We have a separate tub and shower and our tub has a standard faucet as well as a spray head on a hose. I wanted to replace the spray head, but the replacement head I bought has the standard 1/2" threading and the current hose measures 1/4" smaller in outer diameter. Should I just buy and 1/4" to 1/2" adapter? I did not want to replace the hose as it requires me removing the paneling underneath the tub to get to the origin of the hose. I would need to use a utility knife and then caulk it back on afterwards, I just wanted a simple solution to replacing the spray head only. Any ideas or solutions are welcome and appreciated. Thank you.
