Porcelain Tile Installation
Denser than ceramic, frost-proof, under 0.5% water absorption — porcelain handles wet areas, high-traffic floors, and outdoor applications that ceramic can’t. Rainwood Construction installs porcelain tile with the substrate prep and technique the material demands.

Why Porcelain Is Harder to Install Than It Looks
Porcelain is fired at higher temperatures than ceramic — denser body, lower porosity, harder surface. That’s what makes it perform. It’s also what makes it punishing to install wrong.
The density that resists water also resists bonding. Unmodified thin-set won’t grab it — modified is mandatory. Large-format porcelain (24×48, 32×32) flexes under its own weight and needs full back-buttering plus directional troweling. Cut it with the wrong blade and the edge chips. Rectified porcelain tile installation demands tighter tolerances — 1/16” grout joints are possible but only if the substrate is dead flat.
Most porcelain failures we see aren’t cracked tile. They’re hollow tile — spot-bonded instead of full-coverage, releasing from the substrate because the thin-set never made contact across the back.
Porcelain Tile Installation Cost
Porcelain tile installation cost per square foot runs $10–20 installed for standard formats (12×24, 18×18). Large-format slabs (24×48 and up) hit $16–28 — heavier, slower to set, require two-person handling and lippage control on every piece. Wood-look porcelain planks land $12–18 installed.
Labor cost for porcelain tile installation runs higher than ceramic across the board. Harder cuts, mandatory back-buttering, leveling systems, and slower set times. Substrate condition drives the rest — a flat, sound floor is fast; a bathroom with out-of-level subfloor and rotted underlayment doubles the prep. Rainwood Construction quotes after seeing the surface, not from a tile swatch.
OUR TILE SERVICES
What Rainwood Construction covers for porcelain tile installation projects.
Floor Porcelain Tile Installation
Bathrooms, kitchens, entries, living areas. Cement board or uncoupling membrane over subfloor, modified thin-set, tile, grout, seal. Subfloor deflection checked first — L/360 minimum. Porcelain is less forgiving than ceramic on flex: a slight deflection that ceramic survives will crack a porcelain bond. We verify before setting.
Porcelain Wall Tile Installation
Shower walls, tub surrounds, accent walls, fireplace faces. Porcelain wall tile installation on cement board or foam board with waterproof membrane in wet zones. Large-format wall tile needs mechanical support during cure — gravity pulls it before thin-set grabs. We use spacer wedges and support strips on anything over 12”.
Porcelain Plank Tile Installation
Wood-look planks in 8×48 or 6×36. Porcelain plank tile installation follows the same rules as ceramic wood tile — 1/3 offset minimum, back-butter every piece, leveling clips on every row. Difference: porcelain planks are heavier and the cuts are slower. Budget an extra day on a full-floor job.
Outdoor Porcelain Tile Installation
Porcelain’s water absorption under 0.5% makes it frost-proof — ceramic isn’t. Outdoor porcelain tile installation on patios, covered entries, and stairs requires drainage-rated substrate, exterior-grade modified thin-set, and wider grout joints (3/16” minimum) for thermal movement. We slope the substrate 1/4” per foot for drainage.
Porcelain Tile Backsplash Installation
Kitchen and bathroom backsplashes in porcelain subway, mosaic, or large-format. Porcelain tile backsplash installation is cleaner to cut than ceramic — less chipping on a good diamond blade — but harder on the saw. Outlet boxes and window returns need precise notching.

WHY CHOOSE RAINWOOD CONSTRUCTION?
Porcelain punishes shortcuts faster than ceramic. Wrong thin-set, incomplete coverage, no leveling system — the tile looks fine for a month, then starts popping. Rainwood Construction installs porcelain to TCNA and ANSI specs because the material doesn’t forgive anything less.
- Modified thin-set only — full back-butter on every tile over 15”
- Leveling clips on all large-format and plank installations — zero lippage tolerance
- Continuous-rim diamond wet saw for every cut — no scoring, no chipping
- Movement joints per TCNA at every transition and every 8–12 feet of field

Years Experience
Great people. Showed up early and stayed late to get the job done. Work was excellent. Price was the best i found after four quotes. Would definitely use this company again.
We hired Rainwood Construction LLC to replace our French doors, and the result was outstanding. We knew going in this was more involved than a standard swap — we switched from inward to outward swinging doors, requiring extra attention to framing, flashing, and weatherproofing to keep everything sealed against water intrusion.Anatoliy was our point of contact and led the project from before to after, making sure the swing change and weatherproofing were planned and executed correctly. Igor and Vitaly handled the on-site installation and did excellent, high-quality work. The whole team was on time, professional, and delivered top-notch results. Can’t recommend them highly enough. 5 stars!
Every member of this crew I've had the pleasure of coming in contact with has been professional, excellent in their skillset, and fast. Pricing was reasonable for the excellent job they did.Last year we hired Rainwood to do plumbing and painting for a job. Both crews did such a great job, were thorough, and the level of detail was fantastic!We liked them so much we recently hired them for a quick job (installing ceiling fans). We messaged on a Wednesday and the job was done by Friday.Will absolutely hire Rainwood again and again for every job we do for our home.
Working with Rainwood Constructions on our house remodel was an excellent experience from start to finish. Their contractors were highly professional, skilled, and attentive to detail, and the quality of their work exceeded our expectations. The team communicated clearly throughout the project and ensured everything was completed on time without compromising quality. We’re extremely happy with the results and would highly recommend them to anyone planning a home remodel.
We had a very good experience with Rainwood Construction LLC and Toli during my brother’s home construction project in Shoreline. The team was professional, communicative, and paid close attention to detail throughout the process. We were especially happy with the quality of the fittings and finishing work, which turned out really well. The project was handled smoothly, and the overall workmanship met our expectations. Would definitely recommend them to others looking for reliable construction services.
We had an excellent experience with them on our sunroom project. The quality of the work was outstanding, they were easy to work with, and they clearly explained each step, the schedule, and key decisions (with various options to help us understand cost) along the way. Communication was solid from start to finish, and the final result looks great. Highly recommend, they are my new go to recommendation when friends ask.

FAQ
$10–20/sq ft installed for standard formats, $16–28 for large-format slabs, $12–18 for planks. A 75 sq ft bathroom floor in 12×24 with existing backer: $900–1,500. Same room with subfloor repair: $1,800–2,800. Full kitchen in large-format: $5,000–12,000. Substrate condition moves the number more than tile selection.
Porcelain is denser — under 0.5% water absorption vs ceramic’s 3%. That means modified thin-set is mandatory (unmodified won’t bond), every large-format piece needs back-buttering, cuts are slower on diamond blade, and the material is heavier on walls. Same principles, higher execution bar.
Yes — that’s one of porcelain’s advantages over ceramic. Water absorption under 0.5% means freeze-thaw cycles don’t crack it. Outdoor installation needs exterior-rated thin-set, drainage slope in the substrate, and wider grout joints for thermal movement. We install porcelain on covered patios, entries, and stairs across the Seattle area.
Standard bathroom floor: 3–4 working days. Kitchen or living area in large-format: 5–8 days. Large-format porcelain sets slower — back-buttering, leveling clips, and two-person handling on every piece. We schedule cure time between substrate prep and tile, and between tile and grout. No rushing layers.
