I like your inspo photo of the green tile with wood vanity and white marble. I would be afraid to detract from that with another different feature wall in the shower.

I would continue the white marble for the remainder.

Our shower has two 15" wide half walls with glass on top...the door in the middle. We have a white marble vanity top and 12" white marble on the inside and front of the shower walls and it's gorgeous.

You need a single vanity there, not a double. Theres no storage, and its over crowded. 2 people cannot even use that. A smaller vanity with a 6” space gap between it and the shower glass is what works. Or else there needs to be a pony wall between the vanity and shower.

How wide is the vanity as drawn? Do you really need to have two doors into the room?

If the glass will be touching the vanity it may be hard to clean.
Otherwise I’d do floor to ceiling glass.

Agreed with the above re not bringing in another tile.
What will the floor tile be? Can you use that for the walls ?

There are not 2 doors into the room.
The door beside the toilet is a linen closet. I attached a photo for inspiration.
The vanity is 60” with one sink. I was going to do 2 sets of taps.
This is the ensuite to our bedroom.

Also, I have decided not to put a door on the linen closet and just leave it exposed as my inspiration picture.

Your vanity is not in an alcove, with walls bookending it. You cannot do an accent tile wall behind it without doing the whole wall in those tiles. That means the entire wall, from the shower, all the way down. The layout would be greatly improved if the toilet could be located on the vanity wall, facing into the room. The linen cabinet location makes everything awkward. Could it be accessed from a hallway instead?

I’m a little deflated now;(

The vanity was only 60” I was going to only put one long sink with 2 sets of taps. I have considered leaving the linen closet open with a 24” opening. Then I felt there was enough room from the end of the vanity to the wall. I could make the vanity even smaller but I find the pony walls so chunky in a small space. With everyone’s suggestions I feel I am completely wrong in my thinking and choices.

48” is the better standard size, but 54” as a single bowl would work too. No dual bowls, no dual faucets. That will never be functional. 60” is too big for that space without doing a pony wall to butt it to. You cannot butt a vanity to a glass wall unless you want to stare at spiders while you shower.

Can you move the toilet and linen? Can you post the rest of the space the bathroom fits into?

This is the house. The linen space is fixed because it used to be the entry to my basement stairs. We are flipping the stairs and building around the entrance.
A few things have changed on this plan (removed the wall when we enter the house and the breakfast nook.

Flipping the stairs? Oh no no no no no! That is HUGELY expensive because you will now have to meet modern building codes. You will lose space at the top and bottom of the stairs both, and will need to do structural work. There is no pay back to ever touching stairs. It is 50K just flushed down.

I think you need some professional design help, immediately.

Canada not USA. Not the same building codes. It’s not hugely expensive and it’s stairs going into our basement. It’s a small bungalow and the engineer has already inspected and the one supporting LVL beam has already been added.

Green tile on the long shower wall would be a fantastic feature. The eye will be drawn to the length of the room and appear larger. And it's such a great color for a bath.

White marble everywhere else except a light neutral tone for the floors. Very light and airy.

The vanity should not abut the shower stall. Just have all glass as mentioned.

A 4 foot vanity would give you an extra foot of floor space and the shower will appear much more open and the room more expansive.

Canada is even more expensive than the US for constuction costs. Forget changing stairs.

If you are changing the stairs as shown, I would make the closet a coat closet accessible from the foyer . Then as Yonder said, have the toilet at the end of the vanity facing the long wall. Do a 5 foot vanity, a 5 to 6 inch space and then your shower. With 12 feet, you have a lot of room.

I had a five foot vanity with one sink. Lots of counter top and two doors on a 30 inch sink cab in the middle flanked by 15 inch drawers on either side. Lots of storage.

Small bathroom--use wall-hung toilet and floating vanity if you can

This is similar...Gwyneth Paltrow's spa in her Montecito place.

So question. Why do you need the north door into the bathroom? You already have a guest access bathroom, just close that off and move the toilet. Also, why can’t you tile behind the vanity like you wanted, even tho there’s no alcove? People do it all the time. Here’s some examples.

@JD it’s not a door it’s a linen closet

Can you change the layout a bit? To me, this seems much less awkward then what you currently have. Then you could have a deep niche in the shower where the linen closet had been. Here’s my suggestion and a similar layout except flipped. Let me put in the next comment

Here’s the pics

Thank you for taking the time to draw it out. I really appreciate it.
The issue is that I cannot put the shower on that side of the bathroom because it’s the stairwell. That’s why I had decided to put a linen closet in that space.

What do you mean? The staircase is still outside of the bathroom. Are you saying your shower can’t be next to the staircase?

I traced it over your floor plan.

It’s shaped like this

I understand. I didn’t even draw in again where the linen closet was. I moved the shower to where the toilet was. And now in the drawing I just uploaded I put the niche where the linen closet was, but obviously it would only take up a small portion of thay space

Ok I see how you did that. Ok. Thank you very much. I didn’t consider taking more space away from my bedroom, but works very well.

Jenny, also if you wanted to utilize the rest of what was the linen closet under the stairs, you could use it as a coat closet in the foyer (open it up not to the bathroom, but to the foyer).

Yes, we actually split the space and made just enough of a nook in the bathroom told hold towels and a small built in cabinet.
