We have no idea. We need pictures and a to scale floor plan. I see no need for a alrge vanity in a PR but I have no idea how big the space is . Post a to scale floor plan show doorway and where the toilet is now. Post here in jpeg format in a comment DO NOt start another post . Pictures also posted here in a comment.I do not see the need for solid wood so explain that.

I am wondering if a wall hung cabinet 32 inches wide would work. Ikea has some.

Anything wider would not give you enough space around the cabinet.

Your kitchen designer also might be able to do a 40 inch wall hung cabinet.

Personally, I don't think a stock cabinet would looks as nice.

I would make the decision on whether or not you need a lot of storage.

if so, a vanity to fill the space. It's an opprtunity for something pretty, rather than utilitarian, a free standing dresser turned into a sink base with just the basics needed to store, hand towels, toilet paper, the minimum. a free standing pedestal sink would be great. a powder room is a chance to create a more glamorous space. chandelier, wall sconces, dramatic wall paper, paint, statement artwork. a space that will not be abused.

@Lyn i like this. We really don’t need storage in there beyond some extra rolls of toilet paper. This wasn’t something we budgeted for, and only thought about it due to refinishing all the wood floors in the house. I was wondering if cleaning a pedestal is a pain, and thats why I was leaning towards a vanity or cabinet.

a pedestal is easy to clean, the porcelain finish just wipes off with a soft cloth.

it's a piece of art in itself.

Should you decide on a pedestal with exposed plumbing, take care to use good looking plumbing such as this one has.

Consider pros and cons overall, as I don’t think room will feel larger/smaller by your style choice. Narrowing down based on functionality is how I’d decide, as finishes and decor will have more impact than the size of vanity.
