1. The thermostatic valve core can help maintain a preset water temperature to aviod sudden changes of temperature in shower.

2. The outlet temperature can be locked at 40°C to prevent accidental overheating or scalding by mistaken touch or use.

3. Three modes of outlet can be realized by one key on the hand-held shower head.

4. The lower water outlet is rotateable so that water can be discharged when it is rotated. When it is not in use, it can be rotated against the wall to save space and reduce collisions.
