I'd probably rotate the toilet to face the shower if you can and then move the cabinet closer to the toilet. Keep the toilet space 36 inches to 42 inches wide. I would make the cabinet 18 inches by 36 ins. or you could just do a 24 inch deep tall cabinet next to the toilet.

Thank You. I like the idea of turning the toilet and moving the cabinet. It would open the space up more. There is plumbing issue though. The floor joist are double (3') wide 12" OC running East to West so the toilet would need to be either 15" or 22 1/2" from the wall. Here it is at 22 1/2" and the cabinet 44" from the wall.

We want to keep the toilet hidden from the vanity.

Other thing we are looking at is increasing the space between the vanity and the bath. This could be done with a 3 sided (less chance of leaks) tub or a 66" wide vanity.

The new layout looks better to me.

How long is the wall with the vanity?

How long will the tub be? Where will the tub filler and faucet sit?

We laid things out full size on the floor last night. The new layout is better!

The wall is 128"

We'd like a 72" tub. The width could be ??

Faucet could be deck or wall mount. No plumbing for it yet.
