A Local Contractor Who Actually Knows SeaTac Bathrooms

SeaTac's housing stock is what shapes every remodel decision here. SeaTac's housing is largely 1950s–1970s construction — modest single-family homes on standard lots, with original kitchens that haven't been touched since the home was built. Angle Lake has a higher concentration of lakefront and view properties where homeowners are investing in larger remodels. Many homes in the airport noise corridor have had window upgrades but original kitchens and baths.

SeaTac is about a 15-minute drive northwest of our Kent location via Highway 99 or I-5. That proximity matters — when materials show up damaged or an inspector needs a same-day correction, we are not driving in from Seattle.

What's Included

Everything Your Bathroom Remodel Needs — Done Right

Bathrooms are unforgiving — water, ventilation, and tight clearances all have to work together. Below is what's typically included in a SeaTac bathroom project; we tailor every estimate to your home.

Tile & Stone

Floor tile, large-format wall tile, custom shower niches, slab walls, and proper substrate (Schluter, cement board) under everything.

Vanities & Cabinetry

Stock, semi-custom, and custom vanities. Wall-mounted, single-sink, and dual-vanity layouts with soft-close hardware.

Plumbing

Toilet, sink, shower valve, and tub installation. Relocating drains, replacing old galvanized supply lines, and rough-in for new fixtures.

Fixtures

Faucets, showerheads, body sprays, handheld wands, tub fillers, towel bars, and hardware — coordinated with your aesthetic.

Lighting

Vanity sconces, recessed lighting, decorative pendants, and dimmer-friendly switching. Always to code, always GFCI-protected.

Waterproofing

Schluter Kerdi, Wedi, or hot-mopped pans. Proper waterproofing under tile is the difference between a 5-year and 30-year bathroom.

Ventilation

Exhaust fans sized for the room, vented to the exterior (not the attic), with humidity-sensing controls when requested.

Glass & Doors

Frameless shower glass, custom hinged or sliding panels, and barn-door hardware. Measured and templated after the tile is set.

Permits & Inspections

We pull City of SeaTac permits when plumbing or electrical work is involved, and we schedule the rough-in and final inspections.

SeaTac Permits & Considerations

What to Know Before You Start

The City of SeaTac requires a building permit any time a bathroom remodel involves plumbing relocation, electrical changes, or structural alterations. A like-for-like fixture swap (same toilet location, same vanity footprint) often doesn't require a permit — but moving a shower drain, adding a circuit, or changing the layout always does.

We pull every required permit through the SeaTac Permit Center, coordinate the rough-in and final inspections, and keep documentation in your project file. Bathroom permits matter especially at resale, since inspectors and appraisers flag undocumented work.

  • Permits filed with the City of SeaTac under our license, not yours
  • Rough-in and final inspections scheduled and met on-site
  • SeaTac requires specific noise-attenuation considerations on additions in certain airport-impact zones — we know the boundaries
  • Permit copies handed to you at close-out for resale records
