Abstract: According to one embodiment, a wet-area device includes a main part and a first layer. The first layer is provided on an outer surface of the main part. The main part includes a main part unevenness at a side of the outer surface of the main part. The main part unevenness includes a plurality of main part recesses and a plurality of main part protrusions. The first layer includes a first unevenness at a side of an outer surface of the first layer. The first unevenness includes a plurality of first recesses and a plurality of first protrusions. The first unevenness is arranged along the main part unevenness. An average height of the main part unevenness is less than an average length of the main part unevenness.

Abstract: According to one embodiment, a wet-area device includes a main part, a first layer, and a second layer. The first layer is provided on an outer surface of the main part. The second layer is provided on an outer surface of the first layer. A hardness of the second layer is greater than a hardness of the first layer. The first layer includes a first unevenness at a side of the outer surface of the first layer. The first unevenness includes a plurality of recesses and a plurality of protrusions. The second layer includes a second unevenness at a side of an outer surface of the second layer. The second unevenness includes a plurality of recesses and a plurality of protrusions. The second unevenness is arranged along the first unevenness. An average height of the first unevenness is less than an average length of the first unevenness.
