It isn’t really common, but at times you might want to remove a WordPress theme. For example, if you were editing a theme manually and have to revert back to the unedited theme, then you may delete the modified theme and then reinstall the theme as you originally did.
Deleting a WordPress Theme
With the following steps you can delete a WordPress theme:
Step 1: Begin by logging to the WordPress Dashboard.
Step 2: Navigate to Appearance and then themes.
Step 3: If the theme you want to remove is already in use, simply activate a different theme

You might receive a pop up message which requests you to verify that you’d like to remove the them. If you receive this, simply press on OK.
You should then get a confirmation which says your theme was deleted.
