What you describing is not going to be economically, it will be a total bathroom remodeling with plumbing re-routing etc if you planing to move the toilet, etc.

Have your contractor determine if moving the plumbing is an option. Is the bathtub/shower plumbing on the same wall as the toilet?
If you have the room for a 60" vanity with two sinks it is helpful for personal and resale.
I am remodeling a 4' x 10' 'master' bathroom and had to settle for a 54" vanity with one sink. Guess who gets to use the guest bath?

Yes, the shower plumbing is on the same wall as the toilet, and when I said economically I just meant this isn't an extravagant project. I will be doing most of it myself, probably hire out the shower part. I just wasn't sure especially for resale purposes, if that toilet placement was going to be a huge issue for buyers

I prefer two sinks.

If two people will be grooming at the same time, two sinks are necessary, and for a master bathroom, I always prefer two sinks. A long vanity with drawers for each user’s small implements and some under-sink storage is important. A long single mirror will help the room look bigger. Moving plumbing is an expensive choice, so get a couple of estimates before you decide.

I would want to move the toilet. You could increase your vanity to 7 feet!

Random thoughts:

- Will you send us a floorplan with dimensions?

- Moving a toilet is one of the most expensive things you can do in a bathroom.

- Is the bathroom on the first or second floor? If first floor, do you have a crawl space or a slab? Big price difference.

- The toilet and shower's water sources are on one wall ... and the vanity is on another? That's weird ... and more expensive than just having put all the water in one wall in the first place. Can you see any reason why it was done that way? What's on the other side of this bathroom?

- You say you're doing this on a budget ... will you go with a shower insert or an all-tile shower? Moderate price difference.

- Is the vanity curved, or is it a trick of the photograph?

- Is that a pocket door into the bathroom? This may be a hint as to the location of the plumbing ... a pocket door requires a thicker wall ... walls that contain water must be thicker too.

- Yes, we usually see all the "water items" lined up on one wall ... it's an economical choice, and it allows for a good walking aisle. It just works.

- I think your toilet looks out of place because of the blank space on the wall between the vanity and the shower. I think I'd leave the toilet exactly where it is (budget) ... and add a more shallow vanity or set of shelves in this "empty spot". It'd add storage and make things appear more balanced.

- If the vanity is in good condition, consider painting /reusing it. Vanities are not cheap.

The layout of this entire house is weird and makes no sense!

-its just the photo. Not curved vanity

-the kitchen and a powder room are on the other side of the wall for the vanity wall

-first floor with encapsulated crawl space

-standard door not pocket

-planning a tile shower not fiberglass again

maybe that’s why it seems so odd, that blank space does make it seem unbalanced.
