By Royal do you mean ostentatiously ornamental and decorative? I don't know how to help you lor like that really, although, I've seen gold plated taps in Koon Hoe. I think they belong to the "American Standard" brand. You can check out Koon Hoe. The showroom is in PJ Sec 13 near some churches...

I agree with the previous commenter that very showy stuff could be very tacky lor... unless if the interiors are done up like an Austrlian courthouse then I think very hard to pull it off without looking quite pathetic lor!
