Rated 5 out of 5 by from Icing on the cake upgrade Never needed a diverter before but it has been the upgrade I never knew I needed. Love the finish and my plumber prefers working with delta products.

Rated 5 out of 5 by from Easy ordering and exactly what we wanted I was happy to find a kit with all of the pieces I needed for our bathroom in one place, and especially grateful that I did not have to think hard about which valves were needed. Having all the parts ready in one package was wonderful.
