It doesn't matter! Choose whichever looks most pleasing to you. Put that big box at 9" height, then walk out/in. Repeat with the 11" height. Which looked better? That is the one you pick.

I think the 9" height looks fine. Also, I would much rather have more storage space than space for dust bunnies and dropped items to accumulate.

I am taking the cabinet builder's side.

This one has a floating shelf. I think it looks good, but I imagine a lot of dust bunnies find refuge under it. Nine inches give you enough clearance for cleaning and room for storage. I think nine inches is fine. Look at some floating vanities on Houzz to get other perspectives. I think many are more than 9 inches. But not all.

This one has a floating shelf that looks really close to the floor. I bet a lot of dust bunnies find refuge there.

You've been remodeling for like 5 years! How did your doors turn out?

Anyway, my vote is 11".

ETA: reason being, I like to see the floor underneath. For me thats the whole point so if I cant see wall to wall tile it could be just a regular vanity then.

Low enough to clear the plumbing drain trap... you did plan this while consulting with the plumber right? lol.

@JJ Yeah, it's been a long, slow journey. Refresh my memory on what doors you're referring to? There were probably a couple of door related threads.

I ended up going with 11" inches from the ground because I think it looks better. I have a designer that I bounce questions off of sometimes and she prefers 11" too. I don't really lose much storage space. Those 2" are divided between three drawers which is negligible. And there are open cabinets in the vanity where the 2" height definitely won't be missed because I've never piled things up so high it touches the bottom of the sink.

I appreciate the feedback from everyon!

2" is a distinction without a difference in this situation...

Ours are 11" above, but I wouldn't want to sacrifice storage. I think it also depends on what the unit will really look like, proportion of vanity to sink, ie can you do a thinner countertop/sink and have more storage? Or atthe end of the day, how much storage will you really need and will it all fit if you have 2 " less?

I think I saw a yellow penalty flag thrown on one of yesterday's comments.

How about 10"?

I was wondering how you were doing, long haul from the red tile. I think my floating vanity is about 10” off the floor, but i am short.

As long as Roomba and Swiffer fit under, it's all good.

Now I have decided to make my vanity 11" off the ground.

Does anyone have photo's of their floating vanities? Uscpyscho, could you post a photo your finished vanity 11" from the ground vanity? Thanks in advance.

Our builder has our floating vanities mounted such that the top of the sink was at counter height. We have 5 baths with floating vanities and they are all mounted at different heights.

Hi Kim, thanks for the input. Sorry, this may seem like a silly question but are all of your vanities different sizes? How did the builder get each of the 5 bathroom sinks to be at counter height yet have them all mounted at different level unless the measurement of each vanity is different?

Our current "floating" vanities are 4" off the floor. (Gravity weighed them down over the years.)

Like pedestal sinks, floating vanities put form over function.

@pinkysonpatki6 - I have two heights of vanities. One was custom made by my father and it is shorter - its a box mounted on the wall. Its for a half bath. My other vanities are all the same height but mounted at different heights so the tops of the sinks are at counter height. All of my vanity sinks are different heights. Anywhere from a tall vessel to medium to low height ”drop in” to a regular ”drop in”. If all of my sinks were the same then each cabinet would have been mounted with the top at the same height on the wall. You don’t want a tall vessel mounted on a counter height cabinet as it very cumbersome to wash your hands, brush your teeth etc unless you are tall and I am not. I just measured the height of the top of the sinks in two of my baths downstairs and the top of the sinks are 37” above the floor. - a little more than counter height.

If I had to pick a number it would be 9 inches minimum.
