To be clear, that is a pony wall between the vanity and toilet.

I would not do a shower/tub combo in the master bath. Many people do not like that and as long as you have a bath somewhere else in the house, you should be fine. I would also put the bed on the bottom wall and put windows on either side of the bed. The reason I suggest that is so that one person doesn't have to walk completely around the bed in the middle of the night to get to the bathroom.

I would want a wider closet

how much clothes do you have?

your bathroom looks pretty optimal, and is about as compact as you are going to get it. You could delete one of the sinks, but it won't buy you much space. It could be a foot wider, which will feel roomier, but a big mirror on the vanity wall may have the same effect.

Your bedroom is long enough to have an additional closet near the door, if storage is an issue.

if you swapped the locations of the bedroom and the bathroom+closet, you would have more room for a bigger closet and bigger bathroom, but would end up with a smaller bedroom.

A lot of your dimensions are minimums. I assume the rest of the house is the same. Having space to function is a wonderful thing.

I highly suggest working with a closet designer. Really plan out the space. It's actually fun to do, not a huge expense, and will give you the most efficient space possible, even compact.

Also- imo, you need to think about moisture blocking and insulation features on the wall that separates your closet and bathroom. Heat/steam/moisture transference can be the enemy of a fresh closet. Open walls during construction make this a fairly inexpensive thing to do. You won't regret it.

What is happening on the opposite wall from the bed? With so little space it may be better to split the closet. His/Hers and do a 24" wardrobe ceiling to floor. More European style. Then make your walk in just on one side.

This plan needs more help than a closet designer can provide.

Thanks for the ideas. We added a couple extra feet. One to the closet and one to the bath by expanding the footprint of the home. We are trying to not build more home than is needed and are trying to keep it reasonable in size but not tiny home. I appreciate everyone’s constructive comments.

I’m glad you added the space because I think 2.5 feet between the wall and the vanity is much too small.
