Home amendment project? I have a bathroom on my outside porch that isn't one used...

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

Thanks.
Krono floors?
Answers:    it should be relatively cheap if you do it yourself when you take out the toilet cover the soil pipe and and put an closing cap over the sea inlet pipe if your dryer needs a vent run outside afterwards use one of the existing holes from the overflow just craft them bigger using a bore you can use the cold and hot water pipes from your sink to nurture your washing gadget and the same leftovers pipe from the sink all you should own to buy is some connections which arnt expensive
Gas fireplace flame does not budge large ample?
should be easy if you own water hookups within place and proper tools
