We are installing new shower and are looking at thermostatic valves. Ultimately, we’ll have a rain head from the ceiling. Plus a handheld. We also have a Kohler steam unit. Our plumber loves Brizo but we are having a hard time finding right combo for what we like. We’ve come down to Kohler and Graff. Love the quality and feel of Graff. However, Graff is more expensive. Also, we really love that Kohler comes in 2.5 gpm everything while Graff is lower flows. Any insights here? We are leaning toward just going with the Kohler. Thanks!
