CRBA remodels bathrooms across Hayward, Castro Valley, San Leandro, Fremont, and the greater Bay Area — for homeowners converting an unused tub into a walk-in shower, updating a 1970s hall bath that’s never been touched, building a primary suite bathroom worth waking up to, or adapting a bathroom for aging parents. One licensed team handles design, demolition, plumbing, electrical, tile, and finish work — with waterproofing done right behind the walls, permits pulled by us, and a written quote before a single tile comes off. Licensed general contractor since 2015, 200+ Bay Area homes completed. Lic #1095283.

Talk to the contractor, not a call center.
Bathrooms fail quietly. By the time you see the problem on the surface, the real damage is usually behind the tile. Here’s what Bay Area homeowners tell us right before a remodel — if two or more sound familiar, it’s time:
Recognize your bathroom? Call (510) 990-9243 and tell us what you’re seeing. We’ll tell you honestly whether it’s a repair, a partial update, or a full remodel — and roughly what each looks like — before you commit to anything.
Six ways we remodel bathrooms, each for a different home and household.
Down-to-the-studs transformations: demolition, layout changes, plumbing and electrical, waterproofing, tile, vanity, lighting, and finish work — managed start to finish by one licensed team. This is the fix for bathrooms where everything is original and nothing is worth saving. Most full hall-bath remodels run 3–5 weeks; primary baths 4–8 weeks depending on scope.
Our most-requested bathroom project. We remove the tub, rebuild the wet area with proper waterproofing (the part that decides whether your shower lasts 30 years or leaks in 3), and install a walk-in shower with tile, glass, and fixtures matched to your home. Standard, low-threshold, and fully curbless options.
Oversized walk-in showers, rainfall and multi-head systems, frameless glass, heated floors, and freestanding tubs — the primary-suite bathroom done properly. We handle the plumbing capacity questions (yes, your water heater matters) as part of design, not as a surprise later.
Small bathrooms punch above their weight — a dated powder room drags down a whole floor, and a well-designed one is the cheapest “wow” in the house. We remodel half baths and compact full baths with space-smart vanities, pocket doors where framing allows, and storage that doesn’t crowd the room.
Curbless showers, fold-down benches, grab bars anchored into blocking (not drywall), comfort-height toilets, slip-resistant tile, and wider clearances — designed to look like a beautiful bathroom, not a hospital room. For aging in place, multigenerational homes, and wheelchair access across the Bay Area.
Shower surrounds, floor tile, accent walls, and backsplashes installed with level lines and waterproof backing — plus vanities, countertops, mirrors, and lighting. For bathrooms where the bones are good and the finishes are the project.
Don’t see your project? Call (510) 990-9243— we handle it all.
Call (510) 990-9243 and talk to Ray or the project team — not a salesperson. We ask what’s driving the remodel, what’s staying and going, and your rough budget comfort. From that call we can usually tell you what’s realistic and what it roughly costs.
We come out free of charge, measure, check what’s behind the walls where possible, and talk through layout, materials, and options at your actual budget. You get a written, itemized quote — demolition, trades, materials, permits, timeline — before anything is scheduled. Design help included; we’ve done 200+ of these and we’ll tell you what works.
We pull the permits, protect your home with floor and dust protection, and run the job with our own crew — demo, rough plumbing and electrical, city inspections, waterproofing, tile, fixtures, finish. You get progress updates, one point of contact, and a final walkthrough where everything works and everything’s clean before we call it done.
Realistic Bay Area ranges: a finish-level refresh of a hall bath typically runs ($15,000–$30,000),
a full mid-range remodel ($35,000–$70,000),
a custom primary/spa bathroom ($70,000–$150,000+).
Your written quote covers your actual project.
What you won’t pay for:
Call (510) 990-9243 with your bathroom size and wish list — you’ll have a working range before you hang up.
Phone range first. Tell us the bathroom size, what’s moving, and finish level, and we’ll give you a working range on the call — no visit required for a ballpark.
Free in-home estimate before any work. We measure, assess, and write the quote down — itemized. No estimate fee, no obligation.

In 2026, most Bay Area bathroom remodels run $[35,000–$70,000] for a full mid-range remodel of a standard hall bath, with finish-level refreshes starting around $[15,000] and custom primary bathrooms reaching $[100,000+]. The biggest cost drivers are whether plumbing fixtures move, the wet-area scope, and finish tier. CRBA provides a written, itemized quote after a free in-home visit
A typical full bathroom remodel takes 3–5 weeks from demolition to final walkthrough; small or finish-only projects run 2–3 weeks, and large primary-suite bathrooms 4–8 weeks. Permit approval in Hayward and most Bay Area cities adds 1–4 weeks before work starts, which we build into the schedule.
Yes, in nearly all cases. Any bathroom remodel involving plumbing, electrical, or structural changes requires permits in Hayward and throughout Alameda County — and unpermitted bathroom work is a common home-sale problem. CRBA pulls all permits and schedules inspections as part of every project.
Yes — tub-to-shower conversions are our most requested bathroom project. Most conversions take 1–2 weeks and include full waterproofing of the new wet area, tile, glass, and fixtures. Curbless (zero-threshold) options are available for accessibility or a modern look.
Yes — small bathrooms deliver some of the strongest returns per dollar in a remodel. A dated powder room affects every guest's impression of the home, and space-smart design (compact vanities, pocket doors, wall-mounted fixtures, better lighting) can make a small bathroom feel dramatically larger without moving walls.
In our Bay Area projects: walk-in showers with frameless glass, double vanities, heated tile floors, and dedicated storage. Tub-to-shower conversions lead by volume — most households keep one tub in the house (usually the hall bath) and convert the rest.
Keep at least one tub in the house if you can — families with young children still look for it. But converting a second or primary bathroom tub to a walk-in shower generally helps rather than hurts Bay Area resale, where buyers increasingly prefer large showers in the primary suite.
Yes — that's the entire point of modern aging-in-place design. Curbless showers read as high-end contemporary design, grab bars now come in finishes matching your fixtures, and comfort-height toilets are indistinguishable from standard ones. We design accessible bathrooms across Hayward, San Leandro, and the Bay Area that guests read as "beautiful," not "medical."
Yes, we work with financing partners for qualified homeowners — ask during your estimate and we'll walk you through options. [If no:] We don't offer in-house financing, but we structure payment schedules by project milestone, so you're never paying for work that hasn't happened.

Posted on Google Ravi NukalaTrustindex verifies that the original source of the review is Google. We had a great experience working with Ray and his team on our home addition. They helped us add close to 650 sq. ft., and the entire project was completed in less than four months from start to finish, which was impressive. Ray and his team were professional, responsive, and easy to work with throughout the project. They kept things moving efficiently and worked closely with us through each stage. We’re very happy with the outcome and truly appreciate the effort and commitment from the entire team. Highly recommend Ray and his team for anyone considering a home addition or renovation!Posted on Google John MaraisTrustindex verifies that the original source of the review is Google. Ray turned our outdated kitchen into a beautiful new space. He was professional, easy to work with, and delivered excellent craftsmanship. We're thrilled with the results and highly recommend Construction Remodeling In Bay Area.Posted on Google Danial StalcupTrustindex verifies that the original source of the review is Google. We had our master and second bathrooms remodeled by Ray and his team. Our foreman was Alex. We had the rooms stripped down to the studs. New floor, new drywall, new electric, new bathtub and shower, new wall tiles, and all the furnishings. We provided detailed plans, layouts, and furnishings list. Overall we are very happy with the result. Alex was very detail oriented, and was always ready to make a change if something wasn't going to work for us. His drywall, paint, and trim work were excellent. Tile work was very good as well. He and his team were very respectful of our space and did their best to keep things clean (but any remodel makes a mess!) Ray was very responsive to my questions and was easy to get a hold of. Always friendly and easy going. At the end of the project our bathrooms were complete all the way down to the details I laid out in a plan. The value for their work is excellent - we had another contractor bid 50% more and I seriously doubt they could do 50% better! Did everything go perfect? No... do I think it would have gone better with another company? Nope! However, when there are problems the most I can ask for is solutions, and Ray and Alex worked with us to solve them. Also the timeline of the work went longer than expected. This may have been mitigated by more workers on some days, but sometimes you can't rush good work.Posted on Google David SeronTrustindex verifies that the original source of the review is Google.

Great crew with true profesionales!Posted on Google Xiaodi CuiTrustindex verifies that the original source of the review is Google. I can’t say enough good things about Ray and his crew for my kitchen and two bathrooms remodel. Under Nino’s leadership, the team showed up every day for six weeks and finished right on schedule. Nino was on-site daily, guiding the crew with skill and care, and Ray stopped by weekly to check quality control and personally ensure I was completely satisfied. They went above and beyond by relocating my kitchen sink and dishwasher to create a much better layout, and they also moved the master bathroom plumbings to improve that space as well. Furthermore, they replaced my subpanel because the old breakers has become obsolete. The results are great—my kitchen and bathrooms look absolutely beautiful. Without a doubt, I will hire Ray for any future projects.Posted on Google Markus ClaassenTrustindex verifies that the original source of the review is Google.

Ray and his team recently remodeled our bathroom. From the start to finish it was a great experience. Ray was available throughout the design appointment and helped us make the right selections. His crew worked every single day and sometimes on weekends too if things took longer than planned. They were happy to redo or accommodate our changes as needed. His crew works really hard and ensures that you are happy with the outcome. We highly recommend him and would definitely work with him again.Posted on Google Andrew RiscoeTrustindex verifies that the original source of the review is Google.
