Loved your "article" on Bill Gates, being a Limey by birth I really understand the English bathroom!!

I have a Hydro Swirl bath (oops tub) which I guess was installed about 15 years ago, it is very similar to the one in your installation diagram. the tub has 5 jets which had brass trims which now look worse for wear and I have pulled them off. Do you know if it is possible to get replacements?

Thanks, Colin
