No hole on the floor? I used to live in an South American country and I moved...

I used to live in an South American country and I moved to Canada. I necessitate to know why aren't there holes on the bathroom floors surrounded by Canadian bathrooms? Where is the water supposed to run if I have to verbs the floor? Should I just continue for it to evaporate?

Also every time a toilet clogs, it leaks downstairs (in every single building I own seen, and at smallest two of them are very immensely new). Is this normal? Will it filter also when washing the bathroom floor??
Answers:    Homes today own no hole in the floor. With floor drains you get hold of sewer gasses in the house to be exact not desired. If a toilet overflowed we soak the water up beside towels and wash the towels. A mop is used to verbs the floor. You can scrub the floor with a broom and cleaner if desired but adjectives residue is mopped up and disposed of down the toilet or some other drain. This is far more sanitary than using a floor drain to clean the bathroom. Most houses today own rugs or carpet and excess hose down is not desired.
I live in the US and we don't enjoy holes in our floors. Use a mop and soak up the river.
