Year of Establishment2026 Bathroom Pricing By Scope
Three Scopes. Three Different Budgets.
Bathroom remodels are priced based on what you're changing, not square footage.
Tier 1 and Tier 2 ranges below assume a three-piece bathroom (one tub/shower combo, one toilet, one vanity).
Four-piece configurations, expansions, and new baths are priced separately.
01
Tier 1 · Direct Replacement
$20K - $28K
Your bathroom layout works, but everything behind the walls needs to go: new plumbing, new fixtures, and new tile throughout.
3-5 Weeks
02
Tier 2 · Reconfigured Layout
$23K - $33K
The bathroom stays in the same location, but the fixtures are repositioned for a better layout within the existing footprint.
6-10 Weeks
03
Tier 3 · Full Carve-Out or Net-New Addition
Pricing by plans
Creating a new bathroom from scratch is a fundamentally different project than renovating an existing one.

Before You Start
Why Bathroom Costs Vary So Much on Long Island.
"Bathroom remodel" is a phrase that covers three very different projects. Swapping out fixtures in an existing three-piece is not the same job as relocating a shower, and neither of those is the same as building a new bathroom out of a closet or hallway.
The scope determines the structural work, the trades involved, the permit path, and the timeline. This guide breaks bathroom projects into three clear tiers so you can ground your budget in real numbers before you invest in design, and know exactly where your project falls before you sit down with a contractor.
In 2026, a three-piece bathroom remodel on Long Island typically runs $18,000 to $30,000 installed: $20K to $28K for a direct replacement and $23K to $33K for a reconfigured layout. Carving a new bathroom out of non-bath space starts around $30,000 and routinely runs $50K+, depending on structural, plumbing stack, and egress work. Moving fixtures, tile tier, and frameless glass are the three biggest cost levers.
"Every bathroom looks the same once the tile goes in. The budget difference is almost entirely in what you can't see, where the plumbing went, what had to be done behind the walls, and whether a permit was required to get there."
Evan Lewitas · VP, Center Island Contracting
Tier 1 · Up to 5' × 10' · Three-piece
Direct Replacement
The footprint and layout work, no walls move and no fixtures relocate. We gut the bathroom down to the framing, then rebuild it correctly from the inside out: upgraded insulation, electrical, plumbing, and venting first, followed by new drywall, tile, trim, exhaust, and lighting. Everything you see is new. So is everything you can’t.
Tier 1 · Typical 2026 Range
$20k-$28k
Approx. Homeowner Cost
| Construction (labor + materials we supply) | ≈ $16k - $20k |
| Client-supplied fixtures, tile & finishes | ≈ $4K – $8K |
| Total installed cost to homeowner | ≈ $20k-$28k |
Timeline:
Permit:
3-5 Weeks
Permit often not required
Tier 2 · Existing footprint · Three-piece
Reconfigured Layout
You keep the bathroom where it is, but the fixtures lay out differently.
You keep the bathroom where it is, but the toilet, vanity, or shower move. That means new supply and waste lines, new electrical routing, and more demolition through wet walls and floors. The finish scope is the same as Tier 1, with more complexity underneath.
Tier 2 · Existing footprint · Three-piece
$23K – $33K
Approx. Homeowner Cost
| Construction (labor + materials we supply) | ≈ $19K - $25K |
| Client-supplied fixtures, tile & finishes | ≈ $4K - $8K |
| Total installed cost to homeowner | ≈ $23K - $33K |

Before a Wall Comes Down
Permit Processing on Long Island Adds 6–10 Weeks To Your Timeline.
It surprises homeowners every time. If your project needs a permit, and Tier 2 and Tier 3 always do, add two-plus months to your calendar before construction begins. Our quoted timelines start from permit approval, not from contract signature.
Why This Matters at Resale
Some Renovations Improve Your Home. This Changes Your Home Listing Price.
On Long Island, a one-full-bath home is a compromised asset. Buyers price it that way. A second full bathroom, whether carved out of existing square footage or added through a dormer, changes the category the home competes in. It’s not an incremental improvement. It’s a reclassification.
The same logic applies to the primary ensuite. A home with a shared hall bath and no private bath off the primary is priced like a starter home, regardless of what else was renovated. Adding that ensuite, even in a modest footprint, removes an objection that no staging or landscaping can fix.
01
One bath → Two
A one-bath listing competes against starter homes. A two-bath listing appears alongside larger homes in your town.
02
No ensuite → Ensuite
A primary bedroom without a private bath is priced as incomplete. An ensuite, at any size, resolves that.
03
Cosmetic alone
A fresh tile job on a bath that was already functional returns less than people expect. The bones matter more than the finish.
Tier 3 · New square footage or repurposed space
Full Carve-Out or Net-New Addition
A bathroom where there wasn't one before.
Typical 2026 Range
Creating a bathroom from scratch, carving it out of a closet, a hallway, or an addition, is a different project. Structural, venting, egress, and layout all come into play. We’ve had clients spend $30K, $40K, $50K, or more. We can’t give you a definitive number until we develop plans, but the range below from real projects should calibrate your thinking.

What Drives The Cost Of A Bathroom Remodel
Ten factors that move your number.
Two bathrooms of the same size, in the same Long Island town, can produce budgets $15,000 apart. These ten decisions explain why.
01
High
Moving Plumbing
Fixture relocation adds $4K–$10K minimum. Crossing a joist bay or going through a slab costs more.
02
High
Frameless Shower Glass
Enclosures run $3,500–$7,000 installed. Niches, benches, and linear drains are additive.
03
High
Tile Selection Tier
Builder ceramic vs. large-format porcelain vs. natural stone is not a small delta. Stone installation alone adds 30–40% in labor.
04
Medium
Vanity
Stock to semi-custom to fully built-in ranges from $2K to $12K+ depending on size and finish.
05
Medium
Radiant Floor Heat
$1,500–$3,500 depending on square footage. Worth every dollar in a primary bath.
06
Medium
Steam Shower
$4K–$8K for the generator and controls alone, before the tile envelope it requires.
07
High
Venting a New Bath
No existing chase means cutting through the roof. Not optional per code.
08
Medium
Window or Egress
Any modification to an existing bathroom opening requires additional framing, possibly structural work.
09
High
Four-Piece vs. Three
Separating tub and shower adds plumbing rough-in, tile area, and glass. Flag as a scope change from base.
10
High
Permit Processing
Long Island permit processing adds 6–10 weeks before a wall comes down. Build it into your timeline.
