I have an ample sized bathroom on my floorplan, but I'm having difficultly finding a layout I like.

The interior walls are 10'-4 long by 8'-6 wide. There is a window along one short wall and a door along the other short wall, but the placement of those is flexible. The width can flex by maybe 4" either way. This is for a new construction, so plumbing, etc. can go anywhere.

I want to fit a toilet, a 60" tub, a 3x4' shower, and a minimum 4' vanity with a single sink. A linen closet would be nice. All fixture sizes are flexible, but for budget reasons I need to stick with standard sized fixtures.

One other consideration is that I am designing the ground floor to be mostly wheelchair accessible. The bathroom doesn't need to be accessible now, but if it could be modified later with a minimum of construction and costs that would be a huge plus.

This the best I've come up with, and I don't like it much. Anyone have any better ideas?
