Trusted Bathroom Remodeling for Orange County Homeowners
A bathroom remodel in Orange County typically runs $9,000 – $28,000, and the honest answer is that most of that cost lives behind the walls: waterproofing, ventilation, and the plumbing rough-in. The visible finish work matters, but a remodel that fails in eighteen months usually fails because someone skipped the substrate prep. Penhallow Remodeling puts the price in writing before a single tile is pulled, and the 365-Day Done Right Promise covers what we build for a full year after the crew leaves. Trevor Nash leads our Orange County team, and you’ll get the same answer from the first phone call to the final walkthrough: a real number, a real schedule, and a guarantee you can hold us to. Call (424) 541-1701 to talk through your project.

- A full bathroom remodel in Orange County runs $9,000 – $28,000 depending on size, materials, and how much plumbing moves.

- We install recognized trade brands: Cambria, Kohler, Moen, Delta, and KraftMaid cabinetry.

Bathroom Remodeling Contractor

A Bathroom Remodeling Contractor is the licensed professional who manages the whole job: demolition, plumbing, electrical, waterproofing, tile, cabinetry, and finish work. You need one when the project touches anything structural or behind the wall, not just cosmetic swaps. Penhallow Remodeling handles the full scope in Orange County, and a typical remodel runs $9,000 – $28,000 depending on size, layout changes, and material grades. We give you a written price before the first cabinet comes out, so the number on day one is the number on the invoice.
What a contractor actually does
We pull permits where Orange County code requires them, schedule inspections, and coordinate the trades in the right order so the work passes the first time. That sequencing is where remodels go wrong; tile set before waterproofing cures is a tear-out waiting to happen. Our crews follow the Kingswell standard on every job site: show up in the window we quoted, keep the site clean, and don’t leave until you’ve walked the work with us.
Why we write the price down
Verbal estimates have a way of growing after demo day. We hand you a written, line-item number before work begins, and that number holds unless you change the scope. The 365-Day Done Right Promise backs the workmanship for a full year in writing, so if something fails inside that window, we come back and fix it at no charge.
Styles & brands we work with







Walk In Shower
A Walk In Shower replaces the tub or old shower with a curbless or low-threshold shower pan that’s safe to step into without lifting your feet over a tub wall. It’s the right call for aging-in-place, mobility concerns, or just a cleaner, more open bathroom feel. A walk-in shower installation in Orange County typically runs $4,500 – $12,000 depending on glass enclosure options, tile choices, and whether we’re moving the drain. Penhallow Remodeling handles the full conversion, including the waterproofing layer most homeowners never see but absolutely depends on.
Waterproofing comes first
Behind every shower we build, there’s a bonded waterproof membrane or cement board substrate (the moisture-resistant layer behind your tile) installed before a single tile touches the wall. Orange County’s coastal humidity makes this step non-negotiable. Skip it and you’ll find mold inside the wall cavity within a couple of years. We show you the waterproofing before it gets covered, so you know what’s under the tile.
Layout and glass options
From a simple 36-inch corner unit to a full wet room with a linear drain and frameless glass, the layout drives the price. We’ll walk you through the tradeoffs: frameless glass panels run more than framed doors but are easier to keep clean. The goal is a shower you’ll use every day without thinking about it.
Bathroom Remodeling Companies

Bathroom Remodeling Companies range from solo operators with a pickup truck to full-service general contractors with dedicated project managers. The difference shows up in the details: who answers the phone, who shows up, and who stands behind the work when something fails. Penhallow Remodeling Orange County operates under the Kingswell Guarantee, established in 2004, which requires a written price before any work starts, a defined arrival window, and a written guarantee on every project. A full remodel runs $9,000 – $28,000.
Questions to ask any company
Ask if the price is written or verbal, ask who pulls the permit, and ask what the warranty covers in writing. Those three questions eliminate most bad actors quickly. We answer them up front, in writing, without being asked. The 365-Day Done Right Promise means if the work fails inside the guarantee period, we return and fix it at no charge.
Why homeowners call us second
A large share of our Orange County clients come to us after a previous contractor burned them: a shower pan that leaked six weeks after the final check, a tile job with lippage you can see from across the room, an invoice that ballooned after demo day. We’re the call you make when you’re tired of guessing. The promise is simple: written price, real schedule, and we make it right if it’s not.
Bathroom Renovation
A Bathroom Renovation means updating an existing bathroom’s function and finish: new fixtures, new tile, maybe moving a wall or relocating the toilet. It’s different from a repair in that everything comes out and goes back in fresh. In Orange County, a full renovation runs $9,000 – $28,000, and the most common scope we see in places like Irvine, Tustin, and Fullerton is a master bath with a double vanity, walk-in shower, and new flooring. Penhallow Remodeling pulls the permits, manages the inspections, and hands you a written price before demolition starts.
What drives renovation cost
Moving plumbing is the single biggest cost driver; keeping the toilet and shower where they are saves thousands. Material grade is second: a Kohler or Moen fixture set costs more than big-box basics but carries better warranties. Countertop choice matters too. Cambria and Silestone quartz run more than laminate, and they hold up to Orange County’s hard water better.
The order of operations
Demolition, rough plumbing and electrical, inspection, insulation and drywall, waterproofing, tile, fixtures, finish. We don’t skip the inspection step; a failed inspection costs you time and rework. Every Penhallow job gets permits pulled and inspections passed before we call it done.
Small Bathroom Remodel

A Small Bathroom Remodel focuses on a half bath, guest bath, or compact primary bath, usually under 50 square feet. It’s the most cost-effective way to add value and function, and in Orange County it typically runs $5,000 – $12,000 depending on whether you’re keeping the footprint and swapping finishes or moving anything. Penhallow Remodeling handles these all the time in older Orange County homes, including Bathroom Remodeling - Laguna Woods, where the hall bath hasn’t been touched since the Nixon administration. The written price still applies, same guarantee, same standard.
Getting the most from a small space
Floating vanities and wall-hung toilets create visual floor space without moving walls. A corner shower with a curved glass panel can fit where a tub never would. We’ll show you layout options on paper before you commit, so you can see what fits and what doesn’t. In a small bath, an inch matters; we measure twice and order once.
Speed and budget control
A small bath can often be done in 2 – 3 weeks because there’s less square footage and fewer material decisions. That’s not a promise of a one-day turnaround; it’s a realistic window we’ll put in writing. The budget stays controlled because we price the job before demo, not as a holding pattern while we figure it out.
Shower Remodel
A Shower Remodel means tearing out the existing shower and rebuilding it, not just replacing a showerhead or recaulking. You need it when the pan leaks, the tile is cracked and letting water through, or the space simply doesn’t work anymore. In Orange County, a shower replacement runs $3,000 – $8,500 depending on tile, glass, and whether the drain moves. Penhallow Remodeling specializes in diagnosing why the old shower failed, so the new one doesn’t repeat the same mistakes.
Diagnosing the failure first
Most shower failures in Orange County come from one of three things: a failed pan membrane, missing or improperly installed waterproofing at the walls, or poor ventilation leading to mold behind the tile. We open the worst section first and document what we find, so you’re not paying us to guess. If the damage is worse than expected, we stop and re-price the change before continuing, not after.
Materials that hold up
We set tile on cement board or bonded waterproof membrane, never on greenboard drywall. Our standard fixtures come from Kohler, Moen, Delta, and Toto; you can upgrade to Grohe if you want European hardware. The point is that the materials behind the guarantee are as solid as the guarantee itself.
Tub to Shower Conversion
A Tub to Shower Conversion removes the bathtub and builds a walk-in shower in the same footprint. It’s popular in Orange County for a few reasons: homeowners rarely use the tub, the shower is easier to enter, and the floor plan opens up. A tub-to-shower conversion runs $3,500 – $10,000 depending on the shower base, glass enclosure, and tile selection. Penhallow Remodeling handles the whole job including drain relocation and any plumbing changes required by code.
What changes under the floor
A tub drain sits at the end of the fixture; a shower drain typically moves to the center. That means cutting into the subfloor and reworking the trap, which is where the cost and the risk live. We pull the permit, and the plumbing inspector checks the work before it gets covered. That’s not optional on our jobs; it’s how the Kingswell standard works.
The curb or curbless decision
A curbless shower needs more floor structure to slope the drain properly without a raised threshold. It’s an accessibility choice that many Orange County homeowners make for aging in place. We’ll show you both options with real numbers, so you can decide whether the extra cost is worth it for your situation.
One Day Bath Remodel
A One Day Bath Remodel is a specific product: an acrylic or composite shower system installed over your existing walls in a single day, no tile, no custom glass. It’s a faster, lower-cost option than a full custom remodel, and it’s honest when the current shower’s bones are solid but the surface looks rough. Penhallow Remodeling can coordinate these installations for Orange County clients who want a clean result without a multi-week project. The written price still applies.
What a one-day install can and can’t do
A one-day system covers the walls and pan but doesn’t fix water damage hiding behind them, and it doesn’t move drains or replace rotting framing. If we find damage during the tear-out, we stop and give you a new written price before proceeding. That’s the difference between a one-day product and a one-day lie; we won’t sell you the second one.
Is it worth the tradeoff?
A one-day bath typically runs toward the lower end of the range, and it’s a solid choice for guest baths and rentals. For a primary bath where you want custom tile, a curbless entry, or better ventilation, a full remodel is the better long-term investment. We’ll quote both and let you decide with all the numbers on the table.

AfterBrands We Service
We install and stand behind materials from Kohler, Moen, Cambria, KraftMaid, and Delta, because those brands carry warranties that back up our own 365-Day Done Right Promise. Cambria quartz includes a full lifetime warranty from the manufacturer; that’s layers of protection, not just a handshake. We also work with Wellborn cabinetry and Caesarstone when the design calls for it.
Whether your project uses Kohler fixtures, a Cambria vanity top, or any other recognized trade brand, we can help. The brand matters, but the installation matters more; a great fixture installed badly still leaks. We do both right.
Signs You Need a Pro Right Now
- Water stains or soft spots on the ceiling below a bathroom. That means water is getting through the floor or the pan, and by the time you see the stain, the subfloor may already be compromised. This is a call-today situation, not a wait-and-see.
- Musty odor that comes back after cleaning. Recurring mildew smell usually means mold is growing where you can’t see it, behind tile or inside the wall cavity. Surface cleaning won’t fix what’s hidden.
- Loose or cracked tiles around the shower or tub. Cracked grout lets water behind the tile, and once the substrate gets wet, the tile loses its bond. It’ll only spread from there.
- A shower pan that flexes when you stand in it. A solid pan shouldn’t move. Flex means the support underneath has rotted or the pan wasn’t set right, and standing on it is making it worse.
- Visible mold on grout lines that returns within a week of scrubbing. That’s not surface mold; that’s moisture feeding it from behind. Ventilation and waterproofing need a professional look before the problem spreads.

How Much Does Bathroom Remodeling Cost in Orange County?
A primary bathroom remodel in Orange County typically runs $9,000 – $28,000, and the spread comes down to three things: how much plumbing moves, how much tile you choose, and what grade of fixtures and countertops you pick. A guest bath refresh might land around $7,000, while a master bath with a double vanity, walk-in shower, and heated floors in our Bathroom Remodeling in Orange or Newport Beach can push the upper end. A walk-in shower installation alone runs $4,500 – $12,000; a tub-to-shower conversion runs $3,500 – $10,000.
What drives the number up? Moving a drain or toilet, adding a window, upgrading to frameless glass, choosing Cambria or Silestone quartz over a standard countertop. What drives it down? Keeping the existing footprint, choosing porcelain over natural stone, and installing a standard Kohler or Moen fixture set instead of custom hardware. The best way to avoid overpaying is to get a written line-item quote, not a ballpark, and to ask what’s not included. Our free estimates include the full scope: labor, materials, permits, and a written guarantee. Call (424) 541-1701 to schedule yours.
