How many angle valves does a typical bathroom need?

When renovating the bathroom, people usually focus on the toilet, bathroom cabinets, shower heads, etc., as these are the major items. However, the small angle valves are often overlooked. Despite their small size, they are the crucial guardians in the water system. For the maintenance of bathroom fixtures and to prevent water leakage, these angle valves are indispensable. If the quantity is not planned properly in advance, adding them later will not only damage the wall but also affect the overall appearance.

In an ordinary family bathroom, a toilet must have an angle valve to control the water supply independently. In the future, when repairing the toilet, you won't have to turn off the main water supply of the entire house. The cold and hot water faucets on the bathroom cabinet need one each, totaling two angle valves. Many families will also install a toilet flushing spray gun, and here, an additional angle valve is needed. The concealed and pre-installed shower mixing valves generally do not require additional angle valves. If it is a visible shower faucet, an additional configuration is necessary.

The basic version with sufficient capacity requires 3 to 4 angle valves to meet daily needs. If the bathroom functions are relatively complete, preparing 5 to 6 angle valves will be more convenient. If conditions permit, a reserved position can be set to facilitate the addition of water-using accessories in the future. Angle valves are concealed hardware, and the quality must not be compromised. Priority should be given to choosing brass as the main body, which is resistant to pressure and corrosion, significantly reducing the risk of water seepage and leakage. If the planning is done well in advance, many waterway troubles in the future can be avoided.
