WaterGuru skimmer cover

Our pool has a nice finished concrete deck and the skimmer cover is also concrete. Evidently, the skimmer came with a plastic form which the builder filled with the same concrete. (It wasn't just a mold; the thin edge of the plastic form remains around the concrete.) Replacing this cover with WaterGuru's plastic cover would be really ugly. Anybody with a WaterGuru deal with this issue?
