You wake up to a bathroom that works. The shower pressure stays consistent, storage makes sense where you need it, and everything fits where it should.
Your daily routine becomes smoother instead of a series of workarounds. No more jiggling handles or stepping around that loose tile you’ve been meaning to fix for months.
When friends visit, you’re not making excuses about outdated fixtures. When it’s time to sell, buyers see quality work that adds real value to your Mastic Beach home.
Corsino Construction Corp has been handling bathroom renovations across Mastic Beach and Suffolk County since 2000. We understand the quirks that come with older Long Island homes—the plumbing that doesn’t quite line up, the tight spaces, the permit requirements.
We’re licensed, insured, and we actually return phone calls. Our crews show up when we say we will, and we finish what we start. Most of our work comes from referrals because homeowners see what we do for their neighbors.
You can check our work in bathrooms throughout the area. We’re the contractors other contractors recommend when their own family needs work done.
First, we come look at what you’re dealing with. We measure everything, check the plumbing and electrical, and talk through what you want to change. You get a written estimate that covers everything—no “we’ll figure it out as we go” pricing.
Once you’re ready to move forward, we handle the permits and order materials. We protect the rest of your house before we start tearing anything out.
Demo comes first, then rough plumbing and electrical work gets updated to code. New subfloor goes in if needed, then tile work, fixtures, and finishing touches. We clean up our mess and walk through everything with you before we consider the job complete.

Your bathroom renovation includes complete demolition and removal of old materials. We handle all the rough work—plumbing updates, electrical modifications, and proper waterproofing that prevent future problems.
Many Mastic Beach homes built between 1940-1990 need plumbing updates to handle modern fixtures and improve water pressure. We work with what’s still good and replace what needs replacing, giving you a bathroom that functions properly without unnecessary costs.
We also address common Long Island issues like humidity control with proper ventilation fans and moisture barriers. Your new bathroom will look great and function properly for years in our coastal climate.
Bathroom renovation costs in Mastic Beach typically range from $15,000 to $35,000 for a complete remodel, depending on size, materials, and complexity. Basic updates with standard fixtures start around $12,000, while high-end renovations with custom tile work and premium fixtures can reach $45,000 or more.
The biggest cost factors are plumbing relocations, electrical upgrades, and material choices. We provide detailed written estimates so you know exactly what you’re paying for before any work begins.
Yes, most bathroom renovations in Mastic Beach require permits from Suffolk County, especially if you’re moving plumbing, adding electrical circuits, or making structural changes. Even some cosmetic work needs permits if it involves removing walls or changing ventilation.
We handle the permit application process and coordinate required inspections. Skipping permits might save money upfront, but it creates problems when you sell your home and can result in expensive corrections later.
Most bathroom renovations take 2-3 weeks from start to finish, depending on the scope of work. A basic refresh with new fixtures and finishes might take 10-14 days, while a complete gut renovation with plumbing and electrical updates typically takes 3-4 weeks.

Absolutely. We understand bathroom renovations disrupt your daily routine, so we work with you to minimize the impact. We can often leave you with a functioning toilet and sink overnight, especially during the first few days.

We provide a comprehensive warranty on all bathroom renovation work, covering both labor and materials for one full year after project completion. This includes everything from tile installation and fixture mounting to plumbing connections and electrical work.
We also help coordinate any manufacturer warranties on fixtures, vanities, and other components we install. If something isn’t right, we come back and fix it. Most issues that arise are minor adjustments that we handle quickly at no charge.
Yes, we specialize in working with older Mastic Beach homes built between 1940-1990. We understand the quirks that come with these houses—plumbing that doesn’t quite line up, spaces that aren’t perfectly square, and the permits that need to be pulled correctly.
It’s common to discover issues like old water damage, outdated wiring, or plumbing problems once we open up walls. We stop work immediately and show you what we found before proceeding, explaining your options and providing pricing for any additional work needed.
