I'm looking to build a set of steps for our spa. I could probably do it without plans, but it would be much appreciated if anyone has some plans they are willing to share.

This is really a simple thing to do, either a box built out of deck boards and treated 2x4's... or come up with your own. Most of the time, a spa step needs to be nothing more than a short one level platform to make entering/exiting the hot tub a little easier.
