If the choice is small-small-small vs. large-large-none, I'd go with the latter. I did see a couple higher-end parade homes this year without tubs in the master, so that means you're not alone in seeing them as unnecessary. It might eliminate a few buyers from your list (I'd be one of them), but hopefully that would be offset by the attraction to the size of your shower and closet. You need to balance resale with the functionality you need. And you obviously value a large closet, so you should go that way so you'll be happy in your home.

Our budget right now is $30k. I am not quite sure how much that’ll get me. I have never undertaken anything like this. This will absolutely be something we take on in stages. This space is what we’d like to tackle first and is the largest. In our kitchen at some point we will replace countertops and in our other bathroom we will swap out the toilet, tub and vanity. Luckily the rest of the house is functional for us. I lack the vision and knowledge that a lot of people on here have of being able to see a functional layout in disaster zones lol. My intuition tells me all these spaces can somehow be rearranged to give us what we need. I’m completely wrong, please help. Im also completely fine and understand if it’s impossible, financially or practically to have it all. I do have a consultation with a designer scheduled for this week (so excited), and I’m praying that she’ll have time to take us on as clients but I got excited and wanted to ask the Houzz community first. Thank you !!

My first collection of comments are related to your revised drawing/plan: As I look at your revised drawing it doesn't look square. You state that the room is 6x6. But even so I think you will only get about 19-20" between vanity and toilet. Unless you got an 18" vanity, which is what I did in my East Bathroom that is 6.5' wide. If you remove the chimney you could put a window there. I've placed a small window in my West Bathroom, that previously was lacking one, and I love it. In my West Bathroom (I show in the last set of pics) I have a cast iron Kohler shower pan that is 36x60", with glass doors (French). I could see you doing something like that in your room. The curb is about 2" finished floor. Easy to get in and out of. The cast iron is a dream to maintain. Even better might be using a 36x48" pan then have 18" to one side for storage, as you can see in East Bathroom pictures, to the left of the tub. The storage could be in the form of pullouts like a pantry, or cabinets with pullouts like mine. They would be deep, so the pullouts would be very helpful for access. If you did cabinets, the lower drawers wouldn't be as deep, to allow for the toilet. The upper ones could be deeper. The plumbing could be housed in that pocket too. I like the idea of moving that closet wall to give you the width you need for the toilet and vanity. My East Bathroom; to demonstrate 6.5' wide room with 27" toilet round bowl, with 18" vanity. The floor tiles are 6x12 to help with floor scale. The pull outs at the tub are not as deep as the 30" tub, due to the toilet in the way, but are great for storage. roughing in: the pullouts, the plumbing is in there too and you can just sort of see the wall mounted tub fixtures. the pullouts come out as far as that door, just to the toilet tank: This toilet is the Toto Promenade in the round bowl. I love this toilet and would recommend it. But I love Nancy's idea of the wall mounted toilet with the tank in the wall. I have a Bidet on it now as you can just slightly see by the toilet lid in the pic above): These second comments relate to the plan where the chimney stays in place: I like the idea of expanding the shower. Here, a Kohler pan 36x48" could work well. One thing I did in my West Bathroom was a long wall niche that allows for a bit more elbow room. Its the only thing I like about having a niche, because they can get bogged down with products and trap water on the shelf, causing mold. I wipe down my shower daily following the showers. Last one to shower gets the honors. Its a quick wipe down of all walls and glass. Floor gets a clean every couple months, if that, depending on the shower load. I haven't had to "clean" my shower in 4 years, because of my daily habit (that I never had before). So glad I adopted this habit, I did not want the ugly mess that my old acrylic shower/tub combo had become. Since your wall is not an out side wall you could put a niche there. I only place 2 bottles of product on that shelf, lol. Any extra go in a basket that sits on the shower floor at the far end. I have a nice clinical shower stool in there too, with a gray seat that matches the floor. Nice to sit once in a while to let the rain shower head run on me. Having your toilet move down into the new expansion would be great. If you could move the wall 18" you could have that left wall become a wall with shallow built in 15" cabinets. Maybe a even a pass through into the closet for some things. It could even have a counter and uppers sort of like a kitchen. My West Bathroom; 5' shower space, with grab bar, niche, Hansgrohe rain shower head and hand held, and Fantech brand exhaust fan with light on the ceiling. The motor is in the attic and split into two locations in the bathroom, on at the shower and the other at the toilet: French doors, allow me to open the whole thing if needed, but I just use one normally: Kohler shower pan, in remodel process. This one has a center drain: Don't forget the exhaust fan, and a gap under your door to allow for make-up air to enter the room so the fan can work at evaluating the moist shower air.

We redid our master bath not long ago, and I struggled with one long/two shorter mirror options. I found this process helpful: Assuming your big mirror is still in place - use painter's tape on the mirror to mark two outlines the size of the individual mirrors you might want above each sink. Cover the middle section between the outlines with a roll of kraft paper or butcher paper (or even the back side of a gift wrap roll) to simulate a blank wall in between them. If you have a long "Hollywood" bar light across the top of the whole thing, unscrew the bulbs in the center to simulate having two smaller fixtures over the mirrors. ( To be even more realistic, mock up a tower in the center to see what impact that has. You could stack up narrow boxes, or buy a $15 sheet of Styro insulation and fabricate the approximate shape.) Evaluate what you see in the outlined areas that represent two smaller mirrors. You may still see the shower and toilet as very close. You may find that you don't like the loss of reflected light in the middle, or that the tower casts shadows. Or maybe you'll like what you see and it will reassure you that change will be good! In our case, we stayed with the long mirror. We preferred the additional light, and found it more appealing in our space to use three new lights over one mirror over two sinks, rather than the rigid symmetry of two sinks/two mirrors/two lights. Good luck!
