A tiled shower is only as good as the membrane you will never see. Get that wrong and you find out five years later when the subfloor gives. Whether it is a shower, a heated bathroom floor, or a kitchen backsplash, describe the space and local tile setters will quote the work.
The substrate must be stable and flat, wet areas need a complete compatible waterproofing system, movement joints and transitions must be planned, and the setting materials must match the tile and assembly. Verify these layers before finish selection drives the bid.
The assembly matters more than the tile. A bonded sheet or liquid membrane over cement backer, a properly sloped pan, and a compatible drain is the modern standard. Curbless entries need the slope built into the framing, so that decision has to happen before demolition. Ask which waterproofing system a setter uses and whether they follow the manufacturer's full detail.
Large-format tile is unforgiving of a wavy subfloor, and Gresham homes over crawlspaces frequently have deflection and dips. Flattening with self-leveler or mud is often part of a proper quote. Layout matters too: starting from the wrong wall leaves a sliver cut in the most visible spot. A good setter dry-lays and shows you the plan first.
A kitchen backsplash is a one- or two-day job and the highest-visibility tile in the house, which is why cut quality around outlets and at the range hood is what you are paying for. Handmade and glass tiles take longer and need different setting material. Bring the exact tile to the quote if you can, because it changes the labor.
Electric mat systems under bathroom tile are popular here for good reason, since tile over an unconditioned crawlspace is cold from October to May. It needs a dedicated circuit and a proper thermostat with a floor sensor. Coordinate the electrical before the tile goes down, because retrofitting the circuit afterward means opening walls.
Record substrate flatness, movement, moisture and repairs before setting material is placed. For showers, identify the complete compatible membrane, drain, slope, corners, penetrations and test procedure. For heated floors, coordinate the properly licensed electrical work and retain resistance tests before, during and after tile placement. Photograph concealed layers, approve changes in writing and keep inspection, product and warranty records at closeout.
Use measured reference lines to review focal walls, grout alignment, edge cuts, niches, doorways and transitions to adjacent flooring. Large-format tile and irregular handmade pieces require different allowances for flatness and variation. Record the agreed grout width, pattern direction, trim profiles and where the layout begins. Check door and appliance clearance against the finished assembly height. A dry layout or marked drawing gives the setter and homeowner the same visual target before mortar makes the decision expensive to change.
After required cure time, inspect movement joints, grout, sealant, drains, transitions, heat controls and adjacent finishes. Test heated-floor operation and retain resistance readings, electrical records and thermostat information. For wet areas, keep membrane photographs, test or inspection evidence and product details. Label spare tile by room and batch, and provide cleaning guidance that matches the grout, stone and sealer. Tie final payment to a resolved punch list and complete record package, not solely to the day the last tile is set.

With a wet season that runs most of the year, a shower that never fully dries between uses will find any flaw in the waterproofing. Failed installs here usually show up as loose grout at the corners, a musty smell, or soft flooring outside the shower door. Those symptoms mean water is already in the assembly.
Local bathrooms of that vintage were often tiled over green board with mastic and no membrane at all, which was standard practice then and a known failure mode now. When that tile comes off, expect to find damage at the base of the walls. Budget for wall and subfloor repair rather than assuming a clean substrate.
Tile contractors need Oregon CCB registration; tile work itself rarely needs a permit unless plumbing or framing changes, which go through City of Gresham Development Services or Multnomah County. In homes built before the mid-1980s, old sheet flooring and its adhesive under the tile should be tested for asbestos before removal.
| Condition | Likely path | Evidence required |
|---|---|---|
| Sound dry substrate | Prepare and install new finish | Flatness and movement check |
| Wet-area remodel | Rebuild waterproofed assembly | Drainage and flood-test plan |
| Loose or cracked tile | Investigate before replacement | Substrate and movement findings |
| Heated floor | Coordinate electrical and tile layers | Licensed trade and resistance tests |
| Older concealed materials | Test before disturbance | Documented sampling decision |
Reliable pricing follows demolition limits, substrate findings, waterproofing, tile format and layout, setting materials, regulated trades, protection, disposal and closeout. Do not rely on unsupported local ranges when the concealed assembly is unknown.
Look for grout that keeps cracking in the same corner, tiles that sound hollow when tapped, staining on the ceiling below, or flooring that feels soft just outside the shower. Any of those is worth investigating before you spend money on cosmetic regrouting.
Sometimes on floors if the existing tile is solidly bonded and flat, though it raises height and affects door clearance and thresholds. In showers it is a bad idea, because you inherit whatever waterproofing failure is underneath. Removal is the safer path in wet areas.
In showers and heavy-use kitchens, many homeowners find it is, since it resists staining and does not need sealing. It is harder to work with and costs more in labor. For a low-traffic backsplash, standard cementitious grout is usually fine.
Generally several days after grouting, since mortar and grout both need cure time and sealants need to set. Rushing it can pull tiles loose or leave you with hazing in the grout. Your setter should give you a specific date, not a guess.
Some coordinate it, many do not. Valve bodies and drains need to be set before the walls and pan are built, so if you are changing fixtures, that plumbing has to happen first. Mention any fixture changes in your request so the sequence gets planned properly.
Photograph substrate repairs, reinforcement or uncoupling layers, shower slope and membrane details, penetrations, drain connection and heated-floor layout and test readings.
Use the appropriately licensed electrical contractor and identify permit, inspection and testing responsibility before the tile setter covers the system.
Set a written stop point and require photographs, measured repair scope, material specification, price and schedule approval before additional work proceeds.
