(8) A bathroom unit comprising the waterproof pan according to any one of (1) to (7)

According to the present invention, since there is a step in the washing scene, there is no groove (dent) that becomes a hindrance to the drainage gradient, water and dirt are difficult to accumulate, the step portion becomes non-slip, and safety can be reduced. Absent.
In addition, when a plurality of steps are provided, the difference in height is dispersed, so that the user feels less uncomfortable when walking and there are fewer obstacles when using the wheelchair.
Conventionally, a joint is a joint that can be formed when stones or tiles are pasted on a floor, a wall, or the like, and a step having a joint can reduce the equivalent of an extra joint.
When the washing scene between steps has a plurality of grooves parallel to the drainage gradient, the flow resistance of the drainage can be reduced, and smoother drainage can be performed.
The groove is equal to or lower than the highest position of the height difference between the groove and the lowest position of the stepped portion with the washing scene upstream of the washing scene with the groove, and the lowest position of the groove is If it is more than the lowest position of the step portion with respect to the washing scene downstream of the groove washing scene, the drainage flow resistance can be further reduced, and the drainage time can be shortened.
Since the bathroom unit described in the present invention is not easily soiled, it can reduce the labor required for cleaning and does not impair safety.

  The drainage outlet described in the present invention allows the wastewater generated at the washing place to flow in, and its shape and size are not particularly limited. It is preferable to provide it at the side where the drainage water channel can be shortened, and it is preferable to provide it at the center of the side or at the end farthest from the bathroom entrance in consideration of water tightness.

  The drainage groove described in the present invention is for smoothly flowing the wastewater generated at the washing place into the drainage port, and the shape size is not particularly limited. The drainage gradient may be the same as the washing scene, but it is not the part where the user puts the legs directly, so the gradient can be tightened to improve drainage efficiency. In addition, by increasing the width and depth of the groove, when a large amount of water flows in at once, the water overflowing from the drainage port can be temporarily stored without flowing back to the washing scene.

  The washing scene described in the present invention has a one-sided gradient washing scene, and the shape of the washing scene is not particularly limited, but can be used without slipping when the user is washing the body, and It is desirable that there are irregularities on the back that do not feel uncomfortable. The washing scene used in the present invention is a collection of minute grooves with directionality, and these grooves are arranged so as to be parallel to the drainage gradient so that water flows smoothly.

  The level difference described in the present invention is a level difference that can be formed at the seam between the water-side washing scene and the water-side washing scene. With this level difference, water and dirt remaining during drainage can be reduced. Although there is no restriction | limiting in particular about the level difference of this level | step difference, It is preferable that it is a level | step difference which a user can use without discomfort.
