Glass Countertops
Kiln-Formed in Tampa.
Begin a Commission
Not a surface.
A statement
in glass.
Kiln-formed glass countertops for kitchens, bathrooms, wet bars, and islands — hand-textured, non-porous, and built to last without a maintenance schedule. Each piece is fabricated by Jeff Downing in Tampa and installed personally, anywhere in the country.
Glass is the only countertop material that is simultaneously non-porous, heat-resistant, optically transparent, and capable of integrated LED illumination. There is no grout, no sealing cycle, no staining. The surface you commission is the surface you live with for decades.
Zero Maintenance
Non-porous kiln-formed glass requires no sealing, no special cleaners, no renewal cycle. Acids, oils, and wine wipe clean. The surface performs the same on day one as it does in year twenty.
Hand-Carved Texture
Every surface is carved by hand in the Tampa studio and kiln-fired until the texture is permanent. No two pieces are identical — the texture is part of the material, not applied to it.
Integrated LED Option
Edge and under-surface lighting systems engineered into the countertop from the start. The kitchen island becomes something different after dark — not a surface, but a source of light.
Ultra-Low-Iron Glass
Standard glass reads green under LED light. Ultra-low-iron glass is optically clear — the full spectrum of light comes through without distortion, whether the top is lit or unlit.
Single-Piece Capability
Kiln dimensions allow single-piece fabrication up to 130 inches. No seam across a kitchen island. No grout line through a bathroom vanity. One piece, one surface, no compromise.
Personal Installation
Jeff Downing delivers and installs every piece himself. No third-party crews, no handoff, no risk. The countertop arrives exactly as specified and is set by the person who built it.
How long does a custom glass countertop take?
Most custom glass countertops take six to eight weeks from design approval to installation. That window covers hand-carving the texture, kiln-firing, waterjet cutting, edge polishing, and personal delivery and installation by Jeff Downing.
How large can a single glass countertop be?
Downing Designs fabricates single-piece kiln-formed glass up to 130 inches long, so most kitchen islands, vanities and wet bars are built as one continuous surface with no seam.
How thick are Downing Designs glass countertops?
Standard thicknesses are ¾ inch, 1 inch and 1½ inch, in ultra-low-iron glass. Custom thicknesses are available, and thickness is specified per project based on span, support and lighting.
Do glass countertops need to be sealed?
No. Kiln-formed glass is non-porous, so it never needs sealing, special cleaners or a renewal cycle. Wine, oils and acids wipe clean, and the surface performs the same in year twenty as on day one.
Where does Downing Designs install glass countertops?
Every countertop is fabricated in Tampa, Florida and installed nationwide, with select international projects. Jeff Downing delivers and installs each piece personally — no third-party crews.
