Bathroom Renovation in Sammamish
Design-build remodels for the Eastside. One team, one accountability.
Why Sammamish homes deserve a premium remodel
Sammamish plateau homes from the 90s are now hitting the 20-year mark and entering full-renovation territory.
Sammamish's housing stock is largely 1990s–2000s tract homes and luxury plateau builds. We design and build under one roof — functional design in-house, a designer for material selections (ours or yours), and our crew on the build. One team, one accountability, photo-ready handoff.

What's included
Bathrooms have more hidden complexity than they look — waterproofing, ventilation, drain slopes, electrical for heated floors. Design choices made on paper can become problems behind the wall. ERC handles the whole stack in-house: we draft the layout, spec the rough plumbing and mechanical, then build it. Two-phase process: preconstruction (design, engineering, permits) flows into the main construction contract. The crew that sees the drawings is the same crew that swings the hammer. From a guest bath refresh to a 200-square-foot primary suite, you get one team accountable end-to-end.
