We need a to scale rloor plan of that whole area also good to post the bedroom this is joined to. Is it possible to move plumbing like the toilet for instance? If at all possible I would check out closing in that 20' ceiling it will save you a ton on heating and venting What is a stand up tub? I think toilet rooms are just silly, no one should be using that when someone else is in the bathroom. These make sense when done like in Europe where the toilet room is not inside the actual bathoom. A walkin closet will eat a lot of space and do you need that loft space ? If so is there another way to access it ? In the to scale plan show every window , doorway where those lead and every measurment clearly marked use graph paper to make it easier. Also include info as to walls that can be moved ones that contain electrical or heating . Mark those with a colored pencil. You post the drawing here in a comment in jpeg format. This post is where everything relating to this space is now dealt with in comments .I just checke and a stand up tub is a freestanding tub and that requires a very large space which will be iffy with all you want from this spac e.

That loft would be awesome for children if it could be accessed from somewhere else! It would be like an inside treehouse!

What a great ceiling! Please provide a scaled drawing of the bedroom/bath/closet - include dimensions for all walls/windows/doors/doorways/etc. People will be able to provide a lot of assistance if you are willing to put in a little effort to make the drawing (use either graph paper or a ruler - 1/4" = 1').

Please provide a dimensioned floor plan for the entire space for proper assistance.

are you gutting the space? Leaving the plumbing/water source in the existing locations?

Is this ground floor or second floor? Where is the bedroom?

Thanks everyone! I will work on a detailed drawing. We would gut the entire space. This loft is shy of 5 ft so it's hard to move around up there. We would be over to moving the plumbing. This is the ground floor. The bedroom is on the right side connected to the door entrance.

With that much space, I’d probably work out the shower, toilet and vanity locations first before worrying about the finishes. The toilet room and closet could make the layout feel a little tight depending on how much space they take up, so I’d leave enough clear space around the main bathroom area.

I also like the idea of separating the toilet a bit from the vanity/shower area. I’d sketch a couple of options with the door swings and actual fixture dimensions included before deciding. That usually makes it easier to see whether the layout really works once everything is in there.

Option 1 (keep all features with small tweaks): Ditch the fully enclosed toilet room for a partial glass toilet nook, freeing up 3–4 sq ft for the tub and closet. Only lower the ceiling over wet areas; keep the full 20ft vaulted ceiling above the closet to balance energy use and aesthetics. A freestanding tub set against the wall reduces required clearance. I don’t recommend converting the attic for living space — under 5ft tall, it only works for low storage and isn’t worth the added cost.

Option 2 (focus on better flow): Remove the soaking tub and expand the walk-in shower. This creates far more room for a bigger closet and easier movement.

If you want to keep the soaking tub, scaling down the toilet enclosure is the main tradeoff to look at.

Still waitng for the plan
