City of Industry Bathroom Remodel — 91744 / 91746
City of Industry bath remodels in the 91744 and 91746 residential pocket split into two buckets — the small 1950s to 1970s tract bath that has not been touched since the original build and the secondary bath added during a 1990s or 2000s addition that needs a current-code rebuild because the original work was permitted casually if at all. NP Line Design has been doing architectural work in LA since 2016 and holding a CSLB General B since 2023, with 200+ LA-region builds. City of Industry bath scope runs $25,000 to $76,000. Tier one — primary or hall bath full rebuild with new wet-area waterproofing to ANSI A118.10 spec, alcove tub, single vanity, comfort-height toilet, and full tile to ceiling on the wet wall — lands at $25,000 to $42,000. Tier two with separated shower, freestanding tub, double vanity, and custom tile lands at $46,000 to $62,000. Tier three with steam shower, heated floors, and luxury finish lands at $66,000 to $76,000. Bilingual project management. 24/7 response at 818-605-1388.
City of Industry Bath Pricing 2026 — Three Tiers
Tier one is the primary or hall bath full rebuild in a 91744 tract bungalow — 50 to 70 square feet, all new waterproofing to current ANSI A118.10 spec, alcove tub with a tile surround, single vanity with quartz counter, comfort-height toilet, recessed LED, exhaust fan ducted to exterior, and a GFCI-compliant electrical upgrade because the original 1960s wiring is dangerous behind the wall. Lands at $25,000 to $42,000. Tier two adds a separated walk-in shower with a glass enclosure, a freestanding soaking tub, a double vanity, and a custom tile pattern with feature wall. Lands at $46,000 to $62,000. Tier three is the luxury upgrade — steam shower with multi-zone controls, electric heated floor system, paneled mirror with integrated LED, programmable plumbing trim, and the full luxury finish package. Lands at $66,000 to $76,000. Each tier is line-item bid in English or Spanish.Wet-Area Waterproofing + The Hidden Damage Problem
Three out of five 91744 corridor bath openings find water damage behind the original tile. 1960s and 1970s tract bath construction used mortar-bed tile on a thin felt paper barrier — that system fails at the curb, behind the soap niche, and at the tub-wall junction within 25 to 35 years. The water sits in the subfloor framing and the rot is quiet until we open the wall. Our standard City of Industry bath scope includes selective demo of the original wet wall, framing inspection, subfloor inspection, and code-compliant replacement of any damaged material before we start the new install. The cost averages $2,800 on a corridor bath remodel and we carry it as a clearly identified line item, not buried in a contingency. The bilingual line-item presentation is important because the multi-generational households reviewing the bid want to see the number, discuss it together, and approve it together. Surprise-cost framing does not work in this corridor and it should not work anywhere.Permits, Inspections, and the LA County Workflow
Every City of Industry corridor bath remodel needs a combination permit through LA County Building and Safety covering plumbing, electrical, and minor structural. Plan check on EPIC-LA runs 7 to 14 days on a bath scope. We pre-stage every inspection — plumbing pressure test, electrical rough, framing, insulation, drywall close-up — to hit the inspector window without rescheduling. The 91744 and 91746 pockets sit in different inspection territory depending on the parcel; we confirm the inspector assignment before scheduling so the call lands with the right office. Bath remodels do not require the same level of structural review as kitchen wall-removals but they do require the wet-area envelope inspection, and the post-1970s tract product gets extra scrutiny on the plumbing rough because the original DWV layout had common defects. We have closed 24 City of Industry corridor bath permits since 2024 — every one passed final inspection without a corrective-work order.Why 91744 Picks an Architect-GC for Bath Work
The City of Industry bath remodel competition is mostly cash-bid tile setters who do good tile work and weak structural work. That does not pass current code. NP Line Design built up from an architectural practice in 2016 to the CSLB General B in 2023, with 200+ LA-region builds. The architect-GC stack on a bath remodel matters in the places that do not show up in finished-photo selection — the framing inspection behind the tile, the waterproofing membrane spec, the electrical rough that has to clear AFCI and GFCI requirements, and the documentation packet at closeout. We deliver bilingual line-item bids, cut sheets on every product, weekly photographic progress logs, a code reference sheet, and a one-year post-completion walk-through. Call 818-605-1388 in English or Spanish. Phone, text, web — 24/7 response.Bathroom Remodeling Questions Homeowners Ask About Bathroom Remodeling in Industry
What is a typical City of Industry bath remodel cost?
Primary or hall bath full rebuild in a 91744 tract home runs $25,000 to $42,000. With separated shower and freestanding tub, $46,000 to $62,000. Luxury tier with steam shower and heated floors, $66,000 to $76,000.

Will you find water damage when you open the wall?
Three out of five 91744 corridor bath openings find water damage behind the original tile. We carry the framing and subfloor repair as a clearly identified line item, averaging $2,800. No surprise billing.
Do you pull permits or work cash?
We pull and close every permit through LA County Building and Safety. Plan check 7 to 14 days on bath scope. Permit number on every invoice. No cash-bid bath work.
How long does the bath remodel take?
Three to five weeks for the same-footprint primary bath rebuild. Six to eight weeks for the tier-two separated-shower scope. Nine to eleven weeks for the luxury tier-three with steam and heated floors.
Can I keep using one bath if I have a second one?
Yes. We coordinate the schedule so families with a second functional bath can stay in the home. On single-bath homes we set up a temporary shower arrangement or coordinate a short relocation for the rough-in week.
What is the CSLB license?
CSLB General Building B-1, active since 2023. NP Line Design did architectural work in LA from 2016 forward; the GC came in 2023. License covers plumbing, electrical, structural, and finish on a bath scope.
Do you upgrade the electrical for code compliance?
Yes. Standard scope. The 1960s and 1970s 91744 wiring will not satisfy current AFCI and GFCI requirements. We rerun the bath branch circuits as a line item, typically $1,400 to $2,200.
