm either side of the junction, and penetrations within the shower area to be waterproof. A screen installer works through all of that with a drill.
Good practice is therefore about minimising and sealing. Ask how many penetrations the design needs and whether any can be avoided, whether fixings can land outside the wettest zone, and exactly what is used to seal each hole before the plug and screw go in. A silicone bead smeared over the outside of a bracket afterwards is not the same thing as sealing the hole itself, and it is the difference between a bathroom that stays dry and one that rots a stud quietly for three years.
Walk-in and unenclosed showers add a further requirement worth knowing. Where the shower is not enclosed, the Provisions call for a waterstop installed not less than 1500 mm horizontally from the shower rose, with junction waterproofing to match, or the whole floor waterproofed as the alternative. If your design is heading towards an open screen with no door, that detail belongs in the drawings, not in a conversation on the day.
Why toughened glass sometimes shatters with nobody near it
Toughened glass is made by putting the surface into compression, which is what makes it strong and what makes it break into small blunt pieces. The same process means a tiny flaw deep in the pane can, months or years later, relieve that stress all at once, and the panel comes down without anybody touching it. It is uncommon, it is well known in the trade, and it is the reason a shower screen should never be treated as a handrail.
The failures that are avoidable nearly all start at an edge. Toughened glass cannot be cut, drilled or ground after treatment, so any nick taken during transport, storage or installation is permanent, and the panel will eventually find it. Ask how panels are delivered and stored on site, insist that nothing is stood on a bare concrete floor, and check each edge with a fingertip before it goes up.
Day to day, the other problems are hardware rather than glass. Doors drop because hinge plates loosen against a tiled wall, seals go hard and stop wiping, magnetic catches wear, and rollers on a slider fill with soap and grit. None of those are emergencies, but a door that is dragging is also loading the glass in a way it was not designed for, so fix it early.
Keeping the glass clear and the seals working
- Squeegee the panels after each shower, since the mineral film left by drying water is what eventually etches the surface permanently.
- Ventilate the room properly and for long enough after use, because an unventilated Australian bathroom in summer grows mould in the silicone within weeks.
- Clean with a mild solution and a soft cloth, and keep abrasive pads and strong acids away from both the glass and the hardware finish.
- Replace wiper and bubble seals when they harden, which is a cheap part and the usual cause of water reaching the floor outside.
- Check hinge and bracket screws once a year, and have anything that is moving in the wall looked at rather than simply tightened harder.
- Cut back silicone that has blackened right through and have it redone, instead of running a new bead over the old one.
- Never hang a towel, a rail or body weight on a frameless panel or its door, which is exactly the loading it was never designed for.
Replacing a panel, or replacing the screen
A broken or damaged panel can often be remade to match, and on a framed or semi-frameless screen that is usually the sensible route, provided the frame is straight, the wall channel is sound and the hardware is still available. On a frameless screen the panel is the structure, so a replacement has to reproduce the original toughening, thickness, edgework and hole positions exactly, since nothing can be adjusted after manufacture.
The case for a whole new screen is usually made by the room rather than the glass. If the tiles are being replaced, if the hob is being removed for a step-free shower, if the screen is moving because the substrate behind the tile has softened, or if the existing glass carries no safety glazing mark at all, then the screen is coming out anyway and a like-for-like replacement is false economy.
There is one more trigger worth naming. If water has been getting behind the screen for a long time, the important work is not the new glass but finding out what the moisture has reached. Have someone open up enough to look before the new screen is fitted, because a beautiful frameless panel bolted to a wet, soft wall is a repair that will be done twice.
Who is responsible when a new bathroom leaks
Shower leaks are the classic multi-trade dispute, because the waterproofer, the tiler and the screen installer each did their part and the water does not say whose fault it was. The way to avoid that argument is to fix responsibility before the work, not after: get it in writing who is sealing the penetrations for the screen, and who warrants the waterproofing of the shower area as a whole once the screen is fixed through it.
Under the Australian Consumer Law the screen is goods and the installation is a service, so the glass and hardware must be of acceptable quality and fit for a purpose you made known, and the work must be done with acceptable care and skill. A screen that leaks onto a timber floor, or a door that has dropped so far it will not close, is not a cosmetic complaint.
Domestic building work also attracts statutory warranties and, above state thresholds, insurance under your state's home building scheme, and the rules differ between New South Wales, Victoria, Queensland, Western Australia and the smaller jurisdictions. LokalMatch is the front of that process: you describe the shower once, with the opening dimensions, the configuration you want, whether there is a hob and whether the room is being retiled, and installers covering your postcode contact you. Those businesses pay for the requests they receive. LokalMatch does not install shower screens, does not set or quote prices, and does not vet, rank or recommend anyone.
Shower Glass: frequently asked questions
What thickness of glass does a frameless shower screen need?
Where a panel or door in a bathroom, ensuite or spa room has any edge exposed, the Housing Provisions call for toughened safety glass with a minimum nominal thickness of 6 mm. Frameless screens are made from thicker toughened panels than that in practice, because the glass is also carrying the door and the hardware.
How do I know the screen is actually safety glass?
Look for the mark. Safety glazing material must be marked by permanent etching or by a label that cannot be reused once removed, identifying the standard it was tested to, the manufacturer or supplier, the grade, the nominal thickness and the type of glass. Find it on each panel before the installer leaves, and photograph it for your records.
Can a shower screen really explode on its own?
Toughened glass can fail spontaneously, long after installation, because the process that makes it strong holds the pane in tension internally and a small internal flaw can release it. It is uncommon. Most avoidable failures start with an edge chipped during handling, since toughened glass cannot be cut or ground once treated.
Will drilling the tiles for the screen cause a leak?
It can, which is why it matters how it is done. The Housing Provisions require the shower walls to be waterproof to at least 1800 mm above the floor substrate and require penetrations within the shower area to be waterproof. Ask how many penetrations the design needs, whether any can sit outside the wettest zone, and exactly how each hole is sealed before the fixing goes in.
Do I need anything special for a walk-in shower with no door?
Yes. For an unenclosed shower the Provisions require a waterstop not less than 1500 mm horizontally from the shower rose with matching junction waterproofing, or the whole floor waterproofed instead. That is a design decision that belongs in the drawings before tiling, not something to resolve when the screen is measured.
My frameless door has dropped and drags. Is that serious?
Serious enough to fix promptly. A dragging door usually means hinge plates have loosened against the wall or the panel has shifted, and it puts loading on the glass that the design never allowed for. Have the fixings inspected rather than simply tightened, since movement in the wall can mean the substrate behind the tile has softened.

What affects the cost of shower glass
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Number, size and style of windows or doors
- Frame material and glass options
- Full-frame replacement or insert
- Repairs to rotted framing or sills
- Interior and exterior trim and capping
- Access, including upper floors
How to compare glass installers before you hire
- Look for an installer who measures on site and explains how the new window or door will be sealed and flashed.
- Ask whether the quote is for a full-frame replacement or an insert, and why they recommend it.
- Compare quotes on the same product type, glass options, installation method and interior and exterior trim.
- Ask who handles warranty issues: the installer, the manufacturer or both.
- For garage doors, choose a technician trained on springs and openers, since that work can be dangerous.
Questions to ask glass installers before you hire
- Will you replace the full frame or install an insert, and what's the difference for my home?
- How will you insulate and seal around the new units?
- Is interior and exterior trim included in the price?
- What does the manufacturer's warranty cover, and what does your installation warranty cover?
- How long will it take for the products to arrive once I order?
- Will your own crew do the installation?
When to call a pro for shower glass
- Drafts, condensation or fog between the panes
- Windows or doors that stick, won't lock or let water in
- A garage door that's off track or has a broken spring: don't try to force it, and call a garage door technician.
Shower glass permits and local rules
Some shower glass work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
