You add holes, corner notches and splashback socket cut-outs in the configurator before you order. Online we drill holes from 6 mm to 100 mm, and positions are measured to the centre of the hole. Every hole, notch and cut-out has to be made before the glass is toughened, so decide them all before you order.
What can I add to my glass?
| Feature | What you can order online | How the position is measured |
|---|---|---|
| Hole | 6 mm to 50 mm in 2 mm steps, then 60, 70, 80, 90 and 100 mm | To the centre: X from the left edge, Y from the bottom edge |
| Hole over 100 mm | Tell us the diameter and we price it by hand | As above |
| Corner notch | A square cut from a corner, one per corner, inside corner rounded at 18 mm or more | Width along the top or bottom edge and height along the side, both from the corner |
| Socket cut-out | Splashbacks. Not shower or bath glass, and not offered on mirrors | To the centre of the socket |
How do I give the position of a hole?
X and Y are measured to the centre of the hole: X from the left edge, Y from the bottom edge. On shower glass, the left edge is the left as you look at the glass from outside the shower. Keep the diameter and the centre separate: a centre position is not the clear distance from the edge of the hole.
The smallest hole we drill is the thickness of the glass. On 10 mm glass, for example, the configurator does not offer 6 mm or 8 mm holes.
Does the configurator check the spacing?
Yes. It checks that holes are not too close to each other and that no hole falls outside the glass. If one fails, it tells you why, with the numbers, for example "Holes must be at least 36 mm apart, edge to edge."
How does a corner notch work?
A corner notch, shown as "Square cut (corner notch)", removes a rectangle from a corner of the glass, one per corner. The inside corner is rounded: 18 mm is the smallest radius we cut, and you can choose a larger one, up to the size of the cut.
A fixed bath screen takes one corner cut, or two on the same side edge (its wall edge), never one on each side. Hinged panels take their hinge cut-outs only, not corner notches.
Can I have a socket cut-out?
Yes, on splashbacks. Measure to the centre of each socket or switch from the same two edges every time, usually the left-hand end and the worktop, and give the size of the plate as well. Shower and bath glass does not take socket cut-outs, and the mirror configurator does not offer cut-outs.
Why must everything be done before toughening?
Toughened glass cannot be cut, drilled or notched once it has been made. Every hole and cut-out is finished first, then the glass is toughened. See toughened, laminated and annealed glass.
What is the 700 mm rule for fixed shower and bath panels?
| Fixed panel width | Preparation and support |
|---|---|
| Up to 700 mm | U-channel only; no holes and no "add hole" option |
| From 701 mm | Two automatic Ø20 mm holes, 200 mm from the bottom edge and 200 mm from the top edge, centred 33 mm from the wall edge; two SWGC83300 brackets plus U-channel |
The channel is SWCH20X15X20 for 10 mm glass and SWCH15X15X15 for 8 mm. The rule covers the fixed panels of bath screens, walk-ins and hinged enclosures; doors are unchanged. It does not apply to sliding enclosures, the free-standing walk-in, the single hinged bath panel, the folding bath screen or a single door between two walls. A panel with no wall edge gets no bracket hole, and on these panels you cannot add holes of your own at any width.
What if a bath screen has a corner cut on the wall edge?
Each hole stays 200 mm from the top or bottom edge, even with a corner cut at that end. It moves only if the cut swallows the hole centre or the hole would break into the cut's edge; then it goes 200 mm from that end of the remaining straight wall edge. Check the final drawing, and the fixed-panel bracket guide for a worked example.

Questions we get asked
Can you drill a hole bigger than 100 mm?
Yes. Tell us the diameter in the configurator and we price that hole by hand.
Can I add my own holes to a narrow fixed shower panel?
No. A fixed panel up to 700 mm wide under the 700 mm rule is held by U-channel only, with no holes and no option to add one. Wider panels get the two bracket holes the rule sets.
Can you drill my glass after it is toughened?
No. Toughened glass cannot be drilled, cut or notched once it is made, so every hole is drilled first.
