How can I improve this bathroom sink without renovating?

I’m looking for ways to improve the look of this bathroom sink area without replacing everything.

The sink has visible stains, the faucet feels outdated, and the mirror setup looks basic.

I can’t change the whole vanity, so I’m mainly interested in cosmetic, budget-friendly upgrades (new faucet, refinishing the sink, better lighting, mirror ideas, etc.).

I’m aiming for a clean, modern, neutral look.

What would you suggest?
