Product PDF GL004

SANIKB GL004 is a transparent black glass vessel sink designed for above-counter bathroom vanities that need a darker glass accent without the heavy look of a fully opaque basin. The round bowl is made from 12 mm tempered glass and measures 420 × 420 × 145 mm, giving it a compact vessel profile with visible smoked-glass depth. Its tinted black transparency allows countertop color, lighting, and faucet finish to influence the final appearance. This makes GL004 a practical fit for powder rooms, boutique hospitality bathrooms, showroom displays, and modern residential vanities where the sink needs to add contrast while still keeping the reflective quality of glass.

GL004 transparent black glass vessel sink

Smoked Glass Depth for a Round Above-Counter Vanity Bowl

GL004 focuses on one clear product difference: transparent black tinted glass. The smoked finish gives the vanity a darker accent while keeping the reflective, translucent quality of glass.

Smoked Black Transparency Without a Solid-Color Look

GL004 is not a flat, fully opaque black bowl. Its main design value comes from the smoked transparent glass, which allows light to pass through the basin while still creating a darker vanity focal point. The rim appears more defined than a fully clear option, and the lower bowl area creates a deeper shaded effect.

This makes the sink useful for buyers who want a dark bathroom accent without making the vanity feel visually heavy. On lighter countertops, the transparent black tint creates stronger contrast. On darker surfaces, the basin becomes more integrated and subtle.

420 mm Round Bowl for Compact Vessel Layouts

GL004 measures 420 × 420 × 145 mm, giving it a round vessel shape with a moderate above-counter height. The 420 mm footprint works well for many single-sink vanity layouts, while the circular bowl avoids the directional alignment concerns often associated with angular basin shapes.

The round profile also helps soften the vanity composition. Instead of creating a sharp geometric block, GL004 adds a darker glass form with a smooth outline for powder rooms, model homes, boutique bathrooms, and display settings.

12 mm Tempered Glass With a Defined Dark Edge

The basin is made from tempered glass with a listed 12 mm thickness. This thickness gives the rim a substantial visual edge and helps the transparent black tint appear deeper around the bowl. The glass surface also creates reflection and shadow, which are important parts of the smoked appearance.

Because the material remains transparent, GL004 interacts with the surrounding vanity environment more than an opaque basin would. Countertop color and bathroom lighting should be reviewed before final specification.

Faucet and Drain Planning for the 145 mm Vessel Height

GL004 is designed for above-counter vessel installation, so the total finished height includes both the vanity and the 145 mm bowl height. This should be checked before the cabinet, countertop, and faucet are finalized.

Confirm vessel faucet height and spout reach before installation.

Align the drain hole with the bowl position and plumbing below the counter.

Check clearance between the bowl rim, faucet, backsplash, and mirror.

Do not assume faucet, drain, or mounting accessories are included unless confirmed separately.

How Countertop Color Changes the GL004 Appearance

Transparent black glass does not look identical on every vanity top. The same GL004 bowl can read as a high-contrast feature basin or a quieter tone-on-tone dark glass accent depending on the countertop and lighting.

On light countertops The smoked-glass layering becomes more visible, and the dark rim creates stronger contrast.

On dark countertops The basin looks more integrated, with a richer and more understated appearance.

GL004’s Position Within Dark-Tinted Glass Bowl Options

GL004 should be selected when the project needs a round smoked-glass vessel bowl rather than a fully clear, opaque, matte, or angular design. Its transparent black tint gives the vanity more shadow and contrast while still keeping the visual lightness of glass.

Compared with a fully clear option, GL004 creates a darker rim and deeper bowl appearance. Compared with an opaque dark basin, it allows more light movement through the material. Matte or diffused glass styles reduce reflection, while GL004 keeps a glossy surface. Angular bowls create sharper geometry, but GL004 uses a round outline for a softer bathroom profile.

Finish focus Transparent black tint with smoked-glass depth.

Shape focus Round bowl for a softer vanity outline.

Install focus Above-counter vessel layout with 145 mm height.

Selection focus Best for dark contrast without a fully opaque look.

FAQs

Is GL004 fully black or transparent black?

GL004 is transparent black, also described as smoked black tinted glass. It is not a fully opaque black basin. Light can pass through the glass, giving the bowl a darker but still translucent appearance.

What size is the GL004 vessel sink?

GL004 measures 420 × 420 × 145 mm. It has a round above-counter vessel shape and a listed glass thickness of 12 mm.

Is GL004 installed above the counter?

Yes. GL004 is designed for above-counter vessel installation. The bowl sits on top of the vanity surface, so faucet height, drain position, and finished vanity height should be confirmed before installation.

How does the transparent black tint affect the finished vanity look?

The tint gives GL004 a darker rim and deeper bowl appearance while still allowing light through the glass. It is suitable for buyers who want more contrast than a fully clear bowl but do not want the weight of an opaque dark basin.

What countertop colors work well with GL004?

Light countertops create stronger contrast and make the smoked-glass effect more visible. Dark countertops create a more integrated look. The best choice depends on whether the sink should stand out or blend into the vanity design.

Are the faucet and drain included with GL004?

The supplied product information does not confirm that a faucet or drain is included. Buyers should verify faucet, drain, and accessory details separately before ordering.
