Hi, my plumber has just fitted my new bath and taps and plumbed in the pipework for the new mixer shower to the wall which he's yet to fit, however on close inspection I see that the pipework to the wall is not centrally aligned with the bath or the bath taps so the shower will be fitted off centre. My immediate instinct is that this is not right and he's measured incorrectly, please help, any feedback is greatly appreciated before I speak to him. He's also left me with two leaks under the bath which I will be speaking to him about anyway...thanks
