I really like the vanity - I think the buyers will focus on the color not the legs. Yes, the space underneath can be a pain to keep clean but it does make a handy spot for storing a bathroom scale. I love the vanity color!
If I were to install the vanity, I would prop it on simple wooden supports and put a nice baseboard to cover them. Paint that baseboard the color of the baseboard in the bathroom. 
No dust bunnies, and a much more streamlined look. I like drawers in my vanities.
I love the changes to the kitchen design and the cooking bay! The vanity is lovely, I would agree about losing the legs and losing the dust bunnies. The color is almost neutral, a grayish seaglass color. I wouldn’t worry about it being too colorful.
We have two bathrooms painted a sea glass color - “break time” by Shermin Williams. I love it! Very peaceful and soothing.
Have you considered - eliminating the currently drawn powder room and incorporating it into the back of the pantry?
It would make the pantry much smaller but it looks like there is room in the laundry for storage of big paper type items.
I think it would give a much more spacious and gracious feel to the entry and dining areas.
Its not just dust bunnies. We have a vanity with short legs in the our boys bathroom. All kinds of stuff can end up under there…
My kitchen island has two levels - the lower level has the cooktop, the upper level is so you can eat comfortably at the island with a bar stool.
The height difference is only about 4 or 5 inches, but it’s enough to install outlets on the vertical surface between the two levels. Perhaps that’s an option here.
They have pop-up outlets for islands.
Add me to the people who hate cabinets on legs. Who wants to lie down on the bathroom floor and wipe up all the cobwebs that will form back there?
Noo to dustbunnies! .
The cabinet in one of our bathrooms is slightly off the floor (very short legs) because the heating vent is down there (dumb design, but it is what it is) and stuff does collect under there. I am also not a fan of the open under cabinets in bathrooms. I prefer practical. Give me closed storage to hide band-aids and toilet paper!
Oh, wait, I almost forgot. My master bath cabinets are actually on feet, but there is a front trim over them that snaps on/off so they look like they go to the ground and completely built in, but I can snap off a piece of the trim if I want to take it to the store to find matching towels, etc. Handy dandy!
If it’s going to be on legs, they better be high enough to get the vacuum under.
Wow… lots of angst over the dust bunnies under the bathroom cabinet. Cabinets on legs are very stylish right now, but I agree that it is not practical.
French Drains - pouring money down them
Once again, spending thousands and thousands of dollars on things that no one will ever see or appreciate during an Open House.
Landscape crew is digging huge trenches all over the yard for French drains that will direct all the water out of the front yard and away from every single wall of the house. These drains will be hooked to gutter down spouts to make sure that no runoff gets anywhere near the house or foundation, just to be safe and make the house last as long as possible.
And, we are meticulously moving the large opening in dining room 2 ft to the left to capture more view to the SW. The slider will be closed up for a long set of casement windows along the dining room. Slider is not necessary any more because the whole deck is getting moved further south
cb, the French drain may not be something that gets ooos and ahhhhs, but the buyers will appreciate it in years to come.
French drains were probably the best upgrade we made to our house. You don’t see them but they make a huge difference when it rains here.
Ditto! French drains make happy downhill neighbors. 
Got a little spamail from one of the neighborhood realtors. Some of these bathrooms are drool-worthy!

The sea glass vanity is very pretty but seems to say “beach cottage” instead of “French country home”. Also, although the text says eight drawers, I’m pretty sure that the bottom two on each side are actually one deep drawer. At least every picture with the drawer pulled out shows it as one! Just an FYI; it’s hard to find eight actual drawers in a 48" vanity.
Would you consider something like this, or is it too elaborate? http://www.lowes.com/pd_432301-45065-HYP-0154-T-UIC-48_1z0vez1Z1z0vfevZ1z0vgdmZ1z0vgezZ1z0xzqlZ2zgig__?productId=50355394&pl=1#img Eight true drawers!
If you’re keeping the hall shelving white, this might work, especially considering the arch in the hall niche: http://www.overstock.com/Home-Garden/Naples-48-inch-Single-Vanity-in-White-with-Carrera-White-Marble-Top-Mirrorless/10298781/product.html?refccid=QAHO4MNMFQZ3IV2NABL6PDQHCI&searchidx=2
Some other vanities I ran across:

https://www.qualitybath.com/avanity-brentwood-vs49-nw-brentwood-vanity-combo-49-w-x-22-d-x-35-h-product-203797.htm Expensive but dramatic.
The house survived 70 years without French drains, why is it so important to put them in now?
I really like the one in the last link!
I agree with Marilyn above about the bathroom vanity, substantial and white or darker wood and lots of marble!
