Grab some graph paper and a measuring tape to create the existing floor plan with location of doors, windows, closets and bath fixtures. Let these pros know your budget and if you plan to remove walls.

Valinta is absolutely correct - you need to grab a tape measure - and some graph paper (my understanding is that you can actually print some off if you do a search online).

While you've added some photos + described what you'd like to do (incorporate hallway into bathroom) - it's difficult for someone unfamilar with your actual space to be able to visualize everything. It may seem like a pain to take all of the measurements + create a scaled drawing - however, it's crucial IF you want to receive the best advice/suggestions.

The pros (+ non-designated pros) are able to come up with layouts that function well + look nice. You will most likely receive a couple viable options that you can choose from in order to decide on a final layout for your project.

It is important to let people know if there are any special considerations (e.g., if someone has limitations re: mobility) + a list of "must haves" (e.g., some people require a WC for the toilet in their primary bathroom - while others might not care - or even actually prefer to not have a separate WC) and a "wish list" (items you would like if possible).

Also. list any walls that cannot be moved + if you don't want to move plumbing/sewer lines, etc.

This looks like it will be a significant project - so, the time and effort put into creating a scaled drawing (including all windows/doorways + corresponding measurements) are definitely worth it!

Are you saying you don't need that closet space - you want to incorporate the space in the closets into the remodeled bathroom, thus eliminating the closets?

That is a lot of work to just gai floor space in the bathroom unless you are going to reconfigure everything or get rid of the closets and make a huge bathroom. Also, many designers will tell you to not have clothes closets in a bathroom ( humidity ) and in this situation I would have to agree.

Post your floor plan and the bedroom as well and see what everyone can come up with

We need that to scale plan no way to help without it.

If that wall isn't load-bearing utilizing that space sounds like a good idea, wish we had some extra space lying around to expand our MB! We have our closet attached to bathroom without any issues but we don't have humidity problems.

With the new toilet placement it would odd to have the far closet as it would have to be accessed while practically standing on the toilet and it would be the first thing you see from the door which isn't ideal IMO. A better layout could be made but would involve more plumbing changes than just moving the toilet. Is that doable?
