Westfield, NJ's Bathroom Renovation Contractor for One-Stop Remodels
A bathroom remodel touches nearly every trade in your home, from plumbing and electrical to tile, cabinetry, and finish carpentry. When those trades are handled by different companies, the gaps between them are where most remodeling headaches start.
SEI Construction, Inc. keeps every trade under one project manager from the first design sketch through the final walkthrough, so your vision stays intact and you always know exactly who to call with a question.
Homeowners comparing contractors for bathroom work often find a wide range of experience levels and communication styles, and we’ve built our reputation in Westfield over nearly four decades by showing up, staying in contact, and finishing what we start.
Every bathroom remodel here begins with an in person consultation at your home, not a phone estimate, so the plan we build together actually fits your space.
Our Westfield, NJ Bathroom Renovation and Remodeling Services
Primary Bathroom Remodels & Renovations
Your primary bathroom sees more daily use than almost any other room, so the difference between a good bathroom remodeling contractor and a great one shows up in details most homeowners never think to ask about, like where the exhaust fan vents or how the shower pan slopes. SEI Construction, Inc. has been the bathroom remodel company Westfield homeowners return to for primary suite renovations because we plan for how the space will actually be used, not just how it will photograph on day one. Craftsmanship, storage, and a design that fits your routine matter just as much as the finishes you see first.
Kids' Bathroom Remodels & Renovations
A kids’ bathroom remodel has to survive daily wear from toothpaste splatters to bath time chaos, which is a different design challenge than most bathroom renovation projects. As a bathroom renovation company that’s worked in Westfield homes for nearly 40 years, SEI Construction, Inc. designs kids’ bathrooms that hold up now and adapt easily as your children grow. It’s one of the home improvement projects families notice paying off the longest, since a well planned space rarely needs a second remodel a few years later.
Powder Room Additions and Renovations
Powder rooms are compact, but that makes every design choice more visible, from the vanity to the lighting to the wallpaper. Many bathroom remodel companies treat a powder room like an afterthought squeezed between larger projects, but SEI Construction, Inc. gives it the same design attention as a full primary bath. Bathroom remodel or addition work in a small footprint still needs the same permitting, plumbing precision, and finish quality, we just apply it to a smaller canvas with an outsized visual impact.
Basement Bathroom Additions & Renovations
A basement bathroom comes with challenges a main floor bathroom never faces, from moisture management to drain line routing to whether the space even has the depth for a standard trap and vent setup. This is where a lot of general contractors run into trouble, since basement plumbing rarely follows the straightforward paths of an upstairs bath. SEI Construction, Inc. has added basement bathrooms in Westfield homes for decades, so as your bathroom home improvement partner, we already know what a Westfield basement is likely to throw at us before we open a wall.
Above Garage Bathroom Additions for Guest Suites
Above garage spaces have become one of the most requested guest suite additions in Westfield, since they add real living space without touching your home’s main footprint. A bathroom in this kind of addition has its own set of considerations, from tying into existing plumbing stacks to keeping the layout efficient in a smaller, angled floor plan. Not all bathroom remodel companies take on above garage work, since it blends bathroom design with the structural and framing knowledge of a full addition. SEI Construction, Inc. handles both under one roof, so your guest suite bathroom gets the same attention to detail as the rest of the space, comfortable, functional, and built to feel like it’s always been part of the house.
Build-Up & Bump-Out Bathroom Additions
A build-up or bump-out addition is often the most efficient way to gain the square footage a proper bathroom needs, especially in older Westfield homes where interior space is already spoken for. Rather than sacrificing a bedroom or hallway to expand a cramped bathroom, we extend outward or upward to create the room a full renovation actually calls for. This is more involved than a typical bathroom remodel in Westfield, NJ, since it touches your home’s structure and exterior, not just the interior finishes. If you’re looking for a contractor for bathroom remodel work that includes structural changes, SEI Construction, Inc. manages the framing, roofing, and exterior tie-ins alongside the plumbing and design, so the addition looks and performs like it was part of the original build.
Comprehensive Bathroom Design & Remodeling Services
A bathroom remodel and a bathroom renovation cover different ground. A remodel usually means reconfiguring the space itself, moving plumbing, changing the layout, or expanding the footprint. A renovation typically means updating what’s already there, new vanities, tile, and fixtures within the existing layout. Most bathroom home improvement projects fall somewhere between the two, and at SEI Construction Inc., we combine design expertise with skilled craftsmanship to deliver bathrooms that are as functional as they are beautiful regardless of which one your project turns out to be.
Whether you’re envisioning a spa-like primary bath, a stylish powder room, or a practical basement bathroom, we tailor every design to your home, lifestyle, and budget. If you have a concept in mind but aren’t sure how to move forward, our team will help refine your vision with expert guidance every step of the way, one reason homeowners searching for contractors for bathroom work in Westfield tend to stay with us through the full project rather than shopping around mid-way.
We begin with an in-person consultation to understand your goals, take precise measurements, and discuss layout possibilities, the same first step every bathroom renovation contractor should start with, though not all of them do. From there, we create a detailed 3D rendering, similar to what you see on today’s top home renovation shows, so you can visualize your new bathroom before construction begins.
Next, we guide you through material selections, including cabinetry, countertops, flooring, tile, and lighting that align with your preferred aesthetic, whether modern, transitional, farmhouse, or custom. Our design-build approach ensures every choice balances beauty, function, and long-term value, and it’s the same process whether you’re planning a full bathroom remodel in Westfield, NJ or a more contained update.
From the first consultation to the final reveal, SEI Construction makes the process seamless and transparent. Unlike bathroom remodel companies that subcontract out the finish work, we handle every stage ourselves, so nothing gets lost between crews. The result is a bathroom that enhances both your home and your everyday living experience.

See How We Can Help
A great bathroom remodel comes down to the details you touch and see every day. Across Westfield and Union County, SEI Construction, Inc. has built bathrooms around the specific features homeowners request most, and we bring the same design and construction expertise to every one of them.
Walk-In Showers
A curbless walk-in shower opens up a bathroom visually and makes the space easier to use for years to come. We build each one around a proper zero-threshold entry and a linear drain, keeping the floor slope subtle and flush rather than pitched to a center point, then finish it with one of a kind shower tile, a built-in niches for storage, and framed or frameless glass to complete the look.
Custom Bathroom Vanities & Cabinetry
We build custom bathroom cabinetry and vanities sized to your space, with storage planned around how you actually get ready in the morning and countertops that give you the workspace you need while complementing your bathroom’s design. Cabinet finishes, hardware, sink style, vanity backsplash tile, and mirror placement are all chosen together, so every detail feels like part of one design rather than a list of separate selections.
Soaker Tubs
A deep soaker tub turns a bathroom into a place to unwind after a long day. We fit freestanding and built-in soaker tubs into primary bathroom renovations, working the tub into your floorplan with details like a waterfall faucet or whatever inspiration you bring to the table.
Tub to Shower Conversions
On the opposite end, many Westfield homeowners are moving away from a tub they never use in favor of a larger, more accessible shower. A tub to shower conversion is one of our most requested updates, and we handle the shower design, tile selection and installation, plumbing, and waterproofing as one complete job.
Bathroom Tile Design
Tile does more work than almost any other material in a bathroom, setting the tone for the whole room while also handling moisture and daily wear. Large format porcelain creates a clean, seamless look, classic subway tile brings a timeless feel, herringbone and other patterned layouts add a custom touch, zellige tile brings handcrafted texture and depth to accent walls, and natural stone look tile in showers or elsewhere rounds out a spa like finish. We do all this and more.
Bathroom Flooring
The right bathroom floor has to hold up to moisture and daily use without sacrificing style. Porcelain tile remains the most popular choice for its durability and range of finishes, luxury vinyl plank offers a warmer look with strong water resistance, natural stone brings a high end, organic feel, and radiant heated flooring adds comfort underfoot in primary and basement bathrooms alike. We help you choose the right floor for your space and design.

What Makes SEI Construction, Inc. Different From Other Bathroom Remodel Companies
Choosing a bathroom remodel company is as much about what happens after the contract is signed as it is about the design itself. Here’s what sets SEI Construction apart once the work actually begins:
Detailed Bathroom Project Proposals
Every project starts with an itemized, written proposal that spells out the full scope and cost before any work begins. No rough estimates that grow once demolition starts, and no surprise change orders for work that should have been scoped from day one.
Quality Bathroom Construction & Craftsmanship
SEI Construction holds an A+ rating with the Better Business Bureau and was named a Remodeling Big50 winner, a national recognition given to only 50 remodeling contractors in the country each year. Both reflect a standard of work we hold ourselves to on every bathroom, not just the ones that make it into a portfolio.
Bathroom Remodel Warranties
A finished bathroom should perform as well as it looks five years in, not just on the final walkthrough. We stand behind our craftsmanship after the project wraps, so you’re never on your own if something needs a second look.
