Additionally, working on both rooms at once provides an opportunity to create a cohesive design throughout these key spaces in your home. In most cases, a combined kitchen and bathroom remodel in Walnut Creek is the best way to maximize your budget and timeline.

From start to finish, the team was professional, communicative, and very detail-oriented. They took the time to understand what we wanted, offered helpful suggestions, and delivered exactly what they promised. The workmanship was excellent—everything from the tile work to the fixtures was done with care and precision. He showed up on time, kept the work area clean, and completed the project within the agreed timeline. Any questions or small changes were addressed quickly and without hassle. Our new bathroom looks amazing, and we couldn’t be happier with the results. We would absolutely recommend Joseph to anyone looking for quality work and reliable service.

I have been trying to get my bathroom done for almost a year. I had a contract with bathfitters, put down a down payment and after 7 months they were still making excuses on why the haven’t contacted me when they would start. So I concelled my contract with them and got my money back. 3G Builders and Renovation Company was recommended to me so I gave them a call. Joseph came and inspected the damage of the tub and gave me an estimate. We looked over some designs, he ordered the materials needed and once everything was in 4 days later my bathroom was done. I was so pleased and excited. Now my family and I enjoying our new bathroom. Thank you Joseph and crew for an amazing job well done..

Our gallery is filled with real transformations that start with your ideas and end with spaces that feel better to live in every day, from open, inviting kitchens and spa-inspired bathrooms to ADUs, finished garages, basements, and full home renovations. Every project you see reflects a hands-on, client-first process where your goals come first, your questions are always answered, and the details are never rushed. We love creating spaces that feel comfortable, functional, and beautifully finished, so your home feels more like you. Take a look through our work and picture what we can build together.
