Bathroom fixed in our 75 year old house.
It had a cast iron tub that we don’t know when was put in, but the porcelain finish on it was worn off, mostly, making it stain and impossible to clean. The contractor said it weighed maybe 400 lbs. (181 kg). He had to saw it up.
Floor and walls in bad condition from leakage.
All fixed up now with new walk-in shower, complete with grab bars for my old ass.
