Mixer shower units

[AJR48]

I have a Mira mixer unit. The flow cartridge is faulty making the tap difficult to turn on. I sent for a replacement cartridge but was unable to remove the exisiting one as it was seized up and the depth of the part where the spanner fits is very narrow causing the spanner to slip off. Even after applying WD40 I could not budge it. The cost of sending for an engineer makes the exercise not worth while so I have decided to get a whole new mixer unit.

My question is this: Is the distance between the hot and cold inlets a "standard" measurement? i.e. if I buy a none Mira unit will it fit?

Usually yes, there are exceptions though.

measure your centres. usual is 150 mm apart.

Thanks guys. I measured it as 150mm. Mira say it's 153mm. In any case I've found a Triton replacement that shows 150mm +/- 20 so I've ordered that.
