Smell In Bathroom
A strange sewer smell in the bathroom can be a simple problem like a dry floor waste but often there is an underlying issue which will need to be looked at by a plumber.
Common problems can be broken seals on toilets, dry floor wastes, tree roots entering floor wastes and drains, or cracked pipework beneath the bathroom.
Blockages in downstream pipework can also cause an odour inside your bathroom or laundry.
Check individual drains for an odour or debris, a torch may help you identify anything that shouldn’t be down there.
