The Bathroom Remodel Challenge

The original bathroom had water damage behind the shower walls. Once the damaged assembly was opened, the remodel became more technical than a standard finish update. The shower area needed proper waterproofing, flat surfaces for oversized porcelain tile, careful work around the window, and a correctly sloped shower floor.

The homeowners stayed in the house during construction, so dust control, cleanup, and schedule coordination mattered. This was not a simple cosmetic job; it was a rebuild focused on durability.

Homeowner Goals

The clients wanted a calm, modern bathroom that was easier to maintain. Their ideas centered on a spa-like shower, stronger moisture protection, a double vanity, and durable finishes.

The Solution

Iconiq Construction completed the bathroom remodel from demolition through final detailing. The company’s designers helped refine the homeowners’ vision, select materials, and plan the layout, while the construction team rebuilt the shower with a waterproof membrane system, cement backer board, modified thin-set mortar, premium grout, and silicone expansion joints.

Large-format porcelain wall tile reduced grout lines, while the mosaic shower floor added texture and traction. A recessed niche, glass enclosure, and quartz double vanity completed the design.

Our Process

The process covered inspection, demolition, waterproofing preparation, tile layout planning, installation, cabinetry, countertop work, glass installation, cleanup, and a final walkthrough. Much of the critical work happened behind the finished surfaces, including waterproofing, substrate preparation, and careful coordination around the shower window.

Project Timeline

This project took approximately 3–4 weeks. More broadly, bathroom remodels often take 4–6 weeks, although timing varies by scope. Design planning can take 2–4 weeks before construction begins, while material lead times, inspections, permitting, and unexpected repairs may extend the schedule.

Before and After

Before, the bathroom had failed waterproofing and outdated finishes. After the remodel, it had a stronger shower system, cleaner layout, quartz vanity, and premium tile work. The finished space is brighter, easier to maintain, and better protected from moisture.

Local Context

In the greater Seattle area, moisture control is especially important in bathrooms and other wet spaces. Durable materials, proper waterproofing, and effective ventilation help manage humidity, while careful detailing around showers, niches, windows, and floor transitions reduces the risk of repeat moisture problems.

FAQs

This project took about 3–4 weeks. Larger renovations can take longer depending on material lead times, inspections, permitting, and unexpected repairs.

Yes, many clients choose a shower-focused layout, but the design depends on plumbing, space, budget, and the existing bathroom structure.

Start with a clear scope, choose durable materials, and keep a contingency for hidden issues. A good contractor will explain any additional costs before extra work moves forward.
