Great points palimpsest. I have a wall mounted faucet but it is with a farm style sink (not a vessel sink). I planned and planned the location of the faucet above the rim of the sink. The end of my spout (where the water exits) is 4" above the rim of my sink. The sink is about 35" at the rim, above the floor. There is a counter at the side that makes the counter height 36". My rough in is about 40" above the floor. I have a tall wainscot so my mirror needed to be mounted higher. It would be marginal for your use, but my DDIL is 5'1" and she didn't complained about it when they visited. If you plan your installation this should not be a problem for you when you mount your mirror. With you being 5'1", your eyeballs will be at about 56-57" above the floor I think. Start there and plan your installation to meet your mirror viewing needs. If you have a large variance of people heights in the home, maybe you could have the vanity step down to your height needs at your sink. Or have 2 vanities of different heights.

I couldn't find the thread. Maybe its only in my imagination. Anyway, IMHO, here are some examples of what I would not want. The wet hands turning off the faucet handles will drip on the counter and constantly need wiping up. A bigger issue if you have hard water: [Contemporary Bathroom[(https://www.houzz.com/photos/contemporary-bathroom-ideas-phbr1-bp~t_712~s_2103) by San Francisco Architects & Building Designers John Lum Architecture, Inc.

Newport Brass makes several models of wall mount tub fillers. This one is 8GPM, which is plenty, as far as I am concerned: Tub Filler I have a similar Newport Brass wall mount that puts out less volume, but is still adequate. Just be aware that, if the spout does not extend far enough into the tub that the water stream hits the bottom, you may get splashback onto the nearby bathroom wall with a spout that is only far enough over the tub edge that the stream hits the upper area of the inner wall of the tub. This is especially true for a high volume valve.

@Beverly: Good point but no, it doesn't. There's an option for 1, 2, and 3 holes. Hence why I went down a rabbit hole of research, lol. :X I think it's definitely feasible but after really thinking about the added work for the contractor to put in an access panel for any future repairs, it's a no. That wall would have been an exterior wall. That plus my partner's hesitation to do something that to him feels "like a restaurant". Huh? Really a bummer because I love the look and can't imagine how satisfying it would be to wipe the counter clean in one fell swoop. Maybe in another life. :-)
