Thanks for the drawing. Most people asking for us to magically make the insides of their bathrooms larger than the outsides usually don't give us the drawings.

I think your best bet is to make that window into a door and put the shower in the addition you are building.

Go back and read what you wrote. You don't want to give up any vanity space. You want MORE vanity space, because you want to add a tower. You want a free-standing or tiled-in bath, both of which take up more room than the alcove bath you have.

And you want to add a shower, a walk-in shower. To me, that means a shower so big that you don't need a door. You can have that if you give up the walk-in closet.

All of it.

Most of that is needed for a tiled shower with enough room that you don't need a door, and the rest is needed for the toilet you are moving to get a larger vanity. Or you can have his and her vanities and leave the toilet where it is.

there is a huge amount of wasted space in the doorway (this happens a lot. Get rid of all the angled walls and the triangle closet and you will free up enough room to expand your vanity and to add the shower. Your "ensuite" door will face the living room. If you dont like this, you can make the smallest alcove possible to give a side entry.

Expanding the closet allows you to use pocket doors (I just pasted doors). The pocket doors will let you expand the shower to the max size possible and minimizes space consumed by the door opening.

Personally I would not want my master bath to open to the living room. I would cut the "ensuite" enough to add a half bath and make the only entrance to the master bath through the master closet. My preference would be not to go through the closet to get to the bath though.

I'm not following...

or understanding:-)

You apear that you are trying to put 25# in a 10# bag. Just not going to all fit if I understand you correctly.

I had the same idea as Anthony. Put in a hallway to your MB about 42 inches wide and then a hallway about 38 to 40 inches wide to the closet and master bath.

Master closet should be 7 feet wide by about 8 feet long and bath a little over 7 1/2 feet wide by 12 feet long.

This gives this bathroom/dressing area more privacy from the living room, although the bedroom a little less so.

Use an alcove soaking tub 34 X 60 with a linen closet to the left. Long vanity on the outside wall and 36" X 54" shower with toilet to the left.

That leaves a vanity about 6 feet long.

Your architect or builder should work with you. This a very rough idea.

I really like this layout! I'm going to need to think about this

But can you really just up and move a fireplace? How do you know that it does not have an immovable brick chimney going up through the house? Is there something about the drawing that indicates that it is a faux fireplace?

Karenseb's plan really uses the space well, if you can do things like move the fireplace. It is so much better than the original plan.

When I was trying to see where to fit all that was wanted, I was trying to figure out what the two small triangular spaces were for. Once is a closet of some kind, opening into the living room, the other does not have an opening. Is there something in this space? Water heater? Ductwork? Do architects put triangular dead spaces and odd triangular tiny closets in for no reason? I could see the tiny closet being for AV components, but the dead space?

Edit:

Wait ---Charmar77, is this house built yet? I thought we were remodeling an existing home. If Karenseb is moving the fireplace that easily, maybe it is still in the planning stages?

we can pretty much move anything:-) . this house isn't built yet

Have you posted in the Building a Home forum? There are architects there. I know you had layout issues in your kitchen too. Start there and then the bathroom and kitchen forums can help tweak those rooms.
