Bsmt rough in.re:wood frame in concrete where tub piping is located.
My home was roughed in for a basement bathroom when it was built and I'm now in the process of finishing the bsmt.
There is a wood 12"x14" frame in the concrete where the bathtub piping is located a few inches under the gravel. The wood frame is not flush with the concrete and sticks up a couple inches above the concrete. I knocked out one side and then thuoght maybe I shouldn't have done that.
Can the wood frame be removed completely? The reason I ask is that I'm installing dricore subfloor panels so the wood frame protrusion poses a problem when laying the panels. I was thinking about removing the wood frame and laying the dricore over the opening making sure to cut the panels to have access to the piping below. Once the plumber installs the proper connections do you fill in the 12x14 hole with concrete or gravel?
Thanks for your help.
