Earlier in the year I supported a client at a home water birth. They had a birth pool, so to protect their flooring they had bought some self-adhesive carpet protection roll. You know, the stuff that decorators use. It took me and my client's husband a matter of seconds to cover the entire floor, and once it was down it stayed down. It didn't budge at all until I pulled it up after the birth, it provided grippiness so we didn't have to worry about slipping over (unlike tarp or shower curtains), it didn't make annoying crinkly noises and, of course, it protected their floor. And when I did pull it all up it left the carpet looking like it had been freshly vacuumed. Bonus!...
