Smelly bathroom sink water

[Andy Smith]

Hi folks, weird question here. Has anyone noticed water coming from just one location smelling sulfurous? My bathroom sink water has a sulfury odor to it. 2020 3855br, been living in it full time for a bit over a year, started noticing a few weeks ago. None of the other water outlets have this smell. At first I thought it was the drain trap so I took that apart and cleaned it but it didn't make a difference. Shower water, outside kitchen, inside kitchen, convenience center hoses all are fine. Just the bathroom sink seems affected, both hot and cold. Any ideas? Thanks!
