No tub? If not, then there are lots of things you can do. Do you have a sketch that shows where the doors and windows are located?

are you replacing the tub tile at all? or just the scroll piece? another idea is to take the same quartz countertop and have the top portion of your tub surround done in the same. that way both vanities and top of tub all match. doing a solid color would work better here since you'll want to coordinate w/the tile floor. If you did that, take the tile off the wall above the tub and you could do something like this If keeping that tile on the top of tub, then it might be an issue. you may just want to keep the scroll piece under the window. that's up to you. all depends how far you want to go. if you remove the scroll, you could do a little wood shelf across, below the window, for plants or orchids. as for the mirrors w/the lights in them, they're all over. just google 'vanity mirrors w/lights', or vanity mirrors w/medicine cab" . they are a bit pricey though. 600 and up for the very nice ones. Robern medicine cabinets are a well known name. if you want a taller medicine cab on the side, you will have to have the recessed portion of the wall made taller. as for the tiling portion, yes, just the front wall,,,you would paint on the side portion. I really like this look for your room. you don't have to do MOP tile, it was just a suggestion. there are tons of beautiful tiles you could use. If you did more of an ivory or subtle countertop that plays well w/your tile floor, then you could have more options to play w/some tile. The sconces pictured here are also nice, but there are many other types you could use as well. Don't want to bother w/sconces? then ditch your mirror and buy a backlit, or complete edge lit mirror like this one. you could still do your tiling like shown here. These are also very flattering. this countertop is limestone, below, and is more of a neutral, greige color. i would keep your ceiling dark, like you have it,,maybe do the walls a lighter shade...all depends what you pick for the vanity and tile. Having the mirror cut down isn't expensive. hopefully they can get it off the wall w/o breaking it. doing the tile around the mirror defines that area and gives it so much more appeal.

My opinion will be biased because I have very similar tile in my master we redid 12 years ago. 4" squares on the diagonal for the shower floor and 12" squares on main floor and up the shower walls. Coincidentally we are in process of redoing my kids' bath the past few weeks (it was also redone 12 years ago) because a hard-to-find leak in the tub prompted us to consider replacing it....which then brought about the issue of replacing the tiled tub-surround that would be damaged...and we would also have to try to retile some spots on the floor because a new tub would be a smaller footprint leaving some bare spots once old tub was pulled out. My point is that we also had to figure out the whole, "do we do an updated 'patch job' to save a lot of money, or do we just gut it and accept the cost as the price of being at peace with it/enjoying a new look and improved function. Right or wrong...which is always a very subjective thing....we gutted it and I'm thrilled. I was not interested in painting my cabinets just to have them have peel-issues due to steam, and we also got rid of the tub altogether and opted for a stand-up/walk-in shower for my older kids. Resale was considered on this issue...but by the time we move, someone can either love it as we've made it, or we will price the house with an "allowance" in mind. The old space had hot-chocolate colored walls and 'slate' porcelain floor and tub surround...an overall warm and cozy feel but also tired and dated. The new space is a porcelain 'marble' hex with white subway walk-in shower that is awaiting glass doors...an overall calming feeling that is also bright and fresh. I now actually wish SO BADLY that I was able to redo/retile MY whole bathroom (tile similar to yours). And there's nothing wrong with my bathroom, and a planned paint job on the walls will help me like it even more...... In my kids' bathroom, however, even unfinished with the floor and shower tile installed just waiting for the rest to come together (waiting on backordered tile base moulding) ......... I walk in and just smile and breathe deeply because of the way the space now makes me feel :) So my very biased vote is to gut it ;) ;)

Changing the horrific floor isn't an option right now we aren't really rebuilding  upstairs just replacing things that we're broke n covered under insurance. This wasn't planned  but once in house ill do floor just have so many other things to take care of first I wish they could rip it out n I had more time & we were doing this bc we chose to so I could properly plan out things & get what I like but for now I'm just grateful to get back in ! N ps I plan on doing a wallpaper too but for now " Agreeable gray " it is. ! I would of gone w white but  at the time I didn't know what I was really going for ? My house was a mess & my husband was seriously burned so my thoughts were elsewhere. Thank you for all the  helpful input I truly appreciate it
