The best copper range hood makers fall into three construction camps: hand-hammered shops that raise and planish sheet copper by hand, spun shops that form round or conical shapes on a lathe, and cast shops that pour molten metal into a mold. Each method produces a different surface, wall thickness, and price. For most kitchens, a hand-hammered hood in 16- to 18-ounce (roughly 20- to 22-gauge) copper with a properly engineered stainless or aluminum liner gives the best balance of beauty and performance. Whichever you choose, ask every fabricator how the hood is joined, what is inside it, and who engineers the ventilation.
This guide compares the three methods, explains gauge and finish, covers liners and ventilation, and closes with a vetting list you can take to any shop.
Quick Comparison: Hand-Hammered, Spun, and Cast
| Hand-hammered | Spun | Cast | |
|---|---|---|---|
| How it's made | Sheet copper formed and struck by hand | Disc forced over a form on a lathe | Molten metal poured into a mold |
| Best for | Traditional, rustic, and French country kitchens | Round, conical, or dome shapes | Sculptural, ornate, or architectural detail |
| Surface | Visible hammer facets that catch light | Smooth, with fine concentric tooling lines | Dense, with detail built into the form |
| Typical wall | 16–20 oz sheet | Often thinner | Thicker, sculpted sections |
| Customization | High | Limited to rotational forms | High, but tied to the pattern |
| Relative cost | Moderate to high | Low to moderate | Highest |
Hand-Hammered Copper Hoods
A hand-hammered copper hood starts as flat sheet. The artisan forms the panels, then strikes the surface with planishing hammers to create the faceted texture. The hammering does more than decorate: it work-hardens the metal and helps the panels hold their shape across large flat areas.
What to look for
- Consistent, intentional texture. Hammer marks should read as a rhythm, not as random dents. Ask to see a full-size sample, not only photos.
- Seam quality. Well-made hoods use mechanical seams, folded and locked joints, or fully welded and dressed seams. Seams should be nearly invisible or clearly designed as a feature.
- Reinforcement. Large copper panels can oil-can (flex and ripple) without internal framing. Ask what supports the structure behind the sheet.
- Rivets and straps. Decorative bands and rivets should be functional or well executed. Applied-on hardware that is only glued or tacked is a warning sign.
Hand-hammered work suits farmhouse, French country, Tuscan, and transitional kitchens, and it is where most custom copper hood makers concentrate their catalog.
Spun Copper Hoods
Spinning forms a copper disc over a mandrel as it rotates on a lathe. It is efficient and well suited to round or conical shapes, so you will see it in cone-style island hoods, domes, and pendant-style canopies.
Strengths and limits
- Strengths: clean symmetry, a smooth finish, and often a lower price than fully handworked alternatives.
- Limits: shapes must be rotationally symmetrical. A rectangular or tapered chimney cannot be spun in one piece, so those parts are usually fabricated separately and joined.
- Questions to ask: Is the entire hood spun, or only the canopy? How are spun and flat components joined? What gauge is the spun section after stretching? Spinning thins metal at the stress points, so the finished wall can be thinner than the starting sheet.
Cast Metal Hoods
Casting is a different discipline entirely. Rather than shaping sheet, the foundry pours molten metal into a mold, which allows carved detail, deep relief, integrated corbels, and sculptural forms that sheet cannot produce. Cast work is dense and substantial.
True cast copper hoods are uncommon because copper is demanding to pour and finish. Most cast range hoods are made in zinc, brass, bronze, or pewter, which cast beautifully and hold fine detail. If you love the character of cast work but want a warm copper tone, a cast brass or bronze hood is often the practical answer. At La Bastille we handcraft cast hoods in zinc, brass, bronze, pewter, and copper, and our designers will tell you candidly which metal suits the detail you have in mind.
Ask any cast-hood shop where the casting happens. Some companies import castings and assemble them domestically, which is a different proposition from a shop that sources, designs, and fabricates in one place.
Gauge and Thickness: What the Numbers Mean
Copper is sold by weight per square foot (ounces) and by gauge. Heavier means thicker.
| Weight | Approx. gauge | Approx. thickness | Typical use |
|---|---|---|---|
| 12 oz | 26 | 0.0162" | Roofing, flashing; too thin for most hoods |
| 16 oz | 24 | 0.0216" | Common in budget hoods |
| 20 oz | 22 | 0.027" | Good all-around hood gauge |
| 24 oz | 20 | 0.0324" | Heavier, flatter panels, less flex |
Gauge numbers for copper vary by reference chart, so ask for the thickness in ounces or inches in writing. Thicker metal resists denting and oil-canning, but it is harder to hammer and form, so a fabricator may use different weights for the canopy, straps, and trim.
A reasonable rule: choose at least 20 oz for large flat surfaces and verify that the quoted gauge matches the finished product, not just the raw coil.
Finishes: Living, Sealed, and Pre-Aged
Copper is a living metal. Left alone, it darkens from salmon-pink to brown over months and may eventually develop green verdigris in humid or coastal conditions. Your finish choice determines how much of that you control.
- Natural (unsealed): The surface evolves with use. Fingerprints, steam, and cooking vapors leave a story. This is the most authentic option and requires only occasional polishing if you want to restore brightness.
- Hand-applied patina: The fabricator chemically ages the copper to a chosen depth, from light amber to deep chocolate, before it ships. The result is more consistent from day one.
- Polished or bright: A mirror or satin shine, which will tarnish unless maintained.
- Sealed or lacquered: A clear coating slows oxidation. It can peel, yellow, or wear unevenly near the cooktop, and it is difficult to repair invisibly. Ask what coating is used and how it is reapplied.
Be wary of anything described as "metallic paint" or a plated effect. A hood made from solid copper should be solid copper through the thickness of the sheet, not a coating over steel or aluminum.
Ask for finished samples in the actual finish you are buying, ideally large enough to compare against your cabinetry and stone.
Liners and Ventilation: The Part Most Buyers Skip
A copper hood is usually the shell. What pulls smoke, grease, and heat out of your kitchen is the insert or liner inside it, and this is where cheap and well-built hoods diverge most.
Liner options
- Integrated liner (premium): The fabricator supplies a purpose-built liner sized to the hood, with baffle or mesh filters and lighting. This is the cleanest integration and the simplest for the installer.
- Third-party insert: The hood is built around a standard insert from an established ventilation brand. This offers wide choice of blower and performance specs, but fit tolerances must be exact.
- Shell only: You or your contractor supply the ventilation. This works for experienced builders but puts coordination risk on you.
La Bastille builds custom hoods fully equipped with a premium liner for seamless integration, so the fit is engineered at the shop rather than improvised on site.
Ventilation numbers to confirm
- CFM rating: Match airflow to your cooktop. A common rule of thumb is about 100 CFM per 10,000 BTU of total burner output, though the right number depends on your range and local code.
- Duct size and run: Smaller or longer ducts reduce real-world performance. Confirm the diameter and the maximum run the blower is rated for.
- Blower placement: In-line and remote blowers reduce kitchen noise compared with internal ones.
- Makeup air: High-output ranges often trigger makeup air requirements under local code. Your contractor or mechanical engineer should confirm this.
- Filter type: Baffle filters are easy to clean and dishwasher-safe in many cases. Mesh filters need more frequent replacement.
- Lighting: Ask about LED fixtures, color temperature, and dimmability.
A beautiful hood that cannot move air is a very expensive sculpture. Ask for the performance data of the specific liner in your hood.

Frequently Asked Questions
What gauge copper is best for a range hood?
Twenty-ounce copper (about 22 gauge) is a sound choice for most hoods. Use 24 oz for large, flat panels where you want maximum resistance to flexing. Sixteen-ounce copper is acceptable for small or heavily textured pieces but dents more readily.
Is a hand-hammered copper hood worth the extra cost?
If you want visible texture and a hand-wrought character, yes. Hammering adds labor and strength to the sheet and hides everyday fingerprints better than a smooth surface. If your design is a clean, modern cone, a spun hood may suit you better.
Will a copper hood turn green?
Not usually in an interior kitchen. Copper typically darkens to brown. Green verdigris appears mainly with prolonged moisture and exposure to salts or acids. Regular cleaning and a controlled patina keep the color predictable.
Should I seal my copper hood?
Sealing slows color change but can wear unevenly and is difficult to repair. Many owners prefer a natural or hand-patinated finish that ages gracefully and can be refreshed with gentle polishing.
Can copper hoods be cast?
Yes, but cast copper is less common than cast zinc, brass, or bronze. If you want sculptural relief, we can advise which cast metal best delivers the detail and color you are after.
How long does a custom copper hood take to make?
Plan on several months. At La Bastille, lead times are typically 12–14 weeks after drawings are approved, plus time for design and sampling.
What size hood do I need?
As a general guide, the hood should be at least as wide as the cooktop, and 3 inches wider on each side is better for capture. Check your range manufacturer's mounting height and local code.
Next Steps
When you compare shops, look past the photographs. Ask about thickness, joinery, finish, and the liner, and ask to see samples. A fabricator who welcomes these questions is likely to build a hood that performs as well as it looks.
