Understanding the Importance of Gauge in Copper Bathtubs

When investing in a copper bathtub, one of the key factors to consider is the gauge of the copper. This measurement can significantly influence the bathtub's quality, durability, and overall performance. In this blog, we’ll explore what copper gauge means, why it matters, and how to choose the right gauge for your copper bathtub.

What is Copper Gauge?

Copper gauge refers to the thickness of the copper sheet used to construct the bathtub. It is measured in inverse relation to its number; the lower the gauge, the thicker the copper. For example, a 14-gauge copper sheet is thicker and more substantial than a 16-gauge sheet.

Why Gauge Matters in Copper Bathtubs

  1. Durability: The thickness of the copper directly affects the bathtub's durability. Thicker copper (lower gauge) is more robust and less likely to dent or bend, ensuring your bathtub retains its elegant appearance for many years.

  2. Heat Retention: Copper is renowned for its heat retention capabilities. Thicker copper bathtubs (lower gauge) maintain heat longer, providing a more luxurious and enjoyable bathing experience, especially for those who love prolonged soaks.

  3. Weight and Installation: The thickness of the copper also impacts the bathtub's weight. A thicker copper tub will be heavier, which might require additional structural support during installation. This can affect installation costs and complexity.

  4. Cost: Generally, the thicker the copper (lower gauge), the higher the cost. This is due to the greater amount of material and the increased craftsmanship required. However, the investment often pays off in terms of enhanced durability and longevity.

Common Gauges for Copper Bathtubs

Copper bathtubs typically come in gauges ranging from 14 to 20. Here’s a breakdown of what to expect from each:

  • 14 Gauge (0.0641 inches): One of the thickest gauges available, 14-gauge copper offers exceptional durability, superior heat retention, and a premium feel. Bathtubs made from 14-gauge copper are less likely to dent or bend, maintaining their appearance for many years.

  • 16 Gauge (0.0508 inches): A popular choice, 16-gauge copper strikes a good balance between durability and affordability. It provides excellent heat retention and durability while being slightly lighter and more cost-effective than 14-gauge.

  • 18 Gauge (0.0403 inches): Lighter and more affordable, 18-gauge copper bathtubs still offer good durability and heat retention but may be more susceptible to dents and wear over time compared to thicker gauges.

  • 20 Gauge (0.0319 inches): The thinnest gauge typically used for copper bathtubs, 20-gauge is more affordable but less durable. These bathtubs may not retain heat as well and are more prone to damage, making them less ideal for frequent use.

Choosing the Right Gauge for Your Copper Bathtub

To determine the best gauge for your copper bathtub, consider these factors:

  • Usage: If you plan to use the bathtub frequently, opt for a lower gauge (thicker copper) to ensure better durability and heat retention.

  • Budget: Balance your budget with the benefits of thicker copper. While lower gauge bathtubs are pricier, their longevity and durability often make them a better investment in the long run.

  • Aesthetic Preferences: Thicker copper bathtubs tend to have a more substantial and luxurious appearance. Consider the visual impact you want your bathtub to have in your bathroom.

  • Installation: Think about the weight and installation requirements of thicker copper bathtubs. Ensure your bathroom structure can support the additional weight and plan for any extra installation costs.


Understanding the gauge of copper is essential when choosing a copper bathtub. It affects the tub’s durability, heat retention, weight, and cost. By considering these factors and your specific needs, you can select the ideal copper bathtub for your home. Whether you opt for a sturdy 14-gauge tub or a more budget-friendly 20-gauge option, a well-chosen copper bathtub will be a beautiful and functional addition to your bathroom for years to come.
