604.9 Toilets and Toilet compartments
If toilets and toilet compartments are meant to be used by children, the Standards provides suggestions and guidance in lieu of using the "adult" guidelines. The guidelines for children's toilets are found in ADA/TAS Section 604.9. In addition, the grab bar heights for children are found in 609.4.
1) The location of the toilet measured from the side wall to the centerline should be between 12"-18"
2) The height of water closets should be between 11"-17" to the top of the seat
3) The outlet of the toilet paper dispensers should not be mounted lower than 14" and no higher than 19"
4) The top of the gripping surface at grab bars for children should be mounted between 18"-27" a.f.f. (refer ADA section 609.4)
There is an advisory table which divides these ranges into ages. It is not required to use the table, rather to use it as a guideline and optional.
Because these age designations are only advisory, a set of grab bars could be mounted at 27" max even if the toilet seat height was 11" tall. As my colleague Ken Otten pointed out to me, this is important to note "because it is almost impossible, as many designers and contractors have found, to mount grab bars any lower than 27 inches AFF while still maintaining the required 1 1/2 inches of clearance below the grab bar (due to the location of water closet tanks, flush controls etc.)"
He also pointed out "Although the advisory for dispensers is well-intended, it doesn't always work. For children 3-4 years old, the advisory specifies a reach range of 14" AFF for the toilet paper dispenser. If one were to mount a grab bar 18" AFF to the top of the bar, after taking into account the width of the grab bar and the 1 1/2 inches of clearance required below the grab bar, a toilet paper dispenser would have to be mounted no more than 15" AFF to the top of the unit, making it impossible for the outlet of the dispenser to be a minimum of 14" AFF. One inch is simply not enough room.
Even if we ignore the fact that the 604.9 Advisory gives only one dimension (14") for this age group, and apply the entire range given in 604.9.6 for dispensers - 14" to 19", it is still impossible to mount a grab bar at 18" and also comply with the requirement for dispenser mounting heights without violating the clearances required above and below grab bars in in 609.3."
