Tile installation · Sammamish, Washington
Waterproofed first. Tiled second.
Plateau bathrooms work hard — two kids brushing teeth over one floor, muddy cleats in the hall bath, a master shower running twice a day. Tile handles that life only if the layer nobody sees is right, because tile and grout themselves are not waterproof. We build the bonded assembly, leave it under water for a documented 24 hours, photograph the proof, and then start setting.

How much does tile installation cost in Sammamish, WA?
All-in Sammamish tile pricing runs from $14 up to $26 a square foot — tile, setting materials, substrate prep, labor — and labor accounts for $11/sq ft at minimum. Tub-shower surrounds mostly price inside $3,200–$6,800, and a bathroom taken all the way — floor, shower, niche — usually settles at $6,500–$14,000.
The plateau surprise: what a tile costs per box predicts less than what shape it comes in. A modest mosaic sheet can eat more labor than a premium large-format plank — installers charge for the cutting and the joints, and mosaics multiply both.
Current Sammamish ranges as of August 2026, covering tile plus materials plus labor. Treat these as planning numbers; the free in-home estimate produces the real one in writing.
What's behind a shower that lasts
Count up from the framing and a shower is seven layers before you reach grout. When a plateau shower fails early, the autopsy always finds a missing layer — the membrane most often, skipped once to save a few hundred dollars and repaid later at fifty times that.
No shower leak ever knocks on the door. It works quietly — through the grout, into the substrate — until a kid asks why the hallway floor feels soft or a stain blooms on the family-room ceiling. The invoice at that stage covers framing, subfloor, drywall and tiling the whole thing again.
Call waterproofing a tenth of the shower's cost. On a busy family shower, deleting that tenth is the priciest savings you will ever be offered.
What we tile in Sammamish
Starting numbers only — the tile's format, the substrate we uncover and the layout's complexity all move them. The binding figure is written at your home, at no charge.
Shower & bath tile
Everything under and behind the tile done right: pre-slope, bonded membrane, the overnight flood test, then the niche, curb or curbless entry you actually wanted. The invisible work is the product.
Porcelain & stone floors
Ensuite floors, kitchens, mudrooms that see soccer season, basements. We flatten first and add an uncoupling membrane where movement or a heating mat asks for it.
Backsplash
Subway, mosaic, herringbone or slab-look — cut precisely around plateau kitchens' many outlets, edged with real trim, grouted to match the counter rather than the box label.
Heated tile floors
Radiant mats under tile, tested for resistance before and after setting, on a dedicated circuit with its own thermostat. Worth it exactly once: while the floor is already open.
Tile repair & regrout
A cracked tile from a dropped cast-iron pan, stained grout, corners releasing in a shower. Straight answer every time on whether repair holds or the base beneath has already gone.
Demo & haul-away
Old surfaces stripped to sound framing — thinset, backer and all — with sheeting and negative air keeping the dust out of the playroom, and every scrap hauled off the property.
Which tile, and where
The plateau's most common tile mistake is a beautiful choice asked to do the wrong job. Here is what we would tell you in your own bathroom, condensed to a table.
Prices shown are for material alone. We arrive with samples and honest opinions about where each one is worth its rate.

Scope, square footage, tile format, prep — the identical arithmetic we do on site, minus the driving. A planning tool, not a contract.
A bathroom, day by day
Sammamish bathrooms book four to six working days. Two of them — membrane day and flood-test day — look uneventful from the hallway, and they're the reason the shower outlives the kids' graduations.

What Eastside clients keep saying
“They placed plastic sheeting over the cabinets to contain the dust, so we noticed hardly any. The floors look as good or better than new.”
“We chose them because they were professional and top-notch. The work was smooth, fast and cost-effective — such skill and precision!”
“The installers were great! The floor is exactly what we wanted. We worked with OC Flooring previously — highly recommend.”

How much does tile installation cost in Sammamish, WA?
Complete tile installation around Sammamish falls in the $14–$26 range per installed square foot — tile, setting materials, prep, labor — with labor from $11 per square foot as the floor. A standard tub-shower surround will quote between $3,200 and $6,800; take the bathroom to completion with floor, shower and niche and it generally lands at $6,500 to $14,000. Format deserves your attention: mosaic sheets and oversized planks each cost real extra labor per foot compared with 12×12.
How much does it cost to tile a shower in Sammamish?
Sammamish alcove showers in standard form ask $3,200 to $6,800. The figure wraps in tear-out, the waterproofing system, a sloped pan, tile setting, niche and grout. Benches, steam, curbless entries or stone to the ceiling move it upward. Waterproofing is maybe ten cents of every dollar — modest insurance against the one failure with a five-digit price.
Do you waterproof showers before tiling?
Without exception. Cement board alone is not waterproofing — our showers get a bonded membrane system: pre-sloped base, sheet or liquid membrane run up the walls, corners and pipe penetrations sealed to TCNA / ANSI A118.10 practice, then a 24-hour flood test that we photograph before any tile is set. Grout only slows water down; the membrane is what stops it reaching your framing.
How long does a bathroom tile job take?
Most Sammamish bathrooms run four to six working days: day one is demolition and dust control, day two builds substrate and waterproofing and starts the overnight flood test, setting takes one to two days after the test clears, and grout, silicone and trim close it out. Give the shower another 24 hours of cure before anyone uses it. Standalone floors: one to two days.
Porcelain or ceramic tile — which is better?
Family floors and showers want porcelain — under 0.5% water absorption, denser body, far harder to chip when something gets dropped. Ceramic is the economical pick for walls and backsplash duty. In Sammamish homes we default to porcelain anywhere feet or water go, and let ceramic and glass fight over the walls.
Can you install a heated tile floor?
Happily — an electric radiant mat prices at $11–$16 for the installed square foot, thermostat counted. Under it goes an uncoupling membrane; around it, resistance checks before setting and after; behind it, a dedicated circuit. This is the plateau's school-morning favorite, and the economics only close while the floor is already up.
Do I need to remove the old tile first?
Nine jobs in ten, yes. Figure demo plus haul-away near $3.50 the square foot — the only route to a genuine subfloor inspection for rot or movement, and the way floor heights stay sane where doors swing. Now and then a truly flat, solidly bonded floor can take tile over tile, but that buries exactly what we'd want to find at demolition rather than after grout day.
How much does a kitchen backsplash cost in Sammamish?
For the typical 30-square-foot kitchen, Sammamish backsplashes price at $1,100 to $2,200 with outlet openings, trimmed edges and counter-matched grout in the number. The upper end belongs to layout-heavy work: herringbone, mosaic sheets, a framed feature above the range, slab-look panels run full height. Hours of cutting and layout put them there, not the tile itself.
Can you fix cracked tile or regrout instead of replacing?
Frequently, yes — from $8 per square foot. It is the right call for stained or crumbling grout, one or two impact-cracked tiles, or shower corners that need grout swapped for silicone. It is the wrong call when tiles echo hollow underfoot, keep popping in a pattern, or the wall flexes — that is substrate failure, a repair only postpones it, and we will tell you which situation you have before we price anything.
Which Sammamish neighborhoods do you tile?
The whole plateau: Klahanie, Sahalee, Trossachs, Pine Lake, Beaver Lake, Inglewood Hill, Timberline Ridge, Heritage Hill, Aldarra, Montaine, Chestnut Estates, East Lake Sammamish and Providence Point, plus Issaquah Highlands, Redmond Ridge and Fall City next door — and Issaquah, Redmond, Bellevue and the broader Eastside beyond.
What warranty comes with tile installation?
A 2-year workmanship warranty rides with our tile — set past the carpet term on purpose, because the second year is when tile acts up, not the second week. Manufacturer waterproofing assemblies installed complete carry the maker's system warranty too. The photos we keep of membrane and flood test mean the paper trail survives any future sale.
