Bathroom Remodeling in Concord, CA
Custom designs, licensed crews, and fast quotes — from tub-to-shower conversions to full master suite renovations across the East Bay.
The damage only whispers until it speaks up
The grout keeps darkening no matter how hard you scrub. The floor near the toilet gives a little when you step on it. There is a stain on the ceiling below, and the last guy told you it was condensation. It was not condensation. Water has been moving through the wall cavity for years, and every month you wait adds to the repair bill.
Bathrooms hide more damage than any other room in a house. Legend Remodeling & Improvement opens the walls, shows you what is actually back there, and rebuilds the room correctly from the framing out. We work out of Concord, and we handle bathroom remodel projects across the East Bay.

What Does Bathroom Remodeling Include?
A full bathroom remodel includes demolition, plumbing and electrical updates, framing repairs, waterproofing, tile installation, and new fixtures. Legend Remodeling & Improvement in Concord, CA handles tub-to-shower conversions, walk-in showers, vanities, flooring, lighting, ventilation, and aging-in-place upgrades under one written contract.
We repair hidden water damage and dry rot before finish work begins, and we pull the permits your project requires. Most Concord bathroom remodels take three to five weeks and cost between $15,000 and $40,000.
We answer seven days a week, 6 AM to 11 PM, and your estimate costs nothing.


Why Choose Us
Most bathroom remodel contractors compete on tile selection. We compete on what goes behind it.
We waterproof properly every time
Tile is not waterproof, and neither is grout. Water passes through both. A correct shower needs a continuous waterproofing membrane, a pre-sloped pan, and sealed corners and penetrations. We use bonded sheet membranes and liquid-applied systems, never green drywall behind tile.
We repair what we find
Rotten subfloor, corroded galvanized supply lines, damaged framing around the tub, and rusted drain assemblies are common in homes built before 1980. We photograph the condition, price the repair as a written change order, and wait for your approval before continuing.
We are licensed, bonded, and insured
Verify our record with the California Contractors State License Board. We carry general liability and workers' compensation coverage, so a job-site injury never touches your homeowners policy.
We handle permits
Moving a toilet, relocating a shower drain, or adding circuits requires a permit in Concord. Unpermitted bathroom work surfaces during escrow and costs the sellers real money. We file, schedule inspections, and hand you the signed final card.
We keep your household functional
We install dust barriers, protect flooring on the path to the work area, and coordinate the schedule so you keep a working bathroom whenever the layout allows.
We price in line items
Tile, vanity, labor, plumbing fixtures, permit fees, and disposal appear as separate lines. You can see exactly where your money goes and adjust before we order anything.
We stand behind the work. Our written workmanship warranty covers our installation, and manufacturer warranties cover the fixtures and materials we specify.
Our Process and Service Details
Bath renovation runs on sequence. Rough plumbing has to pass inspection before insulation. Waterproofing has to cure before tile. Skipping steps to save a week is how bathrooms fail in year three.
Free In-Home Consultation
We measure the room, inspect the existing plumbing and venting, check the subfloor for soft spots, and look at the ceiling below for staining. Then we talk through what you want and what your budget realistically supports.
Design and Fixture Selection
We lay out the room around plumbing realities and clearance requirements. California code requires at least 15 inches from the toilet centerline to any side wall or fixture and 24 inches of clear space in front. Showers need a minimum interior footprint. These numbers shape every layout, and knowing them early prevents expensive redesigns.
Written Estimate and Contract
Itemized scope, line-item pricing, payment milestones tied to progress, and a construction schedule. No obligation.
Permits and Material Ordering
We file with the City of Concord or Contra Costa County when the scope requires it, and we order long-lead items immediately. Custom vanities, specialty tile, and glass enclosures set the calendar.
Demolition and Discovery
We remove the old bathroom down to studs and subfloor where needed, then inspect what the demo exposes. This is the moment when hidden problems become visible, and we walk you through anything we find.
Rough Plumbing, Electrical, and Framing
Supply line replacement (copper or PEX in place of failing galvanized), drain relocation and proper venting, pressure-balanced anti-scald valves, dedicated GFCI circuits, blocking for future grab bars, and exhaust fans ducted fully to the exterior — never into the attic.
Waterproofing and Inspection
We install the waterproofing assembly, flood-test shower pans, and pass the required rough inspections before anything gets covered.
Tile, Fixtures, and Finish Work
Floor and wall tile, shower niches, vanities, countertops, mirrors, glass enclosures, hardware, and paint. We finish with a walkthrough, a written punch list, and completion of every item on it.
Bathroom Projects We Handle
Tub-to-shower conversions
The most requested bathroom remodel bathtub project we do. We remove the tub, rebuild the pan, and install a full walk-in shower with correct drainage.
Curbless and low-threshold showers
We recess the subfloor to keep the floor level at the entry, which requires framing work most bathroom renovation contractors avoid.
Jetted and whirlpool tub installation
For a jetted soaking tub, we frame the platform, run the dedicated circuit, and build the required access panel for the pump motor.
Primary suite bathrooms
Double vanities, freestanding tubs, separate water closets, heated tile floors, and custom glass.
Hall and guest bathrooms
Efficient full remodels on a tighter footprint and a tighter budget.
Powder rooms
Fast cosmetic-to-full updates, often finished in one to two weeks.
Aging-in-place and accessible bathrooms
Grab bars anchored to real blocking, comfort-height toilets, curbless entries, wider doorways, and turning clearance for mobility devices.
Water damage and bathroom reconstruction
Full rebuilds after leaks, overflow events, or long-term hidden moisture, including subfloor and framing replacement.

Local knowledge matters
Concord's postwar housing stock shares a specific set of bathroom problems, including original cast iron drains, undersized venting, and subfloors that were never designed for tile. We have opened hundreds of these walls.

Bathroom remodel cost in Concord tracks size, scope, and finish level. Powder rooms typically run $6,000 to $12,000. Standard hall and guest bathrooms run $15,000 to $30,000. Primary suite bathrooms with custom tile, double vanities, and glass enclosures run $30,000 to $60,000 or more. Tub-to-shower conversions usually land between $12,000 and $25,000 depending on tile selection and whether plumbing moves. Hidden water damage adds cost, which is why we inspect thoroughly before quoting. Your written itemized estimate is free and carries no obligation.
Most bathroom remodels take three to five weeks of construction. Powder rooms often finish in one to two weeks. Primary suite bathrooms with custom work can run six to eight weeks. Add two to four weeks before construction for design, fixture selection, permitting, and material ordering. Custom vanities and specialty tile carry the longest lead times, so we order those first. You receive a written schedule with milestone dates before demolition begins.
Yes. We respond to burst supply lines, overflowing toilets, failed shower pans, and active leaks that damage floors and ceilings. Call (925) 465-6462 any day between 6 AM and 11 PM. We stop the water, remove saturated materials to prevent mold growth, document everything with photographs for your insurance carrier, and then provide a quote for the permanent bathroom reconstruction.
Not the one being remodeled. If your home has a second bathroom, you keep using it throughout and we run dust barriers to protect the rest of the house. For single-bathroom homes we compress the schedule as tightly as the inspections allow and tell you honestly which days the room stays out of service. We never leave a household without a working toilet overnight without discussing it first.
Yes for most real work. Moving fixtures, relocating drains, adding or altering circuits, replacing supply lines, and changing the room's footprint all require permits in Concord. Swapping a vanity or repainting does not. Unpermitted plumbing and electrical work becomes a disclosed defect when you sell, and buyers use it to negotiate. We handle the filing and the inspections as part of your contract.
One-day systems install an acrylic liner over your existing tub or shower surround. They finish fast and they look fine on day one. They also seal in whatever is behind them, including rot, mold, and failing plumbing, and they cannot fix a bad layout or a leaking pan. If your bathroom is structurally sound and you only want a cosmetic refresh, a liner can work. If anything behind the wall is compromised, covering it costs you far more later.
Yes. Tile installed over a soft or water-damaged subfloor cracks and fails, usually within two years. When demolition exposes rot, we cut out the compromised sheathing, replace framing where needed, install new subfloor, and add the proper underlayment for tile. We show you photographs of the damage and price the repair in writing before we do the work.
