Fast, Reliable Bathroom Remodeling Across Wilmington
A full bathroom remodel in Wilmington typically runs $9,000-$28,000, with most projects taking three to six weeks from permit to final inspection. Our crews serve Wilmington directly, with scheduling coordinated from our Los Angeles office and dispatch to neighborhoods from the Harbor Freeway corridor down to the port-adjacent blocks near C Street. We’ve worked the post-WWII stucco bungalows off Watson Avenue, the duplexes near Avalon Boulevard, and the smaller homes around Banning Park - enough to know that opening walls in a 1950s Wilmington bathroom almost always reveals something the homeowner didn’t expect.

Why Rowan Construction Group Long Beach Is Wilmington’s Preferred Bathroom Remodeling Company
We’ve completed bathroom remodels across Wilmington’s 90744 zip and the surrounding blocks, and our customers here leave reviews that mention the same thing: we showed them the photos, named the price in writing, and stuck to it. Our Bathroom Remodeling team carries a documented photo record on every visit - standard, not an upgrade - so a homeowner on L Street or Pacific Coast Highway can see exactly what we found behind their drywall before we quote the repair.
Calls are answered by a live person 24/7, and our background-checked, uniformed technicians arrive with the permit knowledge specific to Wilmington’s LADBS jurisdiction. That matters here more than in most LA neighborhoods. Wilmington sits atop the Wilmington Oil Field, and most of the residential area falls inside methane zone designations that add inspection steps other cities don’t have. Out-of-area contractors miss this regularly. We don’t.
Under Clause 1 of The Haven Standard, the price is written before anyone starts. Under the 365-Day Done Right Promise, if it’s not done right, we make it right - backed by terms you can read, not a handshake.
Our Bathroom Remodeling Services in Wilmington

Full Bathroom Remodeling
A full bathroom remodel in Wilmington means working within walls that were framed before modern waterproofing standards existed. In the 1940s and 1960s bungalows that dominate this area, we regularly find galvanized supply lines, ungrounded outlets, and framing that’s out of plumb from decades of slab settlement. Our process: inspect first, photograph everything, write allowances into the contract for likely hidden conditions, and price any surprise in writing before we touch it. The typical full remodel in Wilmington runs $9,000-$28,000.

Walk-In Showers & Shower Remodeling
Walk-in shower installation is our most requested bathroom upgrade in Wilmington, typically $4,500-$12,000. The challenge here isn’t the tile or the glass - it’s what happens when we cut the old pan out and find the slab-on-grade foundation cracked from oil-field subsidence, which is endemic in this neighborhood. A new shower pan set on an unlevel or deteriorated slab will fail at the drain no matter how skilled the installer. We check subfloor integrity before we quote the finish work, and if the slab needs repair, we write it as a priced change order with your signature before we proceed.

Tub-to-Shower Conversion
Tub-to-shower conversion in Wilmington runs $3,500-$10,000 and carries a specific local risk: the drain relocation or subfloor cutting required to fit a modern shower pan can trigger methane barrier and sub-slab venting requirements under LADBS codes tied to the oil field below. A contractor who doesn’t know Wilmington’s methane zone map can demolish your bathroom, install the pan, and fail inspection because the barrier was never specified. We pull permits with the methane condition checked from day one, and we price the barrier into the scope if ground-disturbing work is required.

Vanities, Tile & Fixtures
Vanity installation in Wilmington homes runs $800-$3,000, with tile and fixture packages scaled to the space. In older bathrooms with settled floors, we often find that the wall behind the vanity isn’t square to the floor anymore - a condition we document, then correct with shimming or minor framing before the cabinet goes in. We source Kohler and Toto fixtures through our fifty-plus brand network, which keeps the written quote honest rather than inflated.

Small Bathroom Remodels
Small bathroom remodels in Wilmington’s compact post-WWII layouts run $5,000-$12,000. These spaces demand precise measurement; an inch lost to poor layout planning means a door that hits the toilet or a shower door that can’t swing. We measure twice, cut once, and show you the layout on paper before we order material.

AfterTrusted Brands We Service in Wilmington
We maintain sourcing relationships across fifty-plus vetted brands, which means the numbers on your written quote reflect actual distributor pricing rather than padded allowances. For Bathroom Remodeling in Wilmington, we regularly specify Kohler and Toto fixtures for their corrosion resistance in salt-laden port air, and we source Cambria and Caesarstone countertops when the scope includes a vanity upgrade. For exterior hardscaping on projects that extend the bathroom footprint, we’ve used Techo-Bloc and Cambridge Pavers on Wilmington properties where the finish needs to withstand heavier diesel particulate exposure than cleaner coastal neighborhoods face. Stocking depth matters here: when a Wilmington homeowner chooses a specific tile lot or fixture finish, we can confirm availability before we write the price, not after you’ve signed.
Common Bathroom Remodeling Problems We See in Wilmington Homes

- Cracked slab-on-grade foundations from oil-field subsidence. The ground beneath Wilmington’s post-WWII bungalows has settled unevenly for decades. We open subfloors and find slabs that have dropped an inch or more at the drain location, which must be corrected before a new shower pan can drain properly.
- Corroded rough-in anchors and fasteners from salt-laden port air. Wilmington’s marine air carries salt inland from the Port of Los Angeles, plus refinery particulate that accelerates steel degradation. Framing anchors that look solid can crumble when we test them for new tile backer or a frameless glass enclosure.
- Undersized drain lines and ungrounded electrical. Bathrooms built in the 1940s-1960s used 1.5-inch drains and two-prong outlets. Modern codes require 2-inch shower drains and GFCI protection. We identify these upgrades during inspection and write them into the scope before demolition.
- Methane zone permit triggers on ground-disturbing work. Even a “simple” tub-to-shower conversion can require methane barrier installation if the work cuts into the slab. We check LADBS methane zone maps before we quote, not after we fail inspection.

FAQs - Bathroom Remodeling in Wilmington

Only if the permit scope includes ground-disturbing work like slab cutting, drain relocation, or new foundation elements in the methane zone. Most of Wilmington falls under LADBS methane zone designations tied to the Wilmington Oil Field, so a tub-to-shower conversion or walk-in shower install that cuts the slab will trigger barrier and passive venting requirements. We check the methane map before we quote and price the barrier into the scope when needed, so there’s no surprise after demolition. Call (424) 567-7009 for an exact quote - estimates are free.
It means we expect to find galvanized supply lines, ungrounded outlets, framing that has settled with the slab, and waterproofing that predates modern membrane standards. These conditions are fixable and common in Wilmington’s housing stock; we photograph them during inspection, write allowances into the contract, and price any necessary repairs in writing before we start. The age of the house doesn’t prevent a quality remodel - it just means the quote needs to account for what we’ll find. Call (424) 567-7009 for an exact quote - estimates are free.
The salt-laden marine air in Wilmington penetrates wall cavities through vents, soffits, and any gap in the envelope. We’ve found corroded steel connectors, degraded rebar, and rusted rough-in anchors behind intact tile in bathrooms a quarter-mile from the port. That corrosion weakens the structure that holds your new tile, glass, and fixtures. We inspect and replace degraded anchors as part of our standard prep - documented with photos - so the new installation has solid backing. Call (424) 567-7009 for an exact quote - estimates are free.
A typical full bathroom remodel in Wilmington runs $9,000-$28,000, with smaller projects at $5,000-$12,000. The largest cost drivers are: subfloor and slab repair if subsidence has caused cracking; plumbing and electrical upgrades to meet current code; methane barrier and venting if ground-disturbing work is required; and material selections for tile, fixtures, and countertops. Labor for skilled trades - waterproofing, tile setting, plumbing, electrical - makes up the balance. We itemize every line in the written quote. Call (424) 567-7009 for an exact quote - estimates are free.
Yes. We pull LADBS permits for all bathroom remodels in Wilmington, schedule inspections, and ensure sign-off before finish work proceeds. This includes methane zone compliance when required, which out-of-area contractors often miss. The permit cost is listed as a line item in your written quote, not buried in overhead. Call (424) 567-7009 for an exact quote - estimates are free.
We were called to a 1948 stucco bungalow off Watson Avenue in Wilmington, where the homeowner wanted a walk-in shower and a Kohler vanity swap; when our crew opened the subfloor, the slab-on-grade had cracked and settled from decades of oil-field subsidence, and the drain rough-in was undersized for a modern shower pan. Because the repair pushed into ground-disturbing work, we pulled the permit, added the methane barrier and passive venting riser to the plan, wrote the subfloor and framing repairs as a change order with the price approved in writing, and scheduled inspection sign-off before the tile went back down - final scope landed at $22,400, inside our Bathroom Remodel range.
Ready to start? Call (424) 567-7009 to schedule your free written estimate. We’ll inspect your bathroom, photograph existing conditions, and return a flat price with a written scope and written warranty - before any work begins.
