What Is a Basin Overflow?
Basin shopping means choosing a colour, shape and style you love — but there's one practical detail worth understanding first: "overflow" or "no overflow." Here's what it means, in plain terms.
What Is It?
A basin with overflow has a small hole near the top rim. If the basin fills up too high, water drains through that hole instead of spilling over the edge.
Why It's Useful
It's a simple safety net for moments like:
- Leaving the tap running by accident
- Kids forgetting to turn off the water
- Getting distracted mid-task
Overflow vs No Overflow
With overflow:
- Prevents accidental spills
- Needs a slotted waste
- The hole can collect a little grime over time
No overflow:
- Cleaner, simpler look
- Needs an unslotted waste
- You'll need to keep an eye on the water level yourself
Busy household or often distracted? Overflow is the safer bet. Prefer a clean look and don't mind watching the tap? No overflow works just as well.
How to Tell Which One You Need
- Check for a small hole near the basin's rim
- Check the product listing — we always note "with overflow" or "no overflow" clearly
-
Match the waste — overflow basins need a slotted waste; no-overflow basins need an unslotted one
