I am renovating my house and have moved my laundry. It is only small & consists basically of an 800mm trough cabinet, a 600mm front loader and a 900mm broom cupboard in that order.
I have put a 1400mm bench over the trough cabinet and front loader that starts at a wall and ends at the broom cupboard. This bench is from bunnings & was 2400mm which i cut down to size. i have had the bench for a couple of years and it developed a slight bow in it. My builder who is renovating my bathroom says i need to put in a wedge under the bench to bring the bow out as its not square and could be affectting the trough cabinet etc. I understand its not perfect, but is there any real need to have it 100% straight? and if so what are the easiest ways to do it (other than buying another $200 bench?)
