Wall-hung toilets are expensive and the installation of water tanks is troublesome. If there is no special preference, it is better to use the floor toilet. Siphon toilets are more expensive than flush toilets, and their advantages are quiet and relatively clean (in fact, you can't tell). Flushing toilets can throw paper, and the better ones are quiet.

In fact, these problems of the toilet are not important, but the style and price are the most important. It's similar to use. LZ is so particular about buying a suite, but the bathroom needs to be big to look good.
