    Light Niche Prior to Collar Pour?

    Should the light niche be installed before pouring the collar? And should the concrete come up around the bottom of the niche? My niche bottom is only 8 inches off the ground, so if I pour the suggested 10-12 inches it will be 2-4 into the niche.

    Not much info here to respond to. Are you building this pool? Do you have a PB?

    If the bottom of the niche is below the level the concrete will reach, the niche needs to be in place before you pour concrete.

    My info is in my sig Its a DIY 18x36

    The bottom of the niche will be below the level of the concrete, but I wasnt sure if it was normal setting the niche in concrete like that or if I should build a boxed area behind the niche to have the concrete not right up against it.

    There is no problem having the niche in place as long as you either leave the area where the wiring conduit attaches clear, or also have the wiring conduit in place in advance as well.

    I would recommend not having the niche bedded in the bond beam concrete

    I think ill put the niche in, and build some forms around it on the outside to keep the concrete several inches from the niche.
