One craftsman.
Every stage.
No substitutes.
Jeff Downing has personally designed, fabricated, delivered, and installed every piece since 2000. There is no factory, no production team, no outsourced fabrication. Kiln dimensions reach 130 inches — large enough to produce single pieces that European suppliers cannot air-freight. That is the difference between a seam and no seam.
Downing Designs holds an Aurora Award for Best Kitchen, a 5-star Houzz rating, and a feature in DuPont Registry Home & Design. Jeff Downing holds a BS in Chemistry from the University of Pittsburgh — the science behind every firing.

How does a commission work?
- The call. Describe the room, the mood, and how it's used after dark. You speak with Jeff Downing directly, before any money changes hands.
- The design. Size, texture, edge, thickness, and lighting are set around the space, not pulled from a catalog.
- The firing. Each piece is kiln-formed and hand-textured in the Tampa studio. Textures are studio-made, never stamped patterns.
- The install. The studio delivers and installs nationwide, with the lighting tuned to complement the room's decor.
Before You Call
What is a kiln-formed glass bar top?
A kiln-formed glass bar top is a single piece of glass heated and fused in a kiln to create texture, depth, and seamless spans up to 130 inches — as opposed to cast resin, laminated panels, or seamed sections. Every piece is fabricated by hand in Tampa, FL, with no outsourced production.
How large a single piece can Downing Designs pour?
Single continuous glass pieces up to 130 inches are produced in-house on Denver Glass Machinery kilns. Larger installations use engineered multi-panel layouts with Singularity™ seaming to preserve visual continuity across the full span.
How much does a glass high bar cost?
Most glass high bars installed in Florida come in under $10,000 all in, including glass, brackets, LED lighting, delivery, and installation. A 63-inch bar top is under $6,500 installed; a 126-inch bar top is under $12,500 installed.
How long does a commission take?
Lead time scales with complexity. Twelve 36" × 10" × 1.5" glass stair treads typically ship in about 8 weeks. In-stock glass high bars can be installed in 2 weeks or less, including delivery, drilling the lower countertop, and LED installation.
How is a glass high bar installed?
A glass high bar sits 42 inches above the floor, over a 36-inch lower counter, on just two 4.5-inch cantilever brackets — even on bars up to 130 inches long. The glass reads as floating, with nothing visible underneath but light.
Does Downing Designs install outside Florida?
Yes. Downing Designs has fabricated and personally delivered custom glass bar tops, countertops, and lava stone surfaces nationwide, handling design, fabrication, delivery, and installation directly — no subcontracted install crews.
How long has Downing Designs been fabricating glass?
Founder Jeff Downing has been the sole craftsman behind Downing Designs since 2000, personally handling every piece from initial design through final installation for over 25 years.
What's the difference between a glass bar top and PyroArch™ glazed enamel?
Glass bar tops are kiln-formed from a single piece of glass. PyroArch™ is a fired-enamel surface on a white nanoglass substrate, our American-made alternative to glazed lava stone, with different heat and outdoor performance characteristics.
