Difference Between Dry Area Drains and Wet Area Drains: A Comprehensive Guide

When renovating a house, we typically install drains in both the dry and wet areas of the bathroom. What is the difference between dry area drains and wet area drains? Below, I'll briefly introduce the differences.

Difference Between Dry Area Drains and Wet Area Drains: A Comprehensive Guide

1. Different Usage Areas: Dry area drains are usually installed in places like washbasins that are less exposed to water. Wet area drains are primarily installed in shower areas where water frequently splashes.

2. Different Functions: Dry area drains often use self-sealing drains, while wet area drains typically use U-shaped water-sealed drains. Self-sealing drains have better sealing properties, sealing automatically when there is no water. Water-sealed drains have poorer sealing and cannot function without water. Self-sealing drains operate with a magnetic core, which is prone to damage. In contrast, water-sealed drains use a gravity core and have a longer lifespan.

How to Choose a Drain

1. When selecting a drain, pay attention to the material. Drains can be made from PVC, stainless steel, or cast copper, among others. It is advisable to choose stainless steel drains because PVC drains tend to age easily, and cast copper drains are more expensive. Overall, stainless steel drains offer a better cost-performance ratio. The styles of drains vary, including rectangular, square, and round options. You can choose different types based on your personal preference.

2. Consider the installation location when choosing a drain. For installation in dry areas like balconies or kitchens, a T-shaped drain may be suitable. For use in the shower area of a bathroom, a U-shaped water-sealed drain is ideal. If it’s for washing machine drainage, a dedicated washing machine drain should be selected. Additionally, ensure that the drain core and drainpipe are compatible, as mismatches can affect sealing and drainage effectiveness.
