Bathroom remodeling in Irvine typically runs $9,000 – $28,000 for a full remodel, with smaller baths landing between $5,000 and $12,000. The number moves based on what’s inside your walls, not just what’s on top of them. Penhallow Remodeling Orange County works across Irvine weekly, from Woodbridge to Northwood to the Great Park neighborhoods. We schedule from our Los Angeles office, and our background-checked, uniformed crews serve Irvine homes directly. If you’re planning a remodel, call (424) 541-1701 to talk through your scope and get a written price before any work starts.
Why Penhallow Remodeling Orange County Is Irvine’s Preferred Bathroom Remodeling Company

Irvine homeowners call us because we put the price and the guarantee in writing before a single tile is pulled. The Kingswell standard has been our operating rule since 2004: a written price up front, a defined arrival window, a clean job site, and a written guarantee on every project. That guarantee is the 365-Day Done Right Promise. If the work fails inside that year, we come back and fix it at no charge. No service call, no re-inspection fee.
Trevor Nash runs our Orange County operation and holds every project to that standard. Homeowners in Irvine’s master-planned villages regularly tell us the same thing: they’ve been burned by a verbal estimate that changed after demo day. With us, the number on day one is the number on the invoice. A live person answers the phone 24/7, so when you call (424) 541-1701, you speak to a human, not a voicemail maze.
Irvine’s HOA and city code landscape is unforgiving with remodel work. We know the local approval processes for interior renovations across the city’s villages, and we build that knowledge into every bid. That matters when a 1970s Woodbridge bath hides aluminum wiring that won’t pass a rough-in inspection.
Styles & brands we work with







Bathroom Remodeling Companies in Irvine
Bathroom Remodeling Companies in Irvine range from one-truck operations to full design-build firms, and choosing among them comes down to how each handles the city’s specific housing stock. A full bathroom remodel in Irvine means removing the existing fixtures, opening walls to inspect framing and plumbing, replacing or repairing substrate, and rebuilding to current code. The work regularly surfaces aluminum wiring and polybutylene supply lines in homes built before the mid-1990s, which pushes scope beyond the initial quote. Full remodels run $9,000 – $28,000 in this market.
Written Scope, Not Verbal Guesswork
We write an allowance into every Irvine contract for what gets found when the wet wall opens. That means you approve a change order in writing before we spend a dollar on unexpected work. The alternative is the mid-project surprise that so many Irvine homeowners have already endured once.
Permits and Inspections
We pull permits for interior bathroom remodels in Irvine and schedule the rough-in and final inspections ourselves. The city’s inspectors know what to look for, and so do we. That alignment keeps your project moving instead of stalling at a failed inspection with drywall already ordered.
Bathroom Renovation in Irvine

Bathroom Renovation in Irvine often means refreshing a bathroom in a home that’s 30 to 50 years old, not just swapping a vanity and paint. Original 1970s and 1980s bathrooms in villages like Woodbridge and University Park carry builder-grade materials, fiberglass tub surrounds, and plumbing that predates current PEX and copper standards. A renovation here involves replacing those systems while keeping the footprint the HOA and city have already approved. Expect $9,000 – $28,000 for a full renovation, and $5,000 – $12,000 for a small bath.
Waterproofing and Substrate
We install cement board substrate (the moisture-resistant layer behind your tile) and waterproof membranes to current code, not to what passed in 1978. Irvine’s dry climate doesn’t excuse a failed shower pan. When our crew opens an original bath and finds water-damaged subfloor under the tile, we photograph it, price the repair as a written change order, and get your approval before proceeding.
Fixture and Finish Levels
Your finish selections drive a meaningful chunk of the budget. We install Kohler and Moen fixtures, Silestone and Caesarstone tops where a vanity calls for it. The labor is the same. The material line item is where your taste sets the price.
Trusted Brands We Service in Irvine
Irvine homeowners care about what goes into the room, not just how it looks. We stock a working inventory of Kohler and Moen fixtures locally, and we source Silestone and Caesarstone vanity tops for Irvine jobs on a 7-to-10 day order cycle from regional suppliers. When a fixture fails inside the first year, we carry the replacement under our 365-Day Done Right Promise and get it swapped quickly. You won’t wait weeks for a part while a brand warranty works through a national support line. We handle it, because the guarantee is ours too.

AfterCommon Bathroom Remodeling Problems We See in Irvine Homes
- Aluminum wiring hidden behind original drywall. Homes built in Irvine’s older villages before the mid-1970s often ran aluminum branch circuits to bath lighting and outlets. Once a wall is open, the rough-in inspection flags it, and a repair becomes a rewire.
- Polybutylene supply lines in the wet wall. Gray polybutylene pipe was common into the early 1990s. It gets brittle with age, and inspectors won’t sign off with it exposed. Replacement to copper or PEX is standard on our Irvine remodels.
- Failed shower pan waterproofing under original tile. Builders in the 1970s and 1980s often skipped a proper membrane. By the time tile grout cracks, the subfloor underneath has been absorbing moisture for years. We open it, replace the substrate, and waterproof to current code.
- HOA design-review friction on interior changes. Most Irvine interior bath remodels don’t need HOA approval if the footprint doesn’t change, but villages do enforce noise windows and contractor access rules. We know which ones and plan the schedule around them.

Opening a primary bath in a Woodbridge two-story, our crew found the original 1970s aluminum branch circuits feeding the vanity lights and a polybutylene riser behind the shower valve. Since the rough-in inspection wouldn’t sign off with aluminum or PB exposed, we rewired the bath circuit and repiped the wet wall to copper, wrote the delta as a change order, and kept the homeowner’s final draw schedule matching the approved scope. That’s how we handle every Irvine remodel: inspection first, allowances written into the contract, and any surprise priced and approved in writing before we proceed.

FAQs About Bathroom Remodeling in Irvine
Aluminum branch wiring and polybutylene supply lines are the two most common findings, and both fail a rough-in inspection. A 1970s Woodbridge bath will typically need the bath circuit rewired to copper and the wet wall repiped before the city signs off. We include an allowance for exactly this in every Irvine contract, so the correction is a written change order, not a surprise.
Yes. Irvine requires permits for interior bathroom remodels that involve opening walls, moving plumbing, or replacing electrical circuits, even if the footprint stays the same. We pull the permit, schedule the inspections, and build the inspection timeline into your schedule. Call (424) 541-1701 and we’ll walk you through what your specific scope triggers.
We photograph it, write up the repair scope and cost as a change order, and get your written approval before doing the work. Original 1970s and 1980s Irvine bathrooms frequently have rotted subfloor under the shower pan and around the toilet flange because builders skipped proper waterproofing. The repair is straightforward, but you’ll see the number before we spend it.
Because the home’s age dictates what inspectors will require once the framing is exposed. Aluminum wiring, polybutylene pipe, undersized joists, and failed waterproofing are all common in Irvine’s original villages. A contractor who doesn’t price an allowance for those findings is handing you a lowball that will change at the drywall stage. Our quotes include a written allowance and a defined change-order process.
For most interior remodels where the footprint and exterior walls don’t change, the HOA’s role is limited to construction hours, noise rules, and contractor access requirements. Some villages require notification before major interior work begins, even if no design review is needed. We know the process for the major Irvine villages and factor it into the schedule. Call (424) 541-1701 and we’ll confirm what your specific community requires.
