I purchased a house that was built in 2009-2011 in California. I want to update the fixture to a brushed nickel finish and leave the valve alone, only because there is no access inside near the plumbing lines only on the exterior of the house (opposite side of the fixture). It is currently chrome with gold. The jetted tub is American Standard if that helps. I do not know where to look for a model number or brand. If someone can assist me in pinning down a manufacturer, and then a replacement if any (in brushed nickel), this would be helpful. Thank you master plumbers!
