Can you use an over-the-door version to avoid this issue?

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.

Hello Abhinav, It would depend upon your requirements from the area. It could be used made as a Pooja room, Study room, Utility and Storage, Playroom or a Bar cum entertainment area. Thanks, Nitin Cornerstone Designs Bangalore.

Hello Neetu Singh, This is my idea to increase the width of your house plan lobby.1.Exchange the positions of kitchen(8'.0" x 12'.0") and small bedroom(8'.4.5" x 11'.9"). 2. Exchange washroom and pooja room positions too and open the pooja place, this will make the lobby more spacious and welcoming as this(pooja area) will be in front of main door entrance(As mentioned in my plan). 3. Idea for small room Please check Above mentioned photos. Thanks, Baljt.
