The short answer
A mid-range full bathroom remodel in Los Angeles costs about $10,250 to $31,900 by our cost-adjusted figures, and LA contractors often quote $15,000 to $35,000 for a hall bath. What matters most here is the drain. Leaving the toilet and shower where they are keeps the job on a quick LADBS express permit and saves thousands in plumbing.
What a bathroom remodel costs in Los Angeles
Our numbers begin with national remodeling cost data and apply the Los Angeles cost factor of 1.14, published by the U.S. Army Corps of Engineers. In plain terms, the same bathroom costs about 14% more here than the national average.
| Job | Los Angeles (typical range) | US average |
|---|---|---|
| Half bath (powder room) remodel | $4,550–$15,950 | $4,000–$14,000 |
| Full bathroom, cosmetic refresh | $6,150–$19,150 | $5,400–$16,800 |
| Full bathroom remodel, mid-range | $10,250–$31,900 | $9,000–$28,000 |
| Full bathroom, high-end | $15,400–$47,900 | $13,500–$42,000 |
| Primary bathroom remodel | $22,800–$68,400 | $20,000–$60,000 |
| Tub-to-shower conversion | $2,300–$13,700 | $2,000–$12,000 |
| Tile, installed | $11.5–$46/sq ft | $10–$40/sq ft |
| New toilet, installed | $400–$910 | $350–$800 |
| New faucet, installed | $135–$340 | $120–$300 |
Estimates for 2026, including labor and standard parts. Los Angeles prices use the metro's construction cost factor of 1.14 (US average = 1.00) from the U.S. Army Corps of Engineers Area Cost Factors. Your quote depends on access, materials and the condition of the home.
Local guides land in the upper half of that table or above it. A Los Angeles builder's bathroom cost guide prices a guest bath with a tub and shower combo, single vanity, toilet and tile floor at $15,000 to $35,000, a primary bath at $35,000 to $50,000 or more, and a powder room at $8,000 to $15,000. The same guide notes that small bathrooms cost more per square foot, because the valve, toilet and vanity cost the same whether the room is 40 or 80 square feet.

Raised floor or slab: the hidden price of moving a drain
Moving a toilet or shower drain is one of the larger line items in any bathroom, and in the Los Angeles area its cost depends on what the house sits on. A Van Nuys design-build firm gives these budgeting ranges:
| Plumbing scope | Typical LA budget |
|---|---|
| Fixture replaced in the same spot | $500 to $2,500 |
| Drain moved, house on a raised foundation | $2,500 to $6,000 |
| Drain moved, house on a concrete slab | $5,000 to $12,000 or more |
Many 1950s to 1970s houses in the San Fernando Valley sit on raised foundations, so a plumber can reach new drain lines from the crawl space. Most of Orange County is built on slabs, which means saw-cutting a trench through the concrete floor. A toilet also needs a 3-inch drain with a vent close enough to satisfy the plumbing code, which is why a small move can turn into a big one.
What drives an LA bathroom budget
| Choice | Lower cost | Higher cost |
|---|---|---|
| Shower | Tub with tile surround, same spot | Walk-in shower with glass, tub removed ($2,300 to $13,700 for the conversion here) |
| Tile | Ceramic on the walls, about $11.50 per sq ft installed | Large-format porcelain or stone, up to about $46 per sq ft |
| Toilet | Standard model swapped in place, $400 to $910 installed | Wall-hung toilet with a new carrier in the wall |
| Layout | Everything stays | Toilet or shower moved, wall shifted |
Waterproofing and shower rules in Los Angeles
A leaking shower soaks the framing and subfloor long before anyone sees a stain. LADBS and the California codes it enforces set clear rules for how a shower is built.
What LADBS requires of shower walls and glass
The city's bathroom remodel guide says shower floors and walls must be finished with smooth, hard, nonabsorbent surfaces, such as tile or cement, to at least 70 inches above the drain. Any material behind them that is not structural must hold up to moisture. Glass in shower doors and tub enclosures has to be tempered or laminated safety glass, or an approved plastic.
What the inspector checks in the shower
An LA design-build firm that pulls these permits regularly lists the shower items inspectors check under the California Plumbing Code:
- Size: at least 1,024 square inches of floor inside the shower, large enough to hold a 30-inch circle.
- Door: it must swing out and leave at least 22 inches of clear opening.
- Valve: a pressure-balance, thermostatic or combination valve with a maximum of 120°F, which keeps the water temperature steady when someone else opens a tap. An old two-handle valve cannot stay once the wall is open.
- Pan: a continuous waterproof pan tied into the drain and flood-tested before any tile goes down.
- Windows: safety glass in any window whose bottom edge is less than 60 inches above the shower floor.
Ventilation that keeps mold out
A bathroom with a tub or shower needs an exhaust fan of at least 50 cfm when it runs on demand, or 20 cfm if it runs continuously, ducted outside with a backdraft damper. Venting into the attic fails inspection. According to an LA permit expediter, a fan dumping into the attic, a failed pan, a missing anti-scald valve, poor drain slope and missing GFCI outlets are among the items that most often hold up a bathroom final. California's energy code also requires at least one light in the bathroom to be on an occupancy or vacancy sensor that turns it off automatically (Title 24 lighting rules).
Why old LA showers usually need more than new tile
The median Los Angeles home dates from about 1965, according to LA neighborhood data, so many hall baths still have original or second-generation showers. Tile set over sound backer board with the fixtures left alone needs no permit. In practice, once old tile comes off a shower that is more than 20 years old, the backer behind it is often soft. Replacing it and swapping the valve while the wall is open turns the job into an express permit. Plan for that before demolition starts.
Water-saving fixture rules in California
Three layers of rules decide which fixtures go into an LA bathroom.
| Rule | What it covers | Limit |
|---|---|---|
| California Title 20 | Every new fixture sold in the state | Toilets 1.28 gallons per flush, showerheads 1.8 gpm, bathroom faucets 1.2 gpm |
| Civil Code 1101.4 (SB 407) | Single-family homes built on or before January 1, 1994, at any alteration | Replace every toilet over 1.6 gpf, showerhead over 2.5 gpm and faucet over 2.2 gpm in the house |
| LAMC 122.03 | City of LA house or duplex, building permit over $500 | Water-saving shower and toilet devices throughout |
The Title 20 limits come from the state's appliance efficiency regulations, so anything a showroom in California sells already meets them. The surprise for many homeowners is the second row. Remodeling one bathroom in a pre-1994 house means any old toilet, showerhead or faucet in the other bathrooms and the kitchen has to be replaced before the permit is finaled, and sellers must disclose noncompliant fixtures. The city's retrofit list adds the LAMC 122.03 requirement, and a permit of $10,000 or more on a house with gas also requires a seismic gas shut-off valve. Our Los Angeles kitchen guide walks through that full list.
Planning for aging in place
A bathroom remodel is the cheapest time to make the room work for someone with a walker, a bad knee or a wheelchair, because the walls and floor are already open.
| Feature | What it involves | Typical cost |
|---|---|---|
| Wood blocking for grab bars | Added in the wall framing before backer board goes up | Small if done during framing |
| Grab bar | Installed into blocking or studs | $100 to $350 per bar |
| Curbless (zero-threshold) shower | Recessed or sloped floor, linear drain, wider waterproofing | $3,000 to $6,000 or more |
| Wider clearances | Room in front of and beside the toilet | Planning only, unless walls move |
The grab bar and curbless shower prices are national figures from HomeGuide's grab bar and walk-in shower guides. Two LA-specific points matter here. First, recessing the floor framing for a curbless entry is structural work, which moves the project from an express permit into plan check. Second, the code wants a toilet at least 15 inches from its centerline to any side wall or fixture, with a 30-inch-wide space and 24 inches clear in front. In a narrow 1950s hall bath, those numbers often decide whether a wider shower fits at all. If someone in the house uses a wheelchair, have the designer draw the turning space before you choose tile.
Do you need a permit?
In the City of Los Angeles, most real bathroom remodels need one, and most qualify for an express permit with no plan review.
| Bathroom work | Permit | Path |
|---|---|---|
| Paint, mirror, towel bars, floor tile only | No | None |
| Toilet, tub, valve or sink replaced in the same spot | Yes, plumbing | Express |
| Tub-to-shower conversion with nothing structural | Yes, combined permit | Express |
| New circuit, GFCI outlet or exhaust fan | Yes, electrical or mechanical | Express |
| Moving a drain to a new spot | Yes, plumbing | Express, with the combined remodel permit |
| Recessed floor for a curbless shower, moved wall, larger window | Yes, building | Plan check |
LADBS lists bathroom remodels with no structural changes, replacing or adding plumbing fixtures, replacing drywall and exhaust fans among its express permits. The online e-permit is narrower: it covers fixtures, tile, counters and finishes but not new plumbing or wiring cut into existing walls, which go through a Development Services Center. For a moved wall, LADBS wants two floor plans at 1/4 inch to the foot, showing the bathroom before and after along with the rooms beside it.
Fees follow the value of the work. In the city's base plumbing schedule, each new fixture adds $23 and each replaced one $10, and a plan check fee of 90% of the building permit fee applies only when plans are reviewed (LADBS fee breakdown). Inspections are booked through 311, or (213) 482-0000 from outside LA County.
Pasadena, Glendale, Burbank, Santa Monica, Long Beach, Torrance and the Orange County cities run their own permit counters, but they enforce the same state plumbing, electrical and energy codes.
How long a bathroom remodel takes in LA
| Scope | Permit time | Build sequence |
|---|---|---|
| Fixtures swapped in place | Same day to 1 or 2 weeks | Demo, rough-in, final |
| Fixtures moved or shower enlarged | About 3 to 8 weeks | Adds a rough plumbing test before walls close |
| Gut remodel with structural change | About 6 to 14 weeks | Adds framing inspection and plan check corrections |
The permit times come from the LA expediter cited above. On site, the work follows a fixed order: demolition to the studs, framing repairs and grab bar blocking, rough plumbing, electrical and fan (one rough inspection on a combined permit), backer board and waterproofing with the pan flood test, then tile, fixtures, glass and the final inspection. Glass is measured after the tile is done. If this is the only bathroom in the house, agree with the contractor on how you will have a working toilet each night.
Is a bathroom remodel worth it in Los Angeles?
Bathrooms return more of their cost on the West Coast than the national average. The 2025 Cost vs. Value report found that a midrange bathroom remodel in the Pacific region cost $27,710 on average and added $25,217 in resale value, recovering 91% of its cost. The national figure was about 80%.
How to check a bathroom remodeler before you hire
In California, the Contractors State License Board licenses the people who build bathrooms:
| License | Who holds it | When you need it |
|---|---|---|
| B General Building | Remodelers who manage several trades | A full remodel with plumbing, electrical, tile and drywall |
| C-36 Plumbing | Plumbers | Valve, drain or fixture work on its own |
| C-54 Ceramic and Mosaic Tile | Tile setters | Tile-only jobs, or as the remodeler's sub |
| C-10 Electrical | Electricians | New circuits, heated floors, fan wiring |
A B contractor needs at least two unrelated trades on the job, and carpentry does not count toward the two.
- Look up the license on the CSLB site, and confirm it is active and the name matches.
- Ask how they build the shower pan, which waterproofing system they use, and whether they flood-test before tile.
- Ask who pulls the permit and whether the bid includes replacing old fixtures elsewhere in the house if it was built before 1994.
- Keep the down payment at $1,000 or 10% of the price, whichever is less, as California law requires (CSLB).
An unlicensed handyman can only take jobs under $1,000 that need no permit, which rules out any shower or toilet replacement. Our guide to paying a contractor covers milestones and lien releases. For plumbing problems outside a remodel, see our Los Angeles plumbing guide.

Frequently asked questions
How much does a bathroom remodel cost in Los Angeles?
By our cost-adjusted figures, a mid-range full bathroom costs about $10,250 to $31,900, a powder room $4,550 to $15,950 and a primary bath $22,800 to $68,400. Local LA contractors often quote $15,000 to $35,000 for a hall bath. Moving drains, especially on a slab, pushes costs higher.
Do I need a permit to remodel a bathroom in Los Angeles?
Yes, if you replace or move a toilet, tub, shower valve or sink, add a circuit or install a fan. LADBS issues an express permit when nothing structural changes. Paint, accessories and floor tile alone need no permit. Moving a wall or recessing the floor for a curbless shower requires plan check.
What does a Los Angeles inspector check in a new shower?
Smooth, nonabsorbent walls to at least 70 inches above the drain, a waterproof pan flood-tested before tile, an anti-scald valve set to 120°F at most, safety glass, a door that swings out with a 22-inch opening, and an exhaust fan ducted outside, never into the attic.
Do I have to replace all my old toilets when I remodel one bathroom?
If your LA house was built on or before January 1, 1994, yes. California Civil Code 1101.4 requires replacing every toilet over 1.6 gallons per flush, showerhead over 2.5 gpm and faucet over 2.2 gpm in the house as part of any permitted alteration. Budget for it in the bid.
How much does it cost to move a toilet in an LA bathroom?
A Los Angeles builder budgets $2,500 to $6,000 to relocate a drain in a house on a raised foundation, common in the San Fernando Valley, and $5,000 to $12,000 or more on a concrete slab. Replacing a toilet in place costs about $400 to $910 here.
Can I get a curbless shower in an older Los Angeles house?
Usually, but recessing the floor framing for a zero-threshold entry is structural work, so it needs plan check rather than an express permit. Barrier-free showers cost about $3,000 to $6,000 or more nationally. Add grab bar blocking while the walls are open.
Is a bathroom remodel worth it in Los Angeles?
In the Pacific region, a midrange bathroom remodel recovered 91% of its cost at resale in the 2025 Cost vs. Value report, against about 80% nationally. That project averaged $27,710 in cost and added $25,217 in value. Keeping the layout and drains in place is the easiest way to stay near that budget in Los Angeles.
How we calculate these prices
GOLDGCP starts from national price ranges for each job, taken from published 2026 cost guides and checked against local price guides where they exist. To get a local price, we multiply the national range by the construction cost factor for the metro from the U.S. Army Corps of Engineers Area Cost Factors (US average = 1.00). For ZIP codes outside the 50 largest metros, the calculator uses the state's price level from the Bureau of Economic Analysis Regional Price Parities. Ranges include labor and standard materials but not unusual site conditions, so a written quote after an inspection is always the final price.
