Gresham & East County, OR

A bathroom remodel that finally handles Oregon humidity

The fiberglass surround, the strip of vanity lights, the fan that never cleared the mirror — that combination is in half the bathrooms in East County. Replacing it well means getting waterproofing and ventilation right, not just picking tile. Send your project and licensed Gresham remodelers respond with scope and pricing.

Tub-to-shower conversions

This is the most common request in Gresham's hall and primary baths, and it does more for daily use than any other single change. The work involves reframing the curb or going curbless, moving the drain, and rebuilding the wall behind. If anyone is aging in place, plan blocking for grab bars now while the wall is open — it costs almost nothing at this stage.

Waterproofing is the part you cannot see

Tile is decoration; the membrane behind it is the actual shower. Sheet or liquid-applied waterproofing over the backer, correct pan slope, and a properly bonded drain are what keep water out of the subfloor. Ask each bidder to name the system they use. A contractor who says green board and mastic is quoting a failure you will discover in five years.

Ventilation, because this is Oregon

Nine months of damp air and a builder-grade fan is why so many local bathrooms have peeling paint and mildew in the ceiling corners. A properly sized fan ducted out through the roof or wall — never dumped into the attic — solves it. A humidity-sensing switch takes the human out of the loop, which matters more than people expect.

When a bathroom needs a permit here

Swapping fixtures in place is usually straightforward, but moving drains or vents, altering framing, or adding circuits requires permits from City of Gresham Development Services, plus separate plumbing and electrical trade permits. Unincorporated addresses go through Multnomah County. Confirm your contractor's Oregon CCB registration before any deposit.

What is behind the walls in 70s and 80s homes

Expect a one-piece fiberglass unit that has to be cut out, a plywood or particleboard subfloor with a history of leaks at the toilet flange, and sometimes cast iron drain stubs. Rot at the flange and along the tub apron is common enough that a good bid includes an allowance for subfloor repair rather than pretending it will not happen.

Crawlspaces, cold floors, and freeze risk

Most local bathrooms sit over a vented crawlspace, so supply lines in exterior walls can freeze during Gorge outflow cold snaps. A remodel is the right moment to insulate those runs and the floor cavity. It also makes heated tile floor a much better performer, since you are not warming the crawlspace along with your feet.

What a bathroom remodel costs in Gresham

A hall bath refresh — new vanity, toilet, lighting, paint, and flooring with the layout untouched — typically runs $8,000 to $16,000. A full gut with a tiled shower, new plumbing fixtures, and proper ventilation more commonly lands between $20,000 and $38,000. Primary suites with double vanities, curbless entries, and custom glass frequently exceed $45,000. Subfloor rot and relocated drains are the usual overruns, so ask how those are priced before signing.

What homeowners say
They found rot under the old flange, showed me photos, and repaired the subfloor before tiling. I would rather know than have it buried.
Sofia K.Centennial · Full bath gut
Turned our unusable tub into a curbless shower and put in a fan that actually clears the mirror. No more mildew in the corners.
Duane W.Gresham Butte · Tub-to-shower conversion
Moving the shower drain meant a permit, and they pulled it and scheduled the inspection without me chasing anyone. While the floor was open they insulated the supply lines running out to the crawlspace.

Frequently asked questions
How long will my bathroom be out of service?

A fixture-level update is often a week to ten days. A full gut with tile typically runs three to five weeks once demo starts, since waterproofing, mortar, and grout each need cure time. If it is your only bathroom, plan accordingly.

Is a prefab shower base cheaper than a tiled pan?

Yes, usually by a meaningful amount, and a quality acrylic base is a perfectly good product. Tiled pans buy you custom sizing, curbless entries, and a seamless look. Neither leaks if it is installed correctly, and both leak if it is not.

Can I add a bathroom in my basement or garage?

Often yes, though drain height decides the approach. If the existing line sits above the new fixtures you will need an ejector pump or an up-flush system. It is permitted work in Gresham and worth having a plumber assess before you commit to a layout.

What causes mildew to keep returning on my ceiling?

Almost always undersized or improperly ducted ventilation. Check whether the fan actually terminates outside rather than into the attic, and whether it moves enough air for the room's volume. Fixing that is far cheaper than repainting every other year.

Do I need to move the toilet to change the layout?

Not always. Vanities and showers have more flexibility than the toilet, whose drain is the most expensive fixture to relocate. Many good Gresham remodels leave the toilet where it is and rearrange everything else around it.
