What We Do
Complete Bathroom Remodeling Services
From concept to completion, we handle every aspect of your bathroom remodel — so you get the bathroom you've always wanted without the stress.
Walk-In Showers & Tub-to-Shower Conversions
Frameless glass enclosures, curbless walk-in showers, rain heads, body jets, and built-in niches. We also convert outdated tubs into spacious, accessible showers — all with expert waterproofing that prevents leaks for decades.
Custom Vanities & Countertops
Single or double vanities in every style — floating, freestanding, or built-in. Quartz, marble, and granite countertops with undermount sinks, soft-close drawers, and custom storage solutions designed for your space.
Tile & Stone Work
Floor-to-ceiling tile, mosaic accents, large-format porcelain, natural stone, and patterned encaustic tile. Precision installation with proper substrate prep and waterproof membranes behind every wet surface.
Lighting & Electrical
Layered lighting design with vanity sconces, recessed ceiling lights, backlit mirrors, and dimmer controls. GFCI outlet upgrades, exhaust fan installation, and full electrical work to meet Seattle code.
Plumbing & Fixtures
Fixture relocations, new supply lines, drain rerouting, and tankless water heater connections. We install every faucet, showerhead, toilet, and valve — and handle all plumbing behind the walls.
Accessibility & Aging-in-Place
Grab bars, curbless showers, comfort-height toilets, handheld showerheads, wider doorways, and non-slip flooring. We design bathrooms that are safe and beautiful for every stage of life.

The Giant Builders Difference

What Our Clients Say
Hear from Seattle homeowners who built their dream bathroom with us.
“I had three contractors bid on my Queen Anne master bathroom. Giant Builders wasn't the cheapest, but they were the most detailed — their estimate line-itemed everything from tile adhesive to the shower valve. No surprises during the build. The heated floors and frameless glass shower turned out beautifully.”
“We wanted to convert our old tub into a walk-in shower with a built-in bench. Giant Builders handled the waterproofing, tile work, and glass enclosure — it looks like something out of a design magazine. The crew was respectful and cleaned up every day.”
“Our 1960s bathroom needed everything — new plumbing, electrical, tile, vanity, and a complete layout change. Giant Builders managed the whole project and finished on schedule. The 3D renderings were spot-on. We use the soaking tub every night now.”
