Is this a PR or an actual guest bathroom? I do not like actual towels in PRs I use disposibles there since I never like to dry my hands on a towel someone else used and even less so in this time.Something like this .If it needs a towel holder then why not just a pretty knob insted of a rod.

This room was done in 2019, so that exact towel rod most likely isn’t available now. Have you tried searching ’antique brass towel rods’? I saw some nice ones.

This is kind of interesting … their Instagram shows the above bathroom from 2019, then this one from last year. It looks like the same bathroom, redone, but the door is different, too. Or they put this mirror in every bathroom they do. :D

I don't know....but THAT mirror is GORGEOUS! I'd be looking for the matching towel bar too. ♥ As a last resort, I'd make do with these towel bar ends and buy twisted metal stock, paint it the goldish color.....and it would blend. Link

Or you can take a larger towel bar and hack saw it to the length you want...
