Master bathroom: Eliminate the window in the shower from the plan. Enlarge the master vanity to have two sinks and more drawer storage. I assume that what looks like two toilets is actually one toilet plus one bidet. You need the two closets! Once you decide what to wear, bring the pieces into the bedroom and get dressed there where you have plenty of space. Put a chair against the wall to the right of the closet area and two hooks on the wall to hang your items before dressing.

Im going to need a picture.

Framed mirrors are very popular these days. Depending on your faucets, you may even find trim that perfectly matches the faucet finish. Moen faucets have matching trim (and matching towel bars, tp holders, etc.).

What is below the bathroom and closets will be a consideration when remodeling. You will have to connect water lines and waste lines to the existing system within the house. You may uncover asbestos and outdated knob-and- tube wiring. Once exposed, these must be replaced to meet code. On the other hand, two small but functional bathrooms is better than one outdated big one. Those closets are too small for current needs, so losing them is not important. You don't give the measurements of the two bedrooms, but compared to the bathroom, they may have enough space for new closets. You should call in a contractor or two to discuss possibilities and to give you ideas for upstairs and how it will effect the area below, and to give you an estimate for the job. Of course you will do everything with plans, permits and inspections. If making two bathrooms out of one is too pricey, consider rearranging the whole space and turning it a more functional shared bathroom: two separate toilet-and-sink half-baths with a shared shower/tub room between them. It still would require reworking all water and waste lines and electricity, but might be slightly less expensive.
