Building a roll-in shower? Read on for important Ohio Building Code changes…

Will your building have a roll-in shower? If so, are you aware of this update to the OBC?

OBC for Roll-in Showers: The Bottom Line

For roll-in shower requirements, the 2011 Ohio Building Code (OBC) references ICC/ANSI A117.1-2009. The 2009 version of ANSI A117.1:

  • Requires that all roll-in showers have seats
  • Requires that the showerhead and controls be located on the back wall of the shower (the wall adjacent to the seat)
  • Does not offer an alternative for a roll-in shower without a seat

See the ICC/ANSI A117.1-2009 for complete code details.

Background on the Roll-in Shower Code Change

The 2011 OBC is based on the 2009 ICC. Both codes reference ICC/ANSI A117.1. This document discusses plumbing fixture controls, grab bar locations, and other accessibility requirements.

However, the 2011 OBC references a different version of ANSI A117.1 than the previous (2009) OBC code cycle and the 2009 ICC.

The 2009 ICC references ICC/ANSI A117.1-2003. The 2011 OBC references ICC/ANSI A117.1-2009.

ICC/ANSI A117.1-2009 has the requirements listed above.

Following the OBC: Roll-in Showers

It’s a situation where one number makes all the difference.

As the above illustrates, the OBC will occasionally reference a different version of a standard than the ICC references. That’s why it’s important that designers always review the underlying standards and not assume that the state code always references the same version as the international code.

Keep up on code – share this with your colleagues.
