surface wiring a shower?

[res1492]

Basically i want to put a shower in my Ex's bathroom for her and the son, it has already been fitted with a pull cord ceiling switch by an electrician so all it needs is power/water running to the shower.
The plumbing is sorted but my problem is the wiring, the wall that i want to place the shower on is tiled and i dont want to have to remove and replace the tiles to chase in the wiring as i tiled it myself last year , i was thinking/hoping that i could go up through the ceiling over the room and down the surface of wall that the shower is to be fitted on...is there a shower that i can wired in with surface wiring with "U" drip or do they all have to be wired from the back?

Is this something that i should be tackling myself or do i need to get a Qualified electrician to do the wiring?

Thanks in advance

There are a million reasons why you should get a spark back to finish the job properly.

But in theory can a shower be surface wired?
Unfortunately i dont have the money to get an electrician in so i am going to have to do it myself
Even if i do get a sparkie in will he have to chase in the wiring?

Thanks for your replies

yes it can be surfaced wired, depending on other factors, but yes it can.

in mini trunking and seal cable entry with silicon. be advised that, as it is in a bathroom, irrespective of surface mounting the cable, it must be protected by a 30mA RCD. if i were doing the job, i would remove relevant tiles and re-fix after sinking cable. might have to buy a tile or 2 though.
