1. The color should be consistent with the grade. The colors of the four parts of sanitary ware such as washbasin, toilet, bathtub or additional ladies' room must be consistent, and their grades should be coordinated with the colors of floor tiles and wall tiles in the bathroom. Generally, the color of sanitary ware in bathroom is similar to or slightly lighter than that of floor tiles, so it will be more harmonious to choose the same brand and style for basin faucet and bathtub faucet. It is best to choose a single-handle ceramic core nozzle, because the ceramic core nozzle is more durable than the rubber core nozzle and does not leak water. 2. Keep consistent with the drainage pipe. Before choosing a bathroom, be sure to find out whether the reserved drain of the bathroom drains downwards or horizontally. If it is drainage, measure the distance from the center of the drainage pipe to the wall, and then choose the bathroom with the same distance, otherwise it cannot be installed; For horizontal drainage, it is necessary to find out the height of the drain from the ground, and the height of the toilet drain and the reserved drain should be the same or slightly higher to ensure smooth drainage. 3. Check the water-saving function. When choosing a water-saving toilet, there is often a misunderstanding that the smaller the water tank, the more water will be saved. Whether or not to save water depends on the size of the water tank. In fact, whether the toilet saves water does not depend entirely on the size of the water tank, but mainly depends on the design of the flushing and drainage system of the toilet and the accessories of the water tank. Some toilet water tanks are very small, but the flushing performance is very poor, so they can't be cleaned once, and they have to be cleaned two or three times. Some toilet water tanks are not small, but the water storage line of the water tank is very low, the flushing ability is very good, and it is also very water-saving. Therefore, whether the toilet saves water depends not only on the size of the water tank, but also on the introduction of the dealer. We should ask the dealer for the flush volume of the toilet indicated in the product inspection report of the national technical supervision agency. The flushing volume below 6 liters used in China is a water-saving toilet, which is 4. The 5-liter water-saving toilet is the most water-saving in China at present. 4. How to distinguish the quality of sanitary ware ceramics? Generally, the glaze of high-quality sanitary ware is smooth, and there is no flat pond, color difference, pinhole and lack of glaze. The sound made by striking ceramics with hard objects is crisp.

Inferior products generally have many pinholes, bulges, cracks and lack of glaze, and their appearance is slightly deformed (the basin on the countertop is uneven, and the toilet will shake left and right when placed on the ground, etc.). ), the trademark is vague, and the sound is dull when knocking, and there is no clear sound.
