If you are shopping for a pedestal sink and keep seeing the term "solid surface" or "artificial stone," this article explains what that actually means, how the basin is made, and what you get from it in daily use. No jargon for its own sake — just the material, the process, and the properties that matter when you live with the sink for years.
What "solid surface" means
Solid surface — often called artificial stone — is a manufactured material made by combining a mineral filler with a binder resin, then casting it into shape. In sanitary ware, the relevant Chinese industry standard is JC/T 2116-2012, which covers this class of product under the category of non-ceramic sanitary ware.
The defining trait is in the name: it is solid and uniform all the way through. There is no separate glaze layer on top of a different body. The surface you touch is the same material as the core. That single fact drives most of the practical advantages below.
This is different from ceramic, which is fired clay protected by a glass glaze. We do not make ceramic basins, and we do not describe our solid surface products as ceramic. They are a distinct, non-ceramic material.
What a pedestal basin is
A pedestal basin is a sink where the bowl sits on a column (the pedestal) that reaches the floor. The column hides the drain and supply lines and gives the fixture a freestanding, classic look.
There are two common forms:
- Full pedestal: the column runs from floor to basin. It is the traditional look, but the column occupies the space beneath the bowl.
- Half-pedestal (semi-pedestal): a shorter shroud at the wall that leaves the floor area open.
A full pedestal trades under-sink storage for a clean, compact footprint. If you need enclosed storage, a vanity is the better choice; a pedestal gives you floor space and easy cleaning instead.
How a solid surface pedestal basin is made
The manufacturing method is casting, not firing. The general process:
- Mix. Mineral filler is blended with unsaturated polyester resin (our raw material is unsaturated polyester resin 201B) to a precise formulation.
- Cast. The mix is poured into a basin mold and allowed to cure into a single, seamless solid piece.
- Demold and finish. The cured piece is removed, trimmed, and surface-finished to a uniform gloss.
- Inspect and crate. Each unit is checked before packing.
Our production model, stated honestly
We do not own the casting line in the sense of operating our own factory building. We work with partner production that reserves dedicated casting capacity for our orders. The part of the process we control directly is quality: our own QC team is on site and inspects every unit before crating.
We say this plainly because it is also the basis of our quality claim. Buyers are welcome to verify by factory visit in person or by live video before ordering. Seeing the inspection is more useful than taking a slogan at face value.
Properties that matter in daily use
- Non-porous and seamless. With no glaze layer to craze or crack, there is no microscopic path for soil or moisture into the body.
- Repairable. Scratches and light surface damage can be sanded and re-polished in place, returning to a uniform finish. Ceramic damage of the same kind is usually permanent.
- Uniform appearance. Because the material is the same throughout, edge chips do not expose a different-colored body.
- Warm, quiet feel. Solid surface is less cold and less echoing than ceramic or metal — a small but noticeable difference in a bathroom.
- Easy to clean. A smooth, seamless surface wipes down without seams or grout lines to trap grime.
Typical specifications
Our standard pedestal basin specification:
| Spec | Value |
|---|---|
| Overall dimensions | W45 × D45 × H85 cm |
| Finish | White, gloss |
| Basin interior depth | 12 cm or 17 cm (two profiles) |
| Drain hole | 45 mm standard |
| Material | Solid surface (artificial stone), non-ceramic per JC/T 2116-2012 |
The 12 cm and 17 cm basin depths are not interchangeable — the deeper 17 cm profile holds more and splashes less; the 12 cm profile is shallower and lighter. Choose per the room.
Tested data you can verify
We publish only what was actually measured, under a named standard.
-
Independently tested to JC/T 2116-2012 (Foshan quality inspection, report G21-WT11798T):
- Water absorption: 0.1% (standard limit ≤0.5%) — the strongest result and our main selling point.
- Barcol hardness: 46 (standard minimum ≥35).
- Raw material compliance: the resin raw material — unsaturated polyester resin 201B — is compliant with EU RoHS per SGS report SZXEC23002470101. This report covers the raw material, not the finished basin, so we state it precisely as raw-material compliance.
We do not quote a stain-resistance number in our marketing. The relevant standard value is a pass-line result, not a differentiator, so we leave it out rather than imply more than the test shows.
Certification status
We do not currently hold cUPC or CE certification. Both are in progress, with test reports available on request. We will not present a certificate number we have not earned, and we encourage buyers to verify any supplier's claims independently.
Where a solid surface pedestal fits
- Homes wanting a seamless, repairable basin with a clean look and no cabinet.
- Small businesses — boutique offices, short-term rentals, cafes — where a durable, easy-clean fixture matters.
- Renovations where floor space is tight and a freestanding silhouette suits the room.
If your project requires an accessible (ADA) bathroom, note that a full pedestal does not qualify — the column blocks the required knee clearance. For those rooms, a wall-hung basin or a half-pedestal that preserves clearance is the correct choice.
Care and minor repair
Daily care is simple: a soft cloth with mild detergent. Avoid abrasive cleaners that would dull the gloss over time.
For a light scratch, the surface can be renewed with fine abrasive and polish — a real advantage over ceramic, where the same scratch is permanent. For deeper damage, a professional refinisher can restore the area. This repairability is why solid surface performs well over a long service life.
Frequently asked questions
Is solid surface the same as ceramic? No. Solid surface (artificial stone) is a mineral-and-resin composite cast into shape; ceramic is fired clay with a glaze. They are different materials, and we sell only the solid surface type.
Is it porous? No. It is non-porous and seamless, with no glaze to craze. Our units tested at 0.1% water absorption under JC/T 2116-2012.
Can scratches be fixed? Yes. Light surface damage can be sanded and re-polished in place, unlike ceramic, which chips permanently.
Do you have cUPC or CE? Not yet. Both are in progress, with test reports available. We do not claim certifications we have not earned.
Who makes it — are you a factory? We reserve dedicated casting capacity with partner production and run our own QC team on site inspecting every unit before crating. Factory visits are welcome in person or by live video.
Before you buy: seeing the material
Because solid surface is a uniform material, photos understate the feel — the warmth, the lack of glaze sheen, and the weight. If you are specifying more than one or two units, request a physical sample or a live video look at the finish and edge before committing. It is a low-cost step that removes the main risk in buying a material you cannot physically compare in a showroom.

About the data: tested values are drawn from report G21-WT11798T (JC/T 2116-2012) and SGS report SZXEC23002470101 for the resin raw material. Certifications are stated as currently in progress. Confirm dimensions and compliance against your own requirements before purchase.
