Backpains, why the suit at all? I thought you had your set up in a "tub Hut" your husband built and had privacy once you were inside? Why not just go out with a robe and once in the tub hut go "Au natural"? All the cool tubbers are doing it.
This works:1. Get in with suit on2. Turn on bubbles3. Take suit off4. Enjoy an obstuction-free soak5. Put suit back on6. Turn off bubbles (or not)7. Get out with suit on
