Shower Screen Glass Thickness Explained (6mm vs 10mm)
Shower screen glass comes in 6mm, 8mm and 10mm toughened thicknesses. 6mm is used for framed and semi-frameless screens where the frame supports the glass, 8mm is a mid-point for larger semi-frameless panels, and 10mm is standard for frameless screens because it stays rigid without a frame. Thicker glass costs more and feels more solid, and the right thickness depends on the style and panel size. Glazing Adelaide connects you with vetted local specialists who spec the correct thickness and quote it clearly.
Key takeaways
- 6mm: framed and semi-frameless, where a frame supports the glass.
- 8mm: larger semi-frameless panels needing more rigidity.
- 10mm: the standard for frameless, staying solid with no frame.
- Thicker glass is more rigid and feels premium, but costs more per panel.
- Panel size and style, not preference alone, dictate the right thickness.
6mm, 8mm and 10mm: where each is used
6mm toughened glass is the workhorse of framed and many semi-frameless screens. Because an aluminium frame or fixing channel carries the load, the glass itself does not need to be thick to stay stable. It keeps the price down and suits standard-sized doors and panels over baths and in compact showers.
8mm sits in the middle and comes into play for larger semi-frameless panels. When a fixed panel or door gets wide enough that 6mm would start to flex, stepping up to 8mm adds rigidity and a more solid feel without the full cost of 10mm.
10mm toughened glass is the standard for frameless screens. With minimal brackets and no frame to support it, a frameless panel relies on the glass itself to stay rigid, and 10mm provides that stiffness. It is also what gives frameless screens their substantial, high-end feel.
How thickness affects rigidity and feel
Rigidity is the practical reason thickness matters. A thin panel in a large opening flexes and can rattle or bow, which feels cheap and, over time, stresses the fixings. Matching the thickness to the panel size keeps the glass sitting solid and quiet.
There is a tactile difference too. Thicker glass feels more substantial when you open the door, and a 10mm frameless panel reads as premium in a way a 6mm framed door does not. For many buyers, that heft is part of what they are paying for in a frameless upgrade.
Thickness is not a free upgrade you apply everywhere, though. On a small framed screen, 10mm glass is overkill that adds weight and cost for no real benefit, because the frame is doing the structural work. The goal is the right thickness for the job, not the thickest available.
What thickness does to the price
Glass is priced by area and thickness, so 10mm costs noticeably more per square metre than 6mm. That difference is a major reason frameless screens cost more than framed and semi-frameless: you are paying for both thicker glass and the heavier hardware it needs.
The heavier hardware compounds it. Thick frameless panels need stronger hinges and brackets rated to carry the weight, and those cost more than the lighter fittings used on 6mm framed screens. So moving up in thickness moves up the whole bill, not just the glass line.
The sensible approach is to let the configuration set the thickness rather than chasing a number. Glazing Adelaide matches you with vetted local specialists who recommend the correct thickness for your style and panel size, then quote it clearly so you can see exactly what the glass is costing.

Frequently asked questions
It is not better in every situation, it is right for different jobs. 10mm suits frameless panels that need to stay rigid without a frame, while 6mm is ideal for framed screens where the frame provides the support.
Yes. 10mm glass costs more per square metre than 6mm and needs heavier hardware to carry it, so choosing thicker glass raises both the glass and the fittings cost.
10mm toughened glass is the standard for frameless screens because it stays rigid with only minimal brackets holding it. A specialist confirms the exact spec based on your panel sizes.
