As already mentioned in the other reviews, the minimum altitude of 230cm is very strong understatement. My bathroom is ca.260cm high and even I had great difficulty in the strong springs to push strong enough together to set up the shelf properly. There is now but Bombenfest and I can not complain for the price.
Since the shelves are held Allerding "only" of rubber, may be the Regal probably not too heavily loaded. Otherwise, there's always the possibility just to drill holes through the rods and bolts in. Then you should really keep everything.
