每个卫生间的布局都是不一样的，所以卫生间下水管直径选择多少才合适？还是要根据自己卫生间的下水管以及马桶的排水管而决定。一般大多数的家用卫生间下水管都会选择四寸左右，其下水管直径大部分采用75或者是50mm，在安装下水管的时候，可以用某种材料把水管抱起来，但是会占用一定的空间，但包装下水管的作用就是可以对下水管起到一个保护作用，而且非常美观实用，就算是下水管堵塞了，拆卸方便。与小便器相连的下水管直径，为50mm，公称外径（dn）为50mm，如果dn是75，下水管直径也为75mm；与大便器相连的排水管管径dn为100mm，下水管直径尺寸为110mm；如果大便器的排水管是横管，那么排水管管径dn不得小于110mm，下水管直径尺寸也不得小于110mm；如果小便槽的排水管，连接了三个或者三个以上的小便器，下水管管径最好是不得小于75mm，下水管直径尺寸也是一样。一般严格的来说，家里卫生间安装的下水管直径不得小于75mm，是最好的。

下水，是卫生间里面非常重要的一个布置，同时也是体现卫生间舒适方便的最重要的一环。而在卫生间下水管直径的选择上，也有很多的注意事项。而现在一般所采用的下水管道材料都是PVC，内径为110，还可以用内径为120的管材。其实，卫生间下水管直径并没有什么标准规定，都是根据卫生间的布局，来选择不一样的卫生间下水管直径。这样才能更好的体现卫生间的排污、排水工作。卫生间水管直径有哪些？公称外径一般有90、75、50的。市面上通常所说的几分，是对于焊接钢管而言，因为采用焊接钢管进行布置时，上面的螺纹是英制的，所以才有了几时、几分的说法，而现在一般都不会去在意这个说法，而采用PVC水管进行布置时，都是用粘接的方式，比如卫生间下水管直径是90，市面上一般都称之为90的PVC下水管，如果卫生间下水管直径是75，则称之为75的PVC下水管即可，以此类推。所谓最新的卫生间下水管直径，其实并没有什么最新的下水管直径，都是现在一般卫生间中，常用的几种下水管直径。出水口外径32mm，进水管内径32mm，出水口密封盖60mm，管道的伸缩在40cm到110cm左右。而根据不同的马桶，在选择下水管直径的时候，也要考虑到下水管排污、进水口处与马桶的排水管，是否是一致，如果马桶的排水管的公称外径是110mm，那么相连的下水管直径也应该是110mm。每个卫生间的布局都是不一样的，所以卫生间下水管直径选择多少才合适？还是要根据自己卫生间的下水管以及马桶的排水管而决定。一般大多数的家用卫生间下水管都会选择四寸左右，其下水管直径大部分采用75或者是50mm，在安装下水管的时候，可以用某种材料把水管抱起来，但是会占用一定的空间，但包装下水管的作用就是可以对下水管起到一个保护作用，而且非常美观实用，就算是下水管堵塞了，拆卸方便。
