Residential and commercial restroom plumbing fixtures are often compatible and can be used in either home or business applications. The type of fixture and how it is installed is the largest factor when considering a fixture for each. In general, the fixtures, equipment, size and materials are the same, but there are many commercial applications that are not practical in a residential home, according to Lifetips.com.
The biggest difference between residential and commercial bathroom fixtures is the amount of use the fixture receives and the water usage the fixture requires per use. Commercial bathrooms are created to be more efficient than residential sinks and toilets. There may be other differences, depending on the fixture and application. For best results, consult a plumber who is proficient in both residential and commercial plumbing.
