I prefer plan A. Is it for 2 people? Do they use it at the same time? I would want the sink to be in the center of the counter so each person could have a side for their things.

If you choose A, then I would center the sink so that the person using has more room behind them.

a. i wont want to see the toilet first

And center the sink

How much space between the vanity and shower? It doesn't look like it's enough anymore.

Neither Plan A nor Plan B. Everything looks like it is cramped into the space, with no focal point to the room. What fixtures are you willing to move? Are you adding a 2nd window?

Maybe something like this:

The biggest concern is the space in front of the toilet. The code is that you need 22" clearance in front of the toilet. My powder room is 4'2" deep and I just barely have 22" clearance. In your case, with this layout you have 1" to spare (maybe less if the wall between the tub and the toilet is more than 4" thick).

BTW, the space I used for this layout is 95"x138" (I added 4" for the wall between the closet and the bathroom). So I am not sure if in total you have 134 or 138 inches available.

EDIT: If your japanese tub is slightly bigger than 40", a tankless toilet could help preserving the 22" required in front of the toilet:

EDIT2: To make it more open, the wall separating the tub and the toilet does not need to be full height. It could be just high enough so that you don't see the toilet when seated in the tub.

I know this is not helpful at all and I see why you want to redo your bathroom, but I gotta say it is so freaking cool as it is. What an awesome bathroom. I can't figure out if it is deco or 80s or what.

Hi, thank you for ALL the inputs, they were really helpful.

I am inclined to go with A, because I was stayed in a place where the shower was fat and space between the wall and the shower was narrow and tiny. Functional but definitely felt cramped.

Also, as pointed out, tub deck needs to have a bit of a width. 40" wide, but with a deck, 42-45.

Unfortunately I still may have to move the door a little. Existing tub is narrower than 3 feet.

How much space should I have behind a vanity? How wide should the vanity be?

Thank you those photos! I'm now trying to figure out the adjacent shower door config, and it's really helpful. Apologies for the delay in reply.

Picture of the bathroom at where I stayed. Shower was nice and roomy for me (3' x 4.75 ') but I was struck by the narrowness of the entry way

Personally, I would use a regular tub that is roomy and easy to get in and out of. Do an alcove tub deep soaker with the controls on the pony wall between the shower and tub.

Then across from the tub, the toilet and a 24 inch wide linen cabinet to match the vanity.

Then you should have room for a 72 inch wide vanity with two sinks.

Have you ever used a Japanese soaking tub? when I really thought i wanted one my designer suggested trying one out. I found a boutique hotel that had them and I hated it! We have a deep soaker tub/ shower combo in the hall bath so opted to add a better and bigger shower instead of having a tub in the master.

This was the best decision ever as two years later,in my 40s, I suffered a massive stroke effecting my balance and motor skill prohibitting my ability to use such a tub entirely. So glad I 86 the tub!
