Both are very nice.

The first photo looks like one side is for a left-handed person and the other for a right-handed person due to the counter space layout. But, each person has dedicated storage with side-access drawers.

The second one also looks nice, but do you like having dedicated drawers at the bottom with shared drawers in the middle? Given that the sinks are mounted above the counter, I assume those drawers are pretty low?

As for the middle stack of drawers between the two, is there an option for that section to have a hutch on top for more storage? Only if you need the extra storage, of course.

I think I'd like the extra added space to each side. That could accommodate a waste basket, hamper, stool, etc, etc. I have about 12" on one side of my vanity and have a towel tree there. The other side is my toilet.

I hear you when you call your bathroom an "aisle", mine is like that too. I have 2 pocket doors though, one at each end. My room is 8' x about 10' with shower on one 10' side and instead of a toilet, I have a built in cabinet set that surrounds a small stacked W/D. My toilet is next to my vanity which is 60" long. This is the other side along the 10' wall. It is a common use bathroom and is accessible from a small bedroom and at the other end, a hallway. It almost functions as a hallway itself, lol, "my bathroom in a hall".

I think I will go for the shorter vanity and leave more space for ease of cleaning. I believe our final choice is this one, it is 84" so will leave us 10" on each end. I also verified the legs are 5 & 7/8" tall so plenty of space for the Roomba to fit (it needs 4") to my joy. This is our master bath opening off the bedroom.

We are also doing the guest bath, it currently has a 66" vanity with the toilet beyond and then tub across the end. The tub is staying here just doing the floors and vanity, here it is now:

and for this room we picked a 48" vanity to center under the light fixture, which will leave 9" between the vanity and the wall on the left and an additional 9" of space between the vanity and toilet, or we may be able to sneak the vanity an inch or 2 off center to the light to give 10-11" between the vanity and wall. It will provide space for a towel ring to hang nicely, especially since the vanities are shorter on the ends.

Now the question is the vessel sink model - DH immediately picked this version and loves the look of the vessel sinks. However the vessel sink version is actually a few inches shower at the counter (28.13" on short sections and 35" to top of vessel sinks) than the sunken sink version (31.63" H on the side/center areas and 31.63" in the sink areas. We would actually prefer a height closer to 33-35" for the counter, perhaps we could switch our the legs with something taller. My other concern with the vessel sinks is the square/flat bottom and the fact that DH's shaving whiskers will tend to linger, while the sunken sinks are rounded toward the drain:

I really like my undermounted sink, so easy to clean. I'd vote for a smooth surface with undermounted sink. But the height would be considered too.

Me too, enduring - now to convince DH :)
