Bathtub Replacement in Oregon City | Out With the Old Tub, In With One That Works
We provide Bathtub Replacement throughout Oregon's Clackamas, Multnomah, Washington, Marion, and Yamhill Counties.
A cracked, stained, or leaking bathtub is not just an eyesore. A failing tub drain or overflow damages the subfloor underneath, and an old tub that does not drain properly makes every bath a frustration. Our plumbers remove the old tub, adjust or replace the drain and overflow assembly, connect supply lines to the new faucet or valve, and make sure everything seals and drains correctly. We are a family-owned shop in Oregon City with 5.0-star Google reviews. Call (503) 919-7243 or request an estimate online.

Bathtub Replacement for Oregon City Homes
Bathtub replacement in Oregon City means removing the existing tub, inspecting and repairing the subfloor if moisture damage is present, and installing a new tub with proper drain, overflow, and supply connections. The plumbing work includes setting the new drain shoe and overflow assembly, connecting the P-trap to the waste line, and hooking up the faucet or tub valve. We replace bathtubs across Clackamas, Multnomah, and Washington counties as part of our bathroom remodeling services from our Oregon City plumbing team.
When it is time for bathtub replacement
If the tub has a crack that lets water seep into the subfloor, replacement is the only permanent fix. Refinishing covers cosmetic damage but cannot repair structural cracks. If the drain is slow and cleaning does not help, the drain shoe or waste arm may be corroded and part of the tub assembly needs replacing. If you are switching from a standard alcove tub to a freestanding or soaking tub, the drain position and supply line routing change. If the tub surround is pulling away from the wall and water gets behind it during every shower, replacing the tub and surround together stops the damage.
Many homes in McLoughlin Historic District and Park Place still have original cast iron or steel tubs from the 1950s. These tubs are heavy, and the drain fittings underneath corrode over decades of use. When the drain starts leaking through the floor, it is time.
Our bathtub replacement process
We start by disconnecting the drain, overflow, and faucet connections. We remove the old tub, which may require cutting an access panel or removing part of the surround. Once the tub is out, we inspect the subfloor for water damage and replace any rotted sections before setting the new tub.
We level the new tub, install the drain shoe and overflow, connect the P-trap, and hook up the faucet or valve. For freestanding tubs, we route supply lines to the floor or wall position required by the filler. We fill the tub, check every connection, and confirm the drain and overflow both flow properly.
Bathtub replacement cost in Oregon City
A standard alcove tub swap where the new tub fits the same opening and the drain lines up is the most straightforward job. Switching tub types (alcove to freestanding, for example), repairing subfloor damage, or rerouting the drain adds to the scope. We assess the situation, explain what the plumbing work involves, and give you the price before we start. Call (503) 919-7243 to schedule.
Common Questions About Bathtub Replacement
How long does bathtub replacement take?
The plumbing portion typically takes one day: removing the old tub, inspecting and repairing the subfloor if needed, setting the new tub, and connecting all plumbing. If wall or surround work is involved, add time for those finishes.
Can I switch from an alcove tub to a freestanding tub?
Yes. The main change is the drain position and how supply lines reach the filler. Alcove tubs have wall-mounted faucets; freestanding tubs need a floor-mounted or wall-mounted filler with supply lines routed to the new position. We handle the plumbing reconfiguration.
Will you check the subfloor when you remove the old tub?
Yes. A leaking drain or overflow can cause moisture damage to the subfloor that you cannot see with the tub in place. We inspect the plywood and framing once the old tub is out and replace any rotted material before setting the new tub.
Can you replace a cast iron tub?
Yes. Cast iron tubs in older Oregon City homes are heavy (300 to 400 pounds) and often require cutting into sections for removal. We handle the demo, haul-away, and installation of the replacement. The drain fittings on cast iron tubs are typically corroded and get replaced along with the tub.
Do I need to retile the surround when I replace the tub?
If the new tub is the same size as the old one, you may be able to keep the existing surround. If the tub is a different height or width, or if tile was damaged during removal, the surround will need to be redone. We coordinate with tile installers if needed.
What is the difference between bathtub replacement and bathtub refinishing?
Replacement removes the old tub and installs a new one with fresh plumbing connections. Refinishing coats the existing tub surface to cover stains, chips, and discoloration. Refinishing works for cosmetic issues but cannot fix cracks, structural damage, or failing drain assemblies.
Do homes in Clackamas County have specific tub plumbing issues?
Older homes in the county, especially those built before the 1970s, often have galvanized drain fittings and brass waste arms that corrode over time. When we replace the tub, we replace the entire drain and overflow assembly with modern materials so the new installation lasts.
Can you install a soaking tub or Japanese-style tub?
Yes. Deeper tubs require verifying that the drain and overflow can handle the increased water volume and that the floor structure supports the added weight when full. We check both before installation and make any adjustments needed.

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.
