En-suite bathroom

I will be installing an en-suite bathroom from scratch sometime in the next

4 weeks.

I have already successfully installed a new downstairs cloakroom wc and replaced an old bathroom suite, so I have a good understanding of most of the work to come,

We have a new combi boiler (which I also installed myself some 12 mths ago), which means I'll be installing a thermostatic mixer shower, wc and basin.

There is also a soil pipe directly outside the location, so no problems there.

The question/s are:

are there any "obscure" building regs regarding ensuites. I will be notifying building control, but it would be nice to know beforehand what special measures, if any, I need to take beforehand.

Obvious ones which spring to mind, are electrics to be checked by Part P person, suitably powerful extractor fan, equipotential bonding, correct type of waste connections to existing soil pipe. I will be using standard

63x36mm stud, which will run on top of an existing joist, the stud will contain fireproof Rockwool insulation, and I'll be covering in 2 layers of plasterboard, then skimming either side. Anything else I should be thinking about, is the stuff about the stud work correct?

TIA

No, because new electrics will be covered by your building regs application. The council will check them for themselves if they want to (and at their expense).

possibly with a run-on timer.

Yes, and also the zone requirements for luminaires and the fan. In a small en-suite you may find it easier to use low voltage lights and fan.

2 layers of PB (on each side?) sounds right; IIRC toilets need a certain level of sound attenuation to prevent plop-plots being heard elsewhere in the house.

They *should* check at their expense, but are highly likely to hit you with an extra fee for electrical checks: allegedly they will cave on this if challenged?!

They may want ot see sums to prove the joist carrying the stud wall is up to it. The two layers of PB on the wall are not actually required by building regs AIUI (although as Owain said deireable for other reasons!) since there are no special fire regs that apply.

The wall will only be 6 foot long, the first 3 foot will be on 1 joist, then a 90degrees join onto the next joist and then another 3 foot run.A bit like this: ____¦------

So we are talking very light loads.

10mm gap under door to en-suite to allow airflow (else it will be sucking air out and not replacing it at an adequate rate). This was picked up on a recent project of ours (that and a run-on extractor). The BC guy also wanted a roddable toilet pipe (roddable from inside and outside!) which was a royal pain to fit!!!

Thanks ST, would never have thought about the 10mm gap under the door. Do you know whether you have to have a door ,as there's going to be a sort of anti-room sperating the en-suite from the bedroom, so therefore we don't really need a door.

Also where did you get the roddable toilet pipe? It may be wise to install one, just incase the mother-in-law stays.
