why multiple toilets at home is a good idea....

Ассенизационно-Санитарная Устанdовка (ASU) or the waste management unit in the Zvedza Module of ISS( International Space Station) failed to suck human dump on 21st May. Being the only toilet aboard ISS, the crews were stranded, and despite crew's best attempts ( Duhh!!!) NASA admitted that things are not going so well. Almost all parts were replaced, but the problem seems to be with the ASU separator Pump.

The three astronauts aboard ISS were forced ( I imagine why? ) to use the toilet in the moored Russian Soyuz Capsule in the Orbiting station.

Meanwhile NASA packed replacement parts aboard Discovery shuttle, which is scheduled to blast off soon.
