/jp/ - Otaku Culture

So I'm having a house built and would like to have the bathroom in the Japanese style not only because I find it aesthetically pleasing, but because it seems water/energy efficient. This probably belongs in /diy/ but I figured I'd bring it here and see what you guys thought first.

What recommendations do you have as far as construction goes? How difficult would it be to convey to the people building the house exactly what I want, given that it's not a very common house feature where I live (southeast US)? How do you think the cost will compare to the standard western bathroom? Any other comments welcome. Even the faggot comments. I need a good laugh.
