2. Description of the Related Art Conventionally, a bathroom is provided with a bathtub in a small room and a bathroom floor, walls, etc., but recently, as described in Japanese Utility Model Publication No. 1-14744, a bathtub, a bathroom floor, and a wall are provided. It is widely practiced to manufacture a bathroom unit composed of the above in a factory, transport it to a construction site, and assemble and install the bathroom unit in a small room because the actual construction is small and the construction period is short. However, in recent years, the number of elderly people has increased, and many facilities in the house have been renovated for the elderly. When renovating a bathroom, handrails are often attached to the side walls for the safety of the elderly because they are slippery. The handrail mounting method of attaching a handrail to the bathroom unit is that when a new bathroom unit is installed, plywood, a piece of wood or iron material is attached to the back surface of the side wall surface of the bathroom unit before the handrail is to be installed before the bathroom unit is installed. The members were joined to reinforce the wall, and a handrail was attached to the attachment member from above the side wall surface of the bathroom unit. On the other hand, in the case of the existing handrail, the mounting member cannot be joined to the back surface of the wall at the handrail mounting position, so that it was practically difficult to mount the handrail. When attaching handrails without stopping,
A reinforcing material was stuck on the surface of the wall of the bathroom unit where the handrail was to be attached, and the handrail was attached.

[0003]

However, in the above-mentioned construction method in which a reinforcing material is attached to the surface of a bathroom unit wall and a handrail is attached, the reinforcing material is visible on the wall surface and significantly impairs the appearance of the bathroom unit. At the same time, since the reinforcing member protrudes from the surface, there is a problem that it becomes an obstacle.
Providing a handrail on an existing wall in this way is not limited to a bathroom unit, and in other cases, for example, when a handrail is attached to an existing toilet or the like, a similar problem occurs.

Accordingly, an object of the present invention is to provide a handrail mounting structure and a handrail mounting method that do not significantly impair the appearance when a handrail is provided on an existing wall of a bathroom unit or the like, and that does not hinder the reinforcing material. It is.
