Washing machine, shower room question.

[richardrich79]

We are in the process of fitting a small (electric) shower/toilet in our old scullery. The ceiling has been removed and a large velux will go in the roof.
The plan is to terminate the new stud walls that will enclose the washroom at about 2.6m (the length of the plastic wall planks.
Outside the washroom but still in the scullery we want to have the washer & drier powered by a fused spur from outside the scullery in the kitchen.
Does this set-up sound feasible or is our electrician going to say no?
Building starts Monday but the plan for this part is still flexible.

Sounds OK.

This will be OK 2.25m is the magic figure which means it is or is not classed as another room.

If the laundry appliance are not within the shower room, then there would be no problems regarding the location. Whether the configuration of the circuit you are taking the spur from will allow you do do this without issue, is another thing all together.

Thanks for the replies. The washer and tumble drier are already wired into a fused spur from the kitchen so shouldn't be an issue & there is already an electric shower on the floor directly above which is being taken out so hopefully assuming the wire is the correct size he can simply extend it downward to the new shower.
Mind you nothing here is ever simple or straightforward

Electrically question answered, but you should consider air flow and condensation. The situation you're proposing will give hot wet air and cold surfaces linked via the top of the sub wall. I'd suggest stopping air movement between the two areas and maybe considering an extractor for the shower area.

As you say nothing simple/straight forward.
If you do extend the circuit, any joints made must be easily accessible for maintenance, inspection and testing.(unless maintenance free joints are made)
If the cable is buried within the fabric of the building, it must be installed in the permitted safe zones. There are also building regulations concerning the depths of chases in solid walls and the holing of joists.
Other issues would be 30mA RCD protection and any additional factors concerning installation method and voltage drop. (which would could increase the cable size required)

I shall be leaving the question of extending the shower cable and any joints etc to a qualifies sparks. Sods law however means that the consumer unit, which is modern, is situated underneath the 'new' bath room so it will be wise therefore to run any new cables now. Thankfully there is room and my thinking therefore is to run a new cable now that can handle a 10.5kw shower thereby avoiding any future problems and hopefully all he will have to do is attach both ends

 

[PrenticeBoyofDerry]

I would suggest installing a 10mm2 T&E cable then, remember you will also require a shower isolator switch.
If you have a combi bolier, it would be possible to install a thermostatic shower, rather than electrical shower.

Thanks, I was going to ask what size cable. We will have a thermostatic shower upstairs, hence the electric downstairs.
