   If you don't want to figure it exactly put it in at 19in. off the floor. This is low, but it will allow you to hook up the vanity; put it in too high and you are fxxxed, luck.

   I was told by a plumber, the height of your hammer handle

   That depends on how long your hammer is.

   The self-rimming lav manufacturer should have a rough-in guide that looks like this:

   In this case the dimension for the drain outlet is 14 5/8" down from the rim - your mileage may vary (check on-line via manfacturer).

   To know about the bathroom sink plumbing rough in heights you must understand that sink drain lines should be between 18 to 20 inches. The water supply pipes must be some inches higher and it should be 20 to 22 inches from the bathroom or kitchen floor and it is generally installed to the drain line sides. This height is compatible with most bathroom sinks.

   For a 34"" high vanity, the drain is typically stubbed out at about 18"" to 20"" from the floor to the center of the pipe. This allows enough room for the P-trap and ensures proper drainage alignment.

   I recently needed affordable plumbing services and found a great deal through this comparison website. It made finding the best and most affordable plumbing services super easy.

   Always look at the cut sheet of the sink and the vanity going into the space. You’ll get your answer there, no sense in guessing.
