I have a shower drain that looks like this:
And the "drain cap", if that's even the right term, looks like this:
The drain cap is broken. I would like to replace the whole drain, but having no experience in DIY, that might be too big of a task.
So I might want to replace only the "cap", however I do not find any on the hardware store websites or amazon. Is my cap a special one or is it something standard? If it's pretty standard, what are the keywords I should be looking for when shopping for one?
