A Local Contractor Who Actually Knows Renton Bathrooms

Renton's housing stock is what shapes every remodel decision here. Renton has some of the oldest housing stock in South King County. The Renton Highlands and Earlington areas are full of original Craftsman bungalows and 1940s–50s post-war homes — beautiful bones but often with knob-and-tube wiring still hiding behind walls, cast-iron drain stacks, and lath-and-plaster surfaces that need careful demo. Kennydale and Talbot Hill mix mid-century homes with newer infill construction.

Our Kent base is about a 15–20 minute drive north on Highway 167, putting Renton site visits and material runs squarely in our daily route. 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 Renton 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 Renton permits when plumbing or electrical work is involved, and we schedule the rough-in and final inspections.

Renton Permits & Considerations

What to Know Before You Start

The City of Renton 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 Renton 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 Renton under our license, not yours
  • Rough-in and final inspections scheduled and met on-site
  • Renton requires a separate plumbing permit for fixture relocations, which we handle as part of every kitchen or bath remodel
  • Permit copies handed to you at close-out for resale records
