We have separated toilet and bathroom in my hdb flat. There's not provided floor trap in our toilet room. Now we have to make a hole in the wall between toilet and bathroom and the water flow from this hole to the bathroom. But not all the water are not flowing to the bathroom. Can you help me to solve if you have better idea about this?
Thanks,

Can you reword your complaint for us? It's confusing to say the least.
What "floor trap are you referring to?

Are you saying you have no water in one bath so you made a hole in the wall and ran a pipe through it to supply the other one?
Please post again. Tom

I mean bathroom for showering and washing things and toilet room for water closet only. My hdb flat have 2 separate rooms for bathroom and Water closet. My water closet room hasn't got the floor trap, only bathroom have it. So, we make a hole at the wall between this two room and Let the water from the w.c room flow to the bathroom. You have any other better idea for flowing water to bathroom rather than make a hole...
Thanks, Zin mar

Zinmare,
What country are you in? Toilets have a built in trap. I don't understand what "floor trap" you're referring to. Regards, Tom

I mean floor drain.. Normally one bathroom should have one floor drain? Mine doesn't have this. Can easy to install new Floor drain for this room?
