Which of the following plumbing fixtures is installed during the rough-in phase?

1. Faucet

2. Garbage disposal

3. Showerhead

4. Toilet paper holder

The correct answer is: Garbage disposal

During the rough-in phase of plumbing installation, the primary focus is on setting up the essential systems that will later support the fixtures. This phase involves the installation of pipes, drains, and other foundational elements, which will eventually accommodate the fixtures used in the finished construction. A garbage disposal is installed during this phase since it requires the connection of plumbing lines for both water supply and drainage. This setup ensures that the electrical and plumbing systems are appropriately established before completing the installation of the kitchen sink and countertop. In contrast, fixtures such as faucets, showerheads, and toilet paper holders are generally installed later in the finishing phase, after the rough-in work is completed, as they are surface-mounted and part of the final touches in a bathroom or kitchen. Hence, recognizing the role of the garbage disposal in the construction sequence highlights its placement during the rough-in stage, while the other options pertain to final installation steps.
