Windows in bathrooms are for venting and letting steam out. If husband wants a breeze, he needs to build an outdoor shower.

I’d keep the toilet where it is and relocate the shower across from sinks. Moving the pocket door is typically less expensive thing than moving plumbing.

Here's the plan showing what I was suggesting. I couldn't get it to post before.

With #1 you have the plumbing on an outside wall -- are you in a climate where that is acceptable? Do you have the space for extra insulation, etc? will there be an access panel inside the storage unit? And are you sure you can put in a pocket door with the usual placement of outlets on the side wall by the vanity?

With #2 you need the narrower shower and a sliding glass door, rather than swinging into traffic. Also, I think you need 24" minimum in front of a toilet.

I think Emily is on the right track, but keep your smaller vanity on the toilet side and put your larger shower on the right -- you should be able to move the door over enough to allow for at least 36 inches and possibly more. (You can also look for a vanity with 22" depth instead of 24, which can help with spacing.)

​​​I'd go with your first idea. I would NOT have an operable window in the shower. I'd put a fixed window with glass blocks and install a bathroom fan for ventilation. I think that your double vanity will be cramped.  You might want to rethink the storage. In respect to the toilet placement, you have to consider local building code, which Is likely to require the toilet's center to be 18" from an adjacent wall.

Very much like the suggestion above, but moving the storage next to the toilet.

What abt this?

This way you don’t have to relocate drains & water lines !

Lillyglasgow you read my mind on the industrial paned glass doors. I am trying to find a source for them that is actual panes, not "tape" for the design like at home depot or wayfair. What is the size of the shower you put in there??

We do have the current bathr
oom sink and kitchen sink on exterior walls so that plumbing switch might be possible. Huzzah!  So much better than a solid wall.

I like lillyglasgow’s plan as it is practical and allows for a window for the husband to look out while showering. Husband isn’t going to feel those warm summer breezes unless he lives in the Deep South and maybe on the coast. This is because the water coming down on him will be a stronger sensation than wind and the water will be warmer than the breeze. He can still enjoy looking out the window and maybe watching the curtains in the breeze.

A local glass company should be able to fabricate the industrial paned glass doors

I messed with the dimensions a few times after those screenshots but I have it at 3’3”x 5’ right now. Leaves a 2’6” space between vanity and shower. I think I had it at 4’6” in those pictures

The length^ I left the width the same I believe at 3’3”
