My question pertains to the washing machine box rough in with supplies and standpipe. Under normal rough in this box usually ends up around 42 -48in., but what about todays pedestal washers putting them at a height of 53in.? Is there a standard rough in for these, as the 42-48in. height would be too low for the standpipe. I'm guess I'd need the bottom off the box at a minimum of the washer height of 53in? Thanks
