Fitting 1.5 bowl sink and drainer into base unit problem (2025 Update)

Perhaps I should have made it clearer that only the 2 x bowls are supposed to sit within the base unit. The flat drainer will almost just sit on the work top above a space for a dishwasher.

Is the issue with the front - back distance of the 600 base unit? - the reason I ask is that some base units have a strip of chipboard (say 18mm x

It's not unusual to have to butcher base units under sinks. Providing they're bolted to complete units either side, or fixed to an end panel, stability isn't normally compromised.

At the top of the base unit, front, there is a cross member 56.5cm x

This base unit, is deignated as either a base unit, sink unit or hob unit. (multi purpose without any adjustments or extra pieces)

It is as selected by the wickes planner.

I don't think there is any way I can reposition the cross member at the front unless I was to drill some holes, but I will look at this option.

I tend to think I will have to lower the back board by about half and give the exposed chipboard edge a good coat of varnish.

Ooops!

Should have said "Yes", it is an issue with the space between front to back. Side to side seems ok.

I ran into a similar issue when trying to fit a 1.5 bowl sink with a drainer into a standard base unit, it’s trickier than it looks!

The first thing to check is the width of your base unit. Most 1.5 bowl sinks need at least a 600mm unit, but depending on the design and depth of the bowls, you might actually need 700mm or more to fit it comfortably, especially if the drainer is on the same plane.

Another common issue is the position of the support panels inside the unit, sometimes they interfere with the second bowl or the waste fittings. In my case, I had to trim one side panel slightly (carefully!) and reroute some of the plumbing to make space for the waste trap.

Also, make sure to check if your worktop has enough space to accommodate the overall width of the sink + drainer combo. If it's a tight fit, consider getting advice from a professional or checking this helpful guide I found. Click to view more

HOH for the win!

Just in the nick of time - not having a functioning sink for the last 17 years must have been really getting on the OPs t*ts!
