Bidets are common in countries where water is very expensive. There, instead of taking a shower, they use the bidet for anything below the waist including feet and use the sink for waist up washing.

If you want to feel clean, just hop in the shower. You can quickly wash your feet, or other places, with the shower head. This way, you don't need extra space for the bidet in your bathroom either.

Those million dollar homes with bidets are for owners with way more dollars than sense.
