Hello, I am new to this site and seeking some advice on the tiling in our new bathroom. We are really unhappy with the quality of the tiling and have voiced our concerns to the plumber (he also did the tiling). He says he did the best job he could and blamed wonky walls and a difference between the thickness of the wall tile and mosaic border for the defects (the walls were re-plastered prior to him tiling by a plasterer he chose, he sub-contracted the work out). He believes he has done a good job and cannot understand why we are not satisfied. Surprisingly he said he would be willing for us to deduct the cost of having the issues rectified by a tiler of our choice and he will also agree to us deducting the cost of replacing tiles from his invoice. It was agreed that we would pay on completion so we haven't paid anything yet as the job isn't finished. We have since had 2 different tilers come and take a look and both have suggested that all the tiling needs to come off and the bathroom suite will need to come out beforehand to prevent damage. Depending on the condition of the walls underneath the walls may need plastering again and then the bathroom suite would need reinstalling. So basically it would be like starting over again. I have told the original plumber what the 2 tilers have said and he says that they are probably just saying that to get extra work. He is now asking for part payment to cover the cost of materials and the labour for the work he sub-contracted out and we don't know what to do as the quotes we've had to rectify everything are around the same as the total amount he is requesting! I have tried to attach some photos of some of the issues (there are so many!) but I can't figure out how to do it! I've added 2 pics under Poor workmanship? I don't know whether you will be able to see them? I would be so grateful for any advice you can offer me. Believe me, I don't like complaining and I am truly devastated it has come to this but I stand to lose a lot of money if I pay him and do require the whole lot doing again. He is not willing to put right his own defects either so we're stuck!
