Dear Client,
I think there is a huge potential in moving bathroom entrance wall towards bathroom to create wider wardrobe and to "hide" entrance to the bathroom.
I left WC where it was placed because of plumbings and added bidet in there. On the opposite side now You have a great mirror with double sink that opens master bathroom.
At the end of bathroom there is wet area which is elevated on wooden planks which creates nice and warm atmospfere for shower and bath.
I hope You will like mine design,
I wish You all the best luck with Your Master bathroom renovation!
