Too small for it all. 58” is too small for a double vanity and double mirror. You have no storage, and it’s very busy and crowded looking.

If we do two recessed medicine cabinets of 15x30 or 20x30, we get the storage but will it still look cluttered?

IMO a 60” vanity is too small for 2 sinks.

You do not have room for two sinks. And that vanity is too small to take two mirrors. Just do one large mirror. And I would not do medicine cabinets. That is too dated a concept for me.

You have to think on the scale of a real-life homeowner, not a designer of high-end homes (unless this is a high-end home!). When things are tight, you look for solutions!

If 58" is too tight for two sinks, look at a trench sink - a long skinny sink with a faucet on either end that serves two people.

This is the concept, but like so much stuff on Houzz it is marginally useful because whoever posted it just slapped it up without dimensions. In this kind of a get-up, WHERE to center two medicine cabinets becomes the issue, so a single mirror wall does seem to look better.

In this example, designer Kelly Gardner does tell us all about her project, which seems only the right thing to do if a designer is getting advertising by posting it here for us to see! She says, "

The sink is 34" and the entire width of space is 48". The space between the faucets is roughly 22"

Now, doesn't this look like something you could do in your 58" space? Ask your contractor if it is too late for wall-mount faucets (it probably is). Your sink would have 5" more counter on each side. Come to think of it, this may be a shallow counter (maybe they had a space issue) and with a 22" deep counter you may have plenty of room for a faucet. Kelly says that this sink is from Lacava, so if you like this look, review their catalog online, then find a source to buy one.

My original bathroom plan was to get a Kohler Brockway sink. Funky, old fashioned and really splash-happy! The Brockway has a backsplash and the whole sink is 18" deep, so in a 22" counter, you can make a little shelf between the backsplash and the wall. The sink has a big round belly that begs to be pulled forward out of the cabinet, and if you do that, you can have a deeper shelf behind the splash. Here are couple of installations.

First, this is the smallest Brockway, the 3 ft (36"). It comes in 4ft with two faucets, too. Here, they mounted it against the wall in order to have a bit of counter in front of it, instead of pulling it forward and putting a shelf behind it. Also an excellent choice.
This is one of my favorite installations and it also gives you ideas of what you can do with mirrors and cabinets. It is a cottage look, though. This is the "belly exposed" look, where pulling the sink forward gives you room for a shelf behind it. I can't really see a shelf here, but you can see where it would go, where the sink top ends. Just make a shelf behind the sink that fills the space between the sink and the wall. If you have stuff on it, you cannot open the doors of the cabinets here, which is a good reason to leave it off, I suppose! This is the 4 ft model, which is too large for you, giving you only 5" on each side for counter. You should go with the 3 ft, giving you 11" on each side for counter.

Wetstyle, from Canada, has many trough sinks. Here are some that sit on top of the counter, just in case the cabinet you ordered cannot take a sunken one.

This the the Wetstyle Ove sink in the 48 x 15" size. It is only 4" deep, so you have to be careful to chose a faucet that will not splash the water out. But it gives you rounded corners, lots of space in front or back of it in a 22" deep counter, and you each get 5" on each side to have to set things down. What is even better about this picture is the mirror design. See it? A mirror is inset into the wall cavity, giving you a small ledge to set things on as you are getting ready. It looks like the side mirrors could be small med cabs, if they are not. What a smart design for your small space! Click on the photo to enlarge it and see the details.

Here is the Wetstyle Cube collection sink in the same dimension. It is just a rectangular version. Click on "more info" to get a version with the price tags, where you can click on the tag to get a close-up of the sink. Being only 15" front-to-back, there is lots of room for faucets behind it. If you do a shelf in front of a recessed mirror, you may get away with a 4 ft long sink - especially if it gives you space in front or back to set things down.

Check out Lacava, Nameeks, and Duravit and you will see many more sinks that sit on top of the counter that are long enough to have two faucets. There may also be some that are "semi-recessed," which means that there is some sink below the counter, too, giving more depth.

Rachit, you need to find out what the top of your vanity is like. There will be supporting wood struts going from the front to the back of the vanity in several places - making up the drawer compartments, framing the sink compartments, and such. If you want to consider a trench sink that goes below the counter, it has to go between these front-to-back wood struts. You may be limited to having a sink on top of the counter if you bought a cabinet designed for two sinks side-by-side.

You can still go with two sinks, if that is what you want. Since space is tight side-to-side, it might be better to look for sinks that are longer front-to- back than side-to-side. Doing a recessed mirror with a shelf in front of it to set things on as you are using them may make the squeezed-space feeling between two sinks in that size vanity feel better. Or do two skinny med cabs and then put little shelves between them like in the Brockway sink picture. It would be smart to put an electric outlet on the shelf for toothbrushes, too. Or get one or both of the cabinets with electric inside (which can get expensive, though).

There is the ideal "looks best and functions optimally" version of design, and then there is reality. You can push the envelope a little, in order to make some things fit. It is important to know when you have gone too far and need to stick closer to the rules in order to make things that will be usable. But tricks like making ledges behind tall sink backs or sinking the mirror into the wall and putting a ledge in front of it can get you there, too.

My problem with double sinks is when they are too close to the side walls. If I can't use one arm while standing at the sink, it is not a functional design.

Post a picture of your cabinet if you want to explore some more specific things that fit your cabinet.

Unfortunately I do not have a picture of the new vanity. I am inclined towards 15 x 30 or 20 x 30 in Kohler Verdera collection currently and then put two lighting on top. Real confusion is however what should be the size of the cabinet/mirror 15 wide or 20 wide?

You could get graph paper and draw it up and see which looks better to you. It is going to be a matter of taste.
