From Old Tub to New Shower: What It Really Costs in NYC & Nassau County

From Tub Trouble to Shower Smarter

Are you staring at an old tub that barely gets used and wondering if a walk-in shower would make more sense for your space? Or are you trying to figure out whether a tub-to-shower conversion actually fits your budget before you start making calls?

In this guide, you'll learn what a tub-to-shower conversion typically costs in Brooklyn, Queens, Bronx, and Nassau County — how pricing breaks down by shower type, what drives costs up or down, and which hidden expenses catch homeowners off guard in NYC's older housing stock.

By the end, you'll be able to estimate your total cost with confidence and decide whether this bathroom remodel makes sense for your home.

What Does a Tub-to-Shower Conversion Cost?

A typical tub-to-shower conversion costs between $8,000 and $15,000, covering materials and labor for the wet area. Final pricing depends on shower size, wall and door materials, plumbing changes, and upgrades like built-in seating or niche shelving.

Prime Craft Renovation approaches tub-to-shower conversions as focused wet-area remodels — allowing you to update the shower space without committing to a full bathroom overhaul when the rest of the layout still works.

Cost by Shower Type

The type of shower you choose is the single biggest variable in the final cost. Here's a breakdown of typical ranges:

Shower Door and Enclosure Costs

Glass Shower Door Pricing

Your shower door choice is one of the most visible cost drivers — glass style and hardware can escalate quickly and significantly affect the total.

You can't accurately price a shower conversion without deciding on the enclosure first. A basic framed door on a pre-fab shower stall lands at a very different number than a frameless setup on a new walk-in shower — and the hardware finish you choose matters too.

If you're planning for older adults, mobility needs, or long-term accessibility, the shower door choice matters just as much as grab bars and threshold height.

Shower Accessories and Upgrade Costs

Accessories and add-ons can be the difference between a basic conversion and a shower that feels fully customized. Each upgrade feels small — until you stack them.

Hidden and Unexpected Costs in Tub-to-Shower Conversions

This is the part of the cost conversation most homeowners miss — because you often don't know what's behind the bathtub until demolition starts. In Brooklyn brownstones, Queens row houses, and Nassau County homes built before 1980, hidden issues are more common than not.

If your existing plumbing is outdated, the shower valve needs replacement, or you're changing the drain location, these factors can quickly affect the total. In NYC co-ops and condos, this is also why a tub-to-shower conversion is a professionally-led project — board approval and licensed plumber documentation are often required before any work starts.

Additional Costs for a Tub-to-Shower Conversion

Permits

In New York City and Nassau County, most tub-to-shower conversions involving plumbing changes require permits from the NYC Department of Buildings or local municipality. Permit costs range from $200 to $2,000 depending on scope. Prime Craft Renovation manages all permitting as part of our pre-construction process.

Disposal of Old Tub and Materials

Tub removal and disposal typically runs $150 to $300. Cast iron tubs — common in older Brooklyn and Queens homes — cost more to remove due to weight and size.

Pipe Replacement or Rerouting

If existing plumbing needs changes, labor runs $45 to $200/hour. Broader plumbing upgrades can reach $300 to $2,000+ depending on what the project requires.

Mold, Mildew, or Rot Remediation

If issues are found during demolition — which happens frequently in NYC homes with years of moisture exposure — they must be corrected before installation continues. This is not an area to skip. Remediation typically runs $500 to $3,000+ depending on severity.

Factors That Impact Tub-to-Shower Conversion Cost

Shower Pan

The shower pan affects cost because it determines how water drains and how the floor is constructed. Pre-fabricated pans are less expensive and faster to install, while custom or low-threshold pans require more labor and precise work. Improper pan installation leads to leaks — this is not a step to cut costs on. Prime Craft Renovation defines the shower pan type and drainage approach in the pre-construction plan set so you know exactly what level of construction to expect.

Wall Materials

Basic wall panels install quickly and cost less, while tile showers increase labor due to surface prep, waterproofing, and grout work. Higher-end materials or full-height tile coverage raise costs further as square footage and detail increase. Prime Craft Renovation includes material and finish selections during the design process, so you understand how tile choices affect labor and total pricing before construction begins.

Enclosures and Shower Doors

A basic framed door is typically the least expensive option. Frameless glass doors and multi-panel enclosures cost more due to thicker glass, custom sizing, and more complex installation. Larger walk-in or curbless showers often require custom enclosures that are sized and sealed on site.

Faucets and Fixtures

A standard shower valve and single showerhead keep costs lower, while multiple controls, specialty finishes, or upgraded fixtures increase both material and plumbing labor. Fixture placement can also determine whether existing rough-in plumbing can be reused or must be modified.

Safety Features

Grab bars, seating, and low-threshold designs are generally affordable individually, but they add labor and coordination during installation — especially when wall reinforcement is needed for proper grab bar blocking. Prime Craft Renovation plans safety features into the construction scope early so wall framing and layout are addressed before tile goes up.

Built-In Storage

Each shower niche interrupts the wall system and adds installation time for framing, waterproofing, and tiling. The cost increase is moderate per niche but compounds when multiple storage features are included. Prime Craft Renovation documents built-in storage locations in the construction plan set so you understand how storage choices affect labor and project cost.

Questions to Ask Before a Tub-to-Shower Conversion

Is a Tub-to-Shower Conversion Worth It?

For most homeowners, a tub-to-shower conversion is worth it — it improves daily usability, accessibility, and modern style without requiring a full bathroom overhaul. Most conversions return approximately 60%–70% of their cost at resale, and the daily benefit of a shower that actually fits how you live is immediate.

For Brooklyn and Queens homeowners where bathrooms are often small and tubs go unused for years, replacing the tub with a well-designed walk-in shower is consistently one of the highest-value upgrades per square foot. In Nassau County homes where master bathrooms have more space, a larger frameless walk-in with a built-in bench and niche can significantly elevate the room.

The real value comes from planning carefully before construction starts — knowing the cost, the options, and the constraints of your specific space before demo begins.

• 01 How long does a tub-to-shower conversion take?
  Most tub-to-shower conversions take 1–2 weeks of active construction once permits are approved. The pre-construction phase — design, material selections, 3D renderings, and permitting — typically takes 4–8 weeks. In NYC co-ops and condos, board approval can add additional time before work begins.
• 02 Do I need a permit for a tub-to-shower conversion in Brooklyn or Nassau County?
  Yes — in New York City and Nassau County, most conversions involving plumbing changes require permits from the NYC Department of Buildings or local municipality. Co-ops and condos also typically require board approval and licensed plumber documentation. Prime Craft Renovation handles all permitting as part of our pre-construction process.
• 03 Will removing the tub hurt my home's resale value?
  It depends on how many bathrooms your home has. If this is your only bathroom, keeping a tub-shower combo is generally recommended for resale. If you have a second bathroom with a tub, converting a primary bathroom to a walk-in shower is unlikely to hurt resale — and often improves it. Most conversions return approximately 60–70% of their cost at resale.
• 04 What are the most common hidden costs in a tub-to-shower conversion?
  The most common hidden costs are water damage and mold remediation ($1,500–$9,000), plumbing upgrades when drain or valve locations need to change ($300–$2,000+), and cast iron tub removal in older NYC homes ($150–$300). Prime Craft Renovation reviews existing conditions during the site walk so surprises are identified before construction begins.
• 05 Can I add a walk-in shower without moving plumbing?
  In many cases, yes — if the new shower drain aligns with the existing drain location and the valve stays on the same wall, plumbing changes can be minimal. However, curbless showers and custom drain placements often require some plumbing modification. Prime Craft Renovation evaluates your existing layout during the design phase to determine what's required before pricing is finalized.
