Fast, Reliable Bathroom Remodeling Across Los Gatos
A full bathroom remodel in Los Gatos typically runs $9,000 to $28,000, and most projects take two to five weeks, but the price and schedule here are shaped by real local factors: hillside foundations, older framing from the Craftsman era, and the Los Gatos hillside development rules that can turn a simple footprint change into a structural review. Our crews know those streets and those houses, and we give every Los Gatos homeowner a written price before demo starts. Call (669) 274-2362 and we’ll walk the space with you, measure, and hand you a line-item number you can hold us to.

Why Penhallow Remodeling San Jose Is Los Gatos’s Preferred Bathroom Remodeling Company

Los Gatos homeowners tell us the same story, and it usually starts with a handshake estimate that didn’t survive the first week of framing. Our answer is different on purpose. We run Bathroom Remodeling jobs under The Kingswell Way: a written price before the first tile is pulled, a defined arrival window, and a 365-Day Done Right Promise that says if something fails inside that year, we come back and make it right at no charge. That promise is in writing on every project we start in Los Gatos.
Trevor Nash, who leads our team, is the person who walks you through the number before you sign anything. He explains what a cement board substrate is, why a hillside bath needs upgraded shear on the wet wall, and what the inspection sequence looks like. You get background-checked, uniformed technicians on the job, and a live person answers the phone day or night. Dispatch and scheduling for Los Gatos are coordinated from our San Francisco Bay Area office, with crews working locally in Los Gatos every week.
On a 1920s Craftsman near Los Gatos Creek, our crew uncovered a failing subfloor under a second-story bath where a previous owner had altered the rough-in without permits. We coordinated the inspection sign-off, replaced the joists, and installed a cast-iron Kohler tub with a custom millwork vanity matched to the home’s original trim. That job finished on the written price, and the homeowners knew what was happening at every inspection point. That’s the standard we bring to every street in Los Gatos, from Almond Grove to the west side hills.

Tub to Shower Conversion in Los Gatos
A tub to shower conversion in Los Gatos is a $3,500 to $10,000 project for a standard 60-inch footprint, and it is one of the most useful changes you can make in an older home where the only tub is also the only bathing surface. The job involves removing the existing tub, assessing the drain location and the wall framing behind it, then building a shower pan or prefabricated base, waterproofing the walls with cement board substrate (the moisture-resistant layer behind your tile), and installing the valve, glass, and finishes.
What pushes the Los Gatos price toward the upper end is usually not the shower itself. It is the condition of the joists under the tub, the age of the cast-iron drain, or the fact that the bathroom sits on a non-conforming addition along Los Gatos Creek that triggers a current-code upgrade the moment we open the wall. If you are converting a tub in a hillside home with a raised foundation, blocking and shear on the wet wall can add real labor and material. We don’t hide that; we put it in the written estimate as a line item.
The Right Fixtures for the Space
We stock and install Kohler and Moen fixtures for most Los Gatos conversions, plus Delta, Toto, and Grohe where the spec calls for it. If you want a linear drain or a zero-threshold entry, we plan the slope and the waterproofing around it before we order anything.
Permits and Rough-In
When the conversion requires a valve move or a drain relocation, we pull the permit and schedule the rough-in inspection. On an old home, an inspector can flag venting or joist notching from decades ago, which is why we open the wall to see what’s actually there before we quote the final scope.
One Day Bath Remodel in Los Gatos
A One Day Bath Remodel in Los Gatos means the visible surfaces are done in a single workday, and it typically runs $5,000 to $12,000 depending on what is being replaced. This is a good option when the bathroom footprint stays the same, the existing tub or shower base is sound, the valve location does not move, and you are replacing the surround, the fixtures, the glass, and the trim rather than re-framing or re-plumbing the room.
In a 1920s Craftsman in Los Gatos, that one-day promise often meets reality the minute we remove the old surround. The original walls were sometimes lathe and plaster over framing that has settled out of square, and the subfloor may have rot where the old tub flange leaked for decades. When that happens, we stop, show you what we found, and give you a written change order before any extra work happens. A real one-day remodel only stays one day when the bones underneath are already sound; when they are not, we tell you on the spot.
What We Can Replace in One Day
We can replace the tub or shower surround, install a new tub or shower base, swap the valve trim and fixtures, set the glass enclosure, and finish the caulk joints in a single day when the substrate is clean. Custom tile work and slab panels are not one-day items; those are designed and templated ahead of time so the install day stays tight.

Setting Expectations
We will never promise a one-day bath on a house with a failing subfloor or a fixture spread that does not line up. The honest answer, before we agree to the schedule, is found in a free on-site look at the actual conditions. Call (669) 274-2362 and we’ll tell you straight whether your Los Gatos bathroom is a one-day job or a three-week one.
Trusted Brands We Service in Los Gatos
We install Cambria quartz, Silestone, and Caesarstone slabs on vanities and shower curbs, and Wellborn cabinetry for custom vanities built to the exact dimensions of your bathroom. Having local relationships with suppliers who serve the Bay Area means when a slab arrives wrong or a cabinet door shows up with a finish flaw, we can usually get a replacement moving within days rather than waiting on a cross-country line. For Los Gatos customers, that can be the difference between a six-week remodel and a nine-week one. We also carry the common drain assemblies, valve cartridges, and curb caps we see in Los Gatos homes, so the small corrections do not stall the schedule.

AfterCommon Bathroom Remodeling Problems We See in Los Gatos Homes
- Hillside foundation movement. The expansive clay soils on Los Gatos hillsides shrink in summer and swell in winter, and that movement shows up as cracked shower pans, popped tile in wet areas, and doors that no longer close square. We inspect the floor framing before setting any pan or tile.
- Non-conforming additions and old rough-ins. Many flatland homes near the Los Gatos Creek corridor have bathrooms added without permits decades ago. Drain lines are undersized, venting is wrong, and the moment we open a wall, the inspector may require upgrades to current code. None of that is optional.
- Failing subfloors under second-story baths. In the Victorian and Craftsman stock from the late 1800s and early 1900s, a slow tub or toilet leak rots the joists below the bath. You can’t set new tile over a moving floor; we repair the structure first and show you photos.
- Heritage tree and hillside review triggers. On west side Los Gatos properties, even an interior bathroom remodel can touch the review process if the home sits on a hillside lot with protected trees near the work zone. We handle the coordination, but it affects the timeline and the paperwork.

FAQs About Bathroom Remodeling in Los Gatos
They can add review time and cost even when the bathroom footprint never changes. Homes on hillside lots, particularly on the west side of Los Gatos, often carry hillside development standards and heritage tree protections that trigger a planning or arborist review when work opens walls or changes drainage. In the Los Gatos Creek corridor, older homes with non-conforming additions face a special situation: a remodel can force you to bring the entire addition up to modern hillside development standards, not just the bathroom you are touching. We check the property’s planning history before we quote. Call (669) 274-2362 and we’ll explain what applies to your address.
Because the structure under the tub is often older than the tub itself. Los Gatos has a high share of homes built before 1950, and in those houses the original joists may have been notched for plumbing, the subfloor may have water damage, or the wet wall may have been altered in a previous remodel without permits. When we open the wall, the inspector can require venting, shear, or structural upgrades that fall outside the bare conversion scope. We carry the real price difference as a written line item, not a surprise at the punch list.
Only if the underlying structure is sound and the fixture spread matches what is already there. A 1920s Craftsman bathroom with original lathe and plaster, out-of-square framing, and an old cast-iron tub flange rarely qualifies once we open the wall. We will do a one-day install only when the subfloor, valve location, and substrate allow it; otherwise we tell you honestly what the real timeline is and put that in writing. Call (669) 274-2362 for a straight assessment.
We template and order long-lead items before we open the wall, and we never order custom architectural glass before the rough-in inspection passes. The pattern we see too often: a contractor specifies an allowance without line-item detail, and the homeowner expects a Cambria slab while the allowance actually covered prefab quartz. We solve that by naming exact slabs, exact cabinet lines, and exact glass specs in the written quote, with product numbers. Then we order in a sequence that keeps the job moving even if one vendor lags.
Get it on paper before you touch it. An unpermitted bathroom addition, especially one along the Los Gatos Creek corridor or on the hillside, can become a legal and structural problem the moment you remodel the room. The county, and often the current hillside development standards, may require you to bring the entire addition into compliance, including setbacks, drainage, and structural review. We can inspect the space, review the planning history with you, and give you a written recommendation before deciding whether to file a permit for remediation or move forward with the remodel. That conversation is free.
