Tile is the visible half of a shower. The half that decides whether your joists rot is the membrane behind it, and that's where the difference between setters shows up five years later. Describe the shower, floor, or backsplash you have in mind and we'll match you with tile installation crews in Portland who build the substrate properly.
A modern shower is a bonded waterproof assembly — sheet or liquid membrane, sealed corners, a properly sloped pan, and a curb detail that doesn't wick. Tile and grout are not waterproof and never were. When you compare bids, ask which membrane system they use and whether they flood-test the pan. The setters who answer instantly are the ones you want.
Floor tile over old Portland framing needs a stiff substrate — an uncoupling membrane or proper backer board over adequately sized joists — or you'll get cracked grout lines within a season. Natural stone adds sealing and, for marble, a maintenance conversation most people would rather have before installation than after. Backsplashes are the quickest win in the house and a good way to test a setter's cut work.
Where the cuts land, how the pattern meets the niche, whether the grout lines run out of square with the room — that's what your eye catches every morning. Century-old Portland bathrooms are rarely square, so a good setter plans the layout to hide the discrepancy in the least visible corner. Ask to see the layout marked out before adhesive goes down.
Describe the project once and we match it with vetted local pros who actually do this work — you choose who to hire, or nobody at all.
In a climate with this much winter humidity, a shower that can't dry out grows mould in the grout no matter how good the tile work is. An exhaust fan sized for the room and ducted outside — not into the attic, where a surprising number of Portland fans still terminate — protects the installation. Raise it with your contractor while the walls are open.
Pre-war Portland bathrooms often have undersized joists, a layer or two of previous flooring, and a soft spot around the old toilet flange. Tiling over that guarantees cracks. Expect a competent setter to check deflection and either add a layer, sister joists, or tell you the floor needs work before quoting the pretty part.
Labour for standard floor tile commonly runs $10–$18 per square foot, with mosaic, herringbone, and large-format work priced higher because of the cut and levelling time. A full tiled shower including waterproofing frequently lands between $3,000 and $8,000 in labour before material. Backsplashes often total $800–$2,000. Natural stone and intricate patterns push all of these up. Substrate repair is normally extra and honest bidders flag it as a possibility rather than absorbing it into a suspiciously round number.
He flood-tested the pan and left it overnight before tiling. Nobody who quoted us before had even mentioned doing that.
Our 1913 bathroom floor was nowhere near square. The layout he chose puts every awkward cut behind the door and it reads perfectly straight.
Marble backsplash with an outlet in an awkward spot. He shifted the layout so the cut tiles land at the ends and the pattern stays centered behind the range.
Usually four to seven working days for demolition, substrate, waterproofing, setting, and grout, with cure time built in between steps. Anyone promising a finished shower in two days is skipping something that needs to dry.
Cement grout benefits from it, especially on floors and in wet areas. Epoxy grout doesn't need sealing and resists staining, at the cost of a harder installation and a higher price. Neither substitutes for waterproofing behind the tile.
On some floors, technically yes, but it raises the height at doors and transitions and buries whatever condition the old substrate is in. In a shower it's a firm no — you cannot inspect or repair the waterproofing under existing tile, and that's the part that fails.
Tile itself generally doesn't. But if the work involves moving plumbing, altering a shower pan drain, or changing framing, that portion is permitted through Portland Permitting & Development. Most bathroom retiles that stay in the same footprint don't trigger it.
