I am planning to get a stainless steel pool ladder. Is it a good choice?
Yes, stainless steel pool ladders are quite reliable. They don't rust or corrode, and they're stable as well.
Definitely a good choice, but only if they're made of marine-grade stainless steel. Other types may still corrode in salty or chlorinated water.
I have one and it's great, although you need to be careful when climbing, especially when wet, as the steel can be slippery.
