There are many temples with stairs around the font which only lead to the area around the oxen and which are only used for maintenance and cleaning. These can be seen in the Jordan River Utah Temple, Ogden Utah Temple (at least before remodeling started), Provo Utah Temple, remodeled Logan Utah Temple, and many others. Most of these are really plain, but one stands out. The Washington D.C. Temple font has two curved staircases that have obviously been planned to work with the look of the font and I think they add a lot to the temple and enhance the baptistry.

Those are a few baptistry staircases.
