Fast, Reliable Bathroom Remodeling Across South Gate
A full bathroom remodel in South Gate typically runs $9,000 – $28,000, and a walk-in shower installation usually falls between $4,500 and $12,000. Those are the numbers we quote from, and we put them in writing before any work starts. If you live south of Firestone Boulevard, your project also carries floodplain requirements most neighboring cities never deal with. Call (213) 277-6578 for a free estimate, and we’ll walk you through exactly what your home needs.
South Gate homes were mostly built between the 1920s and 1960s. That means single-story stucco and wood-frame construction, original foundations, and bathrooms that have seen decades of moisture and patch jobs. We know these houses because we work in them every week, from Tweedy Boulevard down to the neighborhoods south of Firestone. Our crews understand what’s behind those walls before we open them up, and that matters when you’re spending five figures on a room you’ll use every day.
You’ll get a real person when you call. You’ll get a written price before demolition starts. And you’ll get the 365-Day Done Right Promise on every project: if the work fails inside a year, we come back and fix it at no charge. That’s the standard Trevor Nash set for this company, and it’s the standard every South Gate job is held to.
Why Penhallow Remodeling Los Angeles Is South Gate’s Preferred Bathroom Remodeling Company

We’re part of the Kingswell family of companies, operating under the Kingswell Guarantee since 2004. Every job gets a written price up front, a defined arrival window, a clean job site, and a written guarantee. We don’t do verbal ballparks that inflate after demo day. The number you approve on day one is the number on your final invoice.
Our technicians are background-checked and arrive in uniform. You’ll know exactly who’s walking into your home, and they’ll respect the fact that you’re living there while the work happens. A live person answers our phone 24/7, including weekends. South Gate homeowners calling from Hollydale, Tweedy, or near South Gate Park won’t hit a voicemail maze.
Materials come from brands that stand behind their products the way we stand behind our labor. We install Kohler and Moen fixtures, Cambria and Silestone countertops, and KraftMaid cabinetry. When a product carries its own warranty alongside our 365-Day promise, you get two layers of protection, not one.
Trevor Nash leads this location. He’s the owner who writes the guarantee and signs the price sheet. That level of accountability is rare, and South Gate homeowners who’ve been burned by a no-show contractor or a price that doubled after the walls came down tend to notice the difference immediately.
Styles & brands we work with







Bathroom Remodeling Contractor in South Gate
A Bathroom Remodeling contractor in South Gate deals with a specific set of conditions: aging plumbing, outdated electrical, and flood zone compliance south of Firestone Boulevard. A full remodel here means more than swapping a vanity and re-tiling a shower. It often means rewiring circuits, replacing cast-iron drain lines, and coordinating with city inspectors on elevation requirements. Our team handles all of it, start to finish, with the permit path mapped out before the first wall comes down.
Permit and Inspection Coordination
We pull permits for every South Gate bathroom remodel that requires them, and we coordinate the inspections that follow. South Gate’s building department enforces local amendments to California code, including floodplain provisions that neighboring cities like Downey and Huntington Park don’t apply. If your home sits in FEMA Zone A or AE, your finished floor must sit above Base Flood Elevation, and your foundation walls need flood vents. We verify your flood zone status before we quote, so there are no surprises at inspection time.
Complete Bathroom Remodeling Scope
Our full remodels cover everything from layout changes to finish trim. That includes demo and disposal, plumbing rough-in, electrical upgrades, waterproofing, tile work, vanity installation, fixture mounting, and final paint. A typical South Gate full bathroom remodel runs $9,000 – $28,000 depending on square footage, fixture selection, and the amount of subfloor or framing repair required. We give you a line-item written quote so you can see exactly where each dollar goes.
Walk In Shower in South Gate

A walk in shower installation in South Gate runs $4,500 – $12,000, and it’s one of the most common requests we get from homeowners replacing a cramped tub or an aging fiberglass enclosure. These projects make sense for South Gate’s older single-story homes, where a curbless or low-threshold shower improves access and opens up a small bathroom visually. We frame the shower, install the waterproofing, set the pan, tile the walls, and mount the glass enclosure.
Waterproofing and Drain Assembly
We use cement board substrate (the moisture-resistant layer behind your tile) and a waterproof membrane on every walk-in shower. In flood zone homes south of Firestone, we also install a flood-rated drain assembly and coordinate any elevation adjustments with your plumbing rough-in. This matters for insurance: a properly documented flood-compliant shower is defensible in a claim. A shower built without that documentation is a liability waiting for the wrong storm.
Frameless Glass Shower Enclosures
Frameless glass enclosures are the finish that makes a walk-in shower feel complete. We measure after tile is set, order glass through our local fabricator, and install once it’s ready. Expect about a week between final measurement and installation. The glass is tempered, the hardware is solid, and the result is a shower that’s easy to clean and looks like it belongs in a magazine.
Trusted Brands We Service in South Gate
We install and service fixtures and materials from brands with standing warranties, which means your remodel carries more than just our 365-Day Done Right Promise. Kohler and Moen faucets, showerheads, and valves are the most common we mount in South Gate bathrooms. Cambria and Silestone quartz countertops bring their own lifetime warranties alongside our labor guarantee. We keep common replacement parts for these lines stocked locally so a warranty repair doesn’t mean waiting two weeks for a part out of a regional warehouse. When you call about a leaking Moen cartridge or a Kohler valve that’s stuck, we can usually source the part same day and schedule the repair inside a week.
Common Bathroom Remodeling Problems We See in South Gate Homes
- Flood zone surprises south of Firestone. Bathrooms in FEMA Zone A or AE need finished floors above Base Flood Elevation and flood vents in foundation walls. Miss that requirement, and you’re redoing rough-in work after a failed inspection.
- Asbestos in 1950s stucco-and-drywall bathrooms. Cutting into a wall or ceiling without testing can trigger a stop-work order. Abatement costs then land on top of your remodel budget, not inside it.
- Cast-iron drain lines at the end of their life. Homes built in the 1940s and 1950s often have original cast-iron under the slab. It rusts from the inside out, and replacing it mid-remodel adds real cost. We inspect first, quote first, and you never discover it on accident.
- Foundation settlement from the high water table. South Gate sits atop the Los Angeles Basin with groundwater close to the surface. Slab movement cracks tile and grout. We address substrate stability before we set anything that can’t flex.

FAQs About Bathroom Remodeling in South Gate
No. Replacing a vanity, toilet, and fixtures in their existing locations does not trigger a flood zone permit. Floodplain requirements apply when you alter the finished floor elevation, move plumbing rough-in, add square footage, or modify foundation walls. That said, if your home is south of Firestone Boulevard in Zone A or AE, you should verify your flood zone status before any remodel work that touches the floor or foundation. Call (213) 277-6578 and we’ll check it for you during the estimate.
South Gate falls under Los Angeles County wind zones, with standard bathroom exhaust fans and roof vents rated for 90 – 110 mph uplift depending on exact location and roof height. Your building official may require documentation confirming the rating. A compliant quote includes the correct rated vent or fan assembly, the manufacturer’s compliance sheet, and the inspection step that verifies installation. A cheap quote leaves that out and hopes nobody looks.
Documented compliance is what lets you file a claim after a flood without the insurer denying it on the basis of unpermitted work or improper elevation. If your remodel south of Firestone includes flood vents and properly elevated finished floors, and that work is permitted and inspected, you can hand the adjuster the paperwork. Without it, the insurer may argue the bathroom itself increased flood risk and void or reduce your claim. We keep every permit, inspection record, and code compliance document in the project file for exactly this reason.
A compliant quote includes flood zone verification, flood-rated drain assemblies if needed, elevation adjustments for finished floors, flood vents in foundation walls, wind-rated exhaust fan or roof vent assemblies, asbestos testing on pre-1978 homes, permit fees, and inspection coordination. A cheap quote includes the tile, the vanity, and a handshake. The difference shows up at the first inspection. Call (213) 277-6578 for a written quote that includes what the city actually requires.
Yes, you can convert your bathtub to a walk-in shower even if your home has an unpermitted garage conversion, but the bathroom work must stand on its own permits and meet current code. The bathroom remodel gets inspected independently. The illegal conversion doesn’t block your bathroom permit, though city inspectors may note the conversion if it’s visible during inspection. That’s a conversation worth having with your contractor before work begins so you understand the risk. We’ll give you the straight answer during the estimate.
Your Bathroom Remodel, Priced Before You Commit

We recently remodeled a 1947 bungalow bathroom on State Street south of Firestone, where the original slab sat only inches above the seasonal water table. Because the home was in a FEMA flood zone, we elevated the shower pan by two inches and installed a flood-rated drain assembly, then coordinated the floodplain permit and inspection sign-off before we closed the walls. That saved the homeowner a potential insurance denial later, and it cost less than the rework would have if the inspector had flagged it after tile was set.
That’s the kind of detail work South Gate bathrooms require, and it’s the kind of work we plan for before we ever pick up a hammer. Trevor Nash signs the price sheet. The Kingswell Guarantee backs the work in writing. The 365-Day Done Right Promise means we return and repair at no charge if anything fails inside a year. And if a repair fails a second time, the follow-up visit is free. No service call, no re-inspection fee.
