One thing about concrete once it is poured there is no turning back. Never know what the future might bring. I stubbed in PVC pipe in concrete and out to the outside under ground and later fed a water line up through it and stubbed up drain next to that that tied into floor drain system. I put two drains in my shop. One drains west half and one drains SE corner. The NE quarter of the floor is flat for my lift. My concrete guy said he had a customer that demanded his floor sloped to the doors he told the customer it wasn't a good idea. Customer didn't care they poured it his way and the doors froze shut. It gets pretty cold here. Hope that helps.
