Hi Dundrum16,

I have built wardrobes successfully in bathrooms. It all depends on your own habits and how it is ventilated. Mould and damp can grow in any room, especially when warm air meets cold surfaces mixed with little air movement. The ones in these, photos we turned into a utility, storing the washer & dryer as it was very low budget and we couldn't afford the mechanical ventilation and heating costs for what was required in order to maintain that kind of wardrobe that stored clothes. We put in a standard bathroom extract with a slightly longer over-run (seen in the second picture) and we never had any damp issues. But we ALWAYS opened the window the whole time the dryer was on and closed that sliding door into the room as the dryer wasn't vented externally (just into the room). We couldn't afford to keep the heating on the whole time and we actually were heating a lot less than the average family (around 1 hour in total a day intermittently - which isn't recommended!)

If what you want is basically a walk-in wardrobe in the bathroom this is totally possible! But again mechanical ventilation, heating and personal living habits will all play a part. Avoiding drastic temperature changes and ensuring moisture is under control is imperative, whilst also keeping an eye on and ensuring the cupboards don't get too full, plus ensuring the joinery is moisture resistant etc. Getting a specialist mechanical ventilation design will be what you need. It is not a "cheap" solution if that is what you are hoping for (unless you invest up front for low energy heat pumps / exchanges etc. - but a good M&E specialist will be able to work this out no problems).

I have to admit I wouldn't normally specify anything like this except for super luxurious properties as I know that there is a cost associated with ensuring this all works successfully. If this isn't something you can afford to maintain then don't go down that path unless, you opt for storing utility items as we did and ensured that everything was well ventilated and kept clean.

I hope that helped you make the right decision for your circumstances.

Have a great day.

Jo
