The Ultimate Guide to Floor Drain Pipe Dimensions

Installing a floor drain in bathrooms and kitchens is essential primarily for drainage and odor prevention. What size should the drainage pipe beneath the floor drain be? Also, what are the material classifications?

Everything You Should Know About Floor Drain Pipe Sizes

1. The size of the floor drain drainage pipe primarily comes in two specifications: one is DN110, which measures 110 millimeters in diameter, and the other is DN50, with a diameter of 50 millimeters. Generally, for floor drain drainage pipes, the latter (DN50) is the commonly used size, making 50 millimeters the suitable diameter.

2. If using PVC drainage pipes, both 50 millimeters and 110 millimeters can be utilized. For main drainage pipes, two different specifications can be adopted, which are typically 90 millimeters and 110 millimeters.

3. Before installing a floor drain, it is crucial to determine the size of the drainage pipe. If you choose a 50×50 configuration, the drainage pipe size should match at 50 millimeters to ensure proper installation and effective drainage and leak prevention.

Types of Floor Drains

1. Floor drains might seem insignificant during renovation, but they are a necessary component of the overall drainage system. Installing a floor drain helps prevent foul odors from returning and inhibits the spread of bacteria and viruses.

2. One type is the T-shaped floor drain, which features a trapezoidal structure that can control drainage. It can be closed when not in use and opened during drainage, offering a longer lifespan and a more affordable price.

3. The water-sealed floor drain operates based on water to open and close effectively. It is best to choose materials like stainless steel or copper; if alloy types are selected, they might rust easily.

4. There are also silicone floor drains made primarily of silicone material that do not have issues with returning odors, and silicone drain cores are generally priced affordably.

5. Additionally, there are flap-style floor drains that automatically open and close based on the water's gravity. They are user-friendly, although their odor prevention might not be as effective.

In summary:The above content specifically discusses the typical sizes of drainage pipes for floor drains, which can be either 50 millimeters or 110 millimeters. Additionally, there are various types of floor drains, and selecting a suitable one for bathrooms or kitchens can effectively achieve odor prevention and leakage protection.
