Abstract: Systems, methods, and techniques for updating and personalizing plumbing fixture assemblies are provided. In some embodiments, a plumbing fixture assembly comprises at least one faucet body and at least one interchangeable annular device. The faucet body is configured to removably couple to a support structure at a proximal end. The interchangeable annular device comprises an interior surface defining an opening and is configured to removably couple to the proximal end of the faucet body. The interchangeable annular device is configured such that when it is coupled to a faucet body, one or more fluid conduit passes from an interior space of the fluid body through the opening of the annular device.
