Why 8–12 mm — not a 6 mm cubicle

Thin hypermarket glass flexes, rattles and looks cheap. Thickness is load and lifespan — not marketing.

A stock shower cubicle from a DIY store almost always sits on 5–6 mm glass. On a short, low span that can be acceptable. As soon as the pane is taller and wider, you get flex: the door rattles, the hinge works in bend, seals lose geometry faster.

Tempered 8–12 mm behaves differently. The pane is stiffer, hinges and clamps take the load calmly, closing is quieter. Visually the construction feels more substantial — less cheap flutter, more architectural clarity.

Thickness is not a price-list checkbox. It depends on panel height, door width, opening type (hinged, sliding, fixed), fixing points and hardware weight. What works for a narrow alcove door will not suit a tall corner leaf.

Safety matters too. Tempering is not a badge: if the pane breaks, it fragments into small pieces. Tempering does not replace the right thickness and the right fixings. Thin tempered glass is still thin in stiffness.

Hardware is sized for glass weight. Brass-alloy hinges are designed around 8–12 mm. A heavy hinge on 6 mm, or a light kit on a wide 10–12 mm pane, ends in constant adjustment.

At VIREO, thickness is part of the project — not a “premium upsell”. In the 3D configurator and on survey we read the bathroom geometry and opening scenario first, then lock the specification. A guide price comes early; the exact sum follows the survey.

If you compare us with a hypermarket cubicle, compare more than today’s sticker price: how the door feels a year later, how the edge looks, and whether the construction fits your tiling and geometry — not someone else’s catalogue box.
