My previous house had a wall-mounted toilet in its one-and-only bathroom. Yes, nice for mopping beneath it.
However . . .
My late husband, who was a big guy, had a night of intestinal problems. He spent hours in the bathroom, unknown to me, as I slept through it. Until about 5 a.m., when he woke me to say he had fallen asleep and half fell off the toilet, causing it to break off the wall.
We lived an hour from a city. I called a plumber on his 24-hour line at about 5:10 a.m. I clearly woke him up. He drove the hour to our house. I would have liked to switch to a floor-mounted toilet at that point, but it would have required major plumbing surgery, and we needed a toilet quickly.
Then the plumber drove the hour back to the city to get the only wall-mounted toilet he could find in stock, an hour back to our house, and installed the thing. He wouldn’t take any extra money for all his trouble.
Meanwhile, my poor husband was relegated to a drywall bucket in the garage.
I would never have another wall-mounted toilet.
