"master" bathroom

Our master bathroom leaves a little bit to be desired. I know what sells a house and that's a great kitchen and master bathroom. We're lucky we have one that is attached to our bedroom so that's a plus, however, it's not the best set up. It has a little area for the sink/vanities and then a separate SMALL area for the shower/tub and toilet area. Then within that area there's an empty unused weird space! 

and not to be specific but when you sit on the toilet the door will hit your knees (not that you should be opening and closing the door when you are on the toilet but it happens?)

We've talked BIG and SMALL things we could do. Like I've said before, we don't want to over do it for the neighborhood, but then I think about what if we can't sell it in the end. OR what if we end up having to lower the price more than we want because we didn't upgrade the bathroom. Meaning if we spend the money now at least we could enjoy the upgrade instead of just spending money in the end to get out of the house withOUT the upgrade. See what I mean?

We have a hallway closet on the other side of that empty wall that James has wanted to push through since we bought the house. My problem is that our area/bath tub area is pretty small and not mastery and then you have that blah space. We actually put our big laundry hamper in the empty space to fill it (I took it out for picture).

I'd love to put a different style tub or make a different shower area but in reality we'll probably just get a longer white shower curtain and call it a day? 

What would you do with the empty space to make it look more "mastery"? What are your thoughts with a big type reno? It's also VERY hard to get any pictures of the whole area due to its awkwardness.

Another angle

Now, the real reason we are doing a little bit of renovating.... We have carpet in the sink/vanity area! When we replaced the carpet in our bedroom/closet we told them to leave this because we would be doing something with it that did NOT involve carpet. So Labor day weekend we will be taking care of it. We were just going to tile it and match it to what is in the toilet/tub area except there is not one tile leftover anywhere. So we'd have to eye ball it, bring it home to see if it would match, then buy some. I said I would be willing to do that, but James is being weird about it. He says he'd rather pull up all that new tile (at least it seems new) from that area in the tub/toilet and get a whole new tile for that whole area.

I think that's a lot of wasted energy to pull up perfectly good tile, but he's worried about the matching. I said well if you're going to pull up all that tile we might as well do a WHOLE BIG master reno (which is how we got to talking about the complete overhaul of the tub/toilet area). I also thought of doing a cork tile (I heard that's in? but is it as valued as regular tile? not sure....) or staining concrete?

So what do you guys think?! 

Just get a new tile that closely matches the tub/toilet tile and call it a day?

Go CRAAAAZZZY and knock through that wall and build a great big shower area?!

Anything to jazz up the area without knocking through walls?

Go big or go home?! haha
