would it be weird to have a bath filler with small hand shower on the bath and then also have a concealed shower control and shower head above? I can't get my head around using the concealed shower unit as a bath filler as wouldn't that be annoying when you're trying to top up your bath and its half way up the wall? Or alternatively if you have it low down won't it be annoying leaning down to adjust the shower temperature? Or have I just totally lost my marbles over my extension!!
