The kitchen sink is one of those tough plasticky things, I think called
a 1 and 1/4 one, with drainer/ 1/4 sink / full sink in that order.

The 1/4 in the middle has a rather worse for wear (battered) plastic
sort of top-less box thingummy, with drainage holes which came with the
sink. Might these things be replaceable?
