What are the minimum requirements for a shower?

Thursday, June 21, 2018

The 2017 Residential Edition of the Florida Building Code (FBC) and the International Residential Code (IRC) have the following minimum standards for residential showers:

  1.   Not less than 30 inch interior dimensions measured from finished interior surfaces, with a minimum of 900 square inches floor area, except that a shower can be a minimum of 25 inches in one dimension if the total area is increased to 1300 square inches. Fold-down seats are permitted as long as the minimum 900 square inches is maintained when the seat is up. Shower heads, grab bars, soap dishes, and valves allowed to protrude into minimum required area.
  2.   Shower walls must be nonabsorbent up to 72 inches above the drain.
  3.   The shower access opening or door must have a minimum of 22 inch clear opening width.
  4.   A listed anti-scald, pressure balance (single handle) faucet required, set to maximum 120º F.
  5.   Finished floor should slope 1/4” to 1/2” per foot towards drain.
  6.   The finished curb must be between 2 inches and 9 inches above the drain level.
