Is it possible to replace the sinkhole only and not the entire sink?

Gautama

The en-suite bathroom's compact washbasin's sinkhole has broken.
I'm wondering if it's possible to replace just the sinkhole and not the entire basin?

what is broken, picture pretty useless

I think the poster means the waste/ plughole
I am wondering this too as we got the pop up kind and they are terrible- want to replace them with regular plug type ones.

I would have thought the answer is yes- you need to cut out the silicone from around the waste and lever it out, and replace. Am I right?

Are you talking about the trap? Judging from the picture there's no trap

I've removed the trap because the underside of the plughole that the trap attaches to, has broken.

To put it another way, at one end you've got the plughole, pictured, and at the other end you've got a threaded pipe (that the trap screws onto).
This piece broke.

Ok. I m sure I understand you now. The drain /plug hole can be replaced. You don't need to replace the whole basin.
If you are doing it yourself it's important to remove all of the silicone from around the plug hole on the basin before you fit the new drain.

Good stuff, thanks.
One last question, does the plughole piece screw into the basin or should I be able to break the silicone and knock it out?

It slots into the basin from above and is secured from underneath with a back nut. There should be a sealing washer as well above the back nut.

You usually get an O ring to go between the drain & the basin. These O rings don't like me & leak easily. I would bin this O ring & use silicone instead.

This shows you most of the job. I would put the silicone in the corner of the waste and not on the basin like he did, and about half the amount.

Make sure all existing is cleaned and dried fully before starting install.

+1 for that sealing device. Makes life much much easier.

Great stuff, thanks for your replies.
I've finally got around to removing the waste outlet and it came away easily. This wash basin is in my daughter's en suite. She's only two years old so the door is locked and it rarely ever gets used. Hence my lack of haste fixing this.
When I removed the old waste outlet I noticed that the silicon had also covered the overflow outlet, blocking it completely and rendering the overflow totally useless!
I must check the other basins and sinks in the house to see if the over flows work or not!

BTW, what's the best way of removing the old silicone from the sink?
I cut my fingernails last night so I'm getting nowhere!!!
Carefully scrape off with a screwdriver? Or a plastic knife or similar implement? Or wait for my nails to grow back?
Thanks again.

I've been looking for a tapered waste washer like this one (which also appears in the video's thumb) but I've found none in the usual hardware stores, and online I can only find 1.25" whereas I need 1.5". Ah well...

B&q stock the basin waste washer kits. You might not need one depending on the sink. If the sink is new generally the waste hole will be square and the fittings that come with the waste will work. Old sinks can cause problems, one recently I resorted to using plumbers mate to seal it, like in lots of the you tube videos, worked a charm.
