Which fixture is commonly installed during the rough-in phase of plumbing projects?

During the rough-in phase of plumbing projects, significant plumbing fixtures and related infrastructure are installed before the final finishes are applied. A bathtub is commonly included at this stage as it requires extensive plumbing connections for both water supply and drainage. Since bathtubs are typically large and heavy structures, they need to be positioned and connected early in the process to ensure that the necessary piping is appropriately laid out and secured.

This phase involves installing drain lines, water supply lines, and venting systems that will support the bathtub’s operation, which is crucial for the overall function of the plumbing system. Completing this work during the rough-in phase allows for walls and floors to be finished appropriately afterward without needing to disturb established connections.

In contrast, fixtures like sinks, toilets, and faucets are also important, but they are more likely to be installed after the rough-in work is completed and the surrounding areas are ready for the final finishes. The bathtub's specific requirements for plumbing connections make it particularly relevant during the rough-in stage.
