hi I would like to know if it can be mounted on the bath? what is the Grohe reference for this tap. regards. Brigitte

Birgitte - 1 year ago

Thanks for your question, Brigitte. Unfortunately, this is not suitable for mounting on a bath. However, the G1VAL02 is a thermostatic bath shower mixer, which can be used alongside your bath but is only suitable for wall mounting.
