Are there any other bathrooms in the house?

Yes on the first floor- but would be quite keen to keep a bathroom up there if possible as a master bath

So you can change the exteriors walls or you want the same one if not than we can change ur bedroom no-5 in to the mstaer bathroom with walk in wardrobe and with walk in dresser with big windows (in the arch area).
In ur bedroom i think we can change the direction of ur bed as well as put divan ahead of ur bed , tv unit near window.

I agree - we did a walk in ardobe in a similar sized room - I was trying to link to it - but it won’t let me ... so iff you click on my name or icon to get to my pro page it’s the projects that looks like this screenshot ! Hope it helps ...

Sorry for typos - it’s not my day today !! Can’t edit things !!
