I saw Anna's slatted bench (and other members brags) and thought I could adjust the design for some hot tub steps.
The design is simple but effective, (but very heavy).
It is slightly more complex and the cuts need to be pretty accurate, (which mine weren't), but you can sand away most mistakes.
I ended up putting adjustable height feet on each leg. This assists with height but also keeps standing water off the wood.
Anyway, I put see through grip tape on the steps to avoid accidents and overall it does the job.
