I bought the same 10' roman steps. When they were installed flush with the pool wall, the steps pitched toward the pool. Thus the top of the steps at the back of the steps (at the apex of the curve) are about 1.25 inches above the top at the pool wall. Did you compensate for this somehow? I'm thinking that there will be a problem when I install the coping blocks. If I set on step they will slope toward the pool. The rest of the deck, of course, will need to slop away from the pool. I guess you could attach to the concrete deck and leave a gap and caulk it. Just wondered if you had this issue and how you addressed it.
