And a mock up of the larger cabinet

I think the larger cabinet fills the space better. Then maybe a similarly framed piece of artwork to the right? Or maybe even two cabinets?

I'd cut a big ol' hole in that wall and create a recessed, shelved closet with double doors, like this, only larger and with doors

Thanks, I would love something like that but there is a pocket door behind that space and an electrical panel on the section where the tub is.

Will definitely balance the cabinet with art or open shelves or - something. I am leaning towards the larger one, always better to have more storage. :-)

How about adding a long white shelf across the top of the doorway and further across the room for small items ....

...and add white shelves (perhaps two) across the whole wall area just above the wall handle? You could plan the depth of the new shelves to hold gray baskets or even fabric-covered boxes .....

Floating shelves are an interesting idea for that wall. I was thinking more of chunky wood ones in weathered tones to match your tile as opposed to one long white shelf as teacarts is suggesting, but that's definitely something to think about. As is whether you want a mirror right by your tub like that.

Will a big one create a conflict with the grab bar? You want to be able to grab it, not carefully insert your hand.

Be sure that when you open the door, it doesn't knock into the grab bar.

Think about what kind of storage you need--for small toiletries that would go in the cabinets you are considering? Or do you need to store larger things such as towels that would look nice on an open shelf, or toilet paper that needs to be hidden?
The white shelves would blend in nicely with your trim and tub. What color is your vanity?

It seems like an odd place for a medicine cabinet, which usually is placed near the sink or counter. I know you want to keep the floor clear, but I would put a tall, narrow cabinet there.

And I am wondering how that grab bar is going to help anyone in or out of the tub, given how the tub appears to be sloped at that end.

i would take the grab bar down...it is so far away from the tub....is this some code issue?

and i would go with the larger cabinet

Between those, I like the big one better.

Is there room for a medicine cabinet above the sink or to a wall by the sink?

I would go with the larger cabinet. The towel bar being smaller than it will look better than it being bigger than the cabinet. Open shelving is a nice idea but I would rather close my stuff up because you know eventually it'll be a mess... or at least in my house it would : ) nice to close that stuff off.

Is it possible to find something similar without a mirror? I prefer the large size, but not sure about having a mirrored cabinet there. Especially if you plan to hang artwork next to it. I too would remove the grab bar. agree with others it doesn't seem to be close enough to be of use.

How much storage space do you have with your vanities? I can understand your not wanting to cover the beautiful tile and have a standing cabinet. It really depends on what you plan/need to store in the wall-mounted cabinet. And what other options might be available; i.e., a custom-made cabinet or wall-mounted shelf system you might find at Ikea that could be made useful with storage baskets or bins to meet your needs.

"Be sure that when you open the door, it doesn't knock into the grab bar."

Look at the photo again.
Or read post #5.
:)

:-), Yes it is a pocket door. The grab bar is really adjacent to the tub, it just looks further away in the photo and it works quite well; I just use it to steady myself as I step out. The curved lip on the tub is great for grabbing.

I've always had a charming little sideboard in that space with a mirror above it but we had a more traditional drop in tub in the old bathroom. I find the sideboard is in the way now and takes away from the shape of the new pedestal tub.

I am just going to use this cabinet for smalls, things I don't want to bend down to get. I have a linen closet adjacent to the bathroom and plenty of space in the vanity cabinets and drawers for things like TP.

I wish I could find a cabinet we like w/o a mirror but have not found the "perfect one." Years ago I had a wonderful antique medicine cabinet (no mirror) and when we sold the house the buyers made sure it was included it in the contract. It really was beautiful and the whole family keeps saying "if only we still had the old one." LOL

Pretty sure I don't want many open shelves, the less I have to dust the better.

So many good ideas, so much to think about......

These may be to rustic/primitive for you but it's something to look at and maybe consider similar options if you don't like the one you have picked out with the mirror. That is a pretty piece though you have picked.

I would not want a mirrored cabinet in that space, large or small. Here is an option for much less money and no mirror - you can find this almost anywhere:

Have both sizes in my house- go with the large. The small is teeny tiny.

I think it will look lovely with the large one and compliment the room very well. It's important that the room function the way you want. I like it,

pps7 - Thank you, I'm glad to hear that first hand.

Sasafras - that one was my first choice but we just didn't like the construction when we saw it in person.
