求翻译：卫生间洗浴时水会溅到邻近的墙上，如没有防水层的保护，隔壁墙和对顶角墙易潮湿发生霉变。所以一定要在铺墙面瓷砖之前，做好墙面防水。一般防水处理中墙面要做30厘米高的防水处理，但是非承重的轻体墙，就要将整面墙做防水，至少也要做到1.8米高。 若使用浴缸，与浴缸相邻的墙面防水涂料的高度也要高于浴缸的上沿。是什么意思？

So make sure you before laying wall tiles, walls and waterproof. General waterproof wall waterproof to do 30 cm high, but the body is a load-bearing walls, waterproof wall do, at least, it should be 1.8 meters high. If using a bathtub, bathtub wall adjacent to the height of the waterproof coating and also higher than on the bathtub.
