Bathroom Renovation in Palo Alto & the Bay Area
A beautifully renovated bathroom adds daily comfort, real property value, and long-term quality of life to your home. At Sami & Sons, we design and build custom bathroom renovations for homeowners across Palo Alto, San Jose, Mountain View, Sunnyvale, and the greater Bay Area. Whether you're updating a dated hall bath, building out a spa-quality primary suite, or converting an unused tub into a walk-in shower, our licensed team handles the entire project — design, permits, demolition, plumbing, electrical, tile, cabinetry, and final finishing — under one roof.
We are a family-owned, licensed general contractor with 15+ years of experience and over 1,000 completed Bay Area renovation projects. Our bathroom work ranges from focused upgrades like a new shower surround and vanity to complete gut-and-rebuild renovations with radiant heated floors, custom tile showers, freestanding soaking tubs, and double vanities. Whatever your scope, we approach every bathroom with the same level of care, transparency, and craftsmanship that has earned us a 96% customer return rate across the Bay Area.
Our Bathroom Renovation Process
We start with a detailed in-home consultation — measuring your space, reviewing what works and what doesn't in your current bathroom, and understanding exactly how you want to use it. From there, we develop a full 3D design rendering that shows your new bathroom in detail: tile selections, vanity placement, shower configuration, lighting, and fixtures. You see exactly what you're getting before we touch a single wall, so there are no surprises and no disappointments.
Once you've approved the design, we handle all permits with your local building department. Our licensed in-house team then manages every trade — plumbers, electricians, tile setters, and finish carpenters — maintaining a clean, organized work environment daily and communicating regular updates throughout the project. We complete a thorough walkthrough with you before we consider any bathroom renovation finished.
Bathroom Renovations Built for Bay Area Homes
Homes in Palo Alto and the greater Bay Area often present specific renovation challenges: aging galvanized or cast iron drain lines that need upgrading, subfloor moisture damage from decades of inadequate waterproofing, and shower pans that were never properly sloped or sealed. We know what to look for — and how to address these issues correctly — so your new bathroom performs as well as it looks, for decades.
All plumbing work we perform meets California Plumbing Code. All electrical work meets California Electrical Code. Every permit is pulled, every inspection is passed, and every project is fully documented — which protects your investment and gives you full transparency at resale.

Custom Walk-In Showers & Tub Installation
The shower is the centerpiece of most bathroom renovations — and it's where we see the most dramatic transformations. We design and install custom walk-in showers with frameless glass enclosures, large-format porcelain or natural stone tile surrounds, built-in niches, linear or center drains, bench seating, and multi-function shower systems with body sprays and hand showers. The result is a shower that feels spacious, clean, and genuinely luxurious — not just an upgraded version of what was there before.
For soaking tubs, we install freestanding tubs, alcove tubs, and drop-in configurations — handling all structural reinforcement, plumbing rough-in, and surrounding tile or stone work. Tub-to-shower conversions are among our most popular bathroom requests in the Bay Area: we remove the existing tub, assess and reinforce the subfloor, install a properly waterproofed custom shower in its place, and transform a bathroom that felt cramped into one that feels open and modern.
Every shower we build uses a certified waterproofing membrane — Schluter Kerdi, WEDI, or equivalent — installed by our licensed plumbers. This isn't optional and it isn't something we cut corners on. Proper waterproofing is what separates a shower that looks great for 20 years from one that causes water damage behind the walls within five.
Custom Vanities, Tile Work & Premium Fixtures
The vanity sets the style tone for your entire bathroom — and the right tile selection ties everything together. We design and install custom and semi-custom vanity systems in a full range of door styles, finishes, and configurations: single vanities, floating double vanities, tower storage units, and built-in linen cabinets. Every layout is planned for how you actually use the space — with careful attention to storage, counter space, mirror placement, and lighting.
Our tile work covers shower surrounds, feature walls, floor installations, and decorative accents. We work with large-format porcelain, ceramic, natural marble, travertine, quartzite, and glass mosaic — sourced from trusted Bay Area suppliers we've worked with for years. We install every tile with the precision and attention to pattern alignment, grout joint consistency, and transition detailing that separates truly high-quality tile work from the average.
For plumbing fixtures, we work with Kohler, Moen, Delta, and Grohe — selecting products that balance aesthetics, reliability, and long-term warranty coverage. We're happy to work with fixtures you've already selected or help you build a complete material package from scratch. Either way, every fixture we install is tested before we consider the job complete.
Heated Floors, Plumbing Upgrades & Accessibility Features
The details that elevate a bathroom renovation from good to exceptional are often the ones you feel rather than see. Radiant heated floors — installed as an electric mat system under your tile — provide warmth underfoot from the moment you step out of the shower. We install Schluter DITRA-HEAT and similar systems during the tile-setting phase, controlled by a programmable thermostat that lets you set schedules so the floor is warm when you need it without running constantly.
For plumbing upgrades, we replace aging supply and drain lines, install pressure-balance or thermostatic shower valves, upgrade to water-efficient toilets and faucets that meet California's strict plumbing standards, and reconfigure plumbing layouts where the renovation calls for it. All plumbing work is performed by our licensed plumbers and inspected to California code.
We also incorporate accessibility features where clients want them — ADA-compliant grab bars, barrier-free shower entries, comfort-height toilets, non-slip flooring, wider doorways, and turning-radius planning that makes bathrooms safe and comfortable for all ages. These features can be designed to look completely intentional rather than institutional, and they add real value for buyers at resale.

Bathroom renovation costs in the Bay Area typically range from $18,000–$35,000 for a secondary bathroom update and $40,000–$80,000+ for a full primary bathroom renovation.
