Bathroom Remodeling FAQ — Seattle Area
Common questions homeowners ask before starting a bathroom remodel. Answers based on Washington code, Seattle city rules, and real project experience.
Do I need a permit for a bathroom remodel?
Permits are required when modifying plumbing, electrical, ventilation, framing, or layout. Cosmetic updates typically do not. We handle all city permit applications and inspections if needed.
How long does a bathroom remodel take?
Small bathrooms take 10–15 working days. Standard bathrooms take 3–4 weeks. Primary or luxury bathrooms with custom tile and glass may take 4–6+ weeks.
Do you use certified waterproofing systems?
Yes. We use Schluter Kerdi, Wedi, and Hydro Ban waterproofing systems. Every shower includes full membrane coverage and proper substrate preparation.
Can you expand or relocate the shower?
Yes. We can enlarge the shower, move the drain, relocate plumbing lines, and adjust framing. This is common in older Seattle homes where layouts are outdated.
Do you install heated floors?
Yes. Electric heated floors work very well in Washington’s climate. We install systems compatible with tile and provide smart thermostat options.
Do you handle plumbing and electrical upgrades?
Yes. We upgrade outdated plumbing and electrical to meet current Washington state code, including GFCI outlets, new circuits, LED lighting, and proper shutoff valves.
Can you remodel condo bathrooms?
Yes. We handle HOA approvals, work-hour restrictions, material delivery rules, and elevator scheduling required in many Seattle condo buildings.
Do you offer fixed-price contracts?
Yes. Every bathroom remodel includes a clear scope with a fixed price. Only changes in scope require a written change order.
Do you perform flood testing on shower pans?
Yes. We seal the drain, fill the shower base with water for 24 hours, and verify the waterproofing system before tile installation. Required for many inspections.
What type of backer board do you use behind tile?
We use cement board, Schluter Kerdi-Board, or Wedi foam board — all moisture-resistant and compatible with modern waterproofing systems for long-term durability.
Can you install a curbless or linear-drain shower?
Yes. Curbless showers require subfloor modification and precise slope engineering. Linear drains work well for modern tile layouts and large-format tile.
How do you ventilate high-moisture bathrooms?
We install exhaust fans vented directly outdoors, not into the attic. Proper ventilation prevents mold and meets Washington building code.
Do you replace older galvanized plumbing?
Yes. Galvanized lines are often corroded and should be replaced with PEX or copper during a remodel to ensure good pressure and reliability.
What tile types perform best in Washington homes?
Porcelain tile is the most durable and moisture resistant. Natural stone is possible but requires sealing and regular maintenance.
