Convenience is enhanced if the surface layer sheet of this type of washroom floor panel can be reformed when damaged or deteriorated, or for remodeling. However, it is not easy to accurately position and install a new surface layer sheet with respect to the panel body at a bathroom remodeling site. Also, when replacing the drain port member, it is necessary to position the drain port member and the panel main body.
In view of such circumstances, the present invention makes it possible to easily position and install a surface layer sheet with respect to a panel body when remodeling a floor panel of a bathroom washing area, and preferably simplifies the replacement of the drain port member or eliminates the need to replace it completely. The purpose is to

In order to solve the above problems, the present invention provides a wash area floor panel provided in a bathroom wash area, comprising:
a panel body having a body drainage opening;
a surface layer sheet having a surface layer drainage opening overlapping with the main body drainage opening and covering the upper surface of the panel body;
a drain port member having a drain port;
The drainage port member includes a drainage base member having a main portion of the drainage port, and a drainage edge member having an upper end portion of the drainage port and separably joined to the upper end portion of the drainage base member,
the drainage base member is housed in the body drainage opening and joined to the panel body;
The drainage edge member is joined to the surface layer sheet along the edge of the surface layer drainage opening.

In the wash area floor panel, the drain member is divided into a drain base member and a drain edge member. As a result, for example, the following reform work can be performed.
At a renovation site, the old surface layer sheet is peeled off from the panel body and removed, and the drainage edge member is separated from the drainage base member and removed. Leave the drainage base member as it is.
A new drainage edge member is previously provided in the manufacturing factory or the like in the surface drainage opening of the new surface layer sheet. The new surface layer sheet is carried to the renovation site, and a new drainage edge member is joined to the left drainage base member. This positions the new surface sheet with respect to the drainage base member via the drainage edge member, which in turn positions it with respect to the panel body.

More preferably, the fitting projection is elastically fitted into the fitting recess.
The fit allows the drainage edge member to be positioned with respect to the drainage base member.

It is preferable that the fitting recess is filled with a filling sealing material.
When the drainage base member and the drainage edge member are fitted together, the fitting protrusion is buried in the filling sealing material. As a result, a liquid-tight seal can be achieved between the inner peripheral surface of the fitting concave portion and the fitting convex portion. As a result, it is possible to ensure watertightness between the drainage edge member and the drainage base member.

A separation tool insertion hole opening to the outer surface is formed in the drainage edge member,
It is preferable that the surface layer sheet is separably joined to the drainage edge member so as to cover the separation tool insertion hole.
By covering the separation tool insertion hole with the surface layer sheet, it is possible to prevent foreign matter from entering the separation tool insertion hole.
At the time of renovation, the separation tool insertion hole appears by peeling off the surface layer sheet. By inserting a separation tool into the separation tool insertion hole and applying a separating force from the drainage base member to the drainage edge member, the drainage edge member can be easily separated and removed. During the separating operation, the separating tool can avoid damaging the outer surface of the drain port member, particularly the outer surface of the remaining drain base member.

A surface layer sealing material is provided between the surface layer sheet and the drainage edge member,
It is preferable that the opening of the separation tool insertion hole is closed by the surface layer sealing material.
The surface layer sealing material can ensure watertightness between the surface layer sheet and the drainage edge member, and can prevent water from entering the separation tool insertion hole.
The surface layer sealing material can be installed in advance between the surface layer sheet and the drainage edge member in a manufacturing factory or the like. Therefore, the sealing work at the time of renovation can be simplified.
