Still need to fit floor supports and a floor but a quick test shows that our Natures Head composting toilet fits in our stripped out aft head compartment with room for your feet with the door closed plus just enough headroom.
Plenty of space for a small basin, holding tank and storage for toiletries (probably none of that before we launch for next summer though).
In order to get afloat we won’t spend any time fitting a new headlining, instead it will get a few coats of white paint.
