Plaster Crack - Thoughts, Reasons, Fixes?

[schwarz_lauren]

Any thoughts here? Common causes and best practice fixes?

1yr old plaster, hairline crack starting at tile edge, down approx 18inches.

Can you circle the crack?. I cannot see it through the water reflections.

It’s cosmetic. Leave it alone. Nothing you do will make it any better but anything you attempt has a good chance of making it look worse. Plaster can develop shrinkage cracks. It happens.

I agree with Matt. That is a cosmetic shrinkage crack. Ignore it if it does not get bigger.
