Fast, Reliable Bathroom Remodeling Across Irvine
A bathroom remodel in Irvine typically costs between $18,000 and $45,000 for a full gut-and-replace, with smaller refreshes starting around $9,000 and premium master baths in newer Great Park homes running $60,000 or more. Most projects we take on in Irvine run four to seven weeks from demo to final inspection, depending on whether we find aging plumbing behind the tile. Manzanita ADU Builders works across every Irvine village, from Woodbridge to Quail Hill to Portola Springs, and we’re familiar with the HOA approval realities that can stall a remodel before it starts.

Why Manzanita ADU Builders Is Irvine’s Preferred Bathroom Remodeling Company
Bathroom remodeling in Irvine is different from bathroom remodeling almost anywhere else in Orange County. This is a master-planned city. Nearly every home sits in an HOA-governed village with an architectural committee that reviews exterior changes before, during, or after the interior work starts. A bathroom remodel that changes a window size, relocates a vent, or patches exterior stucco can get held up by the village committee even after the city of Irvine issues permits. We know this because we’ve built ADUs, additions, garages, kitchens, and baths across Irvine’s planned villages for years. We sequence the HOA review before demo, not after.
Homeowners across Irvine call us because our work as Bathroom Remodeling contractors is grounded in whole-property thinking. We’re not just swapping tile. We’re looking at the supply lines behind the wall, the drain run under the slab, and the venting through the roof. In 1970s-80s villages like Woodbridge and Northwood, that’s where the real scope lives. Our team, led by Noel Carrasco, walks every Irvine client through exactly what we might find before we put a single tool to the wall.
We’re built around single-contractor accountability. The same crew that frames an attached ADU addition also roughs in its bathroom. No handoff. No blame loop between a sub and a GC. When you call (833) 467-4140, you talk to the team that actually does the work.
Our Bathroom Remodeling Services in Irvine
Garage Conversion Bathroom Rough-In
Garage conversions are one of the most common ways Irvine homeowners add a rentable unit or guest suite, especially in older villages where detached ADUs don’t fit under the CC&Rs and lot lines. A bathroom rough-in for a garage conversion in Irvine runs $8,000 to $18,000, depending on slab conditions. That includes new drain lines, supply piping, venting, and the underground plumbing work before walls go up. In Woodbridge especially, we regularly see 1970s slab garages with no existing plumbing stub, so we cut a section of the slab and run new ABS drains to the main line. HOA approval is usually required before we touch the exterior wall or garage door, and we manage that paperwork in sequence with city permits.
Interior Bathroom Remodel with Re-Pipe
A full interior remodel in an Irvine tract home from the 1970s or 80s almost always includes some level of re-pipe. The original copper supply lines in these homes are at or past their realistic service life, and the thin-wall drains or cast-iron segments behind the tub are frequently weeping. A complete hall bathroom remodel with re-pipe in Irvine runs $20,000 to $38,000. Master baths run higher. We replace old copper or polybutylene with PEX, re-set PVC or ABS drains, and upgrade the vent stack if it’s undersized. This isn’t a change order surprise. We price for it up front based on the home’s age and the village.
Attached Addition Bathroom Build-Out
For homeowners adding a ground-floor primary suite or expanding a second story, the bathroom build-out is one of the most permitting-sensitive parts of the job. In Irvine, an attached addition bathroom needs its own plumbing, electrical, and structural review. Cost for a new addition bath runs $25,000 to $55,000 depending on fixtures and square footage. We handle the entire build from foundation to finish, including the exterior James Hardie cladding so the addition matches the existing stucco-and-tile character of the home rather than looking bolted on.
Full Bathroom Remodeling in Irvine Villages
We work in every major Irvine village: Woodbridge, Northwood, Turtle Rock, Rancho San Joaquin, Quail Hill, Great Park, and Portola Springs. Each has slightly different HOA rules. The older villages tend to have stricter architectural committee oversight on exterior changes. Great Park and newer 92618/92602 homes are more ADU-ready and less likely to need a full re-pipe, but we still check. Our bathroom projects in Irvine average four to seven weeks, and we keep a clean, contained site whether we’re inside a condo courtyard or working on a street with no driveway staging.

Trusted Brands We Service in Irvine
We install and work with a range of bathroom brands and finish packages, and we match the product to the home’s style. For Irvine’s Mediterranean and Spanish-tract housing stock, we frequently use matte porcelain in warm earth tones, cast-stone vanities, and brushed brass or black fixtures. For modern Great Park and 92618 homes, clients lean toward larger-format porcelain slabs, frameless glass, and wall-hung vanities. We also stock local parts for fast turnaround, especially common valves, PEX fittings, and drain sets, so an Irvine job doesn’t stall waiting on a backorder. Manzanita ADU Builders is manufacturer-agnostic across the board. You pick the look. We bring the build quality.
Common Bathroom Remodeling Problems We See in Irvine Homes
- Aging supply and drain lines in 1970s-80s villages. Woodbridge, Northwood, and Rancho San Joaquin homes were built with copper and cast iron that’s now 40 to 50 years old. We regularly find weeping cast-iron bends and undersized copper stubs once the tile comes off. That drives realistic scope, not lowball quotes.
- HOA architectural committee review stalling the job. In Irvine, an exterior bathroom change such as a new window, a relocated vent, or a stucco patch can require village committee signoff even after city permits are in hand. We sequence that review before demo so the remodel never gets halted mid-project.
- Tight lots with no driveway staging. Many Irvine courtyard homes and street-facing tracts have no usable driveway for a dumpster or material drop. Dumpster placement in the street often requires city permit and HOA notice, and material handling costs more. We price access from the start, not as an add-on.
- Shared walls and party-wall notice requirements. In Irvine townhome and condo villages, bathrooms often share a wall with the neighbor’s garage or hallway. We post 48-hour courteous notice before any hammering on shared walls and keep noise within city work hours. It protects the project and the neighbor relationship.
Pricing for Bathroom Remodeling in Irvine, CA
A cosmetic bathroom refresh in Irvine, meaning new vanity, fixture swap, paint, and re-glazed tub, typically runs $8,000 to $15,000. A full gut remodel with re-pipe, new tile, wet-area waterproofing, and fixture relocation runs $18,000 to $45,000. Master bathrooms in Great Park or newer 92618 homes with premium finishes run $45,000 to $65,000 or more. The single biggest variable in Irvine is what’s behind the walls. A 1970s Woodbridge bathroom with original copper and cast iron almost always costs more than a 2015 Great Park bath. We quote from what we can see and price the likely re-pipe in the estimate rather than surprising you later. Call (833) 467-4140 for a free itemized estimate.

FAQs – Bathroom Remodeling in Irvine
For interior-only bathroom work, you generally do not need HOA or village architectural committee approval in Woodbridge, Northwood, or most other Irvine villages. Approval is required only when the remodel touches the exterior, such as changing a window size, relocating a vent, patching stucco, or altering any exterior finish. Even then, the village committee review is separate from the city of Irvine permit. We check the specific CC&Rs for your village before demo starts. Call (833) 467-4140 to have us verify your property’s requirements.
Yes. In 1970s and 80s Irvine villages like Woodbridge, Northwood, and Rancho San Joaquin, the original copper supply lines and cast-iron or thin-wall drains are 40 to 50 years old. A cosmetic remodel frequently becomes a re-pipe plus drain rework once the tile comes off. We price the likely scope up front based on the home’s age and village, so the re-pipe is not a surprise change order. Call (833) 467-4140 for a site visit and straight numbers.
A tight Irvine lot with no driveway staging adds cost to material handling, debris hauling, and dumpster placement. Street placement of a dumpster often requires a city permit and HOA notice, and every piece of material must be carried farther from the street. We include access cost in our initial quote, not as a mid-project change order. Call (833) 467-4140 to schedule a free estimate that accounts for your site.
Yes. We regularly remodel bathrooms that share a party wall in Irvine townhome and condo villages. We post 48-hour courtesy notice before any hammering on the shared wall, stay within city work-hour rules, and inspect the wall framing and plumbing before we close it back up. Party-wall work is standard for us. Call (833) 467-4140 to discuss your townhome remodel.
Yes, a garage-conversion ADU bathroom typically needs its own plumbing, electrical, and sometimes mechanical permits, issued as part of the ADU permit set but tracked separately by the city of Irvine. The HOA or village architectural committee also reviews the garage door and exterior changes. We pull and manage both permit paths so nothing holds up the final inspection. Call (833) 467-4140 to get your ADU bathroom scoped and priced.
