Planning bathroom remodeling in Oregon
One statewide code for every city
Homes are built to the 2023 Oregon Residential Specialty Code, which is based on the 2021 International Residential Code and became mandatory on April 1, 2024. Commercial buildings follow the 2025 Oregon Structural Specialty Code, based on the 2024 International Building Code, which became mandatory on April 1, 2026. State law makes the building code uniform statewide, and a city or county cannot enforce different requirements on the same matters unless the state's building codes director authorizes it.
Wet west, dry east, two climate zones
West of the Cascades, rain falls often from October to May, while the eastern side of the state is much drier. The U.S. Department of Energy's county guide places western counties such as Multnomah, Marion, Lane, Benton and Jackson in marine climate zone 4C, and Deschutes and the other eastern counties in cold zone 5B. Residential energy rules are part of the state residential code, which the Department of Energy rates as equivalent to the 2021 IECC. Commercial energy rules follow ASHRAE 90.1-2022.
Cascadia earthquake risk
The Cascadia Subduction Zone is a 700-mile fault about 70 to 100 miles off the Pacific coast, and its last major earthquake struck on January 26, 1700. The Oregon Department of Emergency Management estimates about a 37 percent chance of a magnitude 7.1 or larger earthquake on this fault in the next 50 years. Foundation anchoring and wall bracing are worth reviewing on new construction and major remodels.

Permits
Bathroom work that moves or adds plumbing, adds electrical circuits or fixtures, changes ventilation or alters walls commonly needs a permit and inspections. Replacing a vanity or toilet in the same location may not. Rules differ by jurisdiction, so the local building department confirms what is required for your project.
Contractor licensing
Oregon Construction Contractors Board (CCB)
Oregon requires a Construction Contractors Board license for anyone paid to do construction work that improves real property, including roofing, siding, painting, carpentry, flooring, concrete, heating and cooling, and handyman work. Licensing requires at least 16 hours of pre-license training and a passed exam, a surety bond, liability insurance, and workers' compensation insurance if the business has employees. Only contractors licensed for lead-based paint renovation may bid or work on homes built before 1978, and electrical and plumbing licenses are issued separately by the state Building Codes Division. Before you hire anyone, look up the license on the CCB search. The CCB says a license check shows whether the contractor is actively licensed and bonded and whether proof of liability insurance was submitted.

Permits in Oregon
Building permits in Oregon come from local building departments. Cities that run their own program issue permits inside city limits, the county building department serves most unincorporated areas, and the state steps in where no local program exists. Every department enforces the same statewide specialty codes, but zoning, land-use and project-specific permit questions are handled locally, and some jurisdictions have adopted optional provisions such as the wildfire standards. Permit needs vary by jurisdiction and by project, so they are confirmed for your address during planning, before work is scheduled.

What’s included
Bathroom Remodeling in Oregon: scope and options
- Demolition down to studs and subfloor where the condition calls for it
- Shower and tub installation, including tub-to-shower conversions
- Waterproofing behind tile in showers and other wet areas
- Floor, wall and shower tile installation
- Vanity, sink, toilet and faucet installation
- Exhaust fan installation or replacement, vented to the outdoors
- Plumbing and electrical updates coordinated with licensed trades where required
- Wall blocking for grab bars, plus lighting, mirrors and accessories
Common options
- Tub, shower or both
- Keep a tub for bathing, convert to a walk-in shower for easier access, or install a tub and shower combination.
- Shower base
- A prefabricated pan installs quickly and simply. A tiled base allows custom sizes and low or curbless entries but involves more steps.
- Wall surfaces
- Tile, solid-surface panels or acrylic surrounds. Panels have few grout lines to clean, while tile offers more design choice.
- Vanity style
- Freestanding, wall-hung or built-in, with one or two sinks, sized to the storage you need and the space around it.
- Accessibility features
- Grab bars, a handheld shower, a bench, lever handles and a comfort-height toilet can be installed now or planned with wall blocking for later.
What this service does not cover
- Remediation of widespread mold, which is handled by remediation specialists
- Asbestos or lead-based paint abatement, which is handled by certified specialists
- Replacing main water or sewer lines outside the bathroom
- Repairs to water damage in rooms below the bathroom, unless added to the scope in writing
Budget planning
What affects cost
Layout changes
Moving the toilet, shower or drains means more plumbing and floor work than keeping fixtures in place.
Shower type
Custom tiled showers with niches, benches or curbless entries take more labor than prefabricated units.
Tile selection
Tile size, material, pattern and how much of the walls are covered all affect labor and materials.
Subfloor and framing condition
Water-damaged subfloor or framing has to be repaired before new finishes can go in.
Ventilation
Adding or rerouting an exhaust fan so it vents outdoors can require work through walls, ceilings or the attic.
Fixtures and glass
Shower valve types, specialty fixtures and custom glass doors vary widely.
Access and staging
Tight rooms, upper floors and homes with only one bathroom affect how the work is sequenced.
Scheduling
What affects the schedule
- Whether this is the only bathroom in the home
- Custom shower glass, which is measured after tile is complete
- Special-order vanities, tile and fixtures
- Inspection timing for plumbing and electrical rough-in
- Drying and curing time for waterproofing, mortar and grout
- Water damage found after demolition
How to prepare
- If this is your only bathroom, arrange another place to shower during the key stages
- Remove toiletries, towels, rugs and anything stored in the vanity
- Choose tile, vanity and fixtures early so they arrive before demolition
- Note any current leaks, ceiling stains in the room below, or soft spots in the floor
- Think about future needs, such as grab bars or a step-free shower
Process
How Bathroom Remodeling Projects Work
- 1
Consult
We look at the room, check for signs of leaks and soft spots in the floor, and talk through who uses the bathroom and how. Storage and accessibility needs come up here.
- 2
Plan
We settle the layout, tub or shower, tile, fixtures and ventilation, and write down the scope. Fixtures and tile are selected and ordered before demolition so the room is not left open waiting on materials.
- 3
Build
Demolition, plumbing and electrical rough-in, and inspections come first. Waterproofing is installed and checked before tile covers it, followed by fixtures, glass and trim.
- 4
Enjoy
A final walkthrough covers how fixtures and the fan work and how to care for grout, stone and glass. Punch-list items are completed before closeout.

Questions
Bathroom Remodeling FAQs
Can I convert my tub to a walk-in shower?
In most bathrooms, yes. The drain location, floor framing and wall conditions decide how simple it is. A low or curbless entry takes more floor work than a shower with a standard curb.
Why does waterproofing matter if tile resists water?
Grout and many tile materials let some water pass through over time. A waterproofing layer behind the tile keeps that water out of the walls and subfloor, where it would otherwise cause rot and mold.
Do I need a bathroom exhaust fan?
A fan that vents outdoors removes moisture that would otherwise collect on walls, ceilings and inside cabinets, leading to peeling paint and mold. Whether a fan is required depends on local code and whether the room has a window that opens.
What if this is my only bathroom?
The work can be sequenced to limit how long the toilet and sink are out of service, but there will be stretches without a working shower. Decide where you will shower during those stages before work starts.
Should I choose a prefabricated shower or tile?
Prefabricated units install faster and have few seams to clean. Tile gives more size, shape and design choices and allows niches and benches. Both perform well when installed correctly.
Can grab bars be added later?
Yes, if solid blocking is installed inside the walls during the remodel. Adding blocking while walls are open is simple compared with cutting into finished tile later.
