I removed our old faucet from our roman tub as it was nearly 20 years old and wanted to replace it. I do not know what brand it was. I foolishly assumed that the fittings / fixtures would be universal but I was wrong. I purchased a Pfister Serrano tub "Trim Kit" and it will not mount to the existing fixtures. I would much prefer to use the existing fixtures as it will be much more simple so buying another brand / style is of no issue.
I have attached a pic of what is currently on the tub. Any advice or direction is greatly appreciated
Thank you very much!!!
