AfterFast, Reliable Bathroom Remodeling Across Northridge
Bathroom remodeling in Northridge typically runs $9,000 – $28,000 for a full gut-and-rebuild, and the price depends heavily on one thing most contractors won’t ask about up front: whether your property sits on a private well and septic system or on city sewer. Roughly 40% of Northridge’s single-family homes predate the sewer expansion, which means a permit from LA County Environmental Health can enter the picture for something as routine as moving a shower drain. We scope that before quoting, so the number we hand you in writing is the number you pay. Call Penhallow Remodeling at (936) 259-2607 for a free estimate and a straight answer.
Why Penhallow Remodeling Is Northridge’s Preferred Bathroom Remodeling Company
Trevor Nash runs our Bathroom Remodeling team with a rule that’s simple to say and hard to fake: say the price before the work, show up in the window we gave, leave the job site cleaner than we found it. That’s The Kingswell Way, and it’s been the operating standard since 2004. Every Northridge project gets a written price and a written 365-Day Done Right Promise before demolition starts. If something fails inside that year, we come back and fix it at no charge. No re-inspection fee, no service call, no argument.
Our background-checked, uniformed technicians know Northridge’s housing stock. They know the 1950s tract ranch on a septic lot off Balboa Boulevard behaves differently than the 1996 earthquake rebuild near CSUN that shares a sewer line. They know which jobs will trigger a city LADBS plan check only, and which ones will also need a county sign-off on septic capacity. That’s not knowledge you get from a nationwide franchise call center. It’s knowledge you get from doing the work locally, every week. A live person answers our phone 24/7, not a voicemail maze.
Shower Remodel in Northridge
A Shower Remodel in Northridge usually means tearing out a tired 1960s or 1970s fiberglass or tile surround, repairing the framing behind it, and rebuilding the shower with modern waterproofing, a new pan, and new tile or solid-surface walls. In this neighborhood, the behind-the-wall work is often more important than the finish. Homes that went through the 1994 Northridge Earthquake frequently have cracked mud beds or separated drain connections that nobody sees until the tile comes off. A typical shower remodel here runs $3,000 – $8,500 for a replacement, and $4,500 – $12,000 if we’re building a new walk-in shower from scratch.
What Gets Replaced
We remove the old surround down to the studs, inspect the framing for earthquake damage or moisture rot, and replace what’s compromised before anything new goes up. Cement board substrate (the moisture-resistant layer behind your tile) goes in next, followed by a waterproofing membrane, a sloped pan, and your finish material. We install Kohler and Moen fixtures, and we can use Cambria or Silestone solid surface for a shower that’s easier to maintain than grout lines.
When Septic Matters
If your shower drain moves more than a few inches, and your Northridge home is on a septic system, the county wants to verify the system can handle the fixture before the city will sign off on the rough-in. We pull that county septic permit alongside the city building permit so the job doesn’t stall mid-demolition. The good news: on a half-acre lot off Devonshire Street near Zelzah Avenue, we remodeled a 1970s ranch bathroom where the existing shower drain ran through the planned new shower footprint. By rerouting the drain to keep the 100-foot well setback clear, the owners avoided a $15,000 septic upgrade and still got their new shower. That’s the kind of thing you only learn by asking the right questions before you quote.
Tub to Shower Conversion in Northridge
A Tub to Shower Conversion in Northridge replaces a rarely-used bathtub with a curbless or low-curb walk-in shower, and it’s the single most common request we get from homeowners in their 50s and 60s who want to stay in their homes as mobility changes. In Northridge’s 1950s tract homes, the original bathrooms are often 5 feet by 8 feet, which means a standard 60-inch tub footprint works well for a shower built in the same space. A tub-to-shower conversion in Northridge runs $3,500 – $10,000 depending on whether we’re keeping the existing drain location or moving it.
Drain Location and Permits
If the new shower drain can stay where the tub drain was, the job is simpler and cheaper. If it moves, and the home is on septic, the county environmental health review kicks in, and so does the possibility of a septic capacity upgrade. We verify that before we quote. On sewer-connected homes, the city permit is usually all we need, and even that sometimes requires a structural correction if the 1994 earthquake damaged the framing behind the tub surround.
Floor Repair Before Tile
We always inspect the subfloor under the tub before installing the new shower pan. In Northridge, we regularly find water damage that’s been hidden under a tub for decades, and in post-quake rebuilds we sometimes find joists that were sistered hastily in 1995 and have since settled. Fixing the subfloor before the shower pan goes in is the difference between a shower that lasts 20 years and one that cracks six months after you pay the final invoice. Our written price includes any subfloor repair we can see during the initial scope, and if demolition reveals something hidden, we show you photos and give you a written change order before spending another dollar.
Trusted Brands We Service in Northridge
We install KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone countertops, and Kohler and Moen fixtures on Northridge remodels. These aren’t bargain-bin products; they’re trade brands with their own warranties that sit alongside our 365-Day Done Right Promise. When a Kohler valve fails inside our guarantee period, you get a replacement and our labor at no charge. When a Silestone countertop arrives with a factory defect, we handle the replacement. For faster-turnaround Northridge jobs, we may recommend modular construction systems from Abodu or Cover for prefabricated elements, though every site-built bathroom still follows the same written-price, written-guarantee standard. We stock common replacement parts locally so a warranty repair doesn’t wait on a shipment from the East Coast.
Common Bathroom Remodeling Problems We See in Northridge Homes
- Septic capacity surprises: Homes on private septic systems north of the city sewer line often have systems sized for the original fixture count from 1958. Add a second shower head or move a drain, and the county can require a $10,000+ septic upgrade before the bathroom permit closes.
- 1994 earthquake damage behind the tile: Post-quake emergency repairs were fast. OSB nailed over damaged cripple wall framing without replacing the sill plate, cracked shower pans patched with silicone, and drain lines that shifted. We open walls and check before we quote, not after.
- Well setback conflicts: Moving a bathroom fixture on a well-served lot can put you inside the 100-foot setback from the wellhead. That triggers a county review and sometimes a redesign. We map the well location during the estimate so you know before you sign.
- Subfloor rot under original tubs: Sixty-year-old cast iron tubs on slab foundations sometimes hide slow drain leaks that have been eating the subfloor for decades. The rot doesn’t show until the tub comes out, and then the job changes. Our written price accounts for what we can see and our change-order process handles what we can’t.
Pricing for Bathroom Remodeling in Northridge, CA

What moves the price up or down? The septic versus sewer question is the big one in Northridge. A sewer-connected remodel off Reseda Boulevard can often move a drain without a second permit. The same remodel on a well-and-septic lot near Limekiln Canyon may need a county environmental health review and a septic capacity check. Finish materials matter too: a standard tile surround costs less than a full-height Cambria quartz shower wall. The size of the vanity, the number of fixtures you’re moving, and whether the 1994 earthquake left structural corrections behind your walls all change the final number. Call (936) 259-2607 and we’ll come out, look at the actual property, and hand you a written price. Free.

FAQs About Bathroom Remodeling in Northridge
Yes, in most cases where a fixture moves or the septic line is touched. The City of Los Angeles issues the building permit through LADBS, but LA County Environmental Health must sign off on septic capacity and well setback compliance before the city will close the permit. If the fixture stays in place and the drain doesn’t move, you may only need the city permit. We verify this during the free estimate, not after demolition starts. Call (936) 259-2607 to get a clear answer for your specific property.
The earthquake split Northridge’s housing stock into pre-1994 original construction and post-quake rebuilds, and both carry risk. Pre-quake homes often have unretrofitted cripple walls and sill plates that were damaged but never repaired. Rebuild-era homes sometimes have fast-tracked framing repairs that passed a rushed inspection in 1995 but wouldn’t pass today. We open the wall behind the shower and check the framing before we quote, and if we find structural damage, we pull it into the scope with a written change order. A bathroom remodel is the right time to fix it, because the wall is open anyway.
A full bathroom remodel in Northridge runs $9,000 – $28,000. The biggest cost drivers are whether you’re on septic or sewer, whether the 1994 earthquake left hidden structural damage, how many fixtures you’re moving, and the finish level you choose. A small bathroom remodel on a sewer-connected lot with standard tile runs $5,000 – $12,000. A walk-in shower with a Cambria quartz surround and a relocated drain on a septic lot will land closer to the top of the range. We give you a written line-item price before any work starts, so the number on day one is the number on the invoice.
Yes. Most original Northridge tract bathrooms are 5 feet by 8 feet, and the standard 60-inch tub footprint converts cleanly to a shower in the same space. The limiting factor is usually not the room size but the drain location and whether the subfloor under the old tub is sound. If the drain can stay put and the floor is solid, the conversion is straightforward and runs $3,500 – $6,000. If the drain moves and the home is on septic, the county review adds time and possibly cost. We’ll tell you which scenario you’re in before you sign anything.
Most Northridge bathroom remodels take four to seven weeks from the day permits are issued to the final inspection sign-off. City-only permits on sewer-connected homes typically issue faster, sometimes within two weeks. Septic-and-well properties that need a county environmental health review can add one to three weeks to the permit phase. The construction phase itself is usually three to five weeks depending on scope. We give you a written schedule with a real arrival window before we start, and if a delay comes up, we tell you the day we know about it, not the day you call to ask. Call (936) 259-2607 for a free estimate and a schedule for your specific project.
