If you showered more than once a week it might not be such a problem.
And my kitchen sink blew up, too.
That's a disposal and a clog in two days. The disposal was just bad luck. It rusted out and then shorted, and then the magic smoke escaped. I think the clog might be related. The Binford 6100 Brick-Shredding Badass Disposal Of Awesomeness I put in (1hp Waste King that sounds like a 757 when they hit the throttle for takeoff) pushes a good bit more pressure down the drainpipe and may have dislodged something. I snaked it about 20' and couldn't find anything, but the drain clearing bladder blew whatever it was right out. Best $12 I've ever spent.
