A bowl with no tap hole, and that is the point
The best countertop basins for 2026
A countertop bowl sits on the worktop and is plumbed through a single hole cut beneath it, which means it comes with no tap hole of its own — the tap is a separate decision, and it has to be tall enough to clear the rim. Rim height is therefore the first number to write down, because it sets the minimum spout height you can buy afterwards. Then the ordinary geometry: outside dimensions against your worktop depth, and bowl depth, which decides splashing more than anything else. Two details that catch people: the waste hole diameter, near-universally 1"1/4 but worth confirming, and whether the bowl has an overflow. A bowl without one needs an unslotted waste, and fitting a slotted waste to it leaks into the cupboard. Weight matters on a thin worktop. We compare outside dimensions, bowl depth, rim height, waste hole diameter, whether an overflow is present, material, and weight.
