I've messed up. I ran a new waste for the basin to the soil stack. I've since installed plasterboard and and tiled over the wall. Now it has come to fit the sink, it seems I brought the waste out too low.



What's the best way to overcome this? Even with the adjustable bottle trap I can't get it low enough to align.

Any help greatly appreciated.
 
It’s not on show you have plenty of room in that cupboard to make something up
I just thought the same. I was always under the impression it’s better to have that quite low then too high up. Very often you get called out for a sink blockage or whatever reason and you see that you have got difficulties to put a proper trap in unless you install a waste and ripping the whole lot out.

I would do what Shaun says & cant/angle them of the vertical slightly which gives more play room & the trap will rotate. May need a 45 degree on as well.
Hope this helps,
Andy

You can get them in different lengths from good merchants

Unless the trap hits the board beneath it, extend the inlet pipe and lower the trap. If it does, can you lower, or remove, the board?

I would use solvent weld elbow/pipe/elbow to bring it up; then use a p-trap , which gives you much more flexibility of fit as you can articulate the two sections to suit.
Not really a problem here, try it when you’ve brought the new pipe in too high - doh!
