I would like to enlarge the shower and need help with the layout.

The drawing shows the room size after taking down the shower wall and removing the corner tub. I added a free standing tub, a larger shower with frameless glass doors and recessed towers flanking a new 72” vanity. I angled the shower walls to make room when standing in front of the sink. There is approximately 24" between the new tub and shower and I'm concerned it may be too narrow.

This layout doesn’t look optimal to me and I don’t know what options I have without moving the existing plumbing.

I would appreciate any suggestions on placement and sizing of shower and tub.
