Like the 12.25" width of the cabinets. We bought two of them to fit into a smaller bathroom. They fit just right. Having accurate measurements posted on the website is most important. Only complaint is the time it took to put it together. About 4 to 5 hours for the first one. Part of it is because the height of the cabinet comes in two parts, joined in the middle. Having 2 cabinet doors is good as well. We can hide more things.
