I am looking to have wedding cake steps put into the corner of my pool under the new liner that I am putting in. The pool company told me that they ‘discovered’ that my shallow end was not typical when they arrived this past week. My shallow end is 4’ which is clearly marked on the CAD drawing that I sent them - which included measuremts. They had ordered preformed corner cake steps for a 3’ shallow end. Their solution is to build a ‘cove’ on the final step which would make the final step into the shallow end 16” .... which is awkward and uncomfortable as the rise of every other step is 11”. I am trying to figure out if I am able to push back and get the preformed steps for a 4’ shallow end - do they exist?
