This is a lovely over the toilet cabinet.  It was easy to assemble.  However because of the placement of my water connection to the toilet, I had to assemble everything but the bottom crossbar and put the unit in place.  Then I installed the bottom crossbar - no problem.  The doors slide smoothly.  It really is attractive and well worth the price.  I was happy to see a back lateral brace behind the back wall. So many times you'll get warping but not with this product.  Very satisfied customer.
