We remodeled a Japanese-style toilet into a Western-style toilet in Soka, Saitama. Since Japanese-style toilets are raised at the bowl level, we started by dismantling the toilet to make the floor flat. After dismantling the toilet, we will create a base for the floor and remodel it into a Western-style toilet. Replacing the Japanese-style toilet with a Western-style toilet makes it easier to use and looks like a new building, which is very popular.
