Fast, Reliable Bathroom Remodeling Across Irvine
Bathroom remodeling in Irvine typically runs $22,000 – $48,000 for a full gut and rebuild, with hall baths on the lower end and master suites with custom tile and glass on the higher end. Most Irvine jobs take 3 – 6 weeks once demo starts, and the scope almost always grows once we open the walls. That’s the part no other contractor mentions upfront. Call (877) 801-4497 and we’ll walk you through exactly what your village home is likely to turn up before you sign anything.
Why Fullerton ADU Builders Is Irvine’s Preferred Bathroom Remodeling Company
We’ve remodeled bathrooms in Woodbridge, Deerfield, Northwood, and the newer product at Great Park, and the pattern is consistent: original builder-grade work from the era the house was built, plus an HOA architectural committee that has opinions about your vent and window placement. Glen Pacheco built this company around a simple rule: inspection first, written allowances second, and no work starts until you approve the real number in writing. Homeowners in the 92602, 92603, and 92697 ZIP codes deal with a layer of design review that neighboring cities just don’t have, and we handle that coordination as part of the job. Our Bathroom Remodeling team has walked enough Irvine village approvals to anticipate what gets flagged before the committee sees the plans.
We’re not a general contractor who happens to do bathrooms. We’re a specialist that bundles ADU construction with kitchen and bath remodeling, which means we think in terms of water supply, drain lines, and structural upgrades the way a production remodeler doesn’t. When we’re working in an Irvine stucco-and-tile home, we already know what the plumbing stack looks like behind that 1970s greenboard.
Our Bathroom Remodeling Services in Irvine
Inspection-First Scope and Written Allowances
Before any demo hammer swings in your Irvine home, we open a small access panel or pull the escutcheon plates and run a scope camera down the supply lines and drain assembly. If we see polybutylene-era piping, original copper with visible corrosion, or a shower pan that sits flat on the subfloor, we write those as itemized allowances with real dollar figures, not open-ended contingencies. You approve the allowance before the wall comes down. If we don’t use all of it, you don’t pay it. That’s how a Woodbridge homeowner avoids the $9,000 surprise.
Waterproofing and Shower-Pan Rebuild to Current Code
Irvine’s planned-community homes from the 1960s through the 2000s were built before current shower waterproofing standards existed. Most original pans we pull in Deerfield and Northwood have no pre-slope, no membrane, and tile bedded directly onto greenboard that’s been wicking water for decades. We rebuild from the subfloor up: pre-slope, bonded waterproofing membrane, flood test, then tile. This isn’t an upgrade; it’s what the building code in Orange County now requires once that area is opened.
Permit and Village HOA Architectural Review Coordination
Here’s what makes Bathroom Remodeling in Irvine different from Tustin or Santa Ana: the city of Irvine plan check can approve your permit, and then your village’s architectural committee can still reject the window facing the rear yard, question the vent termination, or ask you to match the stucco color to the neighbor’s wall. We pull the city permit and package the HOA submission with drawings that speak the committee’s language. In Great Park, that means one set of rules. In Woodbridge, a slightly different set. We don’t guess. We walk it through.
Full Gut Renovations and Cosmetic Refreshes
Some Irvine homeowners want a full master-bath tear-out with new plumbing, linear drains, and curbless entry. Others want the hall bath re-tiled and re-fitted without moving the footprint. Both jobs get the same reality check on what’s behind the walls, because a 1970s copper drain in the 92603 area behaves the same way whether you’re spending $12,000 or $45,000. We scope what’s actually there.

Trusted Brands We Service in Irvine
We specify what works in Irvine’s climate and housing stock. James Hardie fiber cement shows up more on our exterior ADU work, but it tells you how we think about moisture and durability, and that carries into bath remodels where we spec Schluter waterproofing systems, Wedi panels, and Delta or Kohler fixtures depending on your budget. For prefab ADU projects on the same property that need a bathroom, we’ve worked with Tuff Shed, Abodu, and Cover units, which means we understand how a compact factory-built bath handles plumbing rough-ins differently than a site-built one. One contractor for your ADU and your home, whether the bathroom is inside the house or inside the new unit in the rear yard.
Common Bathroom Remodeling Problems We See in Irvine Homes
- Copper pinhole leaks behind the wall. In Woodbridge and Deerfield homes from the 1970s and early 1980s, the original copper supply lines have been carrying hard water for 50 years. A pinhole that’s been weeping for months is often invisible until demo opens the wall cavity, and then it turns a tile refresh into a re-pipe.
- Failed shower pans with no pre-slope. Original Irvine builder shower pans frequently sit directly on the subfloor with no slope to the drain. Water pools, wicks into the framing, and by the time we pull the tile, the studs behind the pan are soft enough to take a screwdriver by hand.
- Greenboard behind original tile. Before modern waterproofing membranes existed, builders used water-resistant drywall called greenboard behind shower tile. In Irvine’s mild, dry climate it lasts longer than you’d expect, but Santa Ana wind season pushes dust and dry air through cracks, and decades of steam eventually win. We find it in most original hall baths we open.
- Permit-triggered GFCI and venting upgrades. Irvine requires bathroom circuits to meet current GFCI protection once the walls are open, and exhaust fans must vent to the exterior, not into the attic. Homeowners who skip the permit to save time end up with a finished bath that fails a resale inspection and a village HOA that can flag the vent location after the fact.
Pricing for Bathroom Remodeling in Irvine, CA
A cosmetic refresh that keeps the existing footprint and plumbing locations runs $9,000 – $15,000 in Irvine. A full hall-bath gut with new pan, waterproofing, tile, vanity, and fixtures sits between $22,000 and $32,000. Master bathrooms with custom glass, linear drains, and relocated plumbing land in the $35,000 – $48,000 range. What moves the number is what demo finds: a re-pipe adds $3,500 – $7,000, rotted framing repair adds $1,800 – $4,500, and a village-mandated window or vent change can add $800 – $2,000. We write these as itemized allowances before the walls come down, so the final figure is a decision, not a surprise. Call (877) 801-4497 and we’ll put a real number on your specific bath, free.

FAQs – Bathroom Remodeling in Irvine
Because original builder-grade plumbing and waterproofing from the 1960s – 2000s fails the moment it’s exposed, and most contractors don’t price it upfront. In Irvine’s planned-community homes, the most common post-demo discoveries are failed shower pans without pre-slopes, rotted studs behind greenboard, and pinhole leaks in 50-year-old copper. We solve this with a scope-camera inspection before demo and itemized allowances with hard dollar figures, so the quote moves because you approved a specific line item, not because we found something we should have predicted. Call (877) 801-4497 for an exact quote – estimates are free.
Yes, any remodel that touches plumbing, electrical, or framing in Irvine requires a city permit, and opening the walls triggers current code: GFCI protection on bath circuits, exhaust venting to the exterior, and waterproofing to current shower-pan standards. If you change the window size or location, that also goes through the village HOA architectural committee. We pull the permit and handle the HOA submittal as part of the job. Call us for a breakdown of what your specific bath will trigger.
Yes. In Irvine, city plan check and village architectural review are two separate approvals, and the HOA can reject or delay a window, vent, or exterior change even after the city stamp is on the plans. In Woodbridge, a rear-facing window change triggered village review that added three weeks to one of our jobs; in Northwood, a vent relocation passed without comment. We calendar the HOA review into the schedule from day one. Call (877) 801-4497 to talk through what your village requires.
In our experience, a 1970s Woodbridge bath demo typically turns up a shower pan laid flat on the subfloor with no pre-slope, greenboard behind the tile that’s been wicking moisture for decades, and copper supply lines with visible corrosion or an active pinhole. We plan for all three in the original scope and write them as allowances. The only real variable is how far the rot goes once the pan comes out. Call us to schedule a pre-demo inspection and we’ll tell you what we expect before the first tile comes off.
We write a framing repair allowance into the contract before demo starts, with a defined scope and a defined price per stud or per linear foot. When the wall comes open in your Irvine home and the studs behind the shower are shot, we take photos, show you the exact removal area, get your written approval on the adjusted number, and proceed the same day. No work begins on a changed scope until you’ve signed off on the dollar figure. That’s the only way we build. Call (877) 801-4497 and we’ll put that in writing for your job.
If you’re weighing a bathroom remodel in Irvine against adding an ADU with its own bath, we can price both paths honestly. Our scope covers Bathroom Remodeling alongside ADU construction, kitchen work, and site-built or prefab delivery, so you’re not juggling two contractors for one property. One phone call, one inspection, one set of allowances. Call (877) 801-4497 today to schedule your free estimate.
