How to reinforce floor for cast iron bathtub?
I'd like to replace the acrylic alcove tub in our hall bathroom with a nice cast iron tub but I don't know if the floor can withstand the weight.
We live in a typical single-story ranch built in 1993. We have plywood subfloors with a (dirt bottom) crawl-space underneath. I don't know the size/spacing of the floor joists without crawling under the house but I'm sure their pretty standard.
Since we plan to DIY our bathroom remodel, I'd rather not have to hire an engineer to tell me if my floor is strong enough to support a >350 lb. tub filled with water.
Should we play it safe and reinforce the floor? If so, what is the best method?
Thank you in advance for your expert advice.
