Why the bathroom, you ask? For one, I feel like it's the optimal spot, especially if you have future plans to install any type of 'green' appliance out there that recycles water from the shower and sink. We've been interested in investing in a concept like that for a while now, but most seem to require a great investment in infrastructure work - something that many of us don't have access to. However, even if you plan on installing just a regular washer and dryer, the bathroom is great because appliances are already tried and tested in a humid environment. However, it is probably a good idea to check for mold every few months, just in case.
The alternative is to invest in a washer that combines itself with a sink. Smeg makes a pretty sweet one and it comes in a variety of colors much like their refrigerator line. Do you have experience with a washer and dryer in your bathroom? Let us know the perks and drawbacks of such a setup?
