Please don't forget you must have really good drains for this extra water load. Have you considered a tankless water heater? Or at least a separate water heater for the master so that the rest if the household still has a hot water supply and pressure balance. That's something to consider also. I've often wondered, I must admit, how all of this is supposed to work with energy saving measures in place.

Wow that's way too much. How would a polymer alcove come in from the main powder room door ? A comfortable moving space is around the 23-24 inches. It may be too cramped up imagining from what you have described. WC is facing towards the shower area? You may draw up the plan and share it here for better understanding. Nitin Cornerstone Designs.

Ankur, It is called by a few different names Nano Coating, Ceramic glass coating and hydrophobic coating. Depending on your location you can buy it off shelf or on amazon as well. Just an advice : Better to hire a pro to do it for you. Thanks, Nitin Cornerstone Designs Studio, Bangalore.
