BATHROOM REMODELING
Bathroom Remodeling Contractor in
Norwalk, CA
With more than 10 years of experience, ARD Remodeling remodels bathrooms for homeowners in Norwalk, CA, from a new vanity and faucet to a rebuilt tub-shower. Three local facts shape most plans here: the tap water is hard, nearly every home is old enough for the state's water-saving fixture rule, and one bathroom often serves a full household. The free estimate starts with those three, so the finishes, the fixtures and the paperwork route are clear before any tile is ordered.

Water
What Norwalk's hard water means for a new shower
The utility's 2026 report on its Norwalk system, covering 2025 results, gives hardness as 137 to 505 mg/L with an average of 310. In grains per gallon, the unit used for sizing water softeners, that is 8.0 to 30 with an average of 18. The report describes the supply as a blend of treated groundwater and imported water, so the mineral load at your tap can move with the blend. If your address is on this system, those numbers guide the finishes we suggest. Your water bill shows who supplies your home.
Spots show on glass and dark metal
Clear glass and matte-black fixtures show mineral spots fastest. Textured glass and brushed finishes are more forgiving, and we explain the upkeep of each before you choose.
Narrow joints, sealed surfaces
Minerals have less to cling to on tile with slim grout lines and a sealer. We write the cleaning routine for your tile into the handover.
A softener changes the question
If you own a softener, or plan to add one, tell us at the estimate. It changes which finishes need the least care.
THE NORWALK COUNTER
What to tell City Hall about a bathroom job
A planning aid, not a ruling. The city's staff decide how a job is handled.
Have ready when you call
- The address and the year the house was built
- Which fixtures change, such as the toilet, tub, shower or sink
- Whether any drain or supply line moves
- Whether the tub or shower footprint changes
- Whether the building holds more than one unit
Only the city can answer
- Whether the job is reviewed over the counter or sent to plan check
- Which forms and drawings the job needs
- How the water-saving fixtures are checked at final
- Whether a single-family or multifamily reading fits your unit

State law
Homes built before 1994 and the state fixture rule
California's SB 407, now Civil Code section 1101.4, makes replacing every noncompliant plumbing fixture a condition of final permit approval for alterations to a single-family home. The statute's target is property built and available for use on or before January 1, 1994. The SCAG housing table shows only about 6 percent of Norwalk's units dating from 1990 or later, so for most local bathrooms this rule belongs in the plan from the first visit.
Old means above three limits
The text counts toilets above 1.6 gallons per flush, showerheads above 2.5 gallons per minute and interior faucets above 2.2 gallons per minute as noncompliant.
Listed in the scope
The replacements are checked before the permit is finalized, so we write them into the scope instead of leaving them for the last day.
A room rule for larger buildings
For property with more than one unit, the same law has its own section, including a rule for the room being altered. We ask how it reads for your unit.
TUB, SHOWER OR BOTH
Three ways to rework a hall bath
Decide this early. It sets the framing, the drain and the waterproofing.
Keep the tub, renew the surround
Best for: Households with small children
- The tub and drain stay where they are
- New tile or a solid surround, with a new valve and showerhead
Keep in mind: The tub walls take the most water, so the waterproofing behind the tile matters most.
Convert the tub to a shower
Best for: A bath where the tub is rarely used
- A low-curb or curbless floor
- A wider opening for easier entry
Keep in mind: The drain position and floor framing decide how the slope is built, so we check both first.
Tub-shower with a sliding door
Best for: Keeping the tub while adding glass
- One valve and one drain to serve
- A door in place of a curtain
Keep in mind: Hard water spots glass quickly, so plan a squeegee routine.
THE LOWER WALL
Half-height tile for a splash-prone room
In a modest bathroom, tile that stops at chair-rail height can protect the walls beside the tub and vanity without closing in the room. Paint above keeps it light. We choose the tile, the cap trim and the paint finish together so the edge looks planned.
- Tile where it splashesThe wall beside the tub and behind the vanity gets the hard-wearing surface.
- Paint aboveA washable finish over the tile keeps the upper wall bright.
- A clean cap lineThe trim height is set to line up with the vanity and the window sill.
Living through it
One bathroom, a full household
More people per home means fewer spare minutes and fewer spare fixtures. Before demolition we map the sequence with you: plumbing and wall work, then waterproofing and tile, then glass and fixtures. We also ask which matters more on a given day, a working toilet or a working shower, and order the work around the answer.
Where everyone washes
Pick the backup before demolition starts, whether a second bath, a relative's home or a gym membership.
Water-off days are known
We tell you which days the supply to the bathroom is shut off, so laundry and dishes can be planned around them.
BEFORE WE COME
Notes that help at a bathroom estimate
Rough answers work.
- 1The year the house was built, if you know it
- 2Whether the whole household shares this bathroom
- 3Which fixtures you want to replace and which to move
- 4Whether you have a water softener
- 5Any soft floor, stain or leak you have noticed
- 6Photos of every wall, the tub and the ceiling
Skip anything you do not know. We will work it out together at the visit.

Hard water in the local supply
The 2026 Consumer Confidence Report on water quality for 2025 lists, for the Norwalk Water System, hardness as CaCO3 of 137 to 505 mg/L (average 310), or 8.0 to 30 grains per gallon (average 18), and defines one grain per gallon as 17.1 mg/L of hardness.

Water-saving fixtures
As chaptered, section 1101.3 of the Civil Code names three noncompliant fixtures: a toilet built to use over 1.6 gallons per flush, a showerhead rated above 2.5 gallons per minute and an interior faucet delivering more than 2.2 gallons per minute. Section 1101.2 applies the article to property built and available for use on or before January 1, 1994, and from January 1, 2014 section 1101.4(a) makes replacing those fixtures a condition of final permit approval for alterations to single-family property. For multifamily property, section 1101.5(d)(1)(C) covers a room altered under a building permit.

- Permits
- Clear scope
How hard is the water in Norwalk?
Golden State Water's 2026 report for its Norwalk system lists hardness of 8.0 to 30 grains per gallon, averaging 18. Your bill shows who supplies your address, and we plan the finishes around it.
Does the year my house was built matter for a bathroom remodel?
California's water-saving fixture law targets property built and available for use on or before January 1, 1994. Nearly all Norwalk homes fall on that side of the line, so a permitted remodel of a single-family bathroom can bring new toilets, showerheads and faucets with it.
What counts as an old fixture?
The state text lists toilets built for more than 1.6 gallons per flush, showerheads above 2.5 gallons per minute and interior faucets above 2.2 gallons per minute. We note which of yours fall into those groups at the estimate.
Can I turn the tub into a shower?
Usually we can. Before drawing it up we look at where the drain sits, how the floor is framed and whether another tub remains in the house. The city decides how the change is handled.
How do I get a time at the city counter?
Call Building & Safety at (562) 929-5733 or stop by Room 12 at City Hall. The city lists technician appointments on workdays from 9 to 11 a.m. and 2:30 to 4:30 p.m.
Does the state rule apply in a condo or apartment?
The law has a separate section for buildings with more than one unit, with a room rule for permitted alterations. How it reads for your unit is worth confirming with the city and your association, and we ask early.
