Well, don’t laugh.  Rather than looking at the bathroom building code as a limitation, look at it as a way to let you know how far the shower must be from the tub or the sink from the toilet.

What we give you in this guide is a generalized look at common bathroom building codes.  We do not pretend to give you an entire set of codes, nor do we attempt to make sure that the code applies to every single of the 19,429 of the municipalities in the United States.  Yes, building codes do vary from city to city, county to county.  So, general guidelines, folks.

  • Minimum ceiling height is 7 feet.

Sinks

  • 4 inches minimum spacing from side walls.
  • 21 inches front clearance.
  • 4 inches minimum from another sink.

Shower

  • Shower floor should be at least 30 inches by 30 inches.
