Hello! My husband and I are building a house, owner builder. I have a quick and hopefully simple question for you guys. The plumber installed a Delta MuliChoice Universal Rough shower valve (model #R10000-UNBX). I am interested in purchasing a Danze Opulence shower trim kit (Model #FSA-D502057BN) online. It does not come with the shower valve. Is there any way to check to see if these items are compatible? I assume that Delta called it "universal", so it will work. DH doesn't want to spend the cash on the Danze if we can't be positive that it will work. Can someone clear this up for me? TIA!
