A Local Contractor Who Actually Knows Newcastle Bathrooms

Newcastle's housing stock is what shapes every remodel decision here. Newcastle is a small, hilly city tucked between Bellevue and Renton. Most homes are 1980s–2000s construction in view-oriented subdivisions like Olympus and the developments around Lake Boren, often built on steep terrain that affects access for material delivery and demo. A handful of older 1950s–60s homes remain near the original China Creek mining area.

Newcastle is about a 25-minute drive northeast of our Kent location via I-405. 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 Newcastle 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 Newcastle permits when plumbing or electrical work is involved, and we schedule the rough-in and final inspections.

Newcastle Permits & Considerations

What to Know Before You Start

The City of Newcastle 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 Newcastle 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 Newcastle under our license, not yours
  • Rough-in and final inspections scheduled and met on-site
  • Newcastle contracts plan review with King County — we know that workflow
  • Most Newcastle subdivisions have HOAs with view-protection and exterior requirements we work within
  • Permit copies handed to you at close-out for resale records
