What is the depth of these stairs? I am purchasing a Catalina Swim Spa, but need steps that are narrower than 36 inches. Thanks

This 4 step swim spa step is 50 inches from front to back, height to top step is 32 inches and height to top handrail is approx 54 inches. If you need a smaller step from front to back, please check out the 3 step version: http://www.spasandstuff.com/spa-accessories/hot-tub-spa-steps/signature-spa-steps.html
