Bathroom appliance help please

Hi guys just after a bit of advice here please

Customer wants to build a full height cupboard and the bottom of the bath and put a washing machine and tumble dryer in it. It will have a door on the cupboard.

How would regs apply to this ? I can make it 3 x flex outlets and sfs outside the bathroom if need be rather than sockets.

The appliances would technically be within 600mm from the edge of the bath but inside a cupboard so couldn't remember if that then meant zones did not apply 

Thank you for any help here

  • My "Dampness Chart" for all the relative humidity meter lovers (those cheap & easy RH /Temperature sensing for the damp house).

    100%RH is, obviously(?), the dew point for the lines of constant absolute water vapour.Dampness Chart

    The chart is also helpful for explaining why/how underfloor ventilation dries a house.

  • I rather doubt that there is a significantly greater environmental risk when "kitchen appliances" are situated in a bathroom.

    The biggest risks are 'mindsets', where folks don't understand/appreciate why/how different approaches are taken, and will switch off fans immediately they exit the bathroom and close the doors (just like they switch off radiators when exiting a room and leaving it empty).

    The shift from warm jumpers (scarves & coats), to warm room, to whole house shirt sleeve environment causes lots of confusions and old habits die hard. Frustrating for all!

    I blame double glazing, especially the period when it was hopper windows and no vents!

  • Answers on a post card !

    As long as the cold damp air isn't mist & drizzle (actual water aerosol or droplets) it'll be even better than you expect.

    Cold air contains very little physical water per m3, so adding a little heat makes the warm air very dry which dries the clothes easily (like on a line on a spring day). 

    Adding a dehumidifier tent to the garage also works well, especially if you can fix a simple drain point/tube to beast.

    It feels really un-natural to have "cold damp air" being the best.. - see all the folks with rotten sub-flooring because they blocked their air vents - those 'Air Changes per Hour' (ACH) have to match up to the human generated humid air generation/extraction!

  • I'm not too surprised - the aftershocks of lockdown and the attitude to working at work vs working at home has completely altered the pace of many kinds of engineering work, and not always positively.
    I find it is now surprisingly difficult to get a large group (well actually anything much more than 3) of people round a drawing pack on a table at the same time - which would be far faster then each one reviewing it off-line and throwing in conflicting suggestions that then have to be argued and traded off.

  • I don't think a condenser or heat pump dryer would work very well at all in the detached garage in winter.

    Heat pump possibly not, but I do not see why a condensing type would be affected. The condenser recovers some of the latent heat of evaporation to warm the incoming cold air.

  • I agree.  There are many a time I need to book an appointment slot in the company calandar to speak to someone.  I am a maverick so sometimes I just pick up the phone and call them.  lol
