Fixture-ready block

Brick or block walls are often constructed before fixtures, such as faucets, are installed. Sometimes this occurs because the fixture has not yet been selected, or because an installation location for the fixture is unknown. Thus, workers often need to modify the wall to receive fixtures once selected. However, other times, a builder may know where a fixture should be installed, and the type of fixture it will be. In these instances, a fixture-ready block may be selected based on the type and location of the fixture and installed at the proper location when the wall is built. The block may have apertures with dimensions selected based on a fixture that will be installed in the block. This may eliminate the need to drill or bore through the wall after it is finished in order to install the fixture.
