New Title

Adding a bathroom, kitchen, or full addition to your home is a major undertaking — and the plumbing is the foundation everything else is built on. Keith Petersen Plumbing handles the plumbing for new bathroom and kitchen additions throughout the Fox Valley and surrounding areas, from the initial layout to the final fixture connection, so your new space is built to code and built to last.

A new bathroom starts below the floor, not above it. We plan and install the complete drain, waste, and vent system, water supply lines, and rough-in for your new bathroom before the walls go up — coordinating with your general contractor, framer, and tile setter so nothing has to be torn out and redone. Whether it's a powder room, a full guest bath, or a master suite addition, we design the plumbing to fit your layout, your fixtures, and your local code requirements.

Once the framing, drywall, and finishes are in, we return to set and connect your fixtures — toilets, sinks, faucets, shower valves, tubs, and appliances — and test every line for leaks and proper flow. Every connection is installed to code and checked before we call the job done, so your new bathroom or kitchen is ready to use from day one, with no callbacks and no surprises.
