How far can slab cold water inlet be from shower tap - 1200mm?

[K123456]

The hole in the slab for cold water shower tap inlet is 1200mm away from where it needs to be. Is this a problem?

The bathroom is on the second storey (concrete slab) and it looks like the builders may have put the plumbing for the shower inlet about 1200mm away from where it needs to be. Is this an issue or can horizontal plumbing be used to move it 1.2m?

The builders went into liquidation so we are trying to work out if a redesign is necessary before starting with new builders.

Cheers in advance for the help!

Where the toilet is the shower is going there hence two pipes at 152mm apart in guessing someone needs to have a word with the plumbers asap
