Remodel division
Remodel Plumbing
From a fixture swap to a bathroom or kitchen that moves to a different wall. Home additions and light commercial included, out of the same Racine shop since 1978.
Chapter 01
Moving a bathroom versus swapping a fixture
The Karlsen Plumbing Service and Remodel division will handle anything from a simple fixture upgrade project to a newly located bathroom or kitchen. Swapping a faucet or a toilet where the rough-in already exists is a different job than relocating a bathroom to the other side of a Racine house, and both the price and the schedule start with figuring out which one it actually is.
A straight fixture swap can often go in against the same day's supply and drain lines, using brands like Kohler, Moen, Delta and Grohe. Moving a kitchen or bath means new drain, waste and vent piping has to find its way to a stack that was never built to serve that spot, which is where a remodel stops being a parts job and starts being a real plumbing layout problem.

What opening up an older Racine wall actually turns up
Racine has a lot of housing built well before modern plumbing codes, and once a wall comes open on a remodel, what is behind it is rarely what the plans assumed. Galvanized supply lines narrowed by decades of mineral buildup, cast iron drain lines rusted thin, or a vent that was never run to code all turn up more often than a homeowner expects.
That is why this work gets scoped by a licensed Wisconsin plumber who has actually opened these walls before, not off a set of drawings alone. Fixture and finish work draws on trusted names, Kohler, Sterling, InSinkErator, Rinnai tankless water heaters, Uponor PEX and Watts, so what goes back into the wall is built to outlast the pipe that came out of it.
Chapter 03
Light commercial work and home additions
The same remodel division takes on light commercial plumbing and home additions, not just residential kitchens and baths. A home addition needs its water, drain, waste and vent piping tied into the existing house correctly, sized for the new fixtures rather than just stretched off the nearest line.
Karlsen Plumbing has run this kind of work out of 1951 Grove Ave in Racine since 1978, and it is the same crew of Wisconsin licensed plumbers doing remodels, additions and new home construction. That means a light commercial buildout gets handled by people who already know how to tie new work into an old system without surprises. Call (262) 633-1951 to talk through a project before it starts.
