Is is possible to install sheet flooring in a laundry area that has a floor drain? My concern is that the area around the drain is sloped and how would you manipulated the sheet flooring to adhere flat in the sloped area?

Depending on slope to drain and type of sheet goods, use a heat gun on surface. It will make goods plyable and will conform to slope.

If u have a piece of scrap, try on that first.

Good luck
