Bathroom Remodeling in Oregon City | Plumbing That Fits Your New Design
We provide Bathroom Remodeling throughout Oregon's Clackamas, Multnomah, Washington, Marion, and Yamhill Counties.
A bathroom remodel changes more than tile and fixtures. Every sink, toilet, shower, and tub connects to supply lines, drain pipes, and venting that may need to be moved, resized, or replaced to match your new layout. Our plumbers handle the full plumbing scope of a bathroom remodel: rough-in, fixture installation, and final connections so the finished room works as good as it looks. We are a family-owned shop in Oregon City with 5.0-star Google reviews. Call (503) 919-7243 or request an estimate online.

Bathroom Remodeling for Oregon City Homes
Bathroom remodeling in Oregon City means handling every piece of plumbing required to transform a bathroom: removing old fixtures and pipe, roughing in new supply and drain lines for the updated layout, and installing new fixtures clean and to code. We handle bathroom remodels across Clackamas, Multnomah, and Washington counties as part of our bathroom remodeling services from our Oregon City plumbing team.
When it is time for bathroom remodeling
If your bathroom layout does not work for how you use the space and you want to move the toilet, vanity, or shower, that requires rerouting supply lines, drains, and venting. If your bathroom still has original galvanized supply lines or cast iron drain pipe, a remodel is the right time to replace all of it. If you are combining a small bathroom and closet into a larger space, the plumbing has to be reconfigured from the ground up. If accessibility is the goal and you need a walk-in shower or comfort-height toilet, the plumbing changes to support those features.
Homes in McLoughlin Historic District and Canemah built in the 1940s through 1960s often have bathrooms with original plumbing that was sized and laid out for the standards of that era. A remodel brings everything up to current Oregon code.
Our bathroom remodeling process
We start with a walkthrough of the existing bathroom to map every supply line, drain, and vent connection. We review your remodel plan and identify what plumbing needs to move, what can stay, and where new lines need to run. We coordinate timing with your general contractor so the plumbing rough-in is complete before walls close up.
During rough-in, we run new supply lines, install drain and vent connections at the correct locations, and pressure test everything before drywall goes up. After finishes are in, we return for fixture installation: setting the toilet, mounting the vanity and faucet, connecting the shower valve, and testing every connection.
Bathroom remodeling cost in Oregon City
A bathroom remodel’s plumbing cost depends on how much the layout changes. A remodel that keeps fixtures in the same positions but upgrades supply lines and fixtures is on the lower end. Moving a toilet, adding a shower where one did not exist, or replacing all drain and vent lines through the floor and walls increases the scope. We walk through the project with you, explain what the plumbing work involves, and give you a price before demo starts. Call (503) 919-7243 to schedule a project walkthrough.
Common Questions About Bathroom Remodeling
How long does the plumbing portion of a bathroom remodel take?
Rough-in typically takes one to two days depending on how much pipe needs to move. Fixture installation after finishes takes another half day to a full day. The total timeline depends on how much of the layout is changing and whether we are replacing old galvanized or cast iron pipe while the walls are open.
Do I need to replace all the plumbing during a remodel?
Not always. If the existing supply and drain lines are in good condition and the fixtures are staying in the same locations, we can connect new fixtures to the existing rough-in. If you are moving fixtures, changing the layout, or the existing pipe is corroded or undersized, replacing it during the remodel saves you from opening walls again later.
Can you work with my general contractor?
Yes. We coordinate with GCs, tile installers, electricians, and other trades regularly. The key is scheduling the plumbing rough-in before walls close and the fixture install after finishes are complete. We communicate directly with your contractor to stay on the project timeline.
Do bathroom remodels need a permit in Oregon?
If the remodel involves moving or adding plumbing lines, yes. Oregon requires a plumbing permit for new rough-in work. Simple fixture replacements on existing connections typically do not. We handle the permit and coordinate the inspection so the work passes the first time.
What is the difference between a bathroom remodel and a bathroom renovation?
A remodel changes the layout, structure, or footprint of the space. That usually means moving fixtures, rerouting plumbing, and sometimes opening or closing walls. A renovation refreshes the look without changing the layout: new tile, new fixtures in the same positions, fresh paint. The plumbing scope is much larger on a remodel.
Can you move my toilet to a different wall?
Yes, but it requires rerouting the drain line and supply. Toilet drains connect to a flange on a specific branch of your waste system. Moving the toilet means running a new drain branch to the new location and tying it into the existing waste and vent system. It is one of the more involved fixture relocations in a bathroom remodel.
Do older Oregon City homes need extra plumbing work during a remodel?
Often, yes. Homes in Park Place, Barclay Hills, and the McLoughlin Historic District with original galvanized supply lines and cast iron drains benefit from replacing that old pipe while the walls are open. It adds to the remodel cost, but it prevents having to tear into the new finishes later when the old pipe fails.
Will you help me plan the plumbing layout for my remodel?
Yes. If you have a design or floor plan, we review it and flag any plumbing constraints or opportunities. If you do not have a plan yet, we can advise on fixture placement based on where existing drain and vent lines run, which can save you money by minimizing the amount of pipe that needs to move.

GASP! I turned the gas, water, and electricity off, and called my contractor for help. Little did I know I would be referred to plumbing specialists extraordinaire, Principled Plumbing.
When Nate (the owner) arrived, he explained the issues, gave me options, and then his crew arrived early the next day to install a tankless heater. They were professional, very personable, and cleaned up spic and span. Nate and his crew stayed late until the job was finished, even though they had to route a new gas line. I 100% recommend them for any of your plumbing needs!
Do not hesitate to support this business!
I will definitely use them again and recommend them to anyone with plumbing issues.
