Essential Aspects of Rough Plumbing for a Bathroom Double Sink

Installing a double sink in your bathroom requires careful planning and execution, particularly when it comes to the rough plumbing. Rough plumbing refers to the underlying infrastructure that supports the visible fixtures and appliances in your bathroom, such as sinks, toilets, and showers. In the case of a double sink, the rough plumbing involves the water supply lines, drain lines, and the necessary fittings to connect them.

To ensure a successful double sink installation, several essential aspects of rough plumbing need to be considered:

Water Supply Lines: The water supply lines provide cold and hot water to the sink faucets. These lines should be sized appropriately to deliver sufficient water flow and pressure for both sinks. Typically, 1/2-inch copper or PEX piping is used for residential applications.
Drain Lines: The drain lines carry wastewater away from the sinks and into the main drain system. Proper drainage is crucial to prevent clogs and backups. The drain lines should be sloped slightly downward to facilitate water flow and should be sized to handle the volume of water discharged from both sinks.
Trap and P-Trap: A trap is a U-shaped fitting that prevents sewer gases from entering the bathroom. It is installed beneath the drain lines and holds a small amount of water, creating a barrier against gases. A P-trap is a specific type of trap commonly used in bathroom plumbing.
Faucet Connections: The faucet connections provide water from the supply lines to the sink faucets. These connections typically involve flexible hoses or rigid copper lines and should be secured properly to prevent leaks.
Shut-Off Valves: Shut-off valves are installed on the water supply lines near the sink. They allow for the water supply to be turned off for maintenance or repairs without affecting the rest of the plumbing system.

By carefully considering these essential aspects of rough plumbing, you can ensure a properly functioning and aesthetically pleasing double sink installation in your bathroom.
