Tile Installation Mercer Island WA

Tile installation · Mercer Island, Washington

Waterproofed first. Tiled second.

Searching for tile installation near me on Mercer Island? Under the original 4×4 tile, a sixty-year-old Mercer Island rambler keeps its secrets — and the tile was never doing the waterproofing anyway; that duty belongs to the membrane behind it. Our order of work: open the bath, report honestly on the subfloor, build the assembly, hold a photographed 24-hour flood test, and set tile last of all.

How much does tile installation cost on Mercer Island, WA?

Mercer Island tile lands, installed, at roughly $14–$26 the square foot — the sum of tile, thinset and setting materials, substrate preparation and labor, where labor by itself enters at $11/sq ft. A tub-shower surround of standard scope opens near $3,200 and crests around $6,800; a full bathroom build — floor, shower, niche — finishes anywhere from $6,500 up to $14,000. Mid-century houses hide their swing in substrate prep, so we look first and price after, never the reverse.

File under counterintuitive: what shape the tile takes moves your bill further than what it costs. Install day can price a $4 mosaic sheet above $12 large-format porcelain, since the hours pool in cuts and grout lines while the tile receipt stays a footnote.

The part you never see

What's behind a shower that lasts

Seven layers from joists to grout. Every failed shower we open on the Island is missing at least one — nearly always the membrane, cut once to save a few hundred dollars, opened later at a five-figure cost.

Why it matters

A leak gives no warning. Water slips past grout, soaks into the substrate, and in a daylight rambler shows up a floor below — a ceiling stain in the rec room, a soft spot by the hallway — two years after the fact. The repair by then is framing, subfloor, drywall and the whole tile job again.

Waterproofing is about a tenth of what a shower costs. In a 1965 house it's also the difference between a remodel and a future excavation.

Scope & starting prices

What we tile on Mercer Island

Starting rates — format, layout complexity and, on the Island especially, substrate condition move them. The firm number gets written on site, free.

Most requested

Shower & bath tile

A shower is a system first — base sloped, membrane bonded, flood test filed on record — and only then a niche, a curb or curbless entry, and tile. The layer that vanishes is the layer you're buying.

from $3,200 / shower
Floors

Porcelain & stone floors

From bathrooms and kitchens to entries, mudrooms and lower-level slabs. First the subfloor is flattened — corrected outright if needed — then uncoupling membrane goes wherever movement or heat mats require.

from $11 / sq ft labor
Kitchens

Backsplash

Subway, herringbone, mosaic sheet or slab-look porcelain. Outlet cuts tight, edges trimmed, grout picked against the counter rather than out of the box.

from $1,100 / backsplash
Upgrade

Heated tile floors

Radiant electric mat on an uncoupling membrane, resistance verified before setting and again after, on a dedicated circuit. Only rational while the floor is already open.

from $11 / sq ft added
Repairs

Tile repair & regrout

Cracked field tile, chalky grout, corners letting go. We measure, tap and tell you plainly: repairable, or substrate already past saving.

from $8 / sq ft
Prep

Demo & haul-away

Original tile, mud bed or backer out under sheeting and negative air, joists inspected while they're visible, debris hauled. Driveway left empty.

from $3.50 / sq ft
Material guide

Which tile, and where

Tile regret on Mercer Island rarely traces to cheap tile; it traces to good tile put on the wrong surface. Below, the two-minute edition of the advice we'd deliver in your bathroom.

Material
Best for
Avoid
What it costs you later
Porcelain
$3–$14 / sf
Floors, shower floors, wet rooms, high traffic
Nothing structural — it is the default for a reason
Least maintenance of anything here. Under 0.5% water absorption.
Ceramic
$2–$8 / sf
Walls, backsplash, tub surrounds
Floors, and anywhere heavy things get dropped
Chips show the clay body underneath. Cheap to buy, cheap to replace.
Natural stone
$8–$30 / sf
Feature walls, entries, statement floors
Shower floors and kitchen backsplash behind a range
Needs sealing every 1–3 years. Marble etches from anything acidic.
Glass mosaic
$10–$28 / sf
Niches, accent bands, backsplash
Floors — and any large uninterrupted area
Labor-heavy to set, but nothing else holds colour like it.
Zellige / handmade
$14–$40 / sf
Backsplash and walls you want to look alive
Anywhere you want a perfectly flat, uniform surface
Variation and lippage are the point. Budget extra labor, not extra tile.

Material-only rates, installation excluded. We bring samples and give you the unvarnished view of which ones earn their price.

Schedule

A bathroom, day by day

A typical Island bathroom needs four to six working days — more when the subfloor has news to share. Credit the two patient mid-week days for why the work endures.

01
Demo & protection
Floor paths covered, doorways sheeted, negative air on. Old tile, thinset and backer out to bare framing, and the first honest look at the subfloor.
02
Substrate & waterproofing
Rot repaired, backer board set, pre-slope built, membrane bonded and every corner and penetration sealed. Then the flood test goes in and sits overnight.
03
Flood test cleared, tile starts
We photograph the test, drain it, and start setting — layout dry-laid first so cuts land where you'd want them, not where they fall.
04
Tile finished
Walls, floor, niche and edge trim complete. Large format back-buttered, lippage checked as we go rather than at the end.
05
Grout, silicone, done
Grout, then silicone in every change of plane. 24 hours of cure before you use the shower, and we walk it with you before we invoice.

How much does tile installation cost on Mercer Island, WA?

+

Sum tile, setting supplies, substrate preparation and labor on Mercer Island and the result reads roughly $14 to $26 for the square foot, installed; on its own, the labor component enters at $11 per square foot. Surrounds for the standard tub-shower open near $3,200 and crest around $6,800, while a complete bathroom — floor, shower and niche — finishes anywhere from $6,500 up to $14,000. Format is the multiplier hiding in plain sight: mosaic sheets and oversized planks alike demand notably more labor per square foot than a plain 12×12 grid.

How much does it cost to tile a shower on Mercer Island?

+

On Mercer Island a standard alcove shower opens near $3,200 and crests around $6,800, a figure that folds in demolition, the bonded waterproofing, a sloped pan or base, the tile itself, the niche, the grout. Benches, curbless thresholds, steam and full-height stone raise it — so does structural correction where a 1960s bath has seen water before. Call the waterproofing a tenth of the bill; it's the tenth that spares you the tens-of-thousands repair.

Do you waterproof showers before tiling?

+

Yes — arguably it's the whole job. Under every shower goes a bonded waterproofing build: base sloped before membrane, the membrane brought wall-high, corners, seams and pipe penetrations sealed, and then a 24-hour flood test recorded in photographs before tile is allowed on. Water moves through grout and tile freely; the membrane is what protects framing that has stayed dry here for sixty years and ought to keep doing so.

How long does a bathroom tile job take?

+

Give a Mercer Island bathroom four to six working days. The sequence: demolition under dust control; substrate correction and membrane work, the flood test standing its own 24 hours between; setting across a day or two; the closing pass of grout, silicone and trim. First use waits 24 hours while grout cures. Should demolition turn up subfloor repairs, you hear about it that same day, priced — never as an end-of-job surprise.

Porcelain or ceramic tile — which is better?

+

Porcelain for every floor and wet area: under 0.5% water absorption, denser and more chip-resistant than ceramic. Ceramic is a fair economy for walls and backsplashes. In mid-century Island baths we specify porcelain underfoot and in shower floors without exception, and let ceramic or glass argue for wall space.

Can you install a heated tile floor?

+

Yes. Heated tile figures at $11 up to $16 for the square foot, installed, thermostat within the price — and over a crawlspace or daylight basement it's the least expensive cure a cold mid-century floor can get. The mat lies on uncoupling membrane, has resistance confirmed before setting and confirmed again after, and is fed from a dedicated circuit of its own. The window for it closes when the floor closes.

Do I need to remove the old tile first?

+

Usually, and on the Island especially. Removal and haul-away run about $3.50 per square foot, and demolition is the only honest look at a 60-year-old subfloor — rot, movement, past leaks — plus the only way to hold floor height at doorways. Tiling over existing tile on a flat, sound, bonded floor is possible, but it buries exactly the evidence we want to see.

How much does a kitchen backsplash cost on Mercer Island?

+

Thirty square feet of Mercer Island kitchen backsplash goes in for $1,100–$2,200, with outlet cuts, trimmed edges and grout keyed to the counter as part of it. The premium end of that spread belongs to herringbone, mosaic sheeting, framed details at the range and slab-look porcelain — what you're paying for is layout and cutting hours rather than fancier tile.

Can you fix cracked tile or regrout instead of replacing?

+

Often, and we'll say when. Repair and regrout start at $8 per square foot — appropriate for stained or crumbling grout, a few cracked tiles from an impact, or corners needing silicone in place of grout. Hollow-sounding tile, a pattern of loosening, or a wall that flexes means the substrate is finished, and repairs only rent you time. We diagnose first, quote second.

Which Mercer Island neighborhoods do you tile?

+

The whole Island — Town Center, First Hill, East Seattle, Roanoke, Mercerdale, Mercerwood, Barnabie Point, Faben Point, Proctor Landing and The Lakes, North End to South End — plus Enatai, Beaux Arts Village, Newport Shores, Bellevue and Seattle over the bridges.

What warranty comes with tile installation?

+

A 2-year workmanship warranty stands behind our tile — carpet gets half that, because tile defects favor year two over week two. Where a manufacturer's bonded system goes in complete, the maker's own coverage applies alongside. And since your membrane and flood test were photographed, the record survives — small engineering history worth having when an Island house changes owners.
