Cost by scope
| Scope | Typical cost | What it includes |
|---|---|---|
| Prefab single vanity top | $450 – $1,000 | A stock molded top with an integrated bowl for a single vanity — BathCalculator prices a single 6 sq ft vanity in cultured marble at $240–$480 for the counter itself, with setting, sealing and reconnect bringing a real installed total into this band |
| Standard custom or double vanity top | $1,300 – $2,200 | Where most cultured marble projects land: a made-to-measure top, most often a double vanity — Angi puts a standard cultured marble installation at $1,280–$2,180 with an average of $1,850, and BathCalculator prices a double 11 sq ft vanity at $440–$880 for the counter before custom sizing and fitting |
| Shower or tub surround, or a large custom top | $2,200 – $3,200+ | The same molded material as wall panels: Angi's cultured marble guide covers shower and tub surrounds in the same project family at the top of and above its standard band, and RemodelingExpense prices custom molded vanity work to $2,280 for 12 sq ft before surround panels |
Where the money goes
| Part of the job | Share | Note |
|---|---|---|
| Molded cultured marble top & fabrication | 45–55% of total | The cast piece itself — marble dust and resin molded with its gel-coat finish and, usually, its sink bowls cast in. Angi prices cultured marble at $30–$100 per sq ft by size and complexity, and BathCalculator at $40–$80 installed for the counter |
| Installation labor | 25–35% | Setting a one-piece molded top is faster than slab work — the piece arrives finished — but it must be levelled, bedded and sealed at every joint, and a surround adds panel-setting time on top |
| Backsplash, edges & faucet drilling | 5–15% | The matching backsplash and sidesplash pieces, a decorative edge profile (a named price driver in Angi), and drilling the faucet spread the top was not molded with |
| Removal, prep & plumbing reconnect | 5–10% | Taking out the old top, the site preparation Angi itemises — demolition of old surfaces, plumbing adjustments and cleanup — and reconnecting the faucets and drains to the new bowls |
What moves the price most
Prefab or custom-molded is the cultured marble budget. A stock top is a shelf product — BathCalculator prices the counter itself for a single vanity at $240–$480 — while a made-to-measure piece is cast for your vanity, and Angi's standard installation band of $1,280–$2,180 is mostly that custom work. Scope is the second lever: this material's real project family is the bathroom, not the kitchen — vanity tops first, then shower and tub surrounds in the same molded panels, and each added surface moves the project up a tier rather than up a few dollars. The integrated bowl is the quiet saving: sinks cast into the top remove the separate sink, its cutout and its rim seal from the quote, which is part of why cultured marble undercuts natural marble so heavily (Angi's marble guide prices cultured marble at $65 per sq ft in its type table, against $180 for Calacatta). Finally, the gel coat is the upkeep line: the surface is non-porous and needs no sealing — the maintenance trade is gentler cleaning instead, because abrasive cleaners dull the coat that makes the piece waterproof.
Worked example: how a typical cultured marble countertop budget breaks down
A typical job: a custom-molded cultured marble top for a double vanity, bowls cast in, matching backsplash, faucets drilled and fitted, old top removed and plumbing reconnected. The budget below totals $1,850 — the "most homeowners pay around" figure from the top of this page — split using this page's own cost breakdown. It shows how a real quote at that level is usually composed; every line is built from the ranges on this page, and it is an illustration, not a quote for your project.
| Line item | Example budget |
|---|---|
| Custom-molded cultured marble top | $925 |
| Setting, levelling and installation labor | $555 |
| Backsplash, edge profile and faucet drilling | $185 |
| Old top removal, prep and plumbing reconnect | $185 |
| Total | $1,850 |
What most people get wrong
- Ordering a prefab top against rough measurements — a molded piece cannot be trimmed like a slab; a top cast or bought a half-inch wrong is a return, not a fix.
- Cleaning the new top like real stone — abrasive cleaners dull the gel coat that makes cultured marble waterproof; the care rule is gentle cleaners only, from day one.
- Comparing a cultured marble quote with a natural marble quote by the total — the molded piece includes its bowls and needs no sealing, while the slab quote is carrying cutouts, a separate sink and a sealing line.
- Skipping the cabinet levelling — a one-piece molded top stressed across an uneven vanity is how cracks start, and a cracked-through top is a replacement, not a repair.
Costs in your city
Cultured marble pricing follows the regional casting shops: the tops are molded products, often made within driving distance, so metros with several cultured-marble fabricators price custom work keenly and turn it around fast, while markets served by one shop or by shipped-in product pay more and wait longer. Prefab tops from home centres flatten the difference — a stock single-vanity piece costs much the same anywhere — so the local spread lives in the custom tier. Ask each bidder whether the top is cast locally or shipped, and what the lead time is; on a molded product, that answer is most of the schedule and much of the price.
Frequently asked questions
How much does a cultured marble vanity top cost?
About $1,300–$2,200 installed is the typical band on this page for a standard custom or double vanity top, with most projects landing around $1,850 — Angi's average for a standard cultured marble installation. A prefab single top prices well below it, at $450–$1,000 installed.
How much does cultured marble cost per square foot installed?
Angi puts cultured marble at $30–$100 per sq ft depending on size and complexity, and BathCalculator at $40–$80 installed — the standard-project overlap is $40–$80. RemodelingExpense prices small custom vanity work higher, to $190 per sq ft, because a 12 sq ft top carries the same templating and fitting as a larger one.
What is cultured marble, and how is it different from real marble?
It is a cast product — marble dust bound in resin, molded to shape and finished with a gel coat — not a quarried slab. That is why it can be molded with its sinks and backsplash as one piece, why it costs a fraction of natural marble, and why it never needs sealing: the gel coat is non-porous where real marble is not.
Does cultured marble need sealing or special care?
No sealing — the gel-coat surface is non-porous, which is the material's main practical advantage over the natural marble it imitates. The care rule runs the other way: avoid abrasive cleaners and scouring pads, which dull and scratch the gel coat, and the waterproof surface is gone with it.
Can cultured marble be repaired if it cracks or stains?
Small gel-coat chips and dull patches are usually repairable by a refinishing specialist, and minor staining lifts from a non-porous surface in a way it never would from real marble. A cracked-through top is a replacement, not a repair — which is why the setting bed and levelling in the install quote matter: a molded piece stressed on an uneven cabinet is how cracks start.
