With the installation of the new vanity, now your sink will no longer be positioned, centered beneath the mirror/light combination. What a mess

I know it’s a terrible layout I think I’ll remove the lighting and add two matching pivot mirrors that way I’ll get some light from the window still mill have to add different lighting

Add a hinged mirror with shelves in the window but that would block the light completely

Are you planning for two sinks or one offset sink? Is there an interesting view from the window? Do you need the privacy of an obscure window? Can you make it a clear window with a pull-down shade?

I am attaching a photo that I took of a secondary bathroom in an open house in 2017. This was a very expensive custom-built home with many personal choices by the family for whom the home was built. Notice that there is no mirror above the offset sink.

I think that your space can work "as is" if you are willing to make some unconventional choices. If you have space for a separate make-up countertop, then no mirror is needed above the sink(s), and the countertops can be lighted with recessed ceiling lights.

An alternative is to install matching wall-mounted LED lighted makeup / shaving mirrors on the sidewalls, with no mirrors in front of the sinks.

I am guessing that you do not want to change the window size / location. Otherwise, you would be able to do something like the Houzz inspiration photos that I am attaching. Move the window up higher and longer; center same size window over the vanity; enlarge the window to cover most of the wall in front of the vanity.

How about using two pivot mirrors; one over the window like this:

You could mount both mirrors on the sides - or just the one that is on the side with the window. Add an identical wall mounted mirror on the other side.

You could have a mirror that is mounted on the wall over the left sink + have an identical second mirror that is on a sliding tract that can be moved directly over the window when using and then moved back over so it "hides" the wall mounted mirror behind it.

Find two mirrors that match - mount one to wall and the other in front of the window:

There are many different ways that you can hang the mirror that goes in front of the window - below, the chains are very dainty and would be a nice way to hang your mirror over the window (wall mount a matching one on the left side). You also could set up a curtain rod and use it to hang a mirror by dainty chains that you can slide over the window when needed over the right sink.

You could use a single long sink and install it over towards the left side of the vanity + mount the widest mirror that fits over the sink (the below photo doesn't illustrate the idea - it just shows the type of sink that could be used).

People are using mirrors that are mounted from the ceiling even when there isn't a window - you could simply purchase two mirrors similar to below and mount one over each sink. It would block some of the light - but it would also allow light to filter in all around the mirror. There are many styles/sizes/shapes of these mirrors - they even sell them on Amazon.

You could also make a pocket mirror if it would work in the wall on the right side. The mirror would simply slide in and out of the wall just like a pocket door does. I don't have a photo of this - it's just something that I thought might work.

I'm not a designer, just giving my visual opinion. I would definitely remove the side mirror and the light fixture. I would put overhead can lights in ceiling. What about a full wall mirror with the window cut out? I do like the idea (dani_m08) of the mirror on tracks that can slide on either side of sink. Is there another window in the bath? If so, can you remove the window?

Sorry "LOSE" the window and just cover it up

Call the electrician, get two lights.

Get some recessed 4" in the ceiling. It was a big mistake in the making at the get go..

Two mirrors to INCLUDE frame at 30" x 42"-

Make sure you have a good fan in the bath and get over it. Plenty of baths have no window, just good ventilation and an open door on exit.

Will anything else look good? NO.

Could you have matching mirrors centered on the sinks with the right hand one being on a hinge so you can open it and enjoy the window when you want?

^^Yes you can do that...

Have the mirrors made at a local FRAME SHOP. They will also tell you exact glass to purchase, ( any local auto glass shop/ 3/8" thick ) to fit the molding frame you have chosen, and will hand you back a nice framed mirror.

Put hinges on the one over the window

same thing as Below.

@JAN MOYER - I thought that losing the mirror was the best idea re: how it would look. However, the OP mentioned an issue re: blocking the light - so, I assumed that it wasn't an option.

@Nooshin G - Jan is a well respected designer - her suggestion is from an expert. I'm an attorney - so, my ideas were just trying to think outside of the box.

Light.......especially in the evening is an electricity factor!

I've had a bath with no window for all of my adult years. No problem, no mold, no lack of vision, no issue.

Light it up!!! electrically. The more mirror over the vanity, the more light and sparkle.

We had a similar issue arrise during our remodel where the plans of one bath got mixed up. When I noticed it (I should have had it fixed then) but instead we walled up the window and hung a large mirror on the new wall.

Our window is larger and covers more of the counter space and I have been considering removing the mirror and wall and hanging mirrors in front of it.

But prob won't go to the trouble lol
