Easy to replace a sink with a washing machine?

[Bunford]

We have a bathroom in the basement of a new house and we are looking to remove the sink and place the washing machine there.

Is this a fairly easy and straightforward job? Anything to consider?

The sink already has hot and cold water inlet and a waste pipe that I am presuming I can re-purpose for the washing machine.

Waste pipe on a washing machine should be 40mm if it's an actual sink not a basin. Hot should be disconnected unless can be repurposed, so as to prevent a dead leg.

This is the current setup. It is a 40mm waste on the sink at the moment I believe, and it feeds into the toilet waste pipe, which is off on the right of the below photo.

The intent is to cut remove sink and cut skirting where the red line is, and then cut the pipes here too and then put in the connectors for the washing machine and waste here.

The second photo shows the current routes.

That’s a washbasin, not a sink.

Do you also plan to remove the toilet?

I believe building regs require that toilets have nearby washbasins.

The toilet is remaining, but is going to be replaced by a toilet with a wash basin on top of the cistern, as it's a small secondary toilet in the basement. It'll be replaced by something like this:

Check waste size, basins invariably are on a 32mm waste, which is unlikely to cope with the flow from a Washing Machine when it pumps out.
