Looking for something to protect the floor under a hospital bed.

We bought a cheap area rug at Home Depot for something like $30 to put under mom’s hospital bed. It’s not slippery like a shower curtain, but still a potential trip hazard.

My late husband was in a hospital bed in our carpeted living room for the last 22 months of his life and under hospice care. I never had any issues with any "fluids" getting on the carpet, and never even thought about that.
Now he had a permanent catheter at that time, and I had a aide come every morning to put him on the bedside commode(still in the living room)to poop, and there was only one time that his catheter bag was leaking and I had to clean that up, but after that I just kept a closer eye on his catheter bags.
And the hospice aides would give him a bed bath twice a week, but no water ever got on the floor/carpet.
I'm not sure what kind of fluids(other than pee)you're concerned about, but if you have the chux pads(from Amazon or walmart.com)under your loved one then they should soak up any fluids before anything reaches the floor.
And the nice thing about a hospital mattress is that you can wipe it down thoroughly every time you change the sheets.

Medline Extrasorbs or Ultrasorbs for ultimate protection AND you can dispose of them.

I would use puppy pads. A shower curtain any liquids would run off when you tried to move it.

That could be a good option! Thanks, Way.

How about a plastic shower curtain liner ? Target has nice thick sturdy clear ones reasonably priced .
