  • Mid-range full bath: ~$25,000–$40,000+ (most common range for Long Island families)

• The average bathroom remodel on Long Island is often quoted in the mid-teens to high-20s for standard projects, with Suffolk County averages around $16,500 and Nassau County around $18,500, scaling higher for more complex work.

What Counts as a “Full Bathroom Renovation” on Long Island?

Homeowners often use “bathroom remodel” to describe everything from new paint and a faucet swap to a full gut renovation. For cost planning, it helps to define terms.

A full bathroom renovation typically includes:

• Removing existing fixtures and finishes (tub/shower, vanity, toilet, tile, flooring, lighting, trim)
  
• Updating plumbing and electrical as needed
  
• New tub or shower (or a custom shower system)
  
• New tile or wall surround, plus flooring
  
• New vanity, countertop, faucets, toilet, lighting and fan
  
• Patching, painting and trim work 

Elite Bathroom’s full bathroom renovation services cover:

• Full gut remodels (back to studs, re-framing where needed)
  
• New-construction bathrooms that are already framed and roughed in but need all finishes installed
  
• Replacement of windows, doors, fan vents and flooring as part of the bathroom scope
  

If you are only replacing a tub or shower insert with a new KOHLER® LuxStone system or installing a single walk-in tub, that’s closer to a one-day tub or shower project, not a full bathroom renovation—those costs and timelines are different, and we’ll touch on them later.

2025 Full Bathroom Renovation Cost Ranges on Long Island

Because Long Island has a mix of older capes, ranches and newer builds, costs vary—but the market data points to reasonably consistent bands.

Small or Hall Bathroom (Full Remodel)

Smaller bathrooms (think a 5×7 hall bath) that still get a true full remodel—new tub or shower, tile, flooring, vanity, toilet and lighting—often land in the range of:

~$15,000–$25,000+ in 2025, depending on materials and whether plumbing is moved.

These projects usually:

• Keep the layout roughly the same
  
• Use quality but not ultra-luxury materials
  
• May include a new tub/shower combo, basic tile and a mid-range vanity
  

Average Full Bathroom in a Typical Long Island Home

For a standard full bath (not tiny, not a huge primary suite), cost studies and contractor data for Long Island show many mid-range remodels landing between:

~$25,000–$40,000+, with some projects hitting the low-20s and others stretching above 40k when upgrades stack up.

These usually include:

• Full demo
  
• New tub or shower (or a KOHLER® LuxStone shower)
  
• Tile on walls and floors
  
• New vanity, countertop, toilet, fixtures and lighting
  
• Moderate plumbing/electrical upgrades
  

High-End or Large Primary Bath

For large primary bathrooms or high-end projects with:

• Custom tile work and niches
  
• Freestanding tub plus separate shower
  
• Heated floors
  
• Premium cabinetry and stone surfaces
  
• Layout changes and significant plumbing/electrical work
  

…it’s realistic to budget:

$40,000–$75,000+ on Long Island, similar to other high-cost New York markets.

These numbers can feel wide, but they reflect very different scopes. The next section explains what actually drives price.

7 Main Factors That Drive Bathroom Renovation Cost

1. Size and Layout

Larger rooms simply require more tile, flooring, paint, fixtures and labor, which drives cost. But even a small room can be expensive if you:

• Move plumbing fixtures significantly
  
• Change wall positions
  
• Add built-in storage or custom niches
  

A basic “rip-and-replace” in a small hall bath costs less than a layout change in a bigger primary bath.

2. Scope: Cosmetic Refresh vs Full Gut

A surface-level refresh (paint, faucet, maybe a new vanity) is one price point; a full gut renovation down to studs is another.

Full gut projects allow issues like water damage, rot, mold or outdated wiring to be properly addressed—but they also require more labor and materials. New York cost guides note that full renovations consistently land above simple cosmetic updates in price, even when room size is similar.

3. Materials and Finish Level

Finishes can swing a budget significantly:

• Tile: ceramic vs porcelain vs natural stone
  
• Shower system: prefabricated vs KOHLER® LuxStone vs fully custom tile
  
• Countertops: laminate vs quartz or natural stone
  
• Fixtures: basic chrome vs designer lines and specialty finishes
  

Industry cost data shows mid-range remodels using good quality but not ultra-luxury materials often land in the $25,000–$40,000+ bracket on Long Island, while luxury finishes push projects into the higher bands.

4. Plumbing and Electrical Changes

Keeping the toilet, vanity and shower roughly where they are is generally more economical than relocating plumbing stacks, drains or venting.

Likewise, older homes may need:

• GFCI protection upgrades
  
• New circuits for heated floors or additional lighting
  
• New exhaust fan vented to the exterior
  

These upgrades add cost but are critical for safety and code compliance.

5. Permits and Local Requirements

Long Island, like the rest of New York, has permit and inspection requirements that vary by municipality. Cost guides for New York remodels note that permit fees and related administrative costs contribute to higher regional averages compared with the rest of the country.

Your contractor should:

• Pull the correct permits
  
• Schedule inspections
  
• Build to current code, not just “how it was built before”
  

6. Existing Conditions and Surprise Repairs

Once walls and floors are opened up, contractors often uncover:

• Water damage behind tile
  
• Rotten subfloors
  
• Outdated or unsafe wiring
  

These repairs are sometimes non-negotiable and can add to the final cost. Seasoned remodelers build a contingency buffer into estimates and timelines for exactly this reason.

7. Contractor Experience and Coordination

Experienced, full-service bathroom remodelers manage:

• Design guidance and selections
  
• Permits and inspections
  
• Scheduling of all trades (demo, framing, plumbing, electrical, tile, finish carpentry, painting)
  
• Clean-up and final punch list
  

This coordination helps keep projects on schedule and reduces the risk of costly mistakes or re-work. Elite Bathroom operates as a full-service bathroom remodeling company, providing design support and professional installation by a licensed, insured, KOHLER®-trained team.

How Long Does a Full Bathroom Renovation Take on Long Island?

Homeowners are just as concerned about time as they are about money.

Across contractor timelines and renovation guides, a consistent pattern emerges:

• Hands-on construction for a full bathroom renovation: typically 3–6 weeks, sometimes up to 8 weeks for complex primary baths.
  
• Full project timeline (including design, selections, ordering materials and permits): often 6–10+ weeks, depending on lead times and municipal processes.
  

A typical sequence looks like:

1. Consultation & Design (1–3 weeks) 
   • In-home visit
     
   • Measurements and photos
     
   • Discuss needs, style and budget
     
   • Preliminary layout and selections 
2. Pricing, Approvals & Permits (1–3 weeks) 
   • Final proposal and contract
     
   • Permit applications where required 
3. Materials Ordering (2–4 weeks) 
   • Ordering fixtures, tile, cabinetry, glass and specialty items
     
   • Waiting for products to arrive at the warehouse 
4. Demolition (1–3 days) 
   • Remove old tub/shower, vanity, flooring, walls as needed
     
   • Haul away debris 
5. Rough Plumbing & Electrical (3–7 days) 
   • Adjust drains, supply lines, venting and wiring
     
   • Install or adjust fan vent 
6. Tile, Flooring & Walls (1–2 weeks) 
   • Waterproofing
     
   • Tile installation and grouting
     
   • Install flooring and baseboards 
7. Fixtures, Vanity & Trim (3–7 days) 
   • Set tub or shower system
     
   • Install vanity, countertop, toilet and faucets
     
   • Install lights, mirrors and accessories 
8. Final Punch List & Clean-Up (a few days) 
   • Address small adjustments
     
   • Final clean
     
   • Walkthrough with the homeowner 

Working with a company that focuses specifically on bathroom remodeling, like Elite Bathroom, helps streamline this entire sequence under one roof.

Design Choices That Deliver the Most Value Over Time

Not every upgrade has the same impact. Some choices dramatically improve everyday use and long-term value.

Prioritize the “Wet Area”

Designers consistently suggest spending where water lives:

• Tub or shower system
  
• Waterproofing
  
• Tile and glass
  

Whether you choose a fully tiled shower or a KOHLER® LuxStone system, this is where durability and proper installation matter most for both comfort and resale.

Lighting and Ventilation

Good lighting and proper ventilation are essential, not optional:

• Layered lighting: overhead, task lighting at the mirror, and if possible, accent lighting
  
• A correctly sized and properly vented fan to protect against moisture damage
  

These upgrades support health, safety and long-term durability, often at a relatively modest cost.

Storage and Layout

Bathrooms feel more luxurious when everything has a place:

• Deep vanity drawers instead of just doors
  
• Recessed medicine cabinets
  
• Built-in niches in the shower
  
• Thoughtful toilet placement that doesn’t dominate the view
  

Thoughtful layout adjustments can radically improve how the room functions without always requiring huge structural changes.

Aging-in-Place Features

Many Long Island homeowners choose to install:

• Low-threshold or curbless showers
  
• Built-in benches
  
• Grab bar blocking in walls
  
• Comfort-height toilets
  
• Non-slip tile
  

These features extend the usable life of your bathroom for you and your guests and can reduce the need for costly modifications later.

When Is a One-Day Tub or Shower Replacement Enough?

A full bathroom renovation is not always necessary to achieve your goals.

A one-day tub or shower replacement may be the smart play when:

• The rest of the bathroom is in decent condition
  
• You primarily dislike or struggle with the tub/shower area
  
• You want to upgrade to a LuxStone shower or walk-in tub for accessibility without redoing the entire room.
  

In those cases, Elite Bathroom can:

• Replace your old tub or shower with a KOHLER® LuxStone system
  
• Install a KOHLER® Walk-In Bath for improved safety and hydrotherapy
  

These projects generally cost less than a full renovation, keep more of your existing finishes and can often be completed in as little as one day for the wet area itself.
