Nowadays most brand of wc are come from China, even some well know faucet maker also placed some of their factory in China. Actually "brand" is a tricky thing, u can say anything of that brand come from, we not really going to find out how true is it, the most important thing I think is important is about that brand reputation and that company servicing. Friend of mine bought a wc from 1 of the shops in balestier, even the price is cheap but he found out the after service is sucked, he complained that better spent more buck to get a better service company. Lucky Khoon i heard they specialize in plumbing thing so far i know their service is not so bad. Maclaire definately came from China, Johnson from malaysia, Rigel i not very sure. CP-Uno also China, I heard that actually is clone from another brand in singapore that not so famous, should be fine if you like the design.
