I have an older vinyl liner pool that I am having relined. It has no steps, so we are looking for options. I see very few drop in steps for in ground pools, and they look bulky and clumsy. I also understand they can be pretty unstable. I am wondering if there are add on corner steps that can be easily added to the pool without major work. And what kind of expense should we expect? I am getting little to no information from the company we are looking at to replace the liner.
