Fast, Reliable Bathroom Remodeling Across San Lorenzo
A full bathroom remodel in San Lorenzo typically runs $9,000 – $28,000 and takes two to four weeks, depending on whether the original 1940s subfloor and mudsill need replacement. Call (949) 850-9896 to schedule your free estimate and written price before any work starts.
We serve San Lorenzo from our San Francisco Bay Area dispatch office, with crews who know the Bohannon tract blocks by heart. These near-identical post-WWII homes built between 1944 and 1954 repeat the same floor plans, the same cripple wall heights, and the same moisture problems from decades of fog sitting low over the flatland near San Lorenzo Creek. That predictability helps us bid accurately, but it also means we come prepared for the rot that hides behind every other tub surround in this community.
Our Bathroom Remodeling team works with families who have kids and pets, so we lay drop cloths at every doorway, wear shoe covers inside, and run quiet tools during nap hours where the schedule allows. We ask before moving furniture, and we photograph the clean-up before we leave so you see exactly how we left the space.
Why Elmstead Remodeling Is San Lorenzo’s Preferred Bathroom Remodeling Company
San Lorenzo homeowners call us back because we name what will break before we open the wall. The 365-Day Done Right Promise covers every completed project, stamped on the contract. If it’s not done right, we make it right.
Our written price comes before any work starts, every time. No estimate that grows after the crew arrives. Background-checked, uniformed technicians walk through your door, and a live person answers the phone 24/7, not a voicemail box.
We know these houses. The Bohannon tracts near Hesperian Boulevard, the blocks off Lewelling Boulevard, the homes tucked behind San Lorenzo Creek’s flood plain, each carries the same 2x mudsill, the same shallow crawlspace, the same moisture wicking up from the flatland soil. We’ve sistered rotted rim joists on Washington Avenue, bolted cripple walls on Fargo Avenue, and installed Cambria quartz and KraftMaid vanities in bathrooms from one end of San Lorenzo to the other.
Styles & brands we work with
One Day Bath Remodel in San Lorenzo
One Day Bath Remodel in San Lorenzo is a surface-level refresh that replaces the tub or shower surround, updates fixtures, and installs a new vanity and toilet without moving walls or plumbing locations. A San Lorenzo homeowner needs this when the Bohannon-era bathroom is dated but the subfloor tests solid and the layout already works. This scope typically costs $5,000 – $12,000 for a small bathroom, or up to $15,000 if you’re adding a walk-in shower kit with frameless glass.
We see this most often in the Bohannon tracts where the family wants to stay in the house during work, where kids need the bathroom functional each evening, and where the hidden framing is still sound. Our crew arrives with shoe covers, lays drop cloths across the hallway and bedroom path, and works within a single contained zone.
What Stays and What Goes
The toilet, vanity, and tub or shower stay in their original positions. We remove the old surround, repair any surface wall damage, install a new acrylic or tile system, set a new Kohler or Moen fixture package, and leave the bathroom fully operational by evening. No permit required for this scope in San Lorenzo if plumbing lines are not relocated.
When the One-Day Scope Isn’t Enough
If we open the wall and find the mudsill rotted from creek-adjacent moisture, we stop, photograph the damage, and present a revised written price before continuing. Most San Lorenzo homeowners appreciate this pause. Nobody wants to discover rot after the tile is already ordered.
Bathroom Remodeling Contractor in San Lorenzo
Bathroom Remodeling Contractor in San Lorenzo means a licensed general contractor who pulls permits, coordinates inspections, and manages the full scope from demolition through final walk-through. A San Lorenzo homeowner needs this when moving walls, replacing the subfloor, converting a tub to a walk-in shower, or any job that touches structural framing or plumbing rough-in. Full bathroom remodels in San Lorenzo run $9,000 – $28,000, with most Bohannon tract projects landing in the $14,000 – $22,000 range once hidden rot is addressed.
We pull permits through Alameda County for any job that moves plumbing, alters electrical, or replaces subfloor framing. Our crews pass inspection on rough plumbing, electrical, and final finish. The 365-Day Done Right Promise covers every completed project.
Seismic and Structural Coordination
Because San Lorenzo sits near the Hayward Fault, we bolt cripple walls and sister pressure-treated mudsills whenever we expose them during bathroom demo. This isn’t an upsell. It’s the condition we find, and the correction that protects the bathroom investment from the earthquake every Bay Area homeowner knows is coming.
Material Selection for the Coastal Flatland
We specify Schluter waterproofing membranes behind tile in San Lorenzo bathrooms because the fog-driven dampness here never fully dries the exterior walls. Standard paper-and-wire lath fails early in this microclimate. We also vent bathroom fans directly through the roof, never into the attic, because we’ve seen too many San Lorenzo ceiling structures rot from condensation.
Trusted Brands We Service in San Lorenzo
We install cabinets from KraftMaid and Wellborn, countertops from Cambria, Silestone, and Caesarstone, and fixtures from Kohler, Moen, and Grohe. These are brands you can research independently, with manufacturer warranties that travel with your home. We stock common Kohler valve cartridges and Moen trim kits locally, so if a San Lorenzo homeowner calls with a warranty concern six months after completion, we can often resolve it without a two-week parts wait. For exterior work on additions or ADUs, we specify James Hardie siding and GAF roofing. We also work with Sakrete for concrete and masonry needs when bathroom expansions require new foundation or patio demolition.

AfterCommon Bathroom Remodeling Problems We See in San Lorenzo Homes
- Rotted mudsill and subfloor rim joists behind the tub. Decades of ground moisture wicking up through the Bohannon crawlspace softens the original 2x framing. We sister pressure-treated lumber and bolt the cripple wall before setting new fixtures.
- Bathroom fans vented into the attic instead of through the roof. The fog that sits over San Lorenzo’s flatland condenses in attic framing and rots ceiling joists above the bathroom. We run proper roof vents with insulated ducting.
- Tile laid over subfloors too flexible for the original 2x joist spacing. Bohannon homes used 16-inch or wider centers with minimal blocking. Without added plywood underlayment or sistered joists, grout cracks within two seasons. We engineer the subfloor before tile goes down.
- Outdated electrical panels that can’t handle modern GFCI requirements. Many San Lorenzo bathrooms still run on ungrounded circuits. We coordinate licensed electrical upgrades as part of the remodel scope, permitted and inspected.
Pricing for Bathroom Remodeling in San Lorenzo, CA
Here is what bathroom work costs in the San Lorenzo market, based on the Bohannon tract conditions we encounter regularly:
| Service | Price Range in San Lorenzo |
|---|---|
| Bathroom Remodel | $9,000 – $28,000 |
| Small Bathroom Remodel | $5,000 – $12,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
| Tub-to-Shower Conversion | $3,500 – $10,000 |
| Shower Replacement | $3,000 – $8,500 |
| Bathroom Vanity Installation | $800 – $3,000 |
The gap between a $9,000 and a $28,000 bathroom in San Lorenzo usually comes down to three factors: whether the mudsill and subfloor need replacement, whether you’re moving plumbing locations, and whether you’re expanding into an adjacent closet or bedroom. Coastal-spec materials, stainless hardware, and Schluter waterproofing add 10 – 15% upfront but prevent the callbacks we see on jobs that used inland-grade specs. A cheap exhaust fan or unsealed grout joint costs more within five years in this fog-driven climate.

FAQs About Bathroom Remodeling in San Lorenzo
San Lorenzo’s Bohannon tract homes almost always need subfloor and mudsill repair from decades of creek-adjacent moisture, plus seismic bolting that Castro Valley or Union City split-levels don’t require. The $9,000 – $28,000 range accounts for this structural work. Call (949) 850-9896 for an exact quote on your specific house.
Yes, if you’re moving plumbing, altering electrical, or replacing subfloor framing. Alameda County requires permits for rough plumbing and electrical, and we pull them on every job that qualifies. Surface replacements with no plumbing relocation typically don’t need permitting. We’ll tell you which category your project falls into during the free estimate.
We stop work, photograph the damage, and present a revised written price before proceeding. Because the Bohannon homes repeat the same floor plan, we carry pressure-treated lumber and seismic hardware on every San Lorenzo job so we’re ready. The homeowner on Fargo Avenue told us the same rot pattern showed up on three other houses on the street. They’re the same house.
Keeping the toilet, vanity, and tub in their original locations typically saves $2,000 – $4,000 in San Lorenzo because we avoid rerouting drain lines through the old cripple wall framing. If the current layout doesn’t function for your family, moving plumbing is absolutely doable, and we’ll price both options in your written estimate.
We regularly install KraftMaid and Wellborn cabinets, Cambria and Silestone countertops, and Kohler, Moen, and Grohe fixtures. You may supply your own materials, though we warranty our installation work only, not homeowner-supplied products. Manufacturer warranties from our partner brands travel with the finished project and are verifiable independent of us. Call (949) 850-9896 to discuss your preferences.
