Condensation on Coated Shower Glass: Do Not Infer Anti-Fog Performance from Beading
Water repellency and visibility during condensation are different questions. Evaluate the actual product and conditions instead of turning a beading demonstration into an anti-fog promise.

State the observation clearly
Record whether the issue is condensation during use, dried water marks or residue after cleaning. These occur at different stages and should not share one diagnosis. Identify the pane, exposed face and coating history.
Check the product claim
Use the current instructions and intended functions of the exact treatment. A nano or hydrophobic description does not by itself establish an anti-fog specification. Ask the technical supplier when that function is important to the project.
Use a relevant evaluation
If a supported trial is appropriate, define the actual visibility question and representative conditions. Keep cleaning and surface history recorded. A water-drop photograph on a dry pane does not reproduce the full shower-use question.
Keep maintenance and room conditions visible
Follow the glazing and coating care guidance and record any changed bathroom routine. Address room or enclosure issues through the appropriate provider. Report the observed result without extending it to every humidity or temperature condition.
Frequently asked question
Does stronger water beading automatically mean better anti-fog performance?
No. The beading observation does not establish that separate function. Confirm the exact product claim and a suitable evaluation method.
