What additional items do people usually buy along with a door?

When replacing or installing a door (especially bathroom or interior doors), I’m curious:

What other items did you end up buying after or along with the door?

For example:

• Hardware (locks, handles, hinges)? • Door closers or stoppers? • Frames, seals, or accessories? • Anything you wish you had bought together but didn’t?

Asking from a home improvement / user experience perspective — trying to understand what actually makes door replacement smoother for homeowners in India.

Would love to hear real experiences.
