sorry I did not state that well enough. The cabinet opening is 23" tall but then the sump will drop down inthe stand another 5" or so. Totalling about 10" between the door opening and the sump. The inside stand area is 33" tall by 27"long by 14.5" wide. I think I will have enough room to get in there to clean and remove things. But when I get home I will measure to make sure. I might have to still shorten the sump to like 18" or smaller. I am just trying to maximize by volume but it might not work like I want to we will have to see before I build it. If you take alook here of the stand you might be able to see what I am talking about. http://www.maast.org/index.php?name=...ic&t=15484 mainly the last two pics on the thread.

Thanks again
