The requirements for showers in Option A bathrooms are the same as
those for Option B bathrooms (Section 1004.11.3.2.3.2) 2. In type
'B' units, when there are multiple bathrooms in the unit, Option A
clearances would apply to all bathrooms within the unit. On the
other hand, if Option B was selected for a unit with multiple
bathrooms, the Option B provisions would apply to just one bathroom
in the unit. All bathrooms must provide blocking for the future
installation of grab bars.
Reinforcement shall be provided for the future installation of grab
bars at Units Type 'A' (Section 1003.11.1) and Type 'B' (Section
1004.11.1) 4. The blocking must be sized to cover the range for the
height of the grab bars and the minimum lengths. Allowance must also
be made for the attachment of the grab bars
