Hoping to get some expert help from the group - looking for experience on putting in the "extended vanishing lid" for a retractable pool cover.

Our pool is dug, rebar is up and we just got the specifics on the vanishing lid that we are getting (from cover pools). We had thought that we were getting the lid/leading edge that fully disappears under the coping - this is described in the cover pools brochure as the "extended vanishing lid" (which we didn't know at time). We asked our PB about it during the contract and were told that the it would not be visible. In fact, we are getting the "vanishing lid" - which means the box is buried, but the leading edge of the cover is clearly visible, which is not the look we are going for. It also means there is about a 12" gap between the coping and the water (filled by the cover, the cover edge, and what will be a tiled wall) - which feels like a little bit of a safety issue for small kids jumping in (of course we'll tell them not to jump in from there).

Our PB is trying to be helpful, but is coming back saying we need to raise the height of the pool and the skimmers to accomodate the extended vanishing lid - so a fair amount of rework and of course cost.

Does that make sense? Is there a cheaper way to build in the extended vanishing lid? Is it worth the extra cost?

Thanks so much!!
