Renovation update: Fotile ducting hole opening and wet concrete top work
It is a pain ass for me because for fotile hood, we need to open 7" ducting hole and not the typical 6"

, after consult zheilwane, I told my contractor to open the 7" hole accordingly. The most difficult part for me to open this hole is actually to purchase a 8" PVC pipe, because either not available or they have to sell in whole batang of 10 meter etc... in which I only need 1 ft, so after hunting around in my area, finally I found the 8" PVC and able to purchase only 1ft hehe.
After that I show my contractor the hose and tell him I wan to fit the 8" PVC with the fotile hose as in the photo below, my contractor said "Thats easy, cut it and use wire to ikat, then put silicon to seal back, once dried up, can put into ducting hole d

so photo below are the hose, 6"PVC and 8" PVC for my ducting hole opening preparation

The yellow line is actually the place where my contractor cut the PVC then mod to 7" :hehe

After pasang to the wall, this is how the ducting hole looks like, you still can see there is a line over there.

My wet kitchen is pretty small, so wet work for concrete top also very simple
