What’s the first move when a toilet bowl is rising?
If a toilet bowl is climbing toward the rim, does closing the supply shutoff help only if water is still feeding from the tank, or is there another first move? I’d be cautious about trying to plunge while the level is still rising, assuming the shutoff is accessible and can be turned without forcing it. If the water has stopped rising and is staying below the rim, does that change when you’d try a plunger?
I’m also curious when plunging is more likely to make a mess or push water over the edge. At what point would you stop trying and call for help rather than keep working at a bowl that’s close to overflowing?

The shutoff stops fresh water feeding the tank; it won’t remove water already in the bowl or stop water from a flush that’s still draining into it. If the level is still rising, don’t plunge yet. If you can reach the valve safely and it turns easily, close it; don’t force a stuck valve. Once the level settles below the rim, you can reassess whether there’s room to plunge without risking an overflow.
A plunger can push water up and out of a bowl that’s already near the rim, especially if the level rises with each stroke. I’d wait until there’s a safe gap below the rim before trying; if plunging makes the level climb toward overflow, stop rather than continue.
