Any "big, panic" style buttons that are Zigbee or ZWave?

Most of what I see for Zigbee buttons are usually this size - https://amzn.to/4s5v7Lb - basically the housing is not much bigger than an inch or two overall, and the button is an even smaller area inside of that. I have a number of them in my home, and they work fine for what they are.

But I have an "edge" use case where I could use something much bigger / more prominent. Maybe even something big and red. Still just need it to be a basic zigbee switch, however.

My use case ... is that my 90yo mom who insists on living independently, she recently had a toilet overflow and damage her bathroom. It's a costly repair. She's not agile enough if the toilet were to overflow again, to reach down and crank the valve off - so I was thinking about putting a whole-home monitor and controllable valve in and then can just build some logic in Home Assistant for an "emergency water off" if needed. Pressing the EWO would, of course, alert me as well.
