AfterFast, Reliable Bathroom Remodeling Across Lomita
A full bathroom remodel in Lomita typically runs $9,000 to $28,000, and the two factors that swing that number most are whether your 1940s – 1960s tract home hides structural surprises behind the walls and whether your contractor knows Lomita’s own building department cadence. We’re Penhallow Remodeling, and we’ve spent enough time in Lomita’s postwar housing stock to know that a “simple” shower swap can turn into structural work the moment the subfloor comes up. Call (936) 259-2607 if you want a written price before a single tile is pulled, and a contractor who actually knows this city’s permit desk.
Why Penhallow Remodeling Is Lomita’s Preferred Bathroom Remodeling Company
Lomita runs its own municipal building department, not LA County’s system. That one fact changes how a remodel gets scheduled, inspected, and signed off. A contractor who treats Lomita like just another county permit job hits inspection scheduling delays mid-rough-in, and your draw schedule stalls while the tile guy waits. We’ve pulled enough Lomita permits to know exactly how the city’s inspectors sequence their sign-offs on bathroom work, so the job moves instead of sitting. When our crew arrives in uniform and background-checked, they already know what the Lomita inspector is going to look for behind the cement board.
Trevor Nash, who leads our team, insists on one thing before any Lomita job starts: a written price. Not a verbal ballpark. Not a range with a shrug. A number you can hold us to, backed by our 365-Day Done Right Promise. If the work fails inside a year, we come back and fix it at no charge. That guarantee is in writing on every project, because a guarantee that isn’t written down is just a handshake.
We also answer the phone. A live person, 24/7. No voicemail maze when you call about a shower pan that’s been weeping into the subfloor for six months. That matters more in Lomita than most places, because the marine layer keeps moisture hanging around long enough to rot a subfloor that a cheaper contractor waterproofed wrong the first time. Our Bathroom Remodeling team has seen what that humidity does to the wood-frame homes off Lomita Boulevard and Narbonne Avenue, and we spec materials accordingly.
Shower Remodel in Lomita
A Shower Remodel in Lomita means more than swapping tile and a showerhead; it means making sure whatever sits behind that tile survives the city’s year-round moisture load. On the postwar wood-frame homes that make up most of Lomita, we typically rebuild the shower from the studs out, replacing any damaged framing, installing a cement-board backer (the moisture-resistant layer behind your tile), and then waterproofing the entire envelope with a full membrane before a single piece of tile goes up. A shower remodel here runs $3,000 to $8,500 depending on size, tile choice, and what we find once the old surround comes down.
Waterproofing the Marine Layer Way
Lomita sits at the inland edge of the South Bay marine layer zone, so humidity stays elevated year-round. That’s why we don’t use greenboard behind Lomita shower tile; it wicks moisture and fails. We use cement board and a full waterproofing membrane, because the city’s inspection cadence means catching a moisture problem at rough-in is cheaper than finding it two seasons later as rot.
When the Subfloor Tells the Real Story
On a shower remodel, the first thing we do after demolition is check the subfloor and joists. On Lomita homes built in the 1950s, we regularly find original 2×6 floor joists that were undersized the day they were installed. Sistering those joists before we set the shower pan is standard practice for us, and it’s a written change order, not a surprise on the final invoice.
Tub to Shower Conversion in Lomita
A Tub to Shower Conversion in Lomita is one of the smartest moves for an aging bathroom, whether you want a walk-in shower that’s easier on the knees or you’re tired of soaking in a 1950s tub that’s lost its enamel. This job runs $3,500 to $10,000 in Lomita, and the price hinges on what the old tub surround hides once it’s opened up. On the tight-lot tract homes this city is known for, that often means structural fixes before the new shower base ever goes in.
Structural Work Behind the Tile
Many Lomita homes still sit on unbolted cripple-wall foundations. That’s a seismic vulnerability, but it’s also a remodeling reality: when we open a bathroom wall on a home off Pennsylvania Avenue and find an unbolted cripple wall, we brace and anchor-bolt it as part of the rough-in. Your Lomita inspector won’t sign off on a remodel that ignores it, and neither will we.
Moisture and the Old Tub Surround
The marine layer that keeps Lomita evenings cool also keeps wood damp. If your old tub surround was caulked and painted over instead of properly waterproofed, chances are there’s hidden rot at the tub flange. We cut out the damaged framing, replace it, and waterproof the whole space so the shower you’re converting to doesn’t inherit the old tub’s moisture problem.
Trusted Brands We Service in Lomita
We install and service fixtures and materials from brands that back their own work, because a warranty from us means more when the product behind it carries its own. On Lomita bathroom remodels, we regularly work with Kohler and Moen fixtures, Cambria and Silestone countertops, and KraftMaid and Wellborn cabinetry. Cambria quartz carries a lifetime warranty from the manufacturer, which layers on top of our written 365-Day Done Right Promise. We keep common trim and fixture parts stocked for Lomita jobs, so a scratch-and-dent replacement at final walkthrough doesn’t turn into a two-week wait.
Common Bathroom Remodeling Problems We See in Lomita Homes
- Unbolted cripple-wall foundations. Lomita’s 1940s – 1960s tract homes frequently predate mandatory seismic anchor bolt requirements. We brace and bolt these during rough-in, with written change orders, because the Lomita inspector will flag them anyway.
- Marine-layer moisture intrusion. The South Bay humidity seeps into improperly waterproofed shower pans and tub surrounds, rotting subfloors and framing. We spec cement board and full waterproofing membranes, not greenboard, on every Lomita shower.
- Undersized original framing. A lot of postwar Lomita homes were framed with 2×6 joists where modern code wants more. When we open a bathroom floor, we sister joists as needed before setting a tub or shower pan, so the tile doesn’t crack two years later.
- Wrong-jurisdiction permitting. Because Lomita runs its own building department, hiring a contractor who thinks in LA County terms means missed inspection windows and stalled work. We schedule rough-in and final inspections on Lomita’s cadence from day one.

FAQs About Bathroom Remodeling in Lomita
Yes, and Lomita issues its own permits through the city’s municipal building department, not LA County’s system. A compliant bathroom remodel in Lomita requires a permit for any plumbing, electrical, or structural changes, and the city inspects on its own cadence. We pull every permit ourselves and schedule inspections to match Lomita’s sequencing, so your rough-in and final sign-offs happen without weeks of waiting. Call (936) 259-2607 if you want a contractor who actually knows Lomita’s permitting desk.
Because Lomita’s housing stock is overwhelmingly small postwar tract homes from the 1940s through early 1960s, many sitting on unbolted cripple-wall foundations with undersized original framing. When we open a bathroom wall or floor, we often find 2×6 joists that need sistering or a cripple wall that needs anchor-bolt bracing before the tile goes up. We handle those as written change orders, priced and explained before we do the work, never as a surprise on the final bill.
A compliant Lomita quote includes the permit fee, the structural remediation (sistered joists, cripple-wall bracing), cement-board backer with a full waterproofing membrane, and a written inspection schedule that matches the city’s cadence. A cheap bid omits the waterproofing and structural scope, then either stalls at inspection or hands you a change order after demo day. Our written price includes what the Lomita inspector will actually require. Call (936) 259-2607 for a quote that accounts for it from day one.
The marine layer keeps Lomita damp year-round, and that moisture gets behind improperly waterproofed shower pans and tub surrounds, rotting the subfloor and framing beneath. On every Lomita shower or tub-to-shower conversion, we use cement-board backer and a full waterproofing membrane, because greenboard fails in this climate. It costs a little more up front, and it means the tile and the framing under it are still dry two seasons later.
Yes. We regularly install Kohler and Moen fixtures, Cambria, Silestone, and Caesarstone countertops, and KraftMaid and Wellborn cabinetry on Lomita bathroom remodels. Cambria quartz carries its own lifetime manufacturer warranty, which layers on top of our written 365-Day Done Right Promise, so you have two warranties backing the same surface. Call (936) 259-2607 for specifics on what fits your Lomita bathroom.
We pulled a bathroom remodel permit on a 1952 tract home near Lomita Boulevard, and once we opened the subfloor we found the original 2×6 floor joists and an unbolted cripple wall that would never have passed a Lomita inspection sign-off. We added sistered joists and anchor-bolt bracing as a written change order before setting the Kohler tub. Because that whole envelope sits in the South Bay marine layer, we also spec’d a cement-board backer and a full waterproofing membrane rather than the greenboard a cheaper bid would have used. Two seasons later the tile and the framing under it are still dry.
This page exists because Lomita’s own building department cadence and its unbolted cripple-wall housing stock create remodeling conditions that generic bathroom-remodeling content never addresses. A compliant, inspection-papered quote in Lomita includes structural remediation and marine-grade waterproofing that a cheap bid quietly omits. If you’re planning a bathroom remodel in Lomita, call (936) 259-2607 for a free estimate, and we’ll put the price in writing before a single tile comes up.
