But water in rest of house

Hi DD

Almost impossible for all water to stop working in a bathroom unless someone shut off water to the hot and cold water supplying that bathroom or everything gets clogged somehow.

Is water flowing to the toilet or the shower/tub? If so, then the sink faucet aerator is plugged up and needs to be cleaned out and you should be all set here... ;)

If water really isn't flowing to all fixtures and no one has shut anything off then perhaps all things are clogged and you'll need to disassemble the fill valve to the toilet, the shower head to the shower, the tub valve, and the sink aerator... maybe?

Clean the aerator at the sink and let me know what happens, OK?
