Bathroom Countertop Installation Cost
Replacing your bathroom countertop starts with choosing the right material, size and sink configuration. As a budgeting guide, a standard quartz or granite vanity top may cost approximately $550–$900 installed for a single sink, or $750–$1,200 or more for a double sink.

Replacing your bathroom countertop starts with choosing the right material, size and sink configuration. As a budgeting guide, a standard quartz or granite vanity top may cost approximately $550–$900 installed for a single sink, or $750–$1,200 or more for a double sink.
The final price depends on the countertop dimensions, material, thickness, edge profile, sink cutouts and installation requirements. A backsplash or side splash, removal of the existing countertop, cabinet preparation and plumbing reconnection can also affect the total.

How Much Does Bathroom Countertop Installation Cost?
A bathroom countertop is not priced by square footage alone. Measuring, fabrication setup, transportation and installation involve fixed costs, so a small vanity top may still carry a minimum project charge.
The table below provides approximate budgeting ranges for standard quartz or granite vanity tops. Areas are calculated using a countertop depth of 22 inches.
| Vanity size and sink configuration | Approximate countertop area | Estimated price including installation in GTA |
|---|---|---|
| 24–30 inches, single sink | 3.7–4.6 sq. ft. | ~$165–$255 |
| 36 inches, single sink | 5.5 sq. ft. | ~$250–$305 |
| 48 inches, single sink | 7.3 sq. ft. | ~$330–$405 |
| 60 inches, double sink | 9.2 sq. ft. | ~$415–$505 |
| 72 inches, double sink | 11.0 sq. ft. | ~$495–$605 |
Installed ranges are typical GTA market figures, not a quote. check whether each quote you compare includes it.
Bathroom Countertop Cost by Material
Color, pattern and thickness change the price even within one material . 3 cm quartz costs more than 2 cm.
| Material | Relative cost | In a bathroom | Maintenance | Best for |
|---|---|---|---|---|
| Quartz | $$ | Non-porous; resists toothpaste, makeup and hair dye. Not heat-proof. | Low | Family bathrooms, rentals, most homes |
| Granite | $$–$$$ (depends on slab) | Handles moisture when sealed; light colors can absorb cosmetic oils | Periodic sealing | A unique natural look |
| Marble / quartzite | $$$–$$$$ | Marble etches from acidic products (some cleaners, perfumes) | Sealing, gentle cleaning | Primary ensuites, powder rooms |
| Porcelain | $$$ (usually above quartz) | Very stain- and heat-resistant; needs skilled fabrication to avoid chipping | Low | Modern designs, hot-tool users |
| Solid surface / cultured marble / laminate | $ | Laminate swells where water sits at seams and the sink edge | Low–moderate | Tight budgets |
For kids’ bathrooms, quartz with rounded edges is a practical choice because it is durable, easy to maintain, and avoids sharp corners. For the primary ensuite, premium stone paired with double sinks can create a more luxurious look. In a powder room, consider using a remnant—a leftover piece from a premium stone slab—because the countertop is usually small, allowing you to upgrade the material without adding much to the overall cost. For rentals and condos, neutral quartz or porcelain is a practical, versatile choice that works well with a wide range of bathroom styles.

What Pushes the Price Up
The simplest job is a sound cabinet where the new top is the same size and the sink stays where it is. It has an undermount sink, a standard eased edge, a 4″ backsplash, and takes a few hours on site. That’s usually the lowest price you’ll see. Every change from that picture adds something.
Sinks are where it adds up first. A double vanity isn’t just more stone. It means two cutouts, two sets of faucet holes, and often plumbing work. Take a typical ensuite going from one sink to two: widespread faucets, a side splash because the vanity sits between walls, and a drain that has to move. That job lands at the upper end of the double-vanity range, with plumbing on top [CONFIRM: who does plumbing]. Shape matters too. L-shaped or wall-to-wall tops may need a seam.
The sink type also changes the cutting work:
- An undermount sink needs a precise, polished opening because that edge stays visible.
- Drop-in and vessel sinks are simpler to cut for.
- An integrated sink is part of the top itself.
Faucets work the same way. A single-hole faucet needs one hole. A 4″ centerset needs three close together, and an 8″ widespread needs three spread apart. A wall-mounted faucet moves the work into the wall, because the plumbing has to be run there. Disconnecting and reconnecting the sink is routine; moving the drain or supply lines is what costs more.
Edges and splashes are the details people usually decide last. A simple eased edge is normally included, while bevel, bullnose, ogee and mitered edges cost more. For the backsplash you can choose a 4″ stone strip, full-height stone or tile. If your vanity is tucked between two walls, don’t forget the side splash. It’s the item we see missed most often in quotes.
Removal and access round out the price. A loose laminate top comes off quickly. A glued cultured-marble top or a tiled backsplash takes longer and can damage the wall behind it. Scheduling is also affected by:
- condo elevator bookings, loading docks or set building hours
- a second-floor ensuite the stone has to be carried up to
If budget is the main concern, a prefab top costs less, though it only fits standard-size cabinets. Already bought one? Posha can install it.
What We Often Find Under an Old Bathroom Countertop
Some problems stay hidden until the old top is off, and they’re the main reason a replacement quote changes.
The most common one is the cabinet itself. Years of small leaks around the faucet can leave the particleboard on top soft or swollen. Stone is heavy and needs a solid base, so that gets repaired before anything goes on it. A cabinet that’s out of level or square is the other big one, because a stone top sitting on it can rock and eventually crack. Shims usually fix it, but a twisted cabinet may need replacing. If your vanity cabinet needs to be repaired or replaced before the new countertop goes in, you can also use Posha’s cabinet installation services.
Behind a glued backsplash we sometimes find damaged drywall or mould. Under the sink, the extra we run into most is a shut-off valve that won’t close, or that starts leaking as soon as it’s touched. Now and then the drain is at the wrong height for the new sink.
An old cultured-marble top with water damage shows how quickly these add up. Removal is slow, the cabinet usually needs repair before we can template, and both add time and cost. That’s why an honest quote for a job like this says some items will be confirmed once the top is off.
You can check some of this yourself before asking for quotes. Open the vanity doors and look under the sink. Water stains or soft spots mean the cabinet should be looked at first.

How to Save
Vanity tops are small, so they can often be cut from a remnant, a leftover piece of slab that costs less than a full one. If you’re also replacing your kitchen countertops, cutting the vanity from the same slab saves a template visit and gives you matching color.
After that, the biggest savings come from not changing what doesn’t need to change:
- Keep the sink and drain where they are.
- Keep the cabinet if it’s solid and level.
- Stick with a standard edge.
- Choose your sink and faucet before templating so nothing has to be recut.
If the vanity top is part of a bigger update, our bathroom renovation service covers the rest of the room.
One thing not worth saving on is pulling out a glued or stone top yourself. A cracked cabinet or a broken pipe will cost more than the removal fee.
Doing kitchen countertops too? Cut your vanity top from the same slab — one template visit, matching color.

Frequently Asked Questions
How much does it cost to replace a bathroom countertop in the GTA?
Typically $550–$900 for a single-sink quartz or granite top and $750–$1,200 for a double, installed, before HST. Glued old tops, cabinet repairs or plumbing changes add to that.
Is quartz or granite cheaper for a vanity?
It depends on the slab. Standard quartz and common granite often land close together; rare granite and premium quartz patterns cost more. On a vanity, labour often matters more than the material difference.
Can I keep my vanity cabinet and replace only the top?
Yes, if it’s solid, level and the right size. We check for water damage and level before templating; minor issues can usually be repaired.
Does the price include the sink and faucet?
Usually it includes the sink cutout and faucet holes, not the fixtures. Ask whether the sink is supplied and whether mounting and reconnection are included.
How long does installation take?
The on-site install is usually done the same day, often in a few hours. Templating and fabrication happen before that, so the full process takes longer.
Do I need a plumber?
Disconnecting and reconnecting the sink is part of a routine replacement. Moving drains or supply lines, replacing seized valves, or a wall-mounted faucet is extra plumbing work.
Can you install a vanity top I already bought?
Yes. We’ll check that it fits your cabinet, walls and plumbing first.
Conclusion
On a bathroom vanity, the stone is only part of the price. Templating, cutouts, removal, plumbing and the condition of the cabinet underneath are what move the final number — which is why a small top rarely matches a per-square-foot calculator. Posha handles measuring, material selection, fabrication and installation with one licensed, insured, WSIB-covered team, led by 20+ years in the natural stone industry.
