River Stone Pedestal Sink 22"x19"x35" (57x49x90 cm) — RSP250904

Volcanic Stone Pedestal Sink (Riverstone) — Hand-Carved — Monolithic Piece — 57 x 49 x 90 cm (22 x 19 x 35 in) | RSP250904

The RSP250904 Natural Volcanic Stone Pedestal Sink is a true work of natural art, a monolithic functional sculpture hand-carved from a single solid block of volcanic stone (basalt) imported directly from Southeast Asia (Indonesia). With a 57 x 49 cm (22 x 19 in) basin, 90 cm (35 in) overall height and an impressive weight of 320.95 kg (708 lb), this freestanding pedestal sink is one of the most commanding and monumental pieces in the entire Marmer Butik collection. It needs no vanity top, cabinet or any supporting furniture; it is installed directly on the floor, with the plumbing connection running beneath the base. The column and basin are carved from a single piece of solid volcanic stone, with no seams or joints, revealing the strength and raw beauty of nature in its most sophisticated form. Every pedestal is absolutely one of a kind; its textures, veining, pores and tones are natural and unrepeatable. There is no replica and no industrial standard: no one else in the world owns a piece like yours.

One of the freestanding pedestal sinks most specified by architects and interior designers for the very highest-end projects.

Solid Volcanic Stone — Strength, Texture and Presence

The volcanic stone used in this pedestal has singular characteristics that set it apart from any other material: a slightly porous surface, deep tone and organic texture that bring personality and presence to the space. Formed as volcanic magma cooled at temperatures above 1,100°C (2,012°F), it is one of the densest and most resistant stones on the planet, which explains this piece's extraordinary weight.

The extraction of volcanic stone depends on nature and is limited; each block is unique, and the carving process respects the stone's natural forms. Specialized artisans carve each pedestal by hand, in a tradition that carries centuries of technique, culture and respect for the raw material. This makes every pedestal a collector's piece, exclusive, rare and impossible to reproduce.

Finish — Organic Exterior and Polished Interior

What sets Marmer Butik's Riverstone pedestal sinks apart is the contrast between the sculptural rawness of the exterior and the refined functionality of the interior. The exterior preserves the raw, organic texture of the volcanic stone, with its irregular surface, natural pores and deep tone; every curve and irregularity tells the rock's geological story. The interior of the basin is hand-polished, resulting in a smooth, satin surface that is easy to keep clean.

Along the 90 cm (35 in) column, the organic texture of the volcanic stone creates a visual effect of monumental sculptural presence; the piece commands the space like a natural column that seems to have been shaped by the Earth itself. More than a sink, it is a functional sculpture for projects that call for personality, authenticity and natural luxury.

Which Faucet Goes with This Pedestal Sink?

Because this is a freestanding pedestal sink 90 cm (35 in) tall, choosing the faucet calls for special attention to the type of installation:

• Wall-mounted faucet (recommended): The height of the pedestal favors this installation, allowing the spout to be positioned at the ideal height in relation to the basin.
• Wall-mounted single-handle mixer: A clean, sophisticated look that enhances the sculptural presence of the pedestal.
• Floor-mounted faucet: Creates an elegant, contemporary visual effect; the faucet rises from the floor beside the pedestal, forming a sculptural pairing of great impact.
• Ceiling-mounted faucet: For bolder projects, a contemporary option that surprises.
• Ideal finishes for dark volcanic stone: Matte black, brushed gold, copper or brushed stainless steel, creating a sophisticated contrast with the deep tone.

Care and maintenance of the pedestal

• Daily cleaning: A soft cloth with water and mild soap; never use acids, bleach or abrasives.
• Dry after use: Avoid standing water to preserve the polished finish and prevent stains on the exterior.
• Annual sealing: Apply a sealer made for natural stone once a year.
• Avoid oily substances: Creams, oils and makeup can stain; wipe them off immediately.
• Do not use rough sponges: Choose soft cloths to avoid scratching the polished interior.
• Avoid strong impacts: Despite the high strength of basalt, heavy objects can cause cracks.

Expert Tip: Because this is an exceptionally heavy piece (hundreds of kilograms), the pedestal sink requires structural planning in advance. The floor should be assessed by an engineer or architect to make sure it can safely bear the concentrated load; reinforced concrete floors or a reinforced slab are the most suitable. Handling and installation should be carried out by a specialized team with proper equipment. To keep the "living" look of the volcanic stone, apply a sealer formulated for natural stone every 6 months, paying special attention to the 90 cm (35 in) outer column.
