When shopping for a copper bathtub, you may come across terms such as 14-gauge and 16-gauge copper. But what exactly does copper gauge mean, and does a thicker copper tub always make a better bathtub?
Both can be excellent choices for a handcrafted copper bathtub. The main differences come down to copper thickness, weight, rigidity, construction, and your specific bathtub design.
Here’s what to know before choosing between a 14-gauge and 16-gauge copper tub.
What Does Copper Gauge Mean?
Gauge refers to the thickness of the copper sheet used to construct the bathtub. One important thing to remember is that a lower gauge number means thicker copper.
So:
- 14-gauge copper is thicker and heavier
- 16-gauge copper is slightly thinner and lighter
The exact thickness can vary somewhat depending on the sheet-metal standard and manufacturing tolerances, so gauge is best used as a practical way to compare material thickness rather than as the only measure of bathtub quality.
14-Gauge vs. 16-Gauge Copper Tub at a Glance
| Feature | 14-Gauge Copper | 16-Gauge Copper |
|---|
| Copper Thickness | Thicker | Slightly thinner |
| Weight | Heavier | Lighter |
| Rigidity | Greater | Excellent for most tub designs |
| Handling | More difficult due to weight | Easier to handle |
| Best For | Customers wanting heavier construction or certain custom designs | Most standard and custom copper tubs |
| Cost | Generally higher | Generally more economical |
What Are the Benefits of a 14-Gauge Copper Bathtub?
The biggest advantage of 14-gauge copper is its heavier construction.
Because more copper is used, the bathtub will generally feel more substantial and have greater rigidity. This can be appealing for customers who specifically want an especially heavy-duty copper bathtub.
14-gauge copper may also be considered for certain large or highly customized bathtub designs, depending on the tub's shape and construction.
However, thicker does not automatically mean that 14 gauge is necessary for every bathtub.
A well-designed 16-gauge copper bathtub can already provide excellent strength and durability for normal residential use.
Is 16-Gauge Copper Good for a Bathtub?
Absolutely.
16-gauge copper is an excellent choice for a handcrafted copper bathtub and offers a good balance between strength, weight, workability, and cost.
When properly designed and handcrafted, 16-gauge copper provides the structural integrity needed for most freestanding bathtub applications without adding unnecessary weight.
This is why it is commonly used for high-quality copper tubs.
At EliteBathtub, our standard copper bathtubs are handcrafted using heavy-duty 16-gauge copper, while 14-gauge copper can be considered for custom projects upon request.
Does a Thicker Copper Tub Last Longer?
Not necessarily.
Copper itself is an exceptionally long-lasting material, so the lifespan of a copper bathtub isn't determined by gauge alone.
The overall quality of the tub also depends on factors such as:
Material quality, craftsmanship, structural design, welding and joining, finish quality, installation, and proper care.
For example, a well-constructed 16-gauge bathtub can be a better product than a poorly constructed tub made from thicker copper.
That's why it is important to consider the entire construction of the bathtub, rather than comparing gauge numbers alone.
Does Copper Gauge Affect the Weight of the Tub?
Yes.
A 14-gauge copper bathtub will generally be heavier than the same bathtub made from 16-gauge copper because more material is being used.
The final weight, however, also depends on the bathtub's dimensions, shape, base, decorative details, and construction.
If you're ordering an especially large custom copper tub, the additional weight should be considered when planning delivery and installation.
What About Single-Wall and Double-Wall Copper Tubs?
Copper gauge and wall construction are two different specifications.
A bathtub can be constructed using a single layer of copper, or certain designs may incorporate a different construction method.
A heavier gauge does not necessarily mean that a bathtub needs a double-wall construction. For example, depending on the design, a properly engineered single-wall 14-gauge copper tub can already be very substantial and stable.
The appropriate construction should be determined by the bathtub's size, shape, base or feet, and overall design—not simply by assuming that more layers are always better.
Which Is Better: 14 Gauge or 16 Gauge?
There isn't one answer that is right for every bathroom.
Choose 16-gauge copper if you want a durable, substantial copper bathtub that offers an excellent balance of strength, craftsmanship, and manageable weight. For most residential copper bathtub designs, it is an excellent choice.
Consider 14-gauge copper if you specifically prefer heavier construction or your custom bathtub design calls for additional material thickness.
For custom projects, it's best to evaluate the entire bathtub design rather than selecting the gauge independently.
Don't Forget About Copper Quality
Gauge tells you how thick the copper is—but it doesn't tell you everything about the copper itself.
When comparing copper bathtubs, also pay attention to the purity and quality of the material.
Elite Bathtub's handcrafted copper bathtubs are made from 99% pure copper and are lead-free, rather than relying on recycled copper of uncertain composition. Combined with heavy-duty construction and handcrafted fabrication, this creates a bathtub designed to provide both beauty and long-term performance.
Customize Your Copper Bathtub
One of the biggest advantages of choosing a handcrafted copper tub is the ability to create something specifically for your bathroom.
At Elite Bathtub, our copper bathtubs can be customized in:
- Size and dimensions
- 14-gauge or 16-gauge copper, depending on the design
- Smooth, light-hammered, or heavy-hammered texture
- Copper finish and patina
- Drain location
- Overflow configuration
- Shape and profile
- Decorative details
For custom orders, a CAD drawing is provided for review and approval before fabrication, allowing you to confirm the dimensions and important design details before your bathtub is handcrafted.
