Nice job! Being on the last leg of the reno of the 3rd (and last) bathroom in my house, I can appreciate that sometimes there are things that do not get the attention they should have initially. Like not noticing that the old toilet was centered 16 in from the wall and to remedy that the sick had to move which meant that the door wouldn't close etc etc etc. However, having looked at your pics and consulted with my project manager, we thought that you could look for something to put where you have the little freebee. It could be a one piece unit or a base either cupboard or drawers and a top that matched style wise. You could even place the little one you have on top, with or without the legs. Paint it whatever colour suits you. You could even hang the little one over the toilet tank ( too crowded for me ) or on the adjacent wall , if it didn't interfere with the toilet. In any event, I think the space between the windows is perfect as long as its clean , neat and eyepleasing as I infere from the pics that that is the first thing you are going to see when you enter. IT's amazing what a non-descript bureau or cupboard can look like with a couple of coats of melamine paint ! The Boss offered the suggestion that if you need storage for hair products, portable hair dryer etc, after years of struggling with cupboard storage, mess, things falling over, etc, she finally started using a large basket that she keeps in the closet in the adjoining room ( sometimes ) . Everything is close to hand, easily portable and actually doesn't look bad if left out . Good luck with the rest of the transformation

Thanks for answers. I am trying to locate a fabricator. My cabinet maker said he knew of some, but couldn't recommend them(!). I'm still waiting for the recommendation from my contractor. I wanted to use a brand called "Vadara", and they recommend I use one of their people. I suppose it might not matter too much which one I pick if it is warranteed.

I agree with Cpartist"s layout and like moving the closet over as suggested by D M so that bedroom 3 has easier access to the bathroom. Do you have room to have the toilet face the tub and add a linen cabinet next to the toilet? How wide is the tub toilet area?

After doing some research... what about using Ditra over the oldest tile after filling/leveling any cracks with thinset mortor? We plan to use small porcelain pennytile. The Ditra is 1/8" and says it "uncouples' the surface from the substrate. https://www.homedepot.com/p/Schluter-Systems-Ditra-54-sq-ft-3-ft-3-in-x-16-ft-5-in-x-1-8-in-Thick-Uncoupling-Membrane-DITRA5M/100143471 UPDATE— nevermind about this. pennytile doesn't work on Ditra. not enough support for tiny tiles. "Don't do it. I've seen hexes set over Ditra, with the flat trowel the day before method. The result? Lots of busted grout joints, and hollow sounding tiles. Seen the same with 1x1 and 2x2's also." Middle of the night research doesn't pan out. This is going to be much harder than the powder room unfortunately. We demo'd that room down to the studs but the substrate was just plywood. 😣😩
