What a stone pedestal sink does in a bathroom
A pedestal takes the place of the vanity. The column hides the drain line behind it, the floor stays visible on both sides, and the stone is on view from the front and both flanks. That puts the outside of the column on equal footing with the bowl when choosing a model. In a powder room or a guest bath it stands in full view. Freestanding basins in other stones are gathered in stone pedestal sinks in other materials, and travertine sinks shows the same material as vessels and wall hung basins.
The travertine tones on offer
Troia Light is the pale end of the group, a soft beige on an 18x18 round column, and a curved beige round and a light travertine rectangle are close to it in tone. The red travertine is warmer, with peachy rose tones. The gray piece is the cool one in the group. The brown square cone and the Noce curved model, a brown stone whose name means walnut, are the darkest, and one rectangular prism is listed in gold with cream undertones running through it.
Travertine shifts in color from one block to the next, and these listings describe moderate variation, so the photo on a product page shows the range that stone falls in, not a portrait of the sink that ships to you.
Square, round and curved designs
Square and cone profiles
The gray piece has a basin shaped like a hearth, set on a square pedestal, with an 18x18 footprint and an overall height of 33 inches. The brown sink is a square cone, 16x16 across the top, and its 36 inch overall height is the tallest here.
Round and flared columns
The red and Troia Light rounds both measure 18x18 with a 33 inch overall height, a plain cylinder beneath a round bowl. The curved beige model has a 16 inch bowl and a 33.5 inch overall height. The Noce Brown curved sink, also 33.5 inches in overall height, changes diameter along its height, from 16 to 19.5 inches, which gives it a softer silhouette than a straight cylinder.
Rectangular basins
Two designs are rectangular: the honed and filled light travertine at 15x16 and the gold rectangular prism at 14x21.5, both 33.5 inches in overall height. The prism's 14 inch side keeps it slim in one direction, which helps on a narrow wall between a door and a toilet.
Overall heights of 33, 33.5 and 36 inches
A carved pedestal has no adjustable legs or base, so the listed overall height is the height it keeps. Most of these measure 33 or 33.5 inches overall, with the brown square cone at 36. The 3 inch gap between 33 and 36 inches matters most for taller users, and that is worth weighing against who uses the room most.
Honed, filled and textured surfaces
Most of this group is honed, a matte face with low sheen that shows the stone's pores and banding. The light travertine rectangle is honed and filled, so its natural voids are closed before the surface is ground flat. The curved beige model and the gold prism are rough honed with worked exteriors, the first with a combed middle band of fine parallel grooves and the second with triangular relief cut into its column. The brown square cone is the polished exception.
One block or several carved sections
Several of these sinks are cut from a single block of travertine, including the red and Troia Light rounds, the Noce curved model and the gold prism. Others are assembled from separate carved sections: the brown square cone and the light travertine rectangle are each two blocks, and the curved beige model is three. Either way the result is solid stone, and the listings note that the floor has to be level and strong enough to carry it.
Travertine pedestal vs wall mount vs vessel
A pedestal suits a room where the sink should stand out as an object on its own. Travertine wall mount sinks also leave the floor below them clear, while travertine vessel sinks are bowls made to sit on a counter or vanity. The same freestanding idea in veined stone is in marble pedestal sinks.
