谢谢邀请！

老房子及装修中没处理好的卫生间反味，是一个比较常见的问题，给人们的居家生活带来不少烦恼，某种程度上，也影响了现代品质生活的质量。

常见的卫生间反味问题，可以通过下列一系列方法加以改造，改进，避免。

1.针对卫生间洗漱，洗手台下水反味的改造，改进。

1）对卫生间下水管的改造。

如具有可行性及改造条件，可以将原不带存水弯的下水管，通过增加存水弯，重铺下水管，形成水封，从而阻隔反味。

不过这样的改造动作比较大，需拆除原贴好砖的地面，墙面，原下水管，加存水弯改造，重新布设下水管后，还需要新浇地坪，做防水，进行蓄水试验，再行贴砖，如果原地砖，墙砖无备货，新购砖或难配成一致的，总体来说，操作比较麻烦。

2）更换带存水弯的下水连接管。

如果原下水不具备改造的可行性，不具改造条件或拆除改造动作较大，你想省点事，减少成本，也可直接更换下水连接管，即从洗漱下水口至下水管口的一段连接管道，大多为塑料或不锈钢软管等。

购置现成的带存水弯的下水管是比较简单易行的方案，可以交由水电师傅安装，动手能力比较强的你，自己也可以按照安装说明安装。

不用动大动作就可以消除卫生间洗漱部分反味的烦恼。

2.针对卫生间地漏的改造。

如果卫生间未采用防臭地漏，反味则可能源自地漏。

1）更换防臭地漏。

具备地漏更换条件时可拆除原地漏改装防臭地漏。

原来的非防臭地漏位置，可根据实际情况改装防臭地漏；

新装修的卫生间，记得要一步到位安装防臭地漏，去除以后的地漏反味烦恼。

防臭地漏的更换安装可以交由瓦工(泥工)师傅负责。

2）加装防臭地漏芯。

如果需要避免更换地漏对原卫生间地面造成的破坏和修复，可以采取不更换地漏，只加装硅胶防臭地漏芯的方法。

这种硅胶材料地漏芯受到向下的水冲后自行张开，可以顺利排水；正常状态时则自行粘连闭合，阻挡自下而上的臭气及小虫虫，从而实现防反味，防臭，防虫。

硅胶地漏芯还可以根据地漏下水管道的不同深浅进行相应的裁剪。

无论是淋浴房的下水地漏，还是卫生间干区，湿区的排水地漏，都可以采用这种防臭地漏芯，安装起来也简单易行，看懂安装说明，你自己也可以动手安装。
