Bathroom Renovation in Issaquah
Design-build remodels for the Eastside. One team, one accountability.
Why Issaquah homes deserve a premium remodel
Newer Issaquah homes are reaching the age where finishes and layouts date faster than the structure does.
Issaquah's housing stock is largely largely 1990s and 2000s construction, with older pockets near the lake and downtown. 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. That includes stand-alone shower remodels and tub-to-shower conversions — the single most requested bathroom renovation on the Eastside — where we re-frame the opening, rebuild the pan and waterproofing, and finish the tile without subbing the work out.
