Something like this may work. Note the changed door positions so that anyone in the bedrooms can visit the bathroom without disturbing anyone else in the lounge !

standard bathtubs take up space, look outdated and in today's busy life, rarely do we get time to use them. Better go for a high end steam shower with a bench seating if its within your budget. However, a free bathtub in a large bathroom however can be staggering. From my experience and the skill set available in our country better not attempt self made, it is quite demanding.

Hello Sagar, This space is sufficient for a bathtub in a bath. Thanks, Nitin CORNERSTONE DESIGNS, Bangalore

Hello there, There is a whole bunch of materials that could be used as a partition. Basically anything waterproof could be used as partition. What really matters in a small bathroom is the thickness. You could put a laquered glass fized partition available in a variety of colors. Regards, Aurum Ideas and Spaces Bhubaneswar
