Tempered glass in bathroom

I have a small bathroom that has an exterior window (24 x 36) above and behind a toilet. The bottom of the window is about 46" above the floor. The shower is about 8 feet away on an interior wall. I was looking at windows at Lowes and the window guy told me that I would need to buy a tempered glass window since it is over the toilet. I was reading the IRC and it mentions tempered glass being required in doors and enclosures for hot tubs, whirlpools, saunas, steam rooms, bathtubs and showers, but nothing is said about exterior windows. Does anyone know if tempered glass is required? Any comments would be appreciated.

Off the top of my head, I would say no but that would probably be under a local code.

Generally tempered glass is only required on exterior windows that are low to the floor BUT as Pulpo said - local codes always prevail. Your permit office can let you know for sure.

I think the guy at Lowes is full of crap.

Again as local code dictates but in general any glass "opening" that can be considered as a egress into or out of room should be tempered glass. Typically a window is not considered an entrance or exit, but a door is and a window in a door must be plexi or tampered glass.

I also have a window above/behind my toilet at about the same height. When I had it replaced several years ago I was told that because it was withing a certain distance of the tub/shower it needed to be tempered glass. I don't remember the stated distance, maybe 18 inches, maybe 36 inches, maybe in between. At any rate, my window is within just a few inches of the tub.

It could be a state or local code.

This link might help but check your local code.

Windows over tub areas less than 60" AFF, or within 3' of tubs or 24" from exterior doors must be tempered, as well as what Marksr mentioned on windows within 18" of finished floor, or if the glass area is larger than 9 sf. Other local codes will prevail.
