Regretably we installed a caroma dual flush one peice toilet where it is more or less surrounded by three walls for a small degree of privacy - we did all this before attaching the toilet seat and now can not adequately tighten done the seat as the only access to the bolts is from the back of the toilet and then back quite a ways towards the front. There is about seven inches between walls and toilet. The look is of course great because the bolts and such are completely out of sight on the interior of the full skirt. Any suggestions? Any special tool thatmight be of some assitance? Tried getting a smaller child to shimmy his arm in and around to no avail...
