What is the quality and material of Kingston Brass' tub faucet?

Kingston's tub faucets are nearly all manufactured from solid brass. The main faucet bodies, waterways, and handles are all brass. A small handful is constructed of both brass and zinc alloy, another highly resistant metal. Other materials in our tub faucets, such as porcelain or acrylic, are accent materials on small parts such as handles.
