What does kiln-carved mean on a glass bar top?

Kiln-carving is a process in which glass is fired in a kiln over a textured bed — in this case, a hand-worked sand surface — so the heat softens the glass and allows it to take on the precise contours of the texture beneath it. The result is a surface that is permanently part of the glass, not applied to it. The texture lives on the underside, meaning the top surface stays smooth and cleanable while the visual depth lives below, amplified by the LED light source behind it.

How is a glass bar top supported without drilling through the glass?

Three cantilevered steel brackets, anchored into the bar structure below, carry the full load of the glass surface. The glass rests on the bracket faces and is bonded with ultra-clear silicone — no hardware passes through the glass at any point. This eliminates stress concentration points, aesthetic intrusion, and future maintenance issues caused by through-drilling.

How does the LED lighting system work inside a kiln-carved glass bar top?

The Ambiance Machine™ RGB LED system mounts along the interior edge of the bar structure and fires light upward through the glass. The carved texture catches and scatters that light, creating a surface that appears to glow from within. The system operates across 8 million color combinations at 0–100% intensity, with programmable scenes and optional photocell trigger that activates the bar automatically at dusk.

What are the maintenance requirements for a kiln-carved glass bar top?

The surface requires no special treatment. The top surface is smooth polished glass — cleaning is the same as any glass surface, a damp cloth or standard glass cleaner. No sealing, no waxing, no periodic treatment required. Low-iron glass is non-porous, does not stain, and does not react with alcohol, citrus, or cleaning products.

How was the wave texture pattern developed for the Mantoloking glass bar top?

The texture was designed interactively — client and craftsman working from the bar's geometry and the room's flow to arrive at a pattern that felt native to the space. Once the bar base drawings were confirmed, multiple textural iterations were developed. The client selected the wave pattern, which was then scaled and anchor-pointed so the hand-worked sand bed in the kiln matched it as faithfully as the process allows.

Custom glass sink with integrated LED lighting by Downing Designs Tampa Florida

Glass Sinks
Sculptural. Floating. Lit.

Begin a Commission

Not a fixture.
A feature
in glass.

Custom glass sinks that float — wall-mounted, non-porous, and integrated with LED lighting that transforms an ordinary bath into something worth photographing. Available as single basin, double sink, or long trough configurations for residential and commercial installations.

Every sink is fabricated by Jeff Downing in Tampa using architectural-grade kiln-formed glass at 1½″ thickness. Non-porous by nature — no sealing, no maintenance cycle, no compromise. Delivered and installed personally, anywhere in the country.

Why Glass Sinks by Downing Designs

Floating Wall Mount

Wall-mounted installation with no visible support structure. The sink appears to float — increasing the sense of space in the bath and eliminating the visual weight of a traditional vanity cabinet.

Integrated LED Lighting

Edge and under-surface LED systems engineered into the sink from the start. At night, with the lights at 30%, the basin glows from within — an effect no ceramic or stone fixture can produce.

Zero Maintenance

Non-porous kiln-formed glass requires no sealing, no special cleaners, no grout. Soap, water, and daily use wipe clean without staining, etching, or degrading the surface over time.

Single, Double, or Trough

Available in single basin, double sink, and long trough configurations. Custom dimensions cast to your exact specifications — width, depth, drain placement, and edge profile all specified per project.

Architectural Thickness

Fabricated at 1½″ architectural thickness — the same specification used in commercial hospitality environments. Structural, durable, and visually substantial without the weight of stone.

Personal Installation

Jeff Downing delivers and installs every piece himself. No third-party crews, no handoff. The sink arrives exactly as specified and is set by the person who built it, anywhere in the country.
