I have a bathroom on my outside porch that isn't being used and hasn't been for a very long time. I would like to take the sink/toliet out and put my washer/dryer in there (they're currently in the garage that is detached) What expenses might incurr in doing this? Is it really really expensive..Thanks.

should be easy if you have water hookups in place and proper tools

it should be quite cheap if you do it yourself when you take out the toilet cover the soil pipe and and put an end cap over the water inlet pipe if your dryer needs a vent run outside then use one of the existing holes from the overflow just make them bigger using a bore you can use the cold and hot water pipes from your sink to feed your washing machine and the same waste pipe from the sink all you should have to buy is some connections which arnt expensive
