What do you plan to do with the second bedroom? Three rooms look as though they give way to the sun room. Could the second bedroom be made more useful as a WIC/dressing room plus storage?

Do you need double doors to the Master? If you eliminate the door on the left, your door will now open into the side wall of the walk in closet vs. the awkward space that you have now. Then, you could create a second entrance into the bathroom, eliminating the compartmentalizations of your sink from your bathing area. Another option, although others will say it shouldn’t be done, is to change access into the closet so that you enter from the bath, vs. the bedroom. Food for thought?

Sorry...when writing I couldn’t access your posted photo to reference it again. I now see that your entrance to the closet is already from the bath. You could swap it to the bedroom, if that is something you desire.

As mentioned above, you could make your current closet a walk though, turn the entry door, and create a reach in closet across the sink almost the same size as the second bedroom closet.

An even better layout with more storage to consider, is borrowing some space from the bedroom to create a hall to the bathroom flanked by to large reach in closets. You could also put a door and have it a walk through closet:

Generally speaking it seem like things would fit better if flipped ..open kitchen and living room on the left bedrooms and baths on the right
