Toliet time sensor?

I also wanted to mention that unless there’s an independence issue in encouraging him to remember to flush the toilet, which I would understand, there are now automatic flushing toilet devices for under $200 that reportedly work pretty well. These have become more popular in the last few years both because of home care for people with Alzheimer’s and, weirdly enough, because of the number of people who are training their cats to use the toilet.

Anyway, they aren’t perfect, but it might be worth considering. There are several brands of these now. The following one is just an example:

Web retailers that sell adaptive technology for those with disabilities may have additional ones. (I myself am quadriparetic, and I see ads for these in some of the wheelchair equipment catalogs, although I haven’t personally tried one except of course for the commercial ones in public restrooms.)

The Rubbermaid model (from their commercial division) generally seems to get the highest ratings, but is more expensive:

Note that these “automatic systems” come in three types. Ones that only work if you intentionally Wave a hand above the sensor. Ones that work automatically when the person leaves the area. Ones that can be set either way, like the Rubbermaid. So read the description carefully. For your case, you don’t just want “touchless,” you want “automatic” or “self flushing.”
