IMO best to gut and start over by the time you fiddle around trying to do what you want it will have t be demoed mostly anywhay and to work with your bedroom it all needs to go including the tub which BTW is probably harboring all kinds of gross mold in the pipes. A nice clean lined soaker tub if you need one . If you don’t use the tub in the master bathroom and you have at least a tub somehwere else in the house just do a nice big shower. Since the bedroom looks very contemporary I would use high gloss white Godmorgom from Ikea for vanity and storage in the bathroom with a black granite counter . If you ost a to scale plan here you will get lots of ideas one question you will be asked is are yo on a slab or do you have access to the plumbing without chopping into the slab.

Thank you very much for your reply! We have 3 full bathrooms and this is the only one with a tub. It was not used much, so looks like new! I like the idea of freestanding tub though! Godmorgom with a single sink comes only as 48 inch I think, but I guess I could buy some additional storage cabinets. Sorry for my ignorance but not sure what you mean by the slab! The entire wall where the shower is, will be demolished so some plumbing and electricity will be moved to a different wall! My husband wants a Tv in front of the tub...it will be on a wall beside the mirrors! There should be more room once the shower walls are gone
