One carved block or stacked pieces
This page has two kinds of construction, and the product descriptions say which is which. The Carrara White conical design (16.5 x 16.5 x 36 in), the Lilac and the GMStone white are listed as carved from a single block, so the basin and the column are one continuous piece of stone and the veining runs from the rim to the floor without a break. The Verde Antico is a single round column with the basin carved into its top.
Others are made in parts. The round black marble sink (20 x 33.5 in) is a basin resting on a tapered column, two solid pieces in total. The Toros Black oval (17 x 20 x 33.5 in) is built the same way, an oval basin on a tapered column, and the black conical sink (16 x 36 in) and the Turkish white square cone (16 x 16 x 36 in) are also two blocks. The Toros Black and Carrara White (16 x 16 x 36 in) goes further with three blocks: black at the top and the base, a white column between them. A stacked stone pedestal sink can combine two marbles or two finishes in a way a single block cannot.
Heights between 33 and 36 inches
Sizes on this page follow one pattern: W x L x H in for square and rectangular tops, and D x H in for round ones, where H is the listed height. On a pedestal, H is the overall height of the piece, floor to rim, so it is also the working height at the basin. The Calacatta Viola and fluted Carrara White designs are 18 x 18 x 33 in, the curved white marble sink is 22 x 34 in, the wide Calacatta Viola is 20 x 30 x 34 in, and the GMStone white is 16 x 16 x 36 in.
The same column idea in a warmer stone is in travertine pedestal sinks.
Round, square and sculpted outlines
Round pedestals are the largest group: a cylinder, a bowl or a cone on a column, with diameters from 16 to 22 inches. Square forms take a stricter line, such as the Turkish white square cone and the square prism of the Toros Black and Carrara White. The Toros Black oval sets a 17 x 20 in polished black bowl on a column that narrows toward the top. The wide Calacatta Viola is a stand-alone piece that combines the marble with wood, 20 x 30 x 34 in, and it has the largest top here.
Fluted and combed columns
Some columns are textured. The fluted Carrara White has vertical grooves cut into its column, while the black conical sink pairs a polished basin with a rough, combed column. The Toros Black and Carrara White has a rough, hand-worked exterior under a polished top, and the GMStone white combines a honed bowl with a combed texture on its column.
Which stones come as pedestal sinks
Carrara White and white Turkish marble give the classic soft gray vein on white. Calacatta Viola adds gray and violet veining to a white ground on the 18 inch round, while the wide 20 x 30 piece shows bold gray and charcoal streaks, and Lilac shows purple, gray and white together. Verde Antico, sold here as a 16 inch column, is a deep green stone with white veining. The black models range from a solid polished black to the two-tone Toros piece. For basins in the same stones without a column, see Calacatta Viola sinks and black marble sinks.
Where a pedestal fits
A pedestal leaves the floor visible around its base, which is why it often ends up in powder rooms, guest baths and narrow bathrooms where a vanity would fill the space. A 16 x 16 in footprint is the smallest here; the 20 x 30 in Calacatta Viola asks for a wider wall. With no cabinet, the drain and supply lines come from the wall behind the sink or up through the floor, and the listings describe planning their position so they stay out of sight so they stay mostly out of sight. On the slim Verde Antico column, the listing treats visible supply lines as part of the look.
Pedestal, wall mount or vessel
These three options differ in what holds the basin. A pedestal stands on the floor, a wall mount sink hangs from the wall, and one of the vessel sinks rests on a counter. The wider range of carved basins is in marble sinks, and the column form in other materials is in pedestal sinks in other materials.
