Room Design - Converting Family room into bedroom with bathroom and walk in closet

Hello, I’m looking for assistance converting an existing family room into a bedroom suite. I have the architectural blueprints and an initial concept, but I’m looking for expert guidance to optimize the layout. Specifically, I’d like help with: Determining the ideal size and layout of the bathroom and walk-in closet. Advising where to reduce the existing 6-foot double-door opening to a 4-foot entry while maintaining the best flow and appearance. Recommending the optimal placement of the toilet, shower, vanity, and any linen storage, including appropriate clearances and spacing. Ensuring the overall layout is functional, efficient, and feels high-end. I can provide the existing blueprints and any measurements or photos you need. My goal is to arrive at the best possible floor plan before construction begins. Please let me know if this is something you can help with, and feel free to share examples of similar residential layout or remodeling projects you've completed. Thank you!
