Splashing is not always a sign of a faulty tap. It can come from the relationship between the outlet, the water stream and the basin underneath. Changing just one dimension may not solve it.
Look at the complete basin-and-tap combination
A tall tap above a shallow bowl gives water more distance to fall. A short reach may direct it towards a steep inner wall. An angled outlet can move the impact point beyond the vertical line beneath the spout. Compare all three rather than choosing by overall height.

Observe where splashing begins
At a comfortable normal setting, watch whether water strikes the basin wall, waste fitting or your hands. Note whether the spray pattern is even. Build-up at the outlet may disturb the stream, but cleaning methods and removable parts must follow the model's instructions.
Choose a replacement with evidence
For a new basin, compare its internal shape with the tap's dimensioned drawing. For an existing basin, record the hole position and take a side photograph. A smaller flow setting may reduce splashing, but it cannot correct an unsuitable outlet position or a blocked component.
Before you order
- Check outlet height above the basin, not only tap height.
- Compare horizontal reach and the direction of the stream.
- Inspect bowl depth, inner slopes and waste position.
- Ask about tested compatibility when a combination is uncertain.
Common questions
Should the water always hit the centre of the waste?
There is no universal target for every basin. Waste shape, basin geometry and the water stream influence splashing; use combination guidance where available.
Will buying a lower tap guarantee less splashing?
No. Lower height can change the falling distance, but reach, flow and basin shape still need to work together.
