Choosing the Right Toilet: 300mm vs. 400mm for a 350mm Flange Distance

When choosing a toilet, it is important to consider the distance from the wall (known as "坑距" in Chinese) in your home to determine the appropriate size to purchase. Here’s an introduction on whether to select a toilet with a 300mm or 400mm distance when the distance is 350mm.

Choosing a Toilet with a 350mm Distance: 300mm or 400mm

If the distance is 350mm, neither the 300mm nor the 400mm toilets are suitable; instead, you should choose a toilet that has a 350mm distance. Although you can technically install a 300mm toilet, it will sit a bit farther from the wall, making it more difficult to clean. On the other hand, a 400mm toilet cannot be installed at all.

How to Choose a Household Toilet

1、Toilet Glaze

When selecting a toilet, first examine the glazing on the surface. A good glaze should be smooth and even, without any roughness or texture. This enhances its self-cleaning ability and prevents yellowing over time. You can try touching the toilet surface; if it is fully glazed, it should also resist staining, making cleaning easier.

2、Toilet Hardware and Accessories

Pay attention to the hardware of the toilet, most of which is located inside the tank, so you cannot assess quality from the outside. Test the flushing mechanism to see if the buttons feel stable and responsive. If they feel cheap or lack elasticity, they may break easily. Conversely, buttons that feel solid with good elasticity indicate higher quality.

3、Difference Between One-Piece and Two-Piece Toilets

Note the structure of the toilet. There are one-piece and two-piece designs, which differ primarily in the tank. Two-piece toilets tend to have higher production rates and are generally more affordable. One-piece toilets have lower production rates and are pricier, so your choice should depend on your specific situation.

4、Siphonic vs. Direct Flush

Pay attention to the flushing method of the toilet. You can choose based on your needs; for instance, siphonic toilets offer quieter operation with higher water levels but can lead to water wastage. In contrast, direct flush toilets might be noisier but are more water-efficient.

Conclusion：That concludes our discussion about whether to choose a 300mm or 400mm toilet when the distance is 350mm. It is recommended to select a toilet with a 350mm distance for proper installation.
