<P>PROBLEM TO BE SOLVED: To provide a bathtub waterproofing pan bathroom unit formed of foam plastic in which a water leak check can be made while preventing a bathroom unit from being compressed and deformed by a load of a bathtub and without providing any inspection hole on a bottom face part. <P>SOLUTION: A bathroom unit comprises a foam-molded bathtub waterproofing pan 300 disposed adjacently to a washing floor 100 without gap therewith and a bathtub on the bathtub waterproofing pan 300. In the bathtub waterproofing pan 300, a bottom face part 301 which receives a load of the bathtub and side wall parts 302b and 302d extending upward from around the bottom face part are formed. The bottom face part 301 is formed at a low foaming rate in order to prevent compression and deformation caused by the load of the bathtub and between the side wall parts 302, the side wall part 302d at a side of the washing floor is formed at a higher foaming rate than that of the bottom face part 301 in order to have flexibility. The side wall part 302d is pressed and deformed in a horizontal direction, thereby forming a space for confirming water leakage from a drain member disposed at a lower side of the washing floor 100 and the bathtub waterproofing pan 300. <P>COPYRIGHT: (C)2013,JPO&INPIT |
