I wish to have a good drain for a concrete floor how deep does this drain need to go for best use.thanks
Dear Customer,
Total height of this drain from the very bottom of the included siphon trap to the top edge of the frame is 88 mm. You need to cast it in concrete, so the stainless steel flange surrounding the drain is just above the concrete level. Concrete layer needs to be 73 mm thick or more.
If you have any questions I will be happy to help.
