Looking to get a vanity unit similar to this http://soak.com/1200mm-blanc-matte-white-combined-suite--sabrosa-ii-pan_p31322142.htm but my soil pipe goes into the floor. Is this ok? Our currently toilet stands out around 4 inches from the wall (with boxing in behind for support, soil pipe is approximately the same distance too) and it has a right angle pipe from the toilet to the drain. Thanks!!
