You want to pull the vanity all the way to the left? Here is what we did when remodeling a small guest bath in our Florida home. It came with a vanity wall to wall. We replaced with a smaller vanity with a left offset sink. Now there is room on the right to hind the toilet bowl stand, room on the left for trash can. That bottom drawer holds so many hand towels. The drawers make more sense too than just doors. It appears you have a similar problem having in front of the toilet to wash hands.

Solid surface materials are always popular if you do not want grout lines. Tile is always an option also. Do you have any kitchen and bath stores near you to go look ?

What are you looking to change exactly? What can be moved and what cannot in the way of walls and plumbing? Is the shower behind that fireplace wall? Can you post a floor plan with dimensions? Graph paper and hand drawn to scale is fine. Inspiration pics?

Help with what? What do you need in this bathroom? What size is the bathroom? What size door? What size window? We need a floor plan with every dimension included? What can move, plumbing, electric, etc.?
