The faucet 3 has a faucet 31 that extends inward of the sink body 11.

  According to the sink 1 for sinks of 1st Embodiment, there exist the following effects.

  (1) In the sink sink 1, a wide space is required on the back side BS from the relationship between the user's standing position and the convenience of work. Therefore, the first deck portion 5 is provided on the front wall portion 14 side in the bottom surface portion 13. Thereby, since accessories, such as detergent and sponge, can be arrange | positioned to the 1st deck part 5 provided in this side FS, a wide space can be ensured in the back | inner side BS of the sink 1 for sinks. Therefore, the convenience of the work by the user of the sink 100 can be improved while securing the space for arranging the detergent and sponge.

  (2) The first deck portion 5 is provided in the vicinity of the boundary portion between the front wall portion 14 and the pair of side wall portions 16. Thereby, a plurality of small items can be arranged on the first deck portion 5. Even if the user of the sink 100 is right-handed or left-handed, small items used by the dominant hand can be arranged on the first deck unit 5, so that the convenience of work by the user of the sink 100 can be further improved.

  (3) The height of the first deck portion 5 was formed to be 15% to 30% of the depth of the sink sink 1. Accordingly, when an accessory is placed on the first deck portion 5, the placed accessory is unlikely to exceed the upper end of the sink body 11, and is easy to fit inside the sink body 11. Therefore, the space around the sink body 11 can be widened. Moreover, it is easy for the user to work on the near side FS of the sink 100.

  (4) The sink body 11 was formed by integral molding with a synthetic resin member. Thereby, a deformation | transformation location like the 1st deck part 5 can be shape | molded easily.

  (5) The bottom surface portion 13 was gently inclined from the front wall portion 14 toward the back wall portion 15 side. Further, the bottom surface portion 13 was gently inclined from the pair of side wall portions 16 toward the drainage portion 18 side. Since the user of the sink 100 mainly cleans tableware and the like from the center of the bottom surface portion 13 on the back wall portion 15 side, the front side FS of the bottom surface portion 13 does not have much water. Further, since the bottom surface portion 13 is gently inclined toward the back wall portion 15 side, the water flowed from the faucet 3 is on the front wall portion 14 side, particularly, the front wall portion 14 provided with the first deck portion 5. It is difficult for water to reach the corner portion where the pair of side wall portions 16 intersect. Therefore, the detergent and sponge disposed on the first deck portion 5 can be hardly sanitized with water contaminated by rinsing or the like.
