Trusted Bathroom Remodeling for San Jose Homeowners
Our Bathroom Remodeling in San Jose typically runs between $10,620 and $33,040 for a full renovation, depending on the size of the room, the fixtures you choose, and whether you’re moving plumbing. That’s the real number we put in writing before any work starts, not a verbal ballpark that drifts upward after demolition day. Since 2004, the Kingswell standard has been simple: a written price, a defined arrival window, and a 365-day promise to make it right if something fails. Trevor Nash leads our San Jose team, and we’re the ones who answer when you call (669) 274-2362.
Bathroom Remodeling Contractor
A bathroom remodeling contractor handles the structural, plumbing, electrical, and finish work that turns an outdated bathroom into a room you actually enjoy using. You need one when the job involves more than swapping a faucet: moving a wall, relocating a toilet, rewiring for new lighting, or replacing a shower pan. Penhallow Remodeling San Jose is the general contractor that shows up with background-checked, uniformed technicians, a written price, and a written guarantee. Our full bathroom remodels in San Jose run $10,620 to $33,040. Small bathroom remodels start at $5,900. The number on day one is the number on your invoice.
What the Crew Actually Does
We pull the permits, protect the floors, and manage the subs – plumbing, electrical, tile, glass – so you’re not coordinating four different schedules from a group text. Every trade arrives with the walk-through already done and the materials staged. You’ll know who’s in your home because they’re in uniform and have passed a background check.
Materials That Match the Guarantee
We install cabinet lines like KraftMaid and Wellborn, countertops from Cambria and Silestone, and fixtures from Kohler, Moen, and Delta. Cambria quartz carries its own lifetime warranty alongside ours, so the product and the labor are both covered. That’s two layers of protection on one invoice.
Styles & brands we work with
Walk In Shower
A walk in shower replaces the curb and step-over threshold with a low-profile or barrier-free entry, which makes everyday use easier and the room feel bigger than it is. Homeowners in San Jose choose this when they want to age in place, eliminate scrubbing grout in a tub they never use, or modernize a master bath that still has a 1990s fiberglass surround. Penhallow Remodeling San Jose installs walk in showers for $5,310 to $14,160, depending on glass, tile, and whether we’re modifying the drain. Every quote is a written number, not a range that changes at the door.
Shower Pan and Waterproofing
The shower pan is the sloped base that directs water to the drain, and it’s the part that fails most often when shortcuts are taken. We use cement board substrate, the moisture-resistant layer behind your tile, and we flood-test the pan before a single tile is set. That’s the step that prevents the leak you won’t see until the ceiling below starts staining.
Glass and Hardware Choices
Frameless glass from recognized trade brands changes the whole look of the room, and it’s easier to keep clean than a curtain or sliding track. We’ll show you the difference between 3/8-inch and 1/2-inch glass, and give you a line-item price for each. You’ll pick the hardware finish, and we’ll install it with the same written guarantee as the rest of the job.
Bathroom Remodeling Companies
Bathroom remodeling companies range from solo operators working out of a pickup truck to full general contractors with payroll, insurance, and a physical office. The difference shows up when something goes wrong: a one-person crew can ghost you, but a company with a brand promise attached has a reason to come back. Penhallow Remodeling San Jose is part of the Kingswell family of companies, independently owned and operated, and every project carries the 365-Day Done Right Promise in writing. Our bathroom remodels run $10,620 to $33,040 in San Jose.
Questions to Ask Before You Hire
Ask for a written price, not an estimate range. Ask what happens if the work fails in the first year. Ask who answers the phone at 9 p.m. on a Tuesday. If they can’t answer those three, keep looking. We can answer all three, and we’ll put the first two in the contract.
The Kingswell Way Since 2004
The Kingswell standard is three sentences: say the price before the work, show up in the window we gave, and leave the place cleaner than we found it. Every Penhallow location operates to that standard, and each one is independently owned and operated. Trevor Nash leads our San Jose team with the same written guarantee that’s been the brand’s backbone for two decades.
Bathroom Renovation
A bathroom renovation means gutting the room down to the studs and rebuilding it so the layout, lighting, ventilation, and waterproofing all work together. It’s the right call when the room feels cramped, the vent fan doesn’t pull moisture, or the tile has been patched so many times it looks like a quilt. Penhallow Remodeling San Jose handles full bathroom renovations for $10,620 to $33,040. The written price covers permits, demolition, plumbing, electrical, tile, fixtures, and the final walk-through.
Layout Changes and Plumbing Moves
Moving a toilet or shower drain is the single biggest cost driver in a bathroom renovation, and it’s also the place where cheap bids fall apart. We’ll tell you upfront if moving the plumbing is worth it or if keeping the current rough-in saves you thousands without costing you the look you want. That conversation happens before we sign a contract, not after the floor is open.
Ventilation and Moisture Control
San Jose’s cool mornings create real condensation issues in bathrooms that don’t vent properly. We size the exhaust fan to the room, not to whatever was cheapest at the supply house, and we run the duct to the exterior properly. A bathroom that dries out is a bathroom that doesn’t grow mold behind the tile.
Small Bathroom Remodel
A small bathroom remodel refreshes a half bath, guest bath, or condo bathroom where space is tight and every inch has to earn its place. You need it when the vanity is dated, the toilet runs, and the room feels cramped even though the footprint hasn’t changed. Penhallow Remodeling San Jose remodels small bathrooms for $5,900 to $14,160, depending on fixture choices and whether we’re keeping the existing layout. It’s a smaller number than a full bath reno because the room is smaller, not because we cut corners.
Making a Small Room Work Harder
A wall-hung vanity, a corner sink, or a curbless shower can add usable floor space without moving a single wall. We’ll walk you through what’s possible in your specific footprint, and what each option costs in writing. Sometimes the right move is replacing a swinging door with a pocket door, and we’ll price that as a line item.
Condo and Townhome Considerations
San Jose condo projects come with HOA rules, shared wall constraints, and sometimes limited work hours. We’ve done small bathroom remodels in condo buildings where the water shutoff window is two hours and the freight elevator has to be reserved a week ahead. We handle those logistics, so you don’t get a call from the property manager at 4:50 p.m. on a Friday.
Shower Remodel
A shower remodel replaces the shower pan, tile, glass, and fixtures either a full gut or a targeted repair, depending on what’s failing. You need one when the grout won’t stay sealed, the pan creaks, or the shower head has the water pressure of a drinking fountain. Penhallow Remodeling San Jose handles shower remodels from $3,540 to $10,030. The written price includes demolition, waterproofing, tile, and new fixtures.
Waterproofing Done Right
The shower is the only place in your house where water sits against the walls on purpose, and the waterproofing is what keeps that water out of the framing. We install cement board and a waterproof membrane system, then flood-test the pan. If it holds water for 24 hours, we tile. If it doesn’t, we fix it before the tile ever goes up.
What a Shower Remodel Costs Less Than
A full shower remodel is cheaper than a full bathroom remodel because you’re not touching the floor, the vanity, or the toilet. In San Jose, that typically means $3,540 to $10,030 instead of $10,620 to $33,040. If the rest of the room is fine and the shower is the problem, this is the job that solves the problem without the full-bath price tag.
Tub to Shower Conversion
A tub to shower conversion removes the existing bathtub and replaces it with a shower base, walls, glass, and fixtures, usually without changing the footprint. Homeowners in San Jose make this switch when the tub is used twice a year but takes up forty square feet every day. Penhallow Remodeling San Jose handles tub to shower conversions for $4,130 to $11,800. The price depends on whether we’re reusing the existing drain location, the type of wall system, and the glass configuration.
Drain Location and What It Means
Most tubs have a 1 1/2-inch drain; most showers need a 2-inch drain to handle the flow rate. That often means opening the subfloor and replacing the drain line, which is exactly the kind of thing a verbal-ballpark contractor discovers mid-job and adds to your bill. We check the drain size during the walk-through and include any necessary repipe in the written price before we start.
The Aging-in-Place Angle
A tub to shower conversion is one of the most common aging-in-place upgrades in San Jose because it eliminates a 20-inch step-over at a time when that step becomes a fall risk. We can install a low-threshold base, a bench seat, and grab bars placed for where you actually stand. It’s the same written price and the same 365-Day Done Right Promise as every other job.
One Day Bath Remodel
A one day bath remodel focuses on replacing the tub or shower surround, pan, and fixtures without a full gut, which lets the crew finish the bulk of the work in a single day. It’s the right fit when the room’s layout works, the drywall is sound, and what you really need is a fresh, watertight shower. Penhallow Remodeling San Jose performs one day bath remodels as part of our broader Bathroom Remodeling in Santa Clara services, and the pricing depends on the wall system and fixture package. What stays the same is the written price and the written guarantee.
What a One Day Bath Is Not
A one day bath is not a full bathroom remodel. Moving plumbing, replacing subfloor, relocating a wall, or installing a custom tile shower takes longer, and anyone who tells you otherwise is pricing the job before they’ve seen the joists. We’ll tell you which kind of job you actually need, even when the cheaper answer is what we’d make less money on.
The Speed Without the Corners Cut
The reason a one day bath can be done in a day is that we’re installing engineered wall panels over sound framing with a system that’s built for it. The waterproofing still gets checked. The caulk lines still get tooled. The guarantee is still 365 days, in writing, on every project.

AfterBrands We Service
We service bathrooms built with Kohler, Moen, Delta, Toto, and Grohe fixtures, and we’ve worked on enough of each to know the common failure points without a service manual. Moen cartridges leak when they wear out; Delta valves stick when hard water builds up; Kohler tubs crack at the drain flange when the installer overtightened it. Knowing the brand helps us diagnose faster and quote more accurately.
We also work with cabinet lines KraftMaid and Wellborn, and countertop brands Cambria, Silestone, and Caesarstone. Cambria quartz is one we recommend often because it carries its own lifetime warranty alongside our 365-Day Done Right Promise. Whether you have a Kohler tub, a Moen valve, or a mix of brands from three different decades, we can help.
Signs You Need a Pro Right Now
- Grout that won’t stay sealed or keeps cracking. Cracked grout lets water reach the substrate, and by the time you see staining on the ceiling below, the framing is already wet. A pro can identify whether it’s a cosmetic re-grout or a waterproofing failure that needs a full tear-out.
- A shower pan that flexes or creaks when you stand on it. A pan that moves means the mortar bed underneath has failed or was never installed correctly. Ignoring it means water pooling under the pan and eventually rotting the subfloor.
- Mold you’ve cleaned that keeps coming back. Recurring mold means moisture is trapped somewhere it shouldn’t be – behind the tile, under the pan, or in the wall cavity. Cleaning the surface is a temporary fix for a problem that’s growing.
- Water stains on the ceiling below the bathroom. That stain is a leak, and leaks in bathrooms don’t stop until the source is found. The longer it runs, the more the repair costs, and the more likely the ceiling has to come down too.
- A toilet that rocks or a floor that feels spongy. A rocking toilet breaks the wax seal, and a spongy floor means the subfloor is already compromised. Both are repair-now situations, not wait-until-spring situations.
Our Process, Step by Step
- 1
The walk-through. We come out, look at the room, measure, check the drain size, and talk through what you’re trying to fix. You’ll get a written price after this visit – not before, because anyone pricing a bathroom sight unseen is guessing.
- 2
The written price. You get a line-item quote in writing covering materials, labor, permits, and any sub-trade work. The number on that page is the number on your invoice. No change orders unless you ask us to change the scope.
- 3
Permits and protection. We pull the permits, schedule inspections, and cover the floors and the path from the door to the bath. The job site gets cleaned at the end of every day, not just at the end of the job.
- 4
The work. Background-checked, uniformed technicians handle the demo, rough-in, waterproofing, tile, fixtures, and glass. We flood-test the shower pan, check the vent flow, and run the plumbing through its paces before we close the walls.
- 5
The walk-through and the guarantee. We walk the room with you, show you what was done, and hand you the written guarantee. It covers one full year from completion: if the work fails inside that window, we come back and fix it at no charge.
How Much Does Bathroom Remodeling Cost in San Jose?
A full Bathroom Remodeling in Cupertino typically runs $10,620 to $33,040, depending on the room’s footprint, the fixtures you choose, and whether you’re moving plumbing. A small bathroom remodel comes in at $5,900 to $14,160. A walk in shower installation runs $5,310 to $14,160, a tub to shower conversion runs $4,130 to $11,800, and a shower remodel runs $3,540 to $10,030. These are the written-price ranges we quote, not starting prices that climb after demo day.
The biggest cost drivers are plumbing moves, waterproofing scope, tile selection, and whether the room needs a new exhaust fan or electrical work. Custom tile work costs more than a one day bath wall system. A 2-inch drain upgrade costs more than reusing an existing shower drain. We’ll show you the line items and explain what each one buys, so you can decide where to spend and where to save. Every free estimate includes the full scope in writing: materials, labor, permits, and the 365-Day Done Right Promise.

Bathroom remodeling is tearing out and replacing the surfaces, fixtures, and systems in a bathroom – tub, shower, tile, vanity, toilet, lighting, and ventilation – to update the room and fix any underlying damage.
