Instructions for putting together were unclear + couple of holes were in wrong places so husband had to correct it. Now completed, there is a piece of wood that juts out below the tiny drawer - this edge is rough, unfinished piece of wood - there is no other way this piece could have been fitted! If i pull the drawer and the slide-out shelving up to the edge of the wood it is not as noticeable. 
I've tried two types of toilet rolls in the top compartment and neither fit in. However the bottom slide out shelving is deep enough to fit a bleach bottle, disinfectant spray etc. 
Tbh the cabinet is not as useful as I'd hoped but I can live with it for now!
