Standard Drain Sizes: Everything You Need to Know About Floor Drains

There are many types of floor drains available on the market, each with different sizes. So what are the dimensions of floor drains?

Dimensions of Floor Drains

1. Odor-proof Floor Drains

The dimensions of square floor drains generally range from 9×9cm to 15×15cm, with diameters usually at 10cm or 13.3cm. Modified sizes may be 10×10cm or 12×12cm. Rectangular floor drains have a length ranging from 20cm to 120cm and a width of around 8cm, suitable for pipe diameters of 4, 5, or 7cm. The diameter of round floor drains typically measures between 9cm and 15cm, suitable for pipe diameters of 4, 5, or 7.5cm. The larger the size, the greater the drainage capacity, so buyers should choose based on the water flow requirements.

2. Deep Water Seal Floor Drains

For this type, the square panel measures 10cm×10cm, with a depth of 12cm to 14cm, and a pipe diameter of 50cm, with an internal diameter of 5cm. Slightly smaller pipes can be used, provided the internal diameter is not less than 4.5cm. Rectangular floor drains have a length of 20cm to 60cm and a width of 8cm, with a depth of 11cm suitable for 50cm and 75cm pipes. The circular floor drain measures 10cm×10cm, with a depth of 12cm.

3. Magnetic Automatic Odor-proof Floor Drains

The dimensions for these drains are generally 10cm×10cm, with a depth from the tiles to the elbow of the drainpipe measuring 8cm. They are compatible with 50cm pipes, having an internal diameter of 5cm, and slightly smaller pipes can also be used, but the internal diameter must not be less than 4.5cm.

4. Ultra-thin Floor Drains

These floor drains typically measure 10cm×10cm, with a panel thickness of 1.5cm, a drain body length of 2.5cm, and an overall depth of 4cm. They are suitable for 40cm pipes with an internal diameter of 4cm. This type is commonly used in older houses since they typically use 40cm pipes, while new houses generally use 50cm pipes. If the piping in a new home has been modified to 40cm or if the depth is between 4cm to 7cm, this type of drain can be used. Although its odor-proofing effectiveness is average, it offers good drainage performance.
