AfterFast, Reliable Bathroom Remodeling Across Agoura Hills
A full bathroom remodel in Agoura Hills typically runs $9,000 to $28,000, with walk-in shower installations starting around $4,500 and tub-to-shower conversions landing between $3,500 and $10,000. Those numbers hold until we open the walls. Agoura Hills homes built in the 1970s through the 1990s have a way of hiding galvanized pipes, undersized framing, and failed waterproofing behind perfectly innocent tile, and that’s where the real cost conversation begins.
We’ve worked these hillside tracts long enough to know what’s behind the drywall before the first swing of a hammer. Barrett & Sons Construction is owner-operated by Tom Barrett, and when you call, you get a live person, not a voicemail box. Call (877) 610-1318 and we’ll walk you through exactly what your Agoura Hills bathroom needs.
Why Barrett & Sons Construction Is Agoura Hills’s Preferred Bathroom Remodeling Company
Tom Barrett put his name on the truck in 1998, and he’s never taken it off. His sons run crews on job sites across Agoura Hills, Oak Park, and the Las Virgenes Valley, and Tom himself shows up at plan-check and inspection. That matters in this city more than most places. The building department here knows which contractors pull permits and which ones try to skip them, and we’ve made a point of being the former for nearly three decades.
Agoura Hills sits in a Very High Fire Hazard Severity Zone, and after the Woolsey Fire took hundreds of homes in 2018, the permit reviewers here read every plan through a Chapter 7A lens. A contractor who doesn’t know those standards will get bounced at plan-check and leave you holding a demo’d bathroom and a stop-work order. We don’t get bounced. We write scope in writing, allowances in writing, and change orders in writing, and every eligible job gets permits pulled and inspections signed. Ask anyone on your street in the 91301 or 91376 zip code, or look up the license number yourself.
We’ve fielded calls from homeowners near Agoura High School, Old Agoura, and the Liberty Canyon corridor who got burned by a national outfit that quoted one price on the phone and handed them a different bill after demo. That’s not how we run a job. The price changes only when the wall opens and we both see what’s in there, and even then, you approve the number in writing before we spend a dollar.
Our Bathroom Remodeling Services in Agoura Hills
Every Bathroom Remodeling job in Agoura Hills starts with an inspection, not a sales pitch. We look at what’s behind the access panel, under the vanity, and above the ceiling before we ever hand you a number. Here’s what we handle most often in this city.
Full Bathroom Remodeling
The older ranch-style and Spanish-tile homes that line the hills above Kanan Road and Driver Avenue almost always need more than a fixture swap. We pull the room to studs, correct what’s been hiding, and rebuild to current code. If your home is post-Woolsey, we integrate the Chapter 7A envelope details without slowing the job, because we already know what the inspector wants to see.
Walk-In Showers & Shower Remodeling
We install a lot of walk-in showers in Agoura Hills for homeowners in their 50s and 60s who want to age in place without moving out of a paid-off hillside home. A curbless entry, properly sloped pan, and grab-bar blocking in the walls is not a luxury here, it’s a practical decision. We do the waterproofing the way the hillside demands: full-sheet membrane over a properly reinforced subfloor, because clay soils move and grout doesn’t.
Tub-to-Shower Conversion
Most Agoura Hills primary baths built before 1995 have a tub that nobody uses, taking up the square footage where a walk-in shower belongs. We convert tubs to showers in two to three weeks typically, and if the drain stack or venting needs reconfiguration after we open the floor, you’ll see it as a written change order before we proceed. No surprise invoices at the end. That’s the whole point.
Vanities, Tile & Fixtures
KraftMaid cabinetry, Cambria quartz, and fixtures you can look up by name. We don’t install mystery brands off a van. If you’re updating a vanity and tile in a smaller guest bath near Thousand Oaks Boulevard or Reyes Adobe, the permit path is faster, but we still pull it. The permit inspector works for you, not for me, and I appreciate the second set of eyes.

Trusted Brands We Service in Agoura Hills
We carry premium brands like Techo-Bloc and Cambridge Pavers on hardscape-adjacent work, and use Cambria quartz and KraftMaid cabinetry in bathrooms. If a brand belongs outdoors or in a kitchen, that’s where we use it. We don’t pad a bathroom quote with materials that don’t belong there. What we do stock and install are name-brand waterproofing systems, valves, and fixtures that any Agoura Hills homeowner can look up before signing. If we specify a brand, you’ll see it on the estimate, and we stand behind it with a 90-Day Done Right Promise written on the contract.
Common Bathroom Remodeling Problems We See in Agoura Hills Homes
Every hill town has its failure modes. Agoura Hills has a few we see over and over.
- Galvanized supply lines and aluminum branch wiring: Original to most 1970s and 1980s tract homes in the Las Virgenes Valley. Galvanized pipe narrows from the inside with rust, and aluminum wiring overheats at connection points. If a bathroom wall opens and we find either, the permit will require repair, not recommendation. We write those discoveries into the contract as allowances before demo starts, so the line item already exists and the price is already agreed.
- Failed shower pan waterproofing on hillside slabs: Expansive clay soils under Agoura Hills foundations don’t just drain. They expand and contract with moisture, and they move more on a hillside cut than on a flat lot. That movement translates through the subfloor and cracks grout lines, then water gets behind the tile. A rushed shower pan is a two-year leak in the making. We don’t rush it.
- Undersized framing from previous homeowner patches: We’ve found load-bearing walls with headers a previous owner cut into for a chase or niche and never reinforced. A bathroom on a slope already deals with shear stress. Opening a load-bearing wall that’s been compromised means we stop, write a re-framing scope, and show it to you before we touch the saw. It’s not a surprise. It’s a line item.
- Chapter 7A plan-check failures on vent and exhaust penetrations: In a Very High Fire Hazard Severity Zone, a bathroom fan that terminates through an exterior wall needs ember-resistant protection. A contractor who doesn’t know Chapter 7A will fail plan-check. We route penetrations to the interior side or through ember-rated vents from the start, because we’ve sat through enough Agoura Hills plan reviews to speak that language.
Pricing for Bathroom Remodeling in Agoura Hills, CA
Here’s what our recent Agoura Hills bathroom work has actually cost, in line-item ranges. These reflect the local market in 2025 and early 2026: higher-materials, four-code-inspection jobs on hillside lots, not the flat-valley pricing you’d see in Simi Valley.
| Scope of Work | Agoura Hills Price Range |
|---|---|
| Bathroom Remodel | $9,000 - $28,000 |
| Small Bathroom Remodel | $5,000 - $12,000 |
| Walk-In Shower Installation | $4,500 - $12,000 |
| Tub-to-Shower Conversion | $3,500 - $10,000 |
| Bathroom Vanity Installation | $800 - $3,000 |
What moves the number? Discovery inside the wall, which we covered above: galvanized repipe, re-framing, wiring upgrades. That’s why we write discovery allowances into the contract before demo. You know what a copper repipe costs if we find one. You’ve approved it in writing. There’s no bill at the end that wasn’t on paper first. Call (877) 610-1318 for a free estimate served with a straight face.

FAQs - Bathroom Remodeling in Agoura Hills
Yes. A post-Woolsey rebuild got its permits and inspections for the original construction, but any new bathroom work that touches plumbing, electrical, or structural elements requires a new permit in the City of Agoura Hills. The good news: the envelope is already Chapter 7A compliant, so we’re working inside an already-hardened shell, which often moves plan-check faster. Call (877) 610-1318 and we’ll walk you through what your specific project triggers.
Galvanized supply lines, aluminum branch wiring, and sometimes undersized framing from a homeowner patch. We’ve also seen original shower pans that were never fully waterproofed because the 1980s code didn’t demand what today’s inspector requires. We write allowance line items for each of these before we open the wall, so when we find them, you’re not surprised, and the job doesn’t stall. Call us for an exact quote, estimates are free.
It affects any penetration that crosses from the interior to the exterior: exhaust fan terminations, vent stacks, and sometimes plumbing vents. In a Very High Fire Hazard Severity Zone, those transitions have to use ember-resistant design details. Even a bathroom that feels entirely interior-adjacent, like a guest bath against an exterior wall near Morrison Ranch, can trigger a Chapter 7A review if the permit reviewer sees a wall penetration on the plan. We handle that coordination. It’s part of the job.
We write discovery allowances into the contract before demolition starts. Each allowance is a specific scope with a specific price range. If we open a wall and find a rotted sill plate or a galvanized supply run that has to go, we show you the written change order and you approve it before we proceed. That’s the Barrett & Sons way: every scope change on paper, before a nail moves. Call (877) 610-1318 and we’ll show you what an allowance line item actually looks like.
Yes. Hillside lots in Agoura Hills commonly sit on expansive clay soils that shift with seasonal moisture and seismic shear. That movement transfers through the subfloor and stresses grout joints, shower pan seams, and any waterproofing membrane installed without proper flex. Flat-valley homes in Thousand Oaks deal with less of this. We’ve opened hillside bathrooms where the previous shower pan was installed correctly for a flat slab and failed anyway. We build the pan for the hillside, not for the valley. For an exact quote on your bathroom, call us, estimates are free and the conversation is honest.
Talk to Tom Directly About Your Agoura Hills Bathroom
On a 1980s hillside tract home above Las Virgenes Valley, our crew opened a primary bath to find original galvanized supply lines, aluminum branch wiring, and a load-bearing wall with undersized headers from a previous homeowner patch. Because the home sits in the VHFHSZ, the permit triggered a Chapter 7A review of exterior wall penetrations. We coordinated the rough-in to keep vent pipes and exhaust terminations on the interior side or through ember-rated vents, wrote the re-framing allowance into the contract, and priced the copper repipe and AFCI circuit upgrade as a line-item change order approved in writing before we pulled wire. The homeowner never saw a surprise invoice.
That’s the job, done the way it should have been done the first time.
