In the picture, black is the current layout. Green is the change if only shower was made bigger and one door would be eliminated. Red is a complet demo, removing the wall section between two toilets. All the water lines from upstairs are in the section of the wall that is between two toilets so removing this wall would require a major move of water lines to the side and there would have to be a section of wall kept behind new toilet and vanity. The door from master would have to be framed and move to the left as a pocket or barn door. The drowing is disproportionate. It is all very cramped in there Current shower is only 26"x26". But may be replacing vanity for a wall hung vanity in the larger bathroom would change the feel. It will all have to be torn down and replaced including removing subfloors as they are rotten. So either remodel will be a lot of work. What should we do?

The "regular" bath layout that jensbride posted first is very similar to what our DD & DS shared for years and worked very well. The door, however, was a pocket style and placed directly across from the toilet. This allowed the vanity to be scooted around the corner to take up the whole wall. It leaves the toilet close to the tub, but with lots of elbow room. Our kids just learned to keep the door partially closed when the bath wasn't in use due to the "view".

I had Coretec (Dakota Walnut), terrible product. Impossible to keep clean, showed footprints, water dripping, smudges. NEVER looked clean. I always used Bona as recommended by US Floors..Back to square one, looking for a new floor. Considering Adura Max Apex.

See how the third picture that Beverly shows has the ceiling pot lights, in addition to the chandelier? All that supplemental lighting may be masking the shadows/bright spots that chandeliers sometimes cause. Be careful choosing the center light if you do not have supplemental lighting at the vanity so that you have even, not splotchy, lighting. If you do have lights at the vanity, it is much less of an issue, but if the bathroom is truly small, it may not have more lights. That is my only concern with crystal and cut glass light fixtures.
