Luxurious, complete, solid-brass faucet set. Outstanding build-quality, finishing process, and appearance. This can be used for residential or commercial applications. This faucet is as easy to install as any standard faucet, and complete instructions are included. Please note that sensor faucets do not have hot & cold handles, so they are usually installed with cold water only, or with an optional mixing valve, which mounts under the sink and connects to the hot and cold water source, and has a set control to proportion the hot & cold into one source for the faucet to use.
