Sicilian Grey Solid Marble Pedestal Sink

41 hand-crafted monolithic Sicilian Grey marble pedestal sinks for a hotel project in City of Industry, California — from quarry block to container loading.

Project Overview

Forty-one Sicilian Grey monolithic pedestal sinks, several carved from each block

MARC-No-3 was a custom production run of 41 monolithic solid-stone pedestal sinks commissioned by a U.S. design firm for the Waller Creek hotel project. Each unit was CNC-routed and hand-finished as a monolithic one-piece pedestal sink from Sicilian Grey marble — several sinks were carved from each 2.8 × 1.8 × 1.6 m block, and the 41 sinks required several blocks in total — combining a polished integrated basin with a natural split-face exterior. Our account manager went to the factory to verify dimensions and details on-site at every critical stage.

What made this project complex

Precision Hole Alignment

Faucet and drain holes had to be drilled into the raw block before shaping. A positioning error would mean scrapping an entire unit. The team used physical templates and multiple photo reviews with the client to lock in coordinates.

Weight Reduction Without Weakening

Each unit is a monolithic piece carved from the block, making them extremely heavy. The architect specified specific internal zones where stone could be removed to reduce weight — but the walls had to remain thick enough for structural integrity and cleat mounting.

Z-Cleat Engineering

Recessed Z-cleats had to be routed into the back of each unit at a precise height, within an 8" zone, while avoiding the faucet channel and compromising the wall thickness. Clear did was capped at 100mm.

Dual Finish Consistency

The polished basin/deck and natural split-face exterior had to meet along a clean, consistent line across 41 units — each with natural stone variation. Maintaining that edge at scale required skilled hand-finishing.

Wood Leg Integration

The pedestal sink had to cover all tops of the wood base legs, which inserted into the stone for security. Cutouts were oversized per the sample, and the stone had to rest flat on the leg structure without rocking.

Export Packaging

Each unit was individually foam-cradled and packed in a wooden crate, then steel-strapped inside a 20' container. No damage was reported on arrival.

Communication

Direct updates, careful decisions

Throughout the project, technical questions were answered with marked-up drawings, factory photos, and short videos. A few representative moments (client details confidential):

Clear Production Flow
We need to drill all the holes first — please confirm hole positions quickly or the ready date may be delayed.

We explained why each approval mattered and what would happen next, so the client always understood the timeline impact.

On-Site Verification
I went to the factory this morning. Please see attached pictures.

Our account manager went to the factory at every key stage and sent photos and videos the same day, so the client could track progress without being on-site.

Precise Change Handling
"If the faucet channel changes to 5.5", the angle shifts and the back position changes — can you calculate that?"

When the client requested a larger channel, we calculated the geometry immediately: angle stays 9°, edge distance shifts from 195mm to 170mm. Exact numbers, no guesswork.

Product Specifications

Solid Sicilian Grey marble pedestal sinks with integrated basins, several per block

Each pedestal sink was carved monolithically (in one piece, no joins) from Sicilian Grey marble; several sinks came from a single block, and the full run of 41 required several blocks. The inner basin and deck surface received a honed/polished finish, while the exterior retained the natural rock-face texture — a signature aesthetic of the project. Units were pre-drilled for faucet and drain, and featured recessed channels for Z-cleat hardware as well as internal cutouts to reduce shipping weight without compromising structural integrity.

Why Apexstone

Why Apexstone was the right factory for Waller Creek

Carving an integrated basin from one marble block at hotel volume is a different job than fixing a basin under a countertop. The points below show how this project was controlled — and the strengths behind every custom marble pedestal sink order.

On this project

Integrated basins carved into each block

Each of the 41 units was fabricated from one Sicilian Grey block, with the basin carved directly into the stone. The surface is uninterrupted — no seam, no glued joint, no leakage risk — and the grey veining flows continuously from deck into basin.

Made the detail manufacturable without changing the look

The interior profile was shaped for fabrication — eased corners and a slightly flatter bottom — so water drains cleanly and the basin comes out of a single block, while the outer dimensions, finished appearance and every other specification stayed per the design.

A physical mock-up approved before the run

Before fabricating the order, the profile was proven on a full-size piece and approved against the real stone, not a render, before the 41 units were run.

On-site account manager at every critical stage

Our account manager went to the factory at each critical stage, checking dimensions and details against the approved drawings and sending photos and videos straight to the client — every approval directly protected the ready date.

Weight reduced without losing structural integrity

Internal cutouts lightened the monolithic units for shipping while recessed channels accommodated the Z-cleat hardware — engineered for safe transport and a correct wall installation on site.

What we bring as a manufacturer
Marble bathroom pedestal sinks

Integrated basin fabrication as a core capability

Single-block vanities — carved basins with continuous veining and no joints to fail — are a signature fabrication, run with mock-up approval and hand-verified drainage rather than assembled parts.

Custom hotel & residential stonework

Shop-drawing review and first-piece gating

We resolve manufacturability on the drawing, prove the profile on a physical sample, and only then run the order — how custom pedestal sink programs reach site matching the approved piece.

Production Workflow

Five stages, verified on site at every critical point

Hole positions had to be confirmed before any block was cut. Our account manager was on-site at each critical stage, checking dimensions against the approved drawings and sending photos and videos directly to the client — every approval directly impacted the ready date.

Technical Drawings

Shop Drawing — IF-357

The full technical drawing set was provided by the design firm and reviewed line-by-line before fabrication. Dimensions, hole positions, clear routing, and weight-reduction zones were all confirmed through multiple rounds of markups before the first block was cut.

Project Timeline

Ten weeks of close collaboration, from drawings to shipment.

June 3, 2024
Drawings Received

The design firm sends the initial shop drawings for both pedestal sink models. We review every dimension — faucet angles, Z-cleat routing, drain positions, and weight-reduction zones — and flag the details that need confirmation before any block is cut.

June 4–18
Technical Alignment & Block Sourcing

Over two weeks of back-and-forth, hole positions, clear dimensions, leg cutout tolerances, and faucet specs are locked in. Our account manager marks up photos with precise questions so there is zero ambiguity on the shop floor. Sicilian Grey marble blocks are sourced and inspected.

June 25
Production Endway — On-Site Verification

Our account manager goes to the factory to verify template placement against the approved drawings, then sends the client six photos and a video of rough-cut blocks and early shaping. A mid-production revision — enlarging the faucet channel from 4.5" to 5.5" — is calculated and confirmed the same week.

July – August 12
Mass Production & Waterproofing

All 41 units are CNC-shaped, hand-finished, drilled, and waterproofed. The client sends tester bases and hardware so every unit can be checked for fit and level before packing.

August 30
Inspection & Packing

Final QC pass. Each unit is foam-wrapped and packed in an individual wooden crate (9 packing photos + video shared with the client).
