Sorry if I'm late to the party here, but I liked your first option #2 for the reason that I like the closet area more separate from the bath and from a heating point of view, it's always better to have the rad on an outside wall. I like some of the changes you've made to the bath design in the latest options 1 & 2. I don't like the doorway in the hallway, and I don't like the bed on the window wall...I like to see light and what's happening outside when I wake up, not an interior wall. I also think its warmer to have the bed on an interior wall. I would suggest moving the bed back to the interior wall, and changing the door to a pocket door so you can center the bed on that wall opposite the center of the windows. This will give you a better look, better space to walk around the bed to the bath, and something to look at when you wake up.

I Like the initial plan (toilet at the window area) and with the wider layout. 43.3" = 1.1meters. If one was in a wheel chair they would not be getting into the tub so the tub is a moot point. The toilet room will be the same either way, if at one end or the other. Both will be plenty wide and deep it appears to me, for transferring to a toilet, with someones help or alone. You will need to know the specs if this is an issue you want to accommodate. Either way make the openings 36" to shower and toilet if you can. If you are still concerned about the distance from tub to vanity you could have your vanity made at 18" deep and gain even 3 more inches in the "hallway". Myself, I don't see the hallway as a limiting factor for accessibility at 43.3". Other things to consider is that the window may have to be tempered glass per code, if it is at the tub. Will you have a curbless shower? Will you have a shower door? I am going to get french doors on my 60" alcove shower so both can swing open and the full 60" is accessible. Plus, I like french doors :)

Mydreamhome- thanks for your thoughts...didn't want it to feel so closed in so that is why the 1/2wall, and the privacy wont be an issue for us. virgilcarter- I posted this question b/c I am concerned about the corridor feel. With the windows, I am hoping it will still be bright and open feeling. I like the idea of bumping out tub...just not sure what that might do to our budget, I'll have to check with our GC. Do you think separating the vanities to either side of the doorway would help? DH always just waits for me to be done so we are never really in each other's way. dekeoboe- the window is centered on front of house so we can't change it...that would have solved my problem!! Thank you all so much for the feedback!!

I agree with Cpartist"s layout and like moving the closet over as suggested by D M so that bedroom 3 has easier access to the bathroom. Do you have room to have the toilet face the tub and add a linen cabinet next to the toilet? How wide is the tub toilet area?
