Query: 15 minute installation

What amazed me is the ease of installation and the exact fit on my 100 year old tub. Turned the water off, loosend and removed the nuts to the hot and cold water on the old unit. The new unit slipped right in. Tightened nuts down, turned water back on. Perfect fit and no leaks.Well built, very stylish unit.
