I know that this is an issue that arises for many people when you try to renovate a space, or try to squeeze in an extra bathroom or powder room. Often, we find ourselves constrained by the space and a typical bathroom vanity is too large for the space. Some will go with the small corner sink which is not ideal in terms of function. Most, like me, want a full sized sink that doesn’t feel like a small sink. My bathroom project will allow for a 24″ wide sink / vanity, but the depth (from the wall to to the front of the sink) needs to be very small. I was able to locate a sink from IKEA that worked perfectly for my space. Maybe this will work for your small bath renovation as well.
The sink is their LILLÅNGEN sink. The link below (click on the image) shows you the wall mount version, but if you want some storage, they even have an inexpensive vanity cabinet that can be used with or without legs. This cabinet is made to provide a little storage an allow for the plumbing to run behind.

I would strongly recommend that you purchase your faucet directly from IKEA as well. We purchased the Krakskar, along with our sink, at a price of $39.99. For that price, I expected a run-of-the-mill, marginal quality, lightweight faucet. Boy, was I surprised. This was a quality faucet that included the unique drain plug setup (not even needed since the sink ships with one) and even came with braided supply lines pre-installed. In addition to that, the single hole faucets are not common and are a bit pricey. Click the image (below) for a direct link to the Krakskar faucet.
Here is a photo of our Lillangen Sink. This is located in a cottage with a 5′ x 5′ bathroom. We choose to wall mount the cabinet without legs.
