Hi,buyer, Thank you for your email. The inner diameter of the drain hole at the bottom of the drain is 3.1inch (79mm) and the outer diameter is 3.6inch (91.5mm). Water pipes smaller than 3.6inch can be used, because you can cut the drain hole under the drain according to the diameter of the pipe. Hope it helps. Customer support center Jennifer
