The bathtub from China

This bathtub came all the way from China (via Germany) to South Italy. The price justified the shipment. But we probably forgot to buy some special accessory (tubes) that cost in Italy almost the same money we paid for the whole bath tub. I guess, I need to visit Beijing soon, not only to catch up with old friends but also to buy some hard ware for the bathtub.

PS: the voting for 'how to lay the parquet' is closing soon. I think we have a winner: version C (the mix).
