hi all, my kitchen ceiling is stained yellow from the leaks in the bathrom, there is a big wet patch which looks like it is directly under the bath, then another directly under the toilet and the again with the sink. i have re siliconed the outlines and still is happening i had a plumber in to look at it and he just said get your husband totake up the floorboads and find the leak, i have had the bath panel off but everthing is bone dry. any advice please, many thanks jules09

Do the waste pipes go under the floorboards ? leak from waste ?

Also worth check for cracks in the bottom of the toilet bowl.

The plumber is right though - either lift floor boards or cut out a section of plasterboard from the kitchen ceiling to find the leak. There's no other way.

If the ceiling is wet but the floor (when you remove the panel) is dry then it MUST be under the floor. You'll have to take some boards up.

Cheers
