Why Penhallow Remodeling Is Los Altos’s Preferred Bathroom Remodeling Company
Los Altos homeowners have been burned before. A contractor who never showed, a verbal estimate that doubled after demo day, a shower pan that leaked six weeks after the final check cleared. Trevor Nash founded Penhallow Remodeling to work differently, and the difference starts with a written price before any work starts and a written guarantee on every project.
We know that a bathroom inside a 1948 to 1975 ranch is rarely just tile and fixtures. Those homes have original single-pane windows, undersized electrical panels, and slab foundations that fight a drain move. Our estimators look behind the cosmetic layers during the first visit because that’s where the real work, and the real cost, usually hides. Our Bathroom Remodeling team has handled enough Los Altos ranches to open a wall and not be surprised by what’s inside.
Scheduling and dispatch are coordinated from the San Francisco Bay Area office, and our background-checked, uniformed technicians arrive on a defined window. A live person answers the phone 24/7, not a voicemail tree. That matters when your shower valve is mid-install and you need an answer before the inspector walks through at 3 p.m.
Bathroom Remodeling Contractor in Los Altos
A Bathroom Remodeling Contractor in Los Altos handles the full scope: demolition, rough-in, waterproofing, tile, cabinets, countertops, glass, fixtures, and final inspection. In Los Altos, a full bathroom remodel typically runs $9,000 to $28,000 depending on the size of the room, the condition of the wall cavity, and whether the project includes long-lead custom millwork and Cambria or Silestone slabs.
Custom Cabinetry and Millwork
High-end bathrooms in Los Altos lean into custom vanities, built-in linen storage, and architectural millwork that reads like furniture, not a big-box cabinet. We order Wellborn cabinetry to spec, which means the vanity arrives dimensionally correct for your wall even when the wall is 3/4 inch out of square. That lead time runs six to nine weeks, so we sequence the rough-in and tile around it.
Slab-On-Grade Rough-In
Most Los Altos ranches sit on slab foundations, which means moving a shower drain isn’t a matter of sawing through framing. It’s concrete cutting, re-piping, and a re-inspection. We budget for that reality before the tile order is placed, and we tell you exactly what the drain relocation will cost so you can decide before the hammer comes out.
Walk In Shower in Los Altos
A Walk In Shower in Los Altos is the upgrade we see most often when homeowners are done with cleaning grout lines on an old tub surround. A curbless or low-curb walk in shower install runs $4,500 to $12,000 depending on the glass enclosure, the waterproofing method, and whether the drain stays put or has to move through a slab.
Frameless Glass and Waterproofing
We build the shower to hold water for decades, not just pass a quick spray test. That means cement board substrate (the moisture-resistant layer behind your tile), a bonded waterproofing membrane at every seam and corner, and a sloped pan that drains correctly under a frameless glass enclosure. The glass itself is measured after tile, never before.
Tub-to-Shower Work in Ranches
Most 1960s Los Altos tubs sit on a cast iron waste line that has to be handled on a slab. A tub-to-shower conversion runs $3,500 to $10,000 here, and the spread is almost entirely the drain work plus whatever the inspector requires for the new shower valve’s thermostatic protection. We quote the plumbing reality, not the brochure number.
Trusted Brands We Service in Los Altos
We install product lines that carry their own warranties alongside ours: KraftMaid and Wellborn cabinetry, Cambria, Silestone and Caesarstone countertops, Kohler and Moen fixtures, and Delta and Toto trim. We service and install these brands across Los Altos, and because our materials come from established local supply lines, a replacement valve cartridge or a damaged shelf bracket doesn’t sit in a warehouse queue for two weeks. The layer of protection here is real: Cambria quartz carries a lifetime warranty, and our 365-Day Done Right Promise sits behind the installation, in writing.
Common Bathroom Remodeling Problems We See in Los Altos Homes
- Undersized electrical panels. The original 100-amp panel in a 1960s ranch is often already fully subscribed, and adding a heated floor, a towel warmer, or even a second GFCI circuit means a panel upgrade or a subpanel solution. We identify this during the estimate, not after the electrician opens the wall.
- Slab drains that won’t move without cutting concrete. Ranches built from 1948 to 1975 put the bathroom drain where the original tub sat, and that footprint rarely matches a modern walk in shower layout. Cutting a slab triggers a re-inspection and adds days to the schedule, so we plan for it or design around it before the first cut.
- Long-lead materials ordered before the scope is fixed. We’ve seen millwork and Cambria slabs purchased early to lock a rebate, only to sit in a Los Altos garage for six weeks while a wall opens and a change order lands. We fix scope, allowances, and the draw schedule in writing before ordering a single long-lead item.
- Heritage Tree root-zone conflicts. If a protected oak or bay laurel sits close to a planned addition that touches the bathroom footprint, Los Altos requires a certified arborist review and root-zone fencing before work can proceed. A missed tree adds weeks and thousands in mitigation, so we check the city’s tree map on every project.
Pricing for Bathroom Remodeling in Los Altos, CA
Bathroom remodeling in Los Altos isn’t the cheapest in the Bay Area, and the reasons are structural. Your house sits on a slab. Your electrical panel is likely original. And if your project touches the building envelope, the city’s Heritage Tree ordinance can require an arborist review that neighboring cities don’t ask for. Here’s what to budget:
| Bathroom Remodeling Service | Los Altos 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 |
The biggest cost drivers are the drain location, the waterproofing method, and whether you’re choosing stock or custom cabinetry. We hand you a written price before work starts, and that number is the number on the invoice. Call (936) 259-2607 to schedule a free estimate and get your written number.

FAQs About Bathroom Remodeling in Los Altos
A Los Altos remodel costs more because the housing stock is older on average and the regulatory layer is stricter. Most Los Altos bathrooms sit in 1948 to 1975 ranches on slab foundations with original single-pane windows and undersized panels, so a third to half the budget can go behind the wall on plumbing, electrical, and waterproofing before visible finishes start. Mountain View’s newer townhome and condo inventory doesn’t carry the same rough-in reality.
Add to that the Heritage Tree ordinance, which can require a certified arborist review and root-zone fencing if a protected oak or bay laurel sits near the work area. That’s a cost and a delay a Mountain View bathroom at the same square footage may never encounter. Call (936) 259-2607 and we’ll walk your specific house before we quote it.
Custom millwork and cabinetry are the schedule setters, not labor. Wellborn and KraftMaid vanities run six to nine weeks from order to delivery, and Cambria and Silestone slabs run four to eight weeks. Frameless glass is usually two to three weeks after tile. We sequence the rough-in, waterproofing, and tile to line up with those lead times so the project doesn’t stall waiting on material.
That’s also why we never order long-lead material until the scope of work, allowances, and draw schedule are fixed in writing. Ordering early to chase a rebate is the most common way a Los Altos bathroom project stalls or bloats. Call (936) 259-2607 and we’ll walk you through the sequencing before you sign anything.
Yes, any remodel that moves plumbing, changes the electrical, or alters the building envelope requires a permit in Los Altos. We pull the permits, call the inspections, and pass the final before we hand you the punch list. We don’t do unpermitted work, and we budget the permit and inspection time into the written price from day one.
If your project touches protected trees, the city requires the arborist review before the building permit is approved, not after. That’s a Los Altos-specific step we handle early so your schedule doesn’t stall mid-demolition. Call (936) 259-2607 with your address and we’ll tell you what your project will likely trigger.
Often, yes. We can keep the existing drain location and convert a standard 5-foot tub to a walk in shower with a linear drain placed where the tub drain already sits, avoiding slab cutting entirely. That keeps the project in the $3,500 to $10,000 range and skips a concrete re-inspection.
On a ranch off Covington Road we pulled an original 1960s tile bath and found a 100-amp panel fully subscribed and a slab with no room to move the drain without cutting concrete. We re-routed the rough-in within the existing footprint, added a dedicated GFCI circuit, and set a Kohler shower valve with a Cambria-topped Wellborn vanity. The Heritage Tree root-zone fencing was signed off before we closed the walls. That’s the way we work every Los Altos job. Call (936) 259-2607 to see if your drain can stay put.
If your bathroom remodel is part of an addition or touches an exterior wall near a protected oak or bay laurel, the city’s arborist can require root-zone fencing, construction method changes, or even a foundation redesign. That’s a Los Altos-specific requirement that doesn’t exist in Mountain View or Sunnyvale, and a missed tree can add weeks and $15,000 to $30,000 in mitigation.
We check the city’s protected tree map during our first visit, before a single line item is fixed. That way, the Heritage Tree review is in the written price and the schedule from day one, not a surprise that lands after demo. Call (936) 259-2607 and ask us to check your property before you spend a dollar on design.
