Thank you for asking, we purchased them through a national chain; Ferguson, but believe they are available in other places as well. Here is the model # info for the trim (shown):
8” multi-function rain showerhead model #S6320 with standard shower arm model #S177 and “Twist” handheld with slide bar model #S3870 in chrome by Moen.
I hope this is helpful!

What is the name of the countertop?

The countertop is: Colonial
Golden Cream granite with polished finish and demi-bullnose edge. Please visit and see in person your granite before purchase....since it is milled from the earth, each piece can look different.
