Waterfall Kitchen Island: 10 Marble and Quartzite Slabs

A waterfall kitchen island is an island where the countertop slab does not stop at the edge: it turns down at one or both ends and runs to the floor, so the veins continue across the corner and down the side. The island becomes one block of stone. Below are ten marble and quartzite slabs from our range shown on islands like this, from white Calacatta to gray, beige and green, with finish, thickness and the uses each one is listed for.

All of them are sold by the slab and priced by quote. As of October 2026, our range lists 388 marble slabs, 178 of them in white marble slabs, and 177 quartzite slabs in quartzite slabs; every stone is in stone slabs. For varieties, bookmatching and how batches work, see our guide to marble slabs.

Waterfall countertop and waterfall edge island: what the terms mean

A waterfall countertop, a waterfall edge island and a waterfall island all describe the same look: the countertop slab turns down at the end of a counter and runs to the floor. On a flat island the stone ends at the edge of the top and the cabinets show below. On a waterfall island the slab turns down to the floor and the veins continue across the corner, so a line that crosses the top keeps going down the end panel. With two ends, the top and both sides form an arch over the cabinets. A full-slab island adds the long front panel too, so the island is stone on three or four sides.

Two vein looks show up in the photos below. On a continuous-vein waterfall the lines on the end panel run on from the top without a jump, as on Skyline and Le Blanc. On a bookmatched panel two slabs mirror each other, so the veins meet in a V, as on the Vecchia Antico backsplash and the Bora Bora island front.

White marble waterfall islands

1. Calacatta Cremo Delicato Ext, polished

Cremo Delicato Ext has a cream white ground crossed by long bands of gold, taupe and soft gray that run in waves. In the photo below it is in a galley kitchen with charcoal cabinets, on the island top, the perimeter counter and the full-height wall behind the cooktop. It is listed for countertops, interior walls and shower walls.

2. Calacatta Lincoln, polished

Calacatta Lincoln is a bright white marble with fine gold-gray lines that cross the slab on the diagonal. The photo shows a waterfall end that drops straight to the floor next to the stools, and the same marble on the back wall up to the open shelves. It is listed for countertops, interior walls and shower walls.

3. Namib Gold, polished

Namib Gold is a white marble with wide, sweeping bands of sand, taupe and pale gray that run on a slant. In the photo the slab wraps the front of the island and its end, so the bands travel across the whole block, and the backsplash behind is the same stone, with light oak floors and linen curtains. It is listed for countertops and shower walls. More are in white slabs.

White quartzite

4. Le Blanc quartzite, polished

Le Blanc is a white quartzite with thin, dark gray veins that branch across it. The island in the photo has a waterfall at both ends, and the dark lines pass over each corner and down to the terrazzo floor. The wall behind the ovens is clad in the same slab. It is listed for countertops, interior walls and shower walls.

Gray, blue-gray and taupe

5. Skyline, polished

Skyline has wavy bands of charcoal, gray and white. The photo shows an island with a waterfall end and a stone front panel; the waves run along the front and turn the corner onto the end without a break. The backsplash behind the range is Skyline too, with light oak cabinets around it. It is listed for countertops, interior walls and shower walls, and it is one of the stones in gray slabs.

6. Vecchia Antico, polished

Vecchia Antico mixes blue-gray and white with bold amber lines. In this kitchen the backsplash behind the range is two slabs set as a mirrored pair, so the amber lines meet in a V. On the island the slab drops down the waterfall end, and the amber streak on the top continues down the side, next to brown wood cabinets. It is listed for countertops and interior walls.

7. Bora Bora quartzite, polished

Bora Bora is a pale gray-taupe quartzite with dark veins and a few green streaks low on the slab. This is a full-slab island: the stone runs down the front and both ends, and the dark veins form a wide V across the front panel. Bora Bora is listed for countertops and interior walls.

Soft beige

8. Taj Mahal Supreme quartzite, honed

Taj Mahal Supreme is a soft white-beige quartzite with light taupe waves. Honed, it has a matte surface with a low sheen. The island in the photo is wrapped in it on the top and both ends, against fluted walnut cabinets, and the back wall shows the same stone with its waves in a chevron. This honed slab is listed for countertops, interior walls and shower walls. Other matte stones are in honed slabs.

Green

9. Oasis Maestro quartzite, polished

Oasis Maestro swirls sage green, sand, cream and a touch of peach. The kitchen in the photo uses it everywhere: a waterfall island, the perimeter counters, the backsplash and the range hood, with white oak cabinets and cream stools. It is listed for countertops and shower walls. More green stones are in green slabs.

10. Vivid Green quartzite, polished

Vivid Green is a deep green quartzite with lighter green and white bands. The photo shows a peninsula: the slab turns down the end and runs along the front, and the bands line up across the corner. Behind the faucet is a green herringbone tile, with white cabinets on either side. It is listed for countertops, interior walls and shower walls.

Marble or quartzite for a waterfall island

Both are natural stone sold by the slab, and nearly every slab of either kind in our range is listed for countertops. Marble is a calcite stone; quartzite is sandstone that turned to solid quartz. The figures below are from our range as of October 2026.

	Marble slabs	Quartzite slabs
Slabs in our range	388	177
Listed for countertops	376	175
Thickness	193 at 3 cm, 195 at 2 cm	156 at 3 cm, 21 at 2 cm
Finishes, by count	Polished 267, honed 92, leathered 11, others	Polished 125, honed 21, leathered 15, textured 15

In this list	Cremo Delicato Ext, Lincoln, Namib Gold, Skyline, Vecchia Antico	Le Blanc, Bora Bora, Taj Mahal Supreme, Oasis Maestro, Vivid Green
Browse	Marble slabs	Quartzite slabs

In short, marble in our range leans white and gray and is split evenly between 2 cm and 3 cm, while quartzite runs wider in color, with green and blue groups, and comes mostly at 3 cm. More on the two stones is in quartzite vs marble.

Polished or honed on a waterfall

The finish is the same on the top and the end panels. Polished stone has a glossy, reflective surface; honed stone is matte with a low sheen. Nine of the ten slabs above are polished and one, Taj Mahal Supreme, is honed. Finishes are compared in our guide to polished, honed and leathered stone.

2 cm or 3 cm on a waterfall end

On a waterfall island the thickness shows as the line at the top corner where the slab turns down: about 1 1/4 inch for a 3 cm slab and 3/4 inch for a 2 cm slab. This list has four slabs at 2 cm and six at 3 cm. See 3 cm slabs, 2 cm slabs and 2 cm vs 3 cm countertop slabs.

Putting the kitchen together

The set below keeps to one warm palette. The island slab is white with gold veins, the backsplash tile is a cream travertine in small 2 3/4 by 5 1/2 inch pieces, and the floor is a pale oak plank. For more tile behind a stone counter, browse kitchen backsplash tiles and kitchen floor tiles.

Waterfall Kitchen Island FAQ

Is a waterfall countertop only for islands?

No. The same turn-down can finish a peninsula, the end of a perimeter run or a bar. In this list, the Vivid Green photo shows it on a peninsula that meets the wall, and Calacatta Lincoln shows a single waterfall end beside the stools. Any slab listed for countertops can be used, and the end panel is the same stone as the top.

Does a waterfall island use more stone than a flat island?

Yes. Each waterfall end is extra slab area, about as tall as the island and as deep as the top, and a front panel adds more. The quote request on each slab page has a field for the approximate square footage of the project and one for your fabricator's name, so the quote can be based on the whole island.

Can I see the actual slab before I order?

Yes. Each slab's product page lists its available batches, each with its own photo, size, number of slabs and warehouse. For a waterfall island, those batch photos show how the veins run across the slab you would get. The request form also lets you ask for a slab sample of the stone you are considering.

Can the backsplash match the waterfall island?

Yes, when the stone is also listed for interior walls. Several kitchens in this list do it, among them Skyline, Le Blanc and Calacatta Lincoln, with the island stone running up the wall behind the range or the ovens. As of October 2026, 324 of our marble slabs and 152 of our quartzite slabs are listed for both countertops and interior walls.
