I used this product to mount a wall mounted bath / shower mixer tap because it reduced the space required for fitting the bath tap on the wall. The wall was in a mobile home and did not have sufficient space to use the wall mounting kit supplied with the tap. Wall mounting was the best option as the bath could be fitted after tap was mounted. With the bath in position there would be no access to fit bath mounted taps without cutting open the outside wall. Pity the illustration on the website did not show a bath / shower mixer tap wall mounted with this kit. It works beautifully. Bath mounted taps are such a pain to get to.
