Hi! Thank you for your interest in our Peerless PTT298510-BN Choice Brushed Nickel Roman Tub Faucet Trim. In general, you have to take into consideration the following. First, the handles and handle flanges. Second, the spout adpater. If your classic faucet is Delta and the top of the adapter measures 3/4" diameter, then this Peerless PTT298510-BN will work fine. Hope this helps! If you're interested in purchasing the Peerless PTT298510-BN, just click the "Add to Cart" button, enter your zip code and you'll be all set. Thank you for visiting PlumbersStock.com. Have a wonderful day!
