Get rid of the gas chamber, locate a smaller shower on interior walls, allow space to clean around the freestanding tub, and provide as many windows as privacy will allow.

Half wall by the toilet instead of a separate water closet.

Placing the linen closet in the water closet is a sure way to keep your linens wet and smelly. It's a bad idea--find another builder. Good luck!

Virgil - Agreed! Unfortunately, we've signed a contract and have to make it work. We will keep working on the layout until we're satisfied. Thanks for your feedback!

Bri - It looks narrow to us as well. The builder said the width of the bath is actually wider than how it looks there It should end up being about 10' wide, leaving 3' between the corner of the shower and vanity top.
