One: Is it necessary to purchase a large-capacity sink?
Not necessary.
It's not necessary to buy excessively large toilet bowls, especially in small bathroom spaces. While a larger toilet bowl might seem appealing, it's impractical and takes up valuable space. Therefore, it's best to choose a toilet bowl that is appropriately sized for your bathroom.

Two. important considerations when selecting a sink.
1、Select appropriate materials.
Currently, commonly available toilet cisterns are primarily made of plastic, with small quantities being made of stainless steel or ceramic. Ceramic cisterns are expensive and bulky, making them less practical. Stainless steel cisterns are aesthetically unappealing and can detract from the bathroom's appearance, so they are rarely chosen. Therefore, polypropylene (PP) plastic cisterns offer a durable and cost-effective alternative.
2、Water is a critical factor.
How reliable are the flush tanks for squat toilets? What is their performance like? The key factor is the core components of the flush tank. These components are essential for both flushing and water storage. If they are poorly designed or of substandard quality, they can not only prevent proper flushing but also waste water resources. Therefore, when selecting a squat toilet flush tank, it is important to check whether the components are designed appropriately and whether they meet quality standards.
3、Styles are selected based on the space.
Currently, there are two main types of toilet flush tanks available on the market: wall-mounted flush tanks and concealed flush tanks. For small bathrooms, it is recommended to choose small-sized or ultra-thin flush tanks, or concealed flush tanks. For larger bathrooms, there are no limitations in terms of size or type.
