The bathroom is 1m1 6m in size, in order to save space, I don t want to stick the wall tiles, please

It is best to do waterproofing, about the tiling or pasting, but to save space, you can not use sand cement paste, with tile adhesive, which can reduce a lot of thickness.

The space is indeed too small, and it is better not to put the washing machine here, after all, it is an electrical appliance. In the case of a washing machine, the upper space can be used, and you can make a finishing shelf on top to store chores.

Let's use waterproof paint. The inside of the bathroom should be painted from the floor to the top of the wall, and the other side of the wall should also be painted, not just the inside of the bathroom. This avoids water seepage into the wall as much as possible.

I think the better brands are the top ten brands, let me tell you what I've seen, Yuhong YUHON, Yuwang, Master, Henkel Celite CERESIT, these are the ones, and there are their brand introductions on the top ten brands online.

The bathroom is small, but if you don't stick wall tiles, the waterproofing may not be so good.
