My husband installed this sin his bathroom in the shop. He said it was very good quality and he was very pleased with it. He said the direction very consumer friendly and he was able to install it with no issues. He loved the fittings and said that he was glad they were not cheap plastic fittings that you see alot of these days with many products. Delta is a trusted brand at our house and we use many of their products because of the durability and the materials they use for their products.
