Hi Everyone
So I recently bought a house and only noticed this damage in the ensuite during the pre-settlement inspection on the architrave/door:

The water seems to be coming from the shower (or when the shower is used) as it is one of those shower sections where it is just a glass wall (similar to how it is in some hotel rooms)
There doesn't seem to be a lot/any swelling (compared to other images i've seen online) so I was thinking perhaps just a sandown of the areas + some paint would be sufficient to fix this?
Just wanted some opinions before committing to replacing the entire door or replacing the architrave
Thanks
D
