You really need to make sure that you can get your hands under those faucets easily. We have a vessel-type sink setup in one bathroom, and I think the basin drops about 5" in depth, so it's pretty shallow. We do have to be careful about splashing. The faucet on ours actually is mounted inside the sink to help with the drips. To mount 18" apart for a 30" sink is tight. You have just 6" on either side to prevent splash-out. The waterfall-type faucets tend to splash more than ones with an aerator. If you can get a basin with mounts for faucets inside the sink, that will help, but it's a little harder to find those styles than the straight basins. Look at Elkay's "Mystic" river sinks. Those are quite unique and might give you an extra option.

I had this set up in my old masterbath. It was a 36" trough with 2 faucets and they were 18" apart but they also had 9" to each side. In your scenario you will only have 6". I think there will be splashing.

Have you thought about doing a vanity top trough sink and eliminating the wood completely? Duravit makes a trough vanity top with 2 faucets it comes in two lengths and there are other makers too.

There is a reason that the smallest 2 user vanity is suggested to be 60”. To be able to have a single sink that two people can use simultaneously, two people have to be able to stand in front of it. Otherwise you have added complexity and expense, with no return. Additional storage is a better option than a trough sink in a bath not big enough for a double vanity.

@Aglitter @User @localeater Thank you so much for the helpful advice!! I really appreciate it.
