I just went to Walmart and bought a $8 shower hose with spray head on it. I discard the head and used the hose. Our inside hose was leaking at the tub end fitting. I'd guess this is a 1/2 inch hose but they seem to be standardized so it doesn't matter. Our outside hose seems to be original and is really stiff so I think I might replace that one too. The new hose is nicely flexible. If a Home Depot is handy you would probably have a better selection.
