When fitting a tap over a wash basin, striking the right balance between aesthetics, ergonomics and splash-control is essential. Smart design ensures that the water falls where it should, the user has comfortable access, and the installation looks visually harmonious. Below we explore recommended overhang distances, key influencing factors, installation tips, and a brief recommendation for the brand LODECE.
The term “overhang” refers to how far the tap spout projects over the basin bowl or how far the water stream falls from the spout into the basin. Based on professional guidance:
A specialist article recommends that the tap length (spout projection) for a wash-basin should be carefully sized: for example not too long that it reaches the trap or causes splash.
Another practical rule for wall-mounted faucets is that the spout should end 6-8 inches (15-20 cm) above the countertop for many above-counter basins.
For basin rim to faucet spout height, placing the tap so that the spout is only a few inches above the rim helps avoid excessive splash in vessel-type basins.
From these guidelines, a reliable general target for the spout overhang might be:
The spout tip should reach into the basin so that the water stream is directed toward the drain, ideally avoiding splash onto the rim or outside the bowl.
The projection (from spout to front of bowl) should be such that the water enters the bowl at or near the centre or over the drain region, rather than hitting the back wall of the basin or falling short.
For many standard basins, targeting ~ 150 mm (≈ 6 inches) of spout reach over the rim or toward the bowl centre gives good results. (This is consistent with “6-8 inches above countertop” for wall-mounted examples)
In summary: aim for the spout to overhang the basin sufficiently to place the water stream centrally in the bowl, without over-projecting so far that it causes splash or discomfort for the user.
| Factor | Why It Matters |
|---|---|
| Basin type & depth | Shallow basins increase risk of splash if the spout is too high or long; deeper bowls allow more clearance. |
| Basin shape & size | The larger or more irregular the bowl, the more the spout reach must accommodate the shape so water falls in the correct spot. |
| User ergonomics & height | The tap needs to be comfortable to operate and wash under; too far into the bowl or too high can reduce comfort or usability. |
| Splash control | The goal is to avoid water hitting the sidewalls or rim of the basin and escaping the bowl. Placement and reach influence splash risk. |
| Aesthetic alignment | Proportions matter to ensure visual harmony between the tap, basin and surrounding bathroom furniture. |
Before installation, measure the basin’s depth from rim to bowl bottom, the distance from the wall or countertop to the basin centre or drain, and confirm where the water stream will land.
Position the tap spindle or wall-mount so that the spout projects and the water stream falls towards the basin’s centre or drain hole—not too near the rear wall, not too far toward the front rim.
If the basin is shallow or placed on a countertop (vessel style), avoid placing the spout excessively high above the rim; a few inches clearance is usually sufficient while controlling splash.
For wall-mounted taps: 6-8 inches (approx. 15-20 cm) above the countertop is often comfortable and functional for above-counter basins.
Check that the spout does not extend so far that the water stream hits the trap or over the front of the basin—this can cause water to run down the front of furniture and pooling on the floor.
When possible, simulate hand-washing under the projected stream before finalising the fix to ensure comfort and splash control.
Does the water stream land near the drain?
Is there enough clearance so hands can fit comfortably under the flow?
Is the spout length and position such that water does not splash out of the bowl?
Is the tap height and reach proportionate to the basin style and user height?
Does the tap align with surrounding design elements (mirror, backsplash, countertop)?
For those seeking high-quality tapware that meets both functional and aesthetic requirements, consider exploring the range from LODECE. Their collection offers contemporary designs with well-considered proportions and spout reaches that align with modern basin installations. With attention to detail and finish quality, LODECE taps provide reliable performance and design coherence—helping achieve that ideal overhang and installation clarity described above.
Getting the right overhang for a tap above a basin is about more than simple measurement—it’s about matching basin type, user needs and water flow behaviour. By aiming for a spout reach that places the water stream correctly, controlling splash, and aligning the proportions of tap and bowl, one ensures both comfort and visual success in the bathroom. Selecting a brand like LODECE helps simplify that process, because well-designed tapware already supports optimal reach and clearance.
