Many thanks for all the comments. What a pleasure getting some unbiased points of view! This has really helped, so thanks your so much.
Clarification to the question posed:
Re 1'-8" door into the bathroom, , oops. that was not drawn to scale ; was intended to be 24" - still small but doable- that's what we have now.
Re the grey box in the shower - yes that a bench
Re Plan A corner tub not making sense in an alcove, agree- that was my concern, makes more sense to put the shower there. Toilet doesn't work in that large area as it leaves me no spot to place the tub or shower.
Re Plan A shower door too close to toilet - agree
Re Plan A/C dark grey box behind - that's an existing bulkhead - can be removed ( I assume there is nothing behind it)
Re the floor joist direction, based on that fact the I see a floor register parallel to the vanity, I assume the joists run parallel to the short walls.
Re number of drawings, I only showed the most recent three - must have gone through a dozen already , so I am almost at 20
Re it being hard to gauge eithout knowing what is around the outside of the room, fair comments. Its an ensuite as part of the bed room. I am constrained by outside walla, hallways and steps. Tried to show this in the revision below.
Based on the comments and some re-thinking, we are now on Plan D !!
- leaves the toilet as is
- puts the shower in the alcove by the entrance (still plenty of room for a large 5' x 3' shower with bench). Door not near toilet.
- put the tub approx where it is today, but
- centered in the area (bulkheads removed)
- freestanding configuration (vs todays drop-in). Looking at Neptune Ulysse
- 6 foot tub in an 8 foot space.
- wall to have cutouts/ledges (either between the studs or vis a fake wall in front).
- going for the 'look' per the pic below. That pic has the side bulkhead (my plans don't), which is why I slid the vanity out a bit
- not sure if we can pull off that arch without blowing the budget
Any cautions I should be aware of re Plan D?
