Which is old and which is new?

This is the new one:

Looks like a traffic jam if there are two people using the bathroom. How about exploring other options? Remove tub? Remove make-up area?

The corner shower door is going to get sprayed with water. That is not good.

36" clear is enough space but the new shower looks small for a bathroom remodel. It looks like it's 36" square which is small for a modern master suite. I would go for 36"x60" or 48"x48" but that would get tight with the tub. 36"x48" may be a good compromise if you didn't want to eliminate too much counter. Even though the original plans have the shower at 48"x48" it looks more like 48"x36" but definitely not square. The corner door on the shower looks small also. To me a good walk in shower is probably the most important element in a bathroom.

Agree with other comments, if you have another tub in the house, skip the tub here and put in an awesome shower.

Actually looks like it may be 48" square and I wouldn't be too concerned about congestion, except at the pinch point but how often are two people passing through there at the same time. ( a standard hallway is 36") Also if you get a good quality shower enclosure I don't think the water spray is a huge issue. A nice frameless glass enclosure would look good and keep an open feeling.

I would kill the tub, and put in a longer shower (expand to the right). End that wall with the tall linen cabinet. I would keep the vanity generally where it is, but run it to the left and maybe end with that angled sink. I would only do the lowered makeup area if you're really going to use it - especially since it's in front of a window. And don't give up the closet space!

Fewer things moving, fewer changes to walls means you can spend more money on the tile and finishes...and if a heated floor wasn't already in the plans, that's where I'd put the savings!

Thank you all for your suggestions and ideas.

Originally, I was going to do away w the tub but husband is conventional and wants a tub. I am hesitant to leave it out for resale purposes, however, I do have 3 other standard tubs in the house.

Since the space is not that large, I really think I need the bath to be pretty lux to compete in the market when that time comes. I don't want to make a mistake on such an important space.

I would suggest incorporating the tall linen closet into the regular master closet. That would make it possible to make the shower larger, and put glass where the linen closet was, so you could see out and make the shower feel even bigger. Just a thought.

I would eliminate the makeup station unless it is something you have to have. Start the shower where it is currently but extend it to almost the edge of a free standing slipper tub which will be centered on the window and extending into the room. Use frameless glass around the shower & next to the tub, which will allow you an angled seat in the shower.

Then place the two sinks where they are now extending the vanity space for a tall linen unit. That uses all existing plumbing where it is now. Brings the back of the slipper tub into the middle of the room somewhat. and gives you more space for the shower. It will allow you to update all fixtures.

If you must have more room between the sinks you could move the one sink closer to the linen cupboard or place the linen in between the sinks. Within this upgrade change the toilet to a higher quality ADA height. Update the exhaust fans in the toilet room and the main shower/tub room to have much lower decibals (quieter) within complying to the cubic size of the rooms. They should also be setup to turn off within a certain time limit automatically.

Modify the original layout with modern touches, new plan idea is already outdated.

Tub under window
Shower - same location but glass door & panel.
Freestanding tub
Taller vanity cabinets
Etc

Also change out all towel bars, hooks, toilet paper hardware & the mirrors for separate tall rectangular ones instead of a whole wall of mirror. Update all lighting as it will need to be changed as well. Really do you need a TV in there?

We do not like having a makeup table under a window. Do you have a makeup mirror that sits on the counter. It had better be a good size. Also, why are you specifying a 70" tub in limited space. A 60" tub is fine for this size room.

There may be too much squished into the space. We like the idea of a larger more luxurious shower. The big mistake could be not having a comfortable space by putting too much into it. Here in our area we are eliminating tubs from bathrooms (Master baths specially) all over town. You do have three other tubs after all!

Depending on the layout the shower door could be the center panel of glass as well.

Best wishes.
