Is it OK to wrap the toilet wall with PVC board?

可以，但pvc板不适合用在卫生间墙面。PVC板使用寿命较短，而且防水的性能还不是特别好，易老化、硬度差、污染后难于清洗。比较难打理。

Yes, but PVC board is not suitable for toilet wall. The service life of PVC board is short, and the waterproof performance is not particularly good, easy to age, poor hardness, and difficult to clean after pollution. It is difficult to manage.

虽然pvc样式好看，安装方便，但是它是塑料制品怕碰，而且还非常吸尘，长时间擦拭会划坏表面亮光，还变色，一般底衬用方木固定，方木遇水好腐烂，用不到一年就烂掉了。

Although PVC is good-looking and easy to install, it is a plastic product that is not easy to touch, and it is also very dust-absorbing. It will scratch the surface light and discolor when wiped for a long time. Generally, the bottom lining is fixed with square wood, which will rot when exposed to water, and rots in less than a year.
