These are gorgeous! The square base is actually smaller looking in person. The main photo to me makes it look very large and bold it is actually quite small. Perhaps about 3 - 4 inches or so. I do not have it in front of me at the moment to measure exactly. Just guesstimating off of memory. I am very happy with these over all. Moen is a great brand for bathroom pieces and generally comes with a lifetime warranty so definitely a brand I am happy buying.
