Serden Group serves Portland, OR homeowners with full-service bathroom renovations — custom showers, tubs, tile, fixtures, and everything in between. Licensed, bonded, and locally trusted since 2015.
Portland homeowners deserve a bathroom they love — we understand City of Portland permit requirements, older home plumbing layouts, and what it takes to deliver a stress-free renovation.
Portland homeowners have dealt with contractors who over-promise and disappear. We built Serden Group differently — one local team — an in-house crew supported by licensed, vetted trade partners and coordinated by one project manager — that handles your bathroom from the first call through the final inspection. Permitted, inspected, and explained as we go.
We visit your Portland home, walk the bathroom, discuss your goals and budget, then map out a realistic plan — including which City of Portland permits the work will need.
We design a layout built for how your household actually lives — factoring in your home's existing structure, plumbing runs, and Pacific Northwest style preferences.
We pull the permits, coordinate our crew and trade partners, and keep you updated daily — no surprises on the final bill.
Why Homeowners Choose Serden
"From start to finish, the team was professional, reliable, and detail-oriented. The quality of their work is outstanding — everything from the tile installation to the cabinetry and finishes looks beautiful. They completed the project on time and within budget, which is rare to find these days."
We handle every aspect of your bathroom remodel in-house — design, demolition, plumbing, tile, and finishing — so nothing falls through the cracks. Replacing only the shower? See shower remodeling in Portland.
Most of what decides the price and the schedule of a Portland bathroom is settled before any tile is chosen: what the work changes, what the house is hiding, and which permits that triggers. These are the six things we walk through at the first visit.
Inside Portland city limits, permits come from Portland Permitting & Development. The city's guidance is that a bathroom remodel may need only trade permits — plumbing, electrical and mechanical — when you move or add fixtures, outlets, lights or the fan. Moving walls, changing a door or window opening, or touching load-bearing framing adds a building permit and plans. Like-for-like finish work, such as new flooring or a vanity top on existing plumbing, usually needs none.
Much of Portland's housing stock is decades old, and older bathrooms often hide aging galvanized supply lines, cast-iron drains, undersized or missing exhaust ducting, and floors that have moved out of level. None of that shows on a walkthrough. We note what we can see, tell you what we expect to find, and price discovered conditions openly rather than burying them in an allowance.
Under the EPA's Renovation, Repair and Painting rule, paid work that disturbs painted surfaces in a home built before 1978 has to be done by a certified firm using lead-safe practices. If your house predates 1978, plan on containment and cleanup steps during demolition, and ask how they will be handled.
Keeping the toilet, vanity and shower drain where they are is the single biggest saving. The price climbs with relocated plumbing, a tub-to-shower conversion, the area and pattern of tile, a curbless entry that has to be recessed into the floor, custom glass, heated floors and a new vent run to the exterior. The ranges further down this page show where typical scopes land.
Construction time depends on scope, but the calendar usually slips for three reasons: permit review and inspection scheduling, special-order items such as vanities and shower glass (glass is measured after the tile is set, so it arrives last), and conditions found at demolition. Making selections before demolition starts keeps the bathroom out of service for the shortest time.
Many Portland projects turn a hall-bath tub into a walk-in shower, or rework a primary bath around a larger shower. Whether the entry can be curbless depends on the floor framing below it. Our guides to curbless showers and tub-to-shower conversions cover the tradeoffs; shower remodeling in Portland covers shower-only projects.
Permit requirements change. Portland reorganized its permitting bureau into Portland Permitting & Development, and its own pages note exceptions, so we confirm the current requirements for each address. Homes outside Portland city limits — Lake Oswego, Beaverton, Tigard and others — are permitted by their own city.
