My downstairs neighbour likes to cook but the smell comes up and through our bathroom floor and it stinks our whole house out. Our bathroom floor is tiled but there are gaps around the pipes which I'm not sure how to seal. Normal air fresheners don't work at all and I was wondering if there is any odour absorbing fabric/insulation we could put around the pipes to stop the smell?

If there's no kitchen exhaust fan the offer to install one. Go to the source of then smell and vent it outside. Good luck, Tom
