Yes. The basin waste (slotted or unslotted) connects to a bottle trap or P-trap below, which provides the water seal to prevent odours and connects the basin to the main waste pipe. You can purchase one from us, here.
Really pleased with the quality and the delivery would recommend
Good quality piece , for my disabled mum so needed a non slip stylish bath mat for her , I am very pleased with my purchase
I love this so stylish and much cleaner I would highly recommend worth the price.
