We know Lomita’s homes because we work on them every week as a General Contractor in Lomita. The 1940s and 1950s single-story houses here have a particular set of bones: raised wood foundations, original framing that has settled, and plumbing rough-ins that were never meant for today’s fixtures. That changes how we bid, how we schedule, and how we protect your home while the work is underway. If you are off Narbonne, up near Lumley Drive, or over by Eshelman Avenue, we have likely been on a job within a few blocks of you recently.
Why Mason Remodeling Co Torrance Is Lomita’s Preferred Bathroom Remodeling Company

Homeowners in Lomita call us because we put everything in writing before a single tool comes off the truck. That means a fixed price, a written scope of work, and a named crew you will recognize at the door. No verbal estimates that grow. No surprise invoices at the end.
Every technician who steps onto a Lomita property has passed a background check and identity verification under the Threshold Standard. Before your project starts, you receive the name and photo of each crew member who will be inside your home. On the day of work, every person at your door wears a clean uniform and carries a photo ID badge. We know that opening your door to a remodeler is a safety decision, not a formality. Isaac Pruett, who leads our team, built that standard into how we operate from day one.
Our bathrooms are covered by a written guarantee with plain-language terms. If something is not right within 365 days of completion, we return and make it right at no charge. No dispute process. No conditions. That applies across Bathroom Remodeling work of every size.
Styles & brands we work with







Walk In Shower in Lomita
A walk in shower installed in a Lomita home typically costs $4,500 to $12,000 depending on whether we are replacing a tub, moving a drain, adding a frameless glass enclosure, or starting from an empty corner. In the 1950s homes we see across Lomita, the decision usually comes down to mobility: the original tub is a step-over risk, and the homeowner wants a zero-threshold entry that works for aging in place.
One thing we flag on every walk in shower quote: the floor under that old tub. In Lomita’s marine-layer climate, subfloor rot is common. We check for it before we give you a number, because the last thing anyone wants is a beautiful new tile shower sitting on a floor that flexes.
Curbless Entry on Raised Foundations
Curbless showers on a raised wood foundation require the same structural attention as any other remodel: we confirm the joists can handle the recessed pan and the tile load. In some Lomita homes we have sistered joists or added blocking to get the floor solid enough for a truly flat entry. If the foundation has settled the way many 1950s homes here have, that work is part of the quote, not a change order later.
Converting a Tub to a Shower Without Moving the Drain
Most Lomita homeowners want to keep the existing drain location. It saves on plumbing costs and usually fits the original rough-in. We can often leave the toilet and sink positions alone and run the shower off the tub’s drain line, provided the slope works. We will tell you if it will not.
Bathroom Remodeling Companies in Lomita

Bathroom remodeling companies in Lomita are not all set up for the kind of small-lot, tight-access work this city requires. Your side yard might be five feet wide. Your neighbor’s garage might sit eighteen inches from your exterior wall. A crew that has never worked on a Lomita post-war home will fight the site the whole way. We plan for access before we quote.
A full bathroom remodel in Lomita runs $9,000 to $28,000. That range reflects what we actually see: a 1952 original bath with a sagging subfloor and non-conforming drain line costs more to do right than a cookie-cutter bathroom in newer construction, but it can still stay within a reasonable budget when the scope is clear from the start.
Working on Tight Lomita Lots
On a five-foot side yard, we stage materials in smaller loads and schedule debris removal around the access path. We do not pile anything against a neighbor’s fence. Lomita code enforcement pays attention to construction sites, and a dumpster that blocks a shared driveway or a debris pile that drifts onto the property line will get cited. Our crews keep the site tight and clean because it is less expensive for you and better for the street.
Permits and Non-Conforming Additions
Many Lomita homes have unpermitted second bathrooms, converted garage spaces, or “mother-in-law” additions with plumbing that was never inspected. If you want to remodel one of those spaces, the permit path is different. We will tell you what has to be brought up to code, what the city will require, and what it will cost. Mason Remodeling Co Torrance handles permit drawings and city submissions as part of the job, not as an afterthought.
Trusted Brands We Service in Lomita
We install fixtures and finishes from the manufacturers homeowners in Lomita actually ask for by name: Kohler and Moen for faucets and shower systems, Cambria and Caesarstone for vanity tops, and KraftMaid and Wellborn for cabinetry. For window work tied to bathroom remodels where natural light matters, we source from CWS and ECO Window Systems. Rough-in and hardware we keep local and stocked for quick turnaround on the Lomita jobs we have scheduled, which means fewer days where your bathroom is just an empty room.
Common Bathroom Remodeling Problems We See in Lomita Homes
- Hidden dry rot from marine layer moisture. Lomita’s cool, damp air works its way into subfloors and wall plates over decades. A contractor who skips moisture checks gets callbacks for cracked tile and soft floors within two years. We check before we bid.
- Non-conforming plumbing from converted garages. Many Lomita homes have bathroom additions that were never permitted. The drain lines, venting, and electrical often fail today’s code. Remodeling those spaces means bringing the whole rough-in up to standard, and our quotes account for that from day one.
- Narrow side-yard access that stalls other crews. If the dumpster does not fit and the lift does not fit, the job turns into a mess. We plan smaller material loads, scheduled haul-offs, and a daily cleanup routine that keeps Lomita job sites from becoming code enforcement targets.
- Settled framing that throws off tile lines. A 1950s raised foundation that has moved an inch means your new tile will telegraph that movement if the substrate is not corrected first. We level, sister joists, and add blocking where needed so the shower pan sits flat and the wall tile stays straight.

FAQs About Bathroom Remodeling in Lomita
We treat shared-wall plumbing as a party-wall job: we notify the neighbor in writing before any work touches a common wall, we keep the demolition controlled, and we schedule noisy work inside Lomita’s allowed construction hours. The plumbing itself is rerouted inside your unit to avoid cutting into shared framing. Call (424) 337-6939 and we will look at the wall layout before we quote it.
Yes, and we do this regularly in Lomita, where converted garages and “mother-in-law” additions are common. The remodel becomes a two-phase job: we bring the existing plumbing, electrical, and ventilation up to code as part of the permit drawings, then build the new bathroom. That usually adds cost and time, and our written quote will separate the code-compliance work from the finish work so you are not guessing. We pull the permits and schedule the inspections for you.
Lomita bathroom permits are generally modest in cost, though the total depends on whether structural changes, sewer line work, or non-conforming addition legalization is involved. Plan on a few weeks for plan check, longer if the Lumley Drive historic overlay area applies to your home and the drawings need an extra review pass. We include permit fees as a line item in your quote. Call us for an exact number once we know the scope.
In most Lomita homes, yes. A standard tub drain sits at one end of a 5-foot opening, and we can typically reuse that drain location for a 60-inch shower pan or a tiled shower base. We will confirm the slope is workable before we bid. If the drain movement is required, we will tell you the added cost up front. Call (424) 337-6939 for a written quote on your specific bathroom.
We run our Lomita job sites so the answer is usually no. We stage materials in the driveway or the side yard, and we schedule dumpsters and material deliveries to keep the street clear. On tight lots we do smaller deliveries more often rather than dropping a full load at once. We also follow Lomita’s construction work-hour rules. If a neighbor raises a concern, we fix it the same day.
