Bellevue Basement Bathroom Remodel
Project Transformation: Before & After
Project Overview: A Complete Bellevue Basement Bathroom Transformation
This Bellevue homeowner wanted to transform their unfinished basement space into a fully functional bathroom that would add value to their home and provide convenience for guests and family members. The basement had basic plumbing rough-ins but lacked any finished fixtures, flooring, or design elements. The goal was to create a modern, welcoming bathroom that felt like a natural extension of the home rather than an afterthought.
Our team at Grand Building Construction took on the challenge of working within the basement’s unique constraints — lower ceiling heights, existing plumbing locations, and moisture considerations. We designed a layout that maximized the available space while incorporating a walk-in shower with floor-to-ceiling tile, a stylish single vanity, and durable LVP flooring. The result is a stunning basement bathroom that exceeds the homeowner’s expectations and adds significant value to the property. View more of our transformations in our before and after gallery.

Our Process
Step 1: Consultation & Design
We met with the homeowner to discuss their vision, budget, and timeline. After assessing the basement’s existing plumbing rough-ins and structural layout, we created a design plan that maximized the space while keeping costs competitive.
Step 2: Framing & Rough-In
Our team framed the bathroom walls, installed the shower pan and drain, and completed all plumbing and electrical rough-in work. We also added proper ventilation with a bathroom exhaust fan ducted to the exterior.
Step 3: Waterproofing & Tile Installation
Basement bathrooms require extra attention to moisture management. We applied a waterproof membrane system in the shower area before installing the large-format porcelain tile from floor to ceiling, including the built-in niche.
Step 4: Finishing & Fixtures
We installed the LVP flooring, vanity, countertop, mirror, and all plumbing fixtures. The walls were painted in Sherwin-Williams Endless Sea to create a striking contrast with the light tile.
Step 5: Final Inspection & Walkthrough
After passing all required inspections, we completed a final walkthrough with the homeowner to ensure every detail was perfect and they were fully satisfied with their new basement bathroom.

Bathroom Remodeling FAQs
Do I need a permit for a bathroom remodel in Bellevue, WA?
Permits are typically required when a remodel involves plumbing, electrical, or layout changes. Grand Building Construction coordinates the permitting process and required inspections as part of your project, so everything is built to code.
Can I use my bathroom during a remodel?
During a full bathroom remodel, that bathroom is out of service while work is underway. If your home has a second bathroom, most homeowners stay in the home comfortably; we plan the sequence with you so you know what to expect at each stage.
What affects the cost of a bathroom remodel?
The biggest factors are the size of the bathroom, whether fixtures move or the layout changes, tile and fixture selections, and the condition of the plumbing behind the walls. A free in-home estimate is the most accurate way to price your specific project.
Do you help choose tile, fixtures, and finishes?
Yes. Material selection and planning are part of our process — we help you choose tile, vanities, fixtures, and finishes that fit your home and budget before construction begins.
