Tub-to-Shower Conversion in New Rochelle, NY
Free quotes for tub-to-shower conversion in New Rochelle, NY.
A tub to shower conversion in New Rochelle, NY removes an alcove tub, such as the 60-inch model Kohler calls an industry-standard size, and builds a shower in its footprint, and in this city it is plumbing work under the City Code from the first day, because the drain, trap and valve all change. Most homeowners who give up a tub do it for the shower: in Houzz's 2025 study, 82% of those who removed a tub used the space to enlarge the shower. The valve rises from tub height to shower height, the drain changes size, and the floor becomes a sloped, waterproofed receptor that is flood-tested before any tile is set.
Typical published range
$1,689 to $9,008 per conversion (Angi, New York City, 2026)
Remodeling magazine's 2025 Cost vs Value report has no stand-alone conversion, but its universal-design bath removes the tub and installs a curbless, tiled walk-in shower with a thermostatic mixing valve as part of a whole-room job; that project costs $47,052 in the New York, NY metro, $46,763 across the Middle Atlantic and $42,183 nationally. For the conversion alone, Angi's July 2026 New York City page lands at $3,378 on average, with most projects from $1,689 to $9,008; its line items include plumbing modifications at $800 to $3,500, waterproofing at $500 to $2,500 and total labor at $1,500 to $5,000. Angi's New York City shower page lists plumbers at $150 to $250 an hour, a billing rate that covers overhead, insurance and profit; the wage behind it, in the State Labor Department's Hudson Valley figures, averages about $84,583 a year. Publication 862 treats installing a tub or shower enclosure as a capital improvement, while replacing only a faucet or shower head is a taxable repair.
The conversion is specified from the drain up. New Rochelle's plumbing chapter lists a 1-1/2-inch trap for a bathtub and 2 inches for a shower stall (City Code section 242-12A(1)), so the tub's drain is rebuilt at the shower size. The valve becomes shower-only: Kohler's rough-in drawing for one pressure-balancing valve gives 48 inches for a bath/shower installation against a 72-inch minimum and 78-inch maximum for shower-only work, so the wall behind it is opened. The valve meets ASSE 1016, and a WaterSense head flows no more than 2.0 gpm, against the federal 2.5. The floor is a sloped receptor, waterproofed and tested before tile, and the glass is tempered and permanently marked, as NKBA's guidelines require for every tub or shower enclosure.
Plumbing permits in New Rochelle follow City Code Chapter 242. Only a master plumber registered with the City's Plumbing Inspector, on a Westchester County certificate of qualification, may receive the permit (section 242-6); that plumber files a notification card before work starts (section 242-7B), with drawings whenever a new soil, waste or vent line is proposed. The new piping stays uncovered until it is inspected and tested, and once the final test passes the Plumbing Inspector issues a certificate of approval, without which regular use of the plumbing is prohibited (section 242-10F). The building permit runs in parallel with the plumbing filing, and our guide to the City's plumbing and building permits sets out both. The glass waits for finished tile, and Basco quotes 7-10 business days to make a custom door once the order is final.
Older bathrooms change the demolition. In New Rochelle 75.9% of housing units were built in 1979 or earlier, the nearest Census bin to the EPA's 1978 line, and under the EPA's lead rule demolition of painted surfaces is covered regardless of square footage, so the six-square-foot minor-repair exception does not apply when the plaster around a tub comes out. The same walls need an asbestos survey first if the house's construction began before January 1, 1974. Ground-floor and basement bathrooms near the Sound raise a flood question: Ida's remnants brought a federal disaster declaration for Westchester County in September 2021, and in a mapped flood zone City Code section 111-34B(3)(a) requires new and replacement plumbing connections to sit two feet above the base flood elevation, or one foot above the highest flood of record, whichever is higher.
To price a conversion we need to see the tub wall, the access panel behind the valve if there is one, and the ceiling below the bathroom. We then specify the receptor, the valve, the drain size and the glass in writing, and the contract gives you until midnight of the third business day after signing to cancel, as General Business Law section 771 requires. Prices are set against the published conversion and remodel costs.
Signs it is time to trade the tub for a shower
A conversion answers how the room is used as much as what is worn out. Look for these conditions in the bathroom you are thinking of converting; together they make the case for a shower in the tub's place, and the last one decides whether the house can spare the tub at all.
- A tub that is only ever used as a shower, with a curtain that leaves water on the floor after each use.
- Stepping over the tub wall has become hard; among Houzz's 2025 respondents addressing aging in place, 61% chose grab bars and 55% nonslip flooring.
- A fiberglass or acrylic surround that is cracked, stained or yellowed, or caulk at the tub that molds again within weeks of being replaced.
- A spray that weakens when the diverter is pulled, or a tub spout that keeps running while the shower is on.
- A second tub elsewhere in the house, which leaves this bathroom free to become shower-only without losing a bath for children or guests.
Valve, trap and vent: the plumbing behind a tub-to-shower conversion
Three pieces of plumbing change when a tub becomes a shower. The first is the valve. ASSE 1016 covers three types of shower valve, pressure-balancing, thermostatic and a combination of the two, and each has a limit stop the installer sets, usually at 120 degrees F. ASSE's scald data show why: on adult skin, a third-degree burn takes 1 minute at 120 degrees F but 5 seconds at 131 and 2 seconds at 140, while ASSE notes that tank storage should be at least 135 to 140 degrees F to limit bacteria. The tub spout goes, and with it the diverter.
The second is the trap. The model plumbing code's fixture-unit table rates a bathtub at 2 drainage fixture units on a 1-1/2-inch trap and a shower flowing up to 5.7 gpm the same, but a shower above 5.7 gpm at 3 units on a 2-inch trap, and New Rochelle's own table lists 2 inches for any shower stall. The third is the vent and the branch it joins. A 2-inch trap arm may run 8 feet to its vent where a 1-1/2-inch arm is held to 6, both pitched 1/4 inch per foot, and City Code section 242-12D(1) keeps sink wastes out of bath wastes, so the lavatory beside the new shower keeps its own fitting on the main soil or waste line. That route is drawn on the plumbing plan, the document the Plumbing Inspector reviews, before demolition starts.
The shower pan: liner and mortar bed, or a sheet or liquid membrane
The floor of a tiled shower is a receptor that must hold water until it drains, and the TCNA Handbook gives two families of method. In the traditional one, method B415, a liner sits under a mortar bed, and water that passes through the tile and grout runs along the liner to weep holes at the drain, a water in-water out system. The liner needs a pre-slope beneath it, which Oatey's guide pours at 1/4 inch per foot toward the drain; the model code requires the lining itself to fall at a 2-percent slope to the weep holes and forbids nails or perforations less than 1 inch above the finished threshold (P2709.3), and Oatey staples only within the top 1/2 inch of the liner. In the newer methods, B421 and B422, a waterproof membrane covers solid backing under the entire tiled area and connects to a drain with an integrated bonding flange, such as Schluter's KERDI-DRAIN with its 2-inch outlet.
Either way the receptor is filled and watched. The model code's test, P2503.6, fills the floor to not less than 2 inches at the threshold and holds it for at least 15 minutes with no leakage, and one Michigan county's code summary adds that an inspector must witness it; Oatey asks for at least two hours on its own liner test. Tile goes down only after the test passes, which is why a tiled conversion takes days rather than one.
Safety glass at the opening: tempering, labels and door swing
Glass beside a tub or shower is a hazardous location in the building code. Section R324.4.5 of the model code behind New York's 2025 Residential Code treats glazing in walls, enclosures or fences facing a tub or shower as hazardous where its bottom edge is less than 60 inches above a standing or walking surface, and the federal standard, 16 CFR Part 1201, covers shower doors and enclosures, with two impact classes tested at 150 and 400 foot-pounds. The marking is permanent. The National Glass Association lists the methods, acid etched, sandblasted, ceramic fired, laser etched or embossed, or a label that cannot be removed without destroying it, and NKBA's guidelines require enclosure glass to be tempered or an approved equal and marked as such.
Hinged doors open outward under NKBA's Guideline 16, and the swing must clear the toilet and the vanity. Measuring waits for finished tile: Basco's guide warns that a wall out of level by 3/8 inch or more may need a tapered filler for framed and semi-frameless doors. Published prices for those two types: HomeGuide puts a framed door at $400 to $1,100 installed and a semi-frameless one at $500 to $1,550, and Angi's New York City shower page gives $675 to $1,520 for a shower door. Frameless and low-iron glass, its thickness and its lead times are covered on the walk-in shower page.
Convert this tub, keep it, or plan the shower for access
Houzz's 2025 study shows how renovating homeowners split: 34% upgrade their bathtub, 26% keep the existing one and 25% remove it altogether. The choice turns on how the room is used, how many tubs the house has and who will use the shower in ten years.
Convert to a tiled shower
The tub comes out, the drain and valve are rebuilt, and a tested receptor and tempered glass go in. A 60 by 30-inch alcove becomes a shower that meets the code's 30-inch minimum depth, though NKBA recommends 36 by 36 inches where the room allows. Our walk-in shower page covers curbless and low-curb floors in detail.
Keep the tub and update it
With one tub in the house, or a child who bathes, keeping it in place may serve better; the tub can be refinished or replaced in the same alcove with a new surround, valve and glass, and the drain keeps its 1-1/2-inch trap. Our bathtub replacement page compares refinishing, liners and new tubs.
Convert with access in mind
A conversion is the moment to plan for later years: NKBA's access standards call for thresholds of 1/4 to 1/2 inch, blocking in the walls for grab bars rated to 250 lbs, and a hand shower on a hose at least 59 inches long. NAHB's 2025 survey ranks curbless showers second among remodelers' aging-in-place projects, after grab bars. See our accessible bathroom page.
Questions
Tub-to-Shower Conversion FAQs
How much does a tub to shower conversion cost?
Nationally, Angi averages $3,000 within $1,200 to $15,000, and HomeAdvisor's normal range is $1,500 to $8,000. HomeGuide gives $2,000 to $12,000 and itemizes a shower pan at $500 to $3,500, a glass door at $400 to $1,900, plumbing at $500 to $1,100 and a shower valve replacement at $225 to $575. The upper ends are tiled custom showers, $3,500 to $15,000 in HomeGuide's and HomeAdvisor's tables. In New York City, Angi's figures run from $1,689 to $9,008 for most projects.
Can a tub be converted to a shower in one day?
A one-day conversion is an acrylic, liner-style system set over the old footprint, which HomeGuide prices at $1,200 to $9,500. A tiled conversion cannot be finished in a day, because each layer has a cure or a test: the receptor is flood tested before tile, thin-set cures at least 24 hours before grout, and the new plumbing must be inspected before it is covered. HomeGuide puts a shower remodel at 3 to 7 days once materials are delivered, with the glass ordered only after the tile is in.
What happens if there is damage under the old tub?
The cost guides price what demolition can uncover. Angi puts a bathroom subfloor replacement at $120 to $400 nationally and water damage repair in New York City at $4 to $10 per square foot, and Fixr prices a subfloor replacement discovered under tile at $1,500 to $1,650. We list those conditions on the estimate as unit prices, so a repair found under the tub is priced before it is done rather than after.
Can the window in my tub wall stay inside the new shower?
Often it can, with the right glass. A window inside a shower stall is outside the federal glazing standard, 16 CFR Part 1201, so the building code governs it: under section R324.4.5 of the model code behind New York's 2025 Residential Code, glazing facing a shower whose bottom edge is less than 60 inches above the shower floor is in a hazardous location and must carry a safety-glazing mark. The sill and jambs are waterproofed with the walls. A window that cannot meet the rule is replaced or moved before tile.
