Ah, the joys of having a garden to your house!
When I had my bathroom refitted (an affair that took quite a long time, say months, although most of this time I could use the toilet) I quickly learned to have a spade with a roll of tp on the handle ready at all times at the door to the garden. I never knew when I'd suddenly find my toilet bowl in the hallway or the garden when I needed it. Even when the toilet was in it's usual place I never knew when the guy who was doing my bathroom would come in while I was 'doing my thing', merrily commenting on the smell and proceeding with his work unhampered by me
It really is remarkable what kind of stuff you can get used to!
If you ever need to resort to the garden with your spade for longer than a week or so I can advise you to have a system to remember where you have been already...
