Is there an after-kit to extend (raise) a toilet from between the floor and the base of the toilet? We need to lift a toilet 4-5 inched and have it be stable.

Not all handicapped people can use a snap on raised toilet seat. We know a man
With Alzheimer who finds it impossible to pee down such a narrow hole. He is going
Outside in the middle of the night where he locks himself out and increases his risk
Of falling. Any suggestions?

This will raise the toilet about 3.5" Toilevator - raise the toilet, not the seat (http://www.dynamic-living.com/product/toilevator-a-raised-seat-alternative) Even with a raised toilet this person sounds like 24/7 supervision is getting near appropriet
