Once I was stitched up and everyone bar one midwife departed, someone changed the sheet/bed protector thingy under me. I was in a hospital gown and was given a big pad for between my legs. Oh the dignity!
I was given a sandwich [no toast either] and a cup of tea. It was about 10pm though. I'd have chewed my own arm off by midnight if I'd only gotten toast.
There was a shower room / ensuite off the delivery room so once I was a bit more "with it", DD was dressed etc I was encouraged to have a shower. DH was holding DD and I couldn't face rummaging for a washbag in my hospital bag but some lovely person had left a tube of hanging shower gel stuff like Radox and I think I washed my hair with that and just cleaned up.
There was blood but not gallons of it. Just enough like a heavy period where you stress about getting blood on the towel [supplied by the hospital but I didn't want to re-emerge with some item covered in blood]. Fine though - you just need the wherewithal to remember to take big pants and pads into the shower room with you.
I remember it was a smallish wet room with a really crappy shower curtain with a plastic chair, so it was a nightmare to keep stuff dry in the room ! Best shower of my life though 
Midwife was in the room or popping in and out the whole time. It was a fairly quiet night for them I think but until you are off the labour ward they were keeping an eye to make sure you didn't keel over.
My tip would be is to get a ziploc bag with an all in one shampoo/body shampoo bottle, toothbrush and toothpaste, a comb for your hair, bobbles in case you leave it to shower the next day, couple of maternity towels and a pair of big knickers so you can take it all into the shower room with you. There is no way you are going to be putting on make-up and there is usually no where to put anything down
