Bathroom Remodel Seattle (Expanded Shower)

Bathroom Remodeling FAQs

Do I need a permit for a bathroom remodel in Seattle, 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.

Had a nasty looking tub and surround.  Got an acrylic wider tub and surround installed, they did the job in about 1.5 days, got a great price on the job.  Left the area good and clean, no damage to anything.  I would use them again.

We hired a contractor in May to remodel our kitchen. He promised the project would be completed in three weeks. Unfortunately, after a month, less than 40% of the work had been completed. He disappeared several times without notice, and our calls and messages often went unanswered. Eventually, we decided to hire another contractor to finish the job. We are incredibly grateful that we found Grand Building Construction. Joshua and his team, Wei and Ken, completed the remaining 60% of our kitchen remodel in just five days. They ordered and installed the countertops and backsplash, corrected the mistakes left by the previous contractor, installed the flooring, completed the painting, and finished the lighting installation. Joshua, Wei, and Ken were hardworking, detail-oriented, professional, and communicative throughout the entire process. They kept us informed every step of the way, and their craftsmanship and dedication exceeded our expectations. They turned what had become a stressful and frustrating experience into a beautiful, finished kitchen that we absolutely love. We truly appreciate everything Joshua and his team did for us. Thanks to Grand Building Construction, we finally have our dream kitchen. We highly recommend them to anyone looking for a reliable, skilled, honest, and trustworthy contractor.

I recently had my master bathroom remodeled by Grand Building Construction, and I couldn’t be happier with the results. They helped us transform a dated, inefficient space with a bulky corner tub into a modern, spa-like walk-in shower. I came into this project with a very clear, specific vision of what I wanted, and the team was incredible to work with. They were remarkably flexible and genuinely amenable to my ideas, working closely with me to ensure every detail aligned with the final look I had in mind. Beyond their design flexibility, I was truly impressed by their technical expertise—particularly the care they took with the plumbing rerouting and the advanced waterproofing systems. They kept the project moving efficiently, finishing everything on schedule in just one week. The quality of the finished space—from the precise large-format tile work to the installation of the matte black fixtures—is outstanding. If you’re looking for a professional, collaborative team in the Renton area that listens to your vision and executes it to a high standard, I highly recommend Grand Building Construction.

Josh, Wei, Ken and team did a great job on my kitchen remodel. They were very communicative, had fair prices, and were detail oriented. We were able to work together to make our kitchen goals happen. I would not hesitate to hire them again for another construction project! Thank you!

This review is far overdue. We worked with Emil to renovate our two bathrooms, kitchen, relevel a sunken living room floor, create a pantry, and a few other things for my house Kirkland. Emil and his team provided quality work. Grand Building I has a lot of experience and guided us new homeowners through our extensive renovation. The team was punctual and extremely professional. They always cleaned up at the end of the workday. We would work with them again in the future.

I recently hired Grand Building Construction for a kitchen remodeling and I couldn’t be happier. The quality of the workmanship is outstanding, and the team showed great integrity by staying honest about timelines and costs. Communication was clear and frequent, so I always knew what was happening. They arrived on time every day (often working 6 or 7 days a week) and finished the project within the budget, which made the price feel very fair. I especially appreciated how they respected my home and kept the work area clean. Josh and the team were open and communicated frequently throughout, always finding a way to incorporate our design choices. I would definitely work with GBC again and am recommending them to anyone i know looking to do a renovation.

I recently decided to remodel my master bathroom because it was seriously outdated,  since the 70s! Working with Emil so far has been a pleasure. We got creative together, figuring out solutions for things that mattered to me. His communication and attention to detail were what I really liked. From the beginning of the project, Emil made sure I was in the loop and part of every decision making process. I really appreciated that, especially since I can be quite picky about what I want. The bathroom is still in progress but so far I absolutely love the transformation! Thank you guys! I must say the work has been on time, super clean, the crew is very respectful and I appreciate their hard work. We're still in the process right now and so far this is my 5 star review.

Josh helped us turn our old tub into a modern walk in shower, and it completely changed the feel of our bathroom. He suggested a tile pattern I never would have thought of, and it looks incredible with the lighting. Every evening before leaving, he cleaned up so well you could barely tell work was being done. The water pressure feels stronger now and the glass enclosure makes the whole room brighter. Couldn’t be happier with how it came out.

I had them convert my tub into a walk-in shower, and it’s easily the best upgrade I’ve done. The tile work is stunning, and the glass enclosure makes the whole bathroom feel bigger. They even added a rainfall showerhead — total game changer.

Grand Building Construction in Bellevue did our bathroom remodel after years of putting it off, and I wish we had done it sooner. The crew removed old flooring, updated the plumbing, and created a gorgeous walk-in shower with glass doors. They also added a double vanity that makes mornings so much easier. The project was seamless, and their communication made the whole process stress-free. Our new bathroom is both practical and stunning.
