Welcome to the club. You'll LOVE sand.
The only thing I'd caution people on, is to put down a plastic barrier under the sand if you have it right on wood. You'd be amazed at how much moisture their droppings have in them and that moisture will go right through the sand and eventually, will rot out the wood.
I used a plastic carpet runner that has those little spikes on one side. It's pretty cheep (I have a small house) and it's thick and durable. I have about 2 inches of sand in my house. And I go through there every morning and quickly scoop out the droppings and toss them into the compost. Probably not as critical in the winter but in the summer, I like knowing that they are not inhaling ammonia fumes from their droppings while they are in there laying eggs.
