I would love a tumble dryer but our kitchen is too small. I think I have a few options. I could put it in outbuilding, under the stairs or in a spare room. At the moment my preference is under the stairs as it's closer! Would I need a condensor dryer? That means I would only need a plug right? No need to vent or anything, just empty out the water? How often do they need emptying and is this easy to do? Are they any good? Thank you all!! :)
