I. Introduction
The Europeans and Americans have different linear shower drain sizes, making it difficult for exporters and manufacturers to meet both areas’ needs. Distributors, exporters, and professional installers especially should learn the difference between drain sizes and fail to do so at their own risk. This guide also provides an analysis of the most common linear shower drain sizes and tips for International Business.
II. What Is the Most Common Linear Shower Drain Size?
However, to look at the differences between Europe and the US let’s answer the simplest question first: What is the average size of a drain pipe?
- The most commonly used linear shower drain size for a conventional shower stall in the USA is 2 inches to correspond to the UPC code.
- In Europe, 40mm (1.57”) or 50 mm (1.96”) thickness is most commonly used, depending on the specifics of the legislation in the country.
- Despite these small discrepancies, it can lead to large issues if one is exporting drain systems or installing products in different countries.
Fact: It has been estimated that more than a third of plumbing installation problems in structures abroad are as a result of size disparities and incompatibilities. Determining the linear shower drain size is very important in order to enhance its installation.
III. European vs US Linear Shower Drain Size Standards
To help you better understand the differences, here’s a breakdown of linear shower drain size standards in Europe and the US:
| Feature | Europe | United States |
| Standard Drain Pipe Size | 40 mm (1.57 inches) or 50 mm (1.96 inches) | 2 inches (50.8 mm) |
| Linear Drain Lengths | 600 mm – 1200 mm (23.6 – 47.2 inches) | 24 inches – 60 inches |
| Common Material | Stainless steel, ABS plastic, PVC | Stainless steel, PVC, ABS plastic |
| Flow Rate Capacity | 24-36 liters per minute | 30-45 liters per minute |
| Slope Requirements | 1% – 2% | 1/4 inch per foot |
| Certification Standards | EN 1253 (European plumbing standard) | UPC, ASME A112.18.2/CSA B125.2 |
IV. Key Differences Explained
Pipe Diameter Variations: EU uses a 40-50mm pipe for drains while the US uses a slightly larger 2 inch pipe. Such a difference can lead to problems in fitting since most of the products are international ones.
- Drain Lengths of Lines: Regarding length, the American market favours long linear drains, up to 60 inches while in Europe, it is a preference for 600mm-1200mm lengths.
- Flow Rate: This is the amount of flow per minute and depending with the size of the pipe, the range of the flow rate varies in Europe to between 24 to 36 L/min and in US slightly higher.
- Slope Differences: According to the US plumbing code, the standard is 1/4 inch per every foot, while European plumbing needs to have a slope of 1-2 per cent for efficient water flow.
- Certification Standards: Products intended for the European markets should have EN 1253, US drains should have UPC or ASME standards.
Fact: More than half of shower drain systems imported actually need further adjustments to meet the plumbing needs in the country.
V. Tips for Exporters and Installers
As an exporter, manufacturer or plumber dealing with Europe and the US the following ideas will help enhance the compatibility of products.
- Confirm Laws of the Specific Country or State – Laws are different in different countries and states within the USA. It’s important to double check before exporting or installing the goods.
- Provide Versatile Products – It is possible to obtain drains that fit both 40 mm and 50 mm pipes in various manufacturers’ ranges.
- Create Size Conversion Chart – Present tables displayed to the contractors and buyers to enable them select proper drain size.
- Universal Adapters – Sellers should consider developing pipe adapters that can connect between European and American sizes.
All those that involve an international sale should ensure that they let their clients know about the variations in drain sizes that may cause some inconveniences.
VI. Conclusion
Those manufacturers and exporters of international business should be acquainted with the standard linear shower drain size between Europe and the US, negotiate for more flexible solutions, and obtain the required certifications to overcome these hurdles.
