Bathroom Remodeling in Redwood City & Silicon Valley

Turn your everyday bathroom into a private spa retreat with custom design, luxury finishes, and meticulous craftsmanship.

Your bathroom should feel like a place to exhale, not just another room you rush through. Calwest Builders specializes in high-end bathroom remodeling that turns outdated or cramped spaces into spa-like retreats tailored to how you live. From contemporary master baths in Menlo Park to elegant powder rooms in Atherton and Redwood City, we blend function, comfort, and visual impact in every design. Think large walk-in showers with rainfall heads, freestanding soaking tubs, premium tile, layered lighting, and thoughtful details that make your daily routine feel indulgent.


Comprehensive Bathroom Remodeling Services

Custom Showers & Tubs

We design and build oversized walk-in showers that feel like your own private spa, complete with frameless glass enclosures, multiple shower heads, and optional steam systems. Bench seating, recessed niches, linear drains, and carefully planned lighting add both comfort and convenience. Whether you prefer a sleek curbless shower or a more traditional layout, every detail is engineered for performance and luxury. For an extra level of relaxation, we can integrate freestanding soaking tubs or jetted tubs positioned as focal points in your bathroom.

Vanities & Storage

A well-designed vanity becomes both a statement piece and a hardworking storage hub. We create custom double-sink vanities for primary suites, floating vanities for modern minimalism, and furniture-style vanities for timeless elegance. Integrated storage solutions—linen towers, built-in shelving, recessed cabinets, and organized drawers—keep everyday essentials within reach while preserving clean, uncluttered lines. The result is a space that looks curated and lives effortlessly.

Tilework & Flooring

Tilework is where craftsmanship truly shows. Our team meticulously installs luxury materials such as large-format porcelain, marble, and stone, with precise layout and clean grout lines that visually expand the room. Mosaics for shower floors, feature walls, or niche accents create subtle layers of texture and interest. For comfort and a sense of indulgence, we often incorporate heated flooring systems so stepping out of the shower onto a warm floor becomes part of your daily ritual. Proper substrates and waterproofing are always used to ensure these finishes stand the test of time.

Fixtures & Lighting

High-end fixtures and thoughtful lighting separate an average bathroom from a true spa experience. We work with brands known for quality and design, pairing rain showerheads, handheld wands, wall-mounted faucets, and smart toilets or bidet seats to match your style and expectations. Layered lighting plans may include recessed ceiling lights, decorative sconces, backlit or anti-fog mirrors, and dimmable circuits to set different moods throughout the day. Every switch, outlet, and fixture location is planned for both beauty and practicality.

Small Bathroom Solutions

Not every project is a large master suite—but every bathroom deserves good design. For smaller baths, guest suites, and powder rooms, we focus on smart space planning and visual tricks that make the room feel larger. Wall-hung vanities, floating toilets, glass shower doors, wall niches, and well-placed mirrors can dramatically open up tight spaces. Even in compact rooms, we incorporate high-end materials and details so they still feel luxurious, not like an afterthought.


Our Bathroom Remodel Process

Design & Material Selection

We begin with a design consultation to understand how you use your bathroom today and what you want it to become. Together, we define the layout, select tile, vanity style, fixtures, cabinetry, countertops, and lighting that reflect your design preferences—modern, transitional, or classic. We also plan ahead for specialty items like stone slabs, custom glass, and premium fixtures so they’re ordered early and ready when needed. Throughout, we follow industry-best waterproofing standards and proven systems to ensure your new bathroom is as durable as it is beautiful.

Demolition & Rough-In

Our team carefully protects surrounding areas before demolition begins, then methodically removes existing finishes, fixtures, and outdated plumbing or electrical components. Once the room is open, we re-route or upgrade plumbing lines for new fixture locations and bring electrical up to current code, including GFCI circuits and dedicated lines for features like heated floors or towel warmers. Attention in this phase is critical—especially in wet areas—so we take extra care to build a reliable backbone for the new bathroom.

Installation & Finishing

After rough-ins pass inspection, we install backer boards, waterproof membranes, and any specialty substrates needed to protect against moisture. Then come the visible layers: tile setting, slab installation, cabinetry, countertops, and trim, followed by plumbing and lighting fixtures and custom glass shower enclosures. We obsess over the details—from clean miters and aligned grout joints to solid, wobble-free mounting of every accessory. The bathroom comes together step by step into the spa retreat you imagined.

Final Inspection & Cleanup

Before we call your bathroom complete, we test everything thoroughly. Toilets are flushed, drains checked, water pressure verified, and all fixtures inspected for leaks and proper operation. We also verify ventilation performance to keep humidity under control long-term. After a detailed clean and final touch-ups, we walk through the space with you, review how everything works, and answer questions about care and maintenance. The result is a pristine, move-in-ready bathroom you can enjoy immediately.


Why Trust Calwest with Your Bathroom Remodel

Expert Problem-Solving

Bathrooms often hide surprises—water damage, aging plumbing, or framing issues revealed once walls are opened. With decades of experience, our team knows how to diagnose and correct underlying problems properly rather than covering them up. We address these issues as part of the project plan so your beautiful new bathroom is built on a sound, long-lasting structure.

Efficient, Realistic Timelines

We understand that being without a bathroom—especially a primary suite—is disruptive. A typical high-end bathroom remodel might range from 4 to 8 weeks once construction begins, with larger or more complex master baths taking longer due to custom glass and specialty materials. We sequence work efficiently, coordinate trades, and communicate clearly about the schedule so you know what to expect. Our priority is to move quickly without cutting corners on waterproofing or quality.

Premium Quality & Waterproofing

Some of the most serious bathroom issues come from shortcuts behind the tile. We use proven waterproofing systems, appropriate backer boards, and correctly sized ventilation to protect your home from moisture problems. Every shower pan, niche, and penetration is detailed with long-term performance in mind. This approach appeals to homeowners who want peace of mind that their investment is protected for years to come.

Aesthetics and Everyday Function

We look at bathrooms through both a design and usability lens. That means aligning fixtures and finishes with your desired style while also thinking through water pressure, storage, cleaning, and daily routines. We consider everything from where towels will hang to how far doors and drawers swing, ensuring your spa-like space is also practical. Beautiful design is even better when it makes life easier.

Clean, Respectful Crews

Bathroom remodels happen inside the most personal areas of your home. Our team treats these spaces—and the paths leading to them—with respect, protecting flooring, containing dust as much as possible, and cleaning up at the end of each day. You’ll see professional conduct on site and consistent communication off site, so you feel comfortable with the people working in your home.

  • What is the average cost of a bathroom remodel?

    Costs vary depending on size, complexity, and level of finish, but in the Silicon Valley market a high-end hall or guest bathroom remodel often starts around the mid-five figures. Larger master bathroom renovations with custom showers, freestanding tubs, premium tile, and luxury fixtures can range significantly higher. During our consultation process, we develop a detailed scope and line-item estimate so you understand how each design choice affects the bathroom remodel cost. Our goal is to align your wish list with a clear, realistic budget.

  • How long does a bathroom renovation take?

    A typical bathroom renovation might take 4–6 weeks of active construction for a standard space, while a complex master suite with extensive tilework and custom glass can extend to 8–10 weeks. Lead times for special-order materials and inspections also influence the schedule. We’ll provide a timeline tailored to your project and keep you updated as we progress through each phase so there are no surprises.

  • Do I need to provide the fixtures or will you?

    Most clients prefer that we manage the entire procurement process, from fixtures and faucets to tile, cabinetry, and accessories. We help you select products that fit your style and budget, then coordinate ordering and delivery so everything arrives when needed. If you have specific items you’d like to provide—such as a custom light fixture or a unique freestanding tub—we can often incorporate them, as long as they’re compatible with the design and schedule.

  • Can you add a new bathroom or expand an existing one?

    Yes. We frequently convert underused areas, closets, or portions of larger rooms into new bathrooms, as well as expand existing baths for more space and function. When your goals require adding square footage or reconfiguring part of the home, we can integrate your project with our Home Additions services to create the space you need. From planning new plumbing lines to final tile and fixtures, we handle every step.

  • What popular luxury bathroom features should I consider?

    Many homeowners are excited about features like steam showers, radiant heated floors, towel warmers, smart toilets or bidets, built-in sound systems, and LED backlit mirrors. Thoughtful storage solutions, custom vanities, and layered lighting are also high on the list. During design, we’ll review trending and timeless options and help you prioritize the features that best fit your lifestyle, budget, and long-term plans.

  • Will you handle permits for my bathroom remodel?

    Yes. In cities like Redwood City, Menlo Park, and Atherton, bathroom remodeling that involves moving plumbing, updating electrical, or modifying structural elements typically requires permits. Calwest manages permit applications, plan submissions, and required inspections for plumbing, electrical, and building work. You get a compliant, documented project without having to navigate the process yourself.
