I have a job to go and look at, very posh lady (sounded posh anyway) much like your job she told me it's only 3sq mtrs. I said is it a splashback, no it's between a bathroom and an en-suite she said. Another tiler has done most of the work and it is just the awkward bits left, it will only take you about half a day she said, as that's what the tiler told her. I asked why he didn't finish and he she told me he felt ill. There is no way i am going to finish it but i am going to go and have a look, just to be nosey. i will try and take some pics if she leaves me alone.
