15" tread, 1' riser with a wet deck from the spa.

Thank you. You are referring to the three stairs on the right side by the lounge chairs? How big is the initial step off the patio into the pool, please as well. My swim spa will be 7x21 with 42" of water. I think these stairs down the side would be perfect and not eat up too much space. Thank you again.

With that width, I would offset along the wall, not jut out. Just have the steps staircase down along the wall like a swimout not go out into the limited active area. All steps should be no more than 12" risers.

Im not sure I understand. Would it be alright if I called for further information? Thank you again for your time.

Please.
