Whatever you do, don't make the same mistake I did. The day that my sump arrived, I suddenly found that it can squeeze through the door opening sideways, but then I can't turn it!! I had to take out a vertical support to allow the new sump to be moved in. It is a really scary task to do as the stand top is immediately warped as I removed the vertical support. Luckily I managed to move quickly and hammered the support back in.
Whatever the sump dimension you ordered, make sure you got turning room in the stand.
