Hi everyone, its my first post here and i just wanna open up a topic about house building in japan. I'm not really new to prefab house building as is also quite common in countries other than japan, but what really amazed me is the prefabricated toilet/bathroom in almost every japanese house (not to mention all the high tech gadgets in it). I really like this kind of toilet as it needs only little maintenance and cleaning unlike the traditional tiled toilets or bathrooms. I'm interested in knowing how these prefab toilets are manufactured and the kind of material used. I bet its not ordinary plastic. I hope to learn something from this forum not only about japanese toilets and bathrooms but also about japanese house building in general......thanks a lot and chow!
