Which Side of Frosted or Patterned Glass Faces Out?

Frosted and patterned glass are treated on one face only. The other stays smooth. Which way round the panel goes is a real decision, and getting it wrong is annoying rather than dangerous — you live with a surface that is harder to clean than it needed to be.

The principle

Texture catches things. Smooth surfaces do not.

Whatever the textured face is turned toward is what will accumulate in it — water, mineral deposits, grease, fingerprints. So point the textured face away from whatever is dirtiest.

In a bathroom or shower: smooth face toward the water

Melbourne water carries enough dissolved mineral content to leave deposits when it evaporates. On a smooth surface a squeegee clears it in one pass. In a texture, it settles into every recess and builds up into a haze that is very difficult to remove without abrasives — and abrasives on an etched surface will damage it.

So in a shower screen or a bathroom window, the smooth face goes to the wet side. This applies to both frosted and patterned.

In a door or partition: textured face away from the traffic

Here the issue is hands rather than water. Fingerprints on a smooth surface wipe off. Fingerprints in a texture sit in the ridges and need working at.

Fit the patterned face toward the side that gets handled less — usually the inward or less-used side of the door.

Does it change the privacy?

Barely. The obscuring comes from light scattering as it passes through the texture, and that happens regardless of orientation. You may notice a very slight difference in how sharp shadows appear close to the glass, but for practical purposes both orientations give the same privacy.

So this decision is about maintenance, not performance. Decide it on cleaning.

When appearance decides instead

There are cases where you want the texture on the visible side because it is the point:

• Reeded glass on cabinet doors — the reeding is decorative and usually faces out into the room, where it catches light. Cabinet fronts do not get wet, and the occasional fingerprint is an acceptable trade for the look.
• Feature panels — where the texture is the design, not just privacy.

In a kitchen, weigh that against grease. Reeded glass on a cabinet door near a cooktop will collect cooking film in the ridges.

Which face is which

Usually obvious by touch — run a finger over both sides. If it is not obvious, particularly with a fine etch, the treated face is slightly less reflective. Hold the panel at a shallow angle to a light and compare the reflections; the smooth face gives a sharper one.

Tell your glazier

If someone else is installing, say which way you want it before they start. Once a panel is siliconed into a frame, turning it round is not a five minute job.

It is worth a note in the order too — not because we can control the installation, but so everyone is working from the same intention.

Short version

• Wet area — smooth face toward the water
• Door or partition — textured face toward the quieter side
• Decorative cabinet glass — textured face out, if it stays away from grease
