I think it's called sine. Our sales guy really pushed us to go with certain things (like the Cifial faucet)--good quality at good price points, at least when compared to some of the other stuff we liked! We really didn't "have a choice." He said get this, so we did. LOL He's not an advocate of spending more than needed for a guest bath (get the spendier/fancier things for "the baths where you begin and end your day" he's fond of saying), but would steer us away from something if he felt it was garbage or just not worth the $.

You can have a hook, a bar, lay it on the countertop, or my favorite--a large towel ring. The advantages of a hook, bar, or ring are simple----the towel dries infinitely faster, thus minimizing the chances of any habitable bacterial environment. Damp or wet towels on a countertop are far more likely to harbor a nutrient surface for bacteria. Also, if you hang a towel, it will be dryer next time you use it:-) Greg

Not QUITE what you asked but I had hooks for all the towels in my previous house's master bathroom. So much easier and everything dried quickly. DH, wonderful as he may be otherwise, has a pathological inability to hang a towel straight on a towel rod :-) and I think towels on a ring look tidy for about five minutes - the other bath and half-bath had rings which drove me nuts. Unless the ring is fixed in place, if you remove the towel from the ring the ring bangs into the wall (this has been the case with all the towel rings I've had anyway, with a resulting dent in the wall behind) and much of the time it's haphazardly stuffed back into the ring after use, and if you use it while it's still on the ring it looks rather discombobulated afterward unless you're just delicately dabbing your fingertips. :-) Our current half bath has a towel rod at this time and it seems like I'm constantly straightening out a towel that's all crooked. Just put up a hook yesterday in the one full bath so the hand towel no longer has to share a rod with my bath towel. This is MY experience, your mileage may vary.

Thanks, GN Builders and weedyacres. The thought of a hand towel by the toilet is kind of unappealing to me, but maybe once it’s built it won’t feel so close. Weedyacres, the sink is a 40”W trough sink with two faucets. I like the idea of hanging towels in the front cabinet doors, but is there any concern of damp towels hanging on a wood cabinet face? The wood species is sapele, which is similar to teak, it’s used on boats so I guess it is made to withstand moisture 🤔
