Why Remodel Your Bathroom?
A bathroom remodel is one of the most personal investments you can make in your home. It's the first room you walk into in the morning and the last one you use at night — and when it doesn't feel right, you notice. Whether your bathroom feels cramped, dated, or simply never matched your style, a thoughtfully designed renovation can change how your entire day starts and ends.
Beyond daily comfort, bathroom renovations consistently rank among the highest-return remodeling projects in Oakland County. Updated primary suites, spa-inspired tile showers, and custom vanities with quality fixtures add meaningful value to your home while improving your quality of life today.
Our Bathroom Remodeling Services
Primary Suite Bathroom Renovations
Our primary suite renovations are among our most involved and most satisfying projects. We work with Oakland County homeowners to create bathrooms that feel like genuine retreats — walk-in showers with multiple spray systems, freestanding soaking tubs, radiant heated floors, custom double vanities, and handcrafted tile work that turns a functional room into something you actually look forward to using.
Guest Bathroom Remodeling
Guest bathrooms get more use — and more scrutiny — than homeowners often expect. We redesign and rebuild guest baths that feel polished and intentional, with quality fixtures, smart storage, and finishes that hold up to heavy use without looking utilitarian.
Powder Room Redesigns
Powder rooms are one of the highest-impact, lowest-footprint renovations you can do. A small space with the right tile, a custom vanity, and thoughtful lighting can become one of the most memorable rooms in your home. We've done powder rooms throughout Oakland County that stop guests in their tracks.
Walk-In Shower Conversions
Converting a standard tub-shower combination into a custom walk-in shower is one of our most requested bathroom remodeling services. We design curbless entries, custom tile surrounds, built-in niches, frameless glass enclosures, and multi-function shower systems that make a dated bathroom feel completely new.
Custom Vanities & Storage
We design and install custom bathroom vanities built specifically for your space — your ceiling height, your plumbing rough-in, your storage needs. Floating vanities, furniture-style pieces, double-sink configurations, and built-in linen storage are all part of what we do.
Tile & Flooring
Tile is where bathroom personality lives. We install large-format floor tile, custom mosaic patterns, handmade zellige, natural stone, and full wet-area tile surrounds. Our tile work is precise, detailed, and built to last — which is why it's one of the most complimented aspects of every bathroom we complete.
Accessible Bathroom Design
We specialize in accessible bathroom remodeling that doesn't look clinical. Curbless showers, strategically placed grab bars, wider doorways, comfort-height vanities, and non-slip flooring — all designed to improve safety and function for every member of your household without sacrificing the aesthetic integrity of the space.
Full Bathroom Renovation & Construction
From demolition and waterproofing through tile, fixtures, vanity, lighting, and final finishes — we manage your complete bathroom renovation as a single, coordinated project. One team, one timeline, one point of contact.
Our Signature Finishes
Costello & Co is known throughout Oakland County for a level of finish detail that goes beyond what most remodeling contractors offer. Our team has expertise in natural stone fabrication and installation, custom plaster and microcement finishes, handmade tile sourcing and installation, and European-inspired bathroom design — all of which show up in our completed bathrooms in ways that are hard to replicate with standard materials and methods.
If you've seen our portfolio and wondered how we achieve those finishes, the answer is a combination of skilled tradespeople, carefully sourced materials, and a design team that sweats every detail from grout line width to fixture finish.
