Sump Pump Selection: Things To Know

Residential Plumbing: Adding Bathrooms

The addition of a new bathroom to a home is one of the most popular renovation projects. It not only enhances the comfort and convenience of your living space but also significantly increases your property's value. However, expanding your home's plumbing network is a complex task that requires careful planning and professional execution. 

Planning and Design

The first step in adding a bathroom is to consider the space where you intend to build it. Ideally, the new bathroom should be located close to existing plumbing lines to reduce the complexity and cost of installation.

Your design should consider the position of fixtures such as the sink, toilet, and shower or tub, which will dictate the plumbing configuration. Take note of building codes and regulations in your area that may influence the design, such as required distances between fixtures, and venting requirements.

Water Supply and Drainage

The water supply and drainage are critical aspects of bathroom plumbing. For the water supply, you'll need to connect your new bathroom to the existing water supply lines. The size of these lines is crucial for ensuring adequate water pressure. Your bathroom will need a wastewater outlet connected to your home's main drain line. The size of the drain lines will depend on local codes.


All bathroom fixtures need venting to maintain proper drainage and prevent sewer gases from entering your home. This usually involves connecting your bathroom fixtures to vent pipes that lead to the roof of your home. Your contractor or plumber will know the appropriate size and type of venting required based on local codes and the specifics of your project.

Professional Plumbing Installation

When adding a bathroom to your home, it's strongly recommended to hire a professional plumber. They can ensure that the project complies with local building codes, the new plumbing is correctly integrated with your existing system, and potential issues such as leaks, or inadequate drainage are preemptively addressed.

Professional plumbers will handle the rough-in plumbing stage, which involves installing the water supply, drain, and vent pipes before the walls and floors are finished. They will also install the bathroom fixtures once the bathroom is close to completion.

Before you can use your new bathroom, a plumbing inspection is typically required to ensure everything is up to code. An inspector will examine the bathroom to verify that all fixtures, pipes, and connections are correctly installed and working correctly.
