I'm boring myself now. I decided to buy some cripplingly expensive beautiful tiles from Fired Earth to tile my bathroom and have paid through the nose for their sealant because I figured that if I used someone else's I would have no comeback if it discoloured the tiles or flaked or something. I have now talked to them about adhesive and grouting and apparently it is going to cost £££ - basically as much as the tiles cost! They're not going to fall off the walls if I use an alternative are they? Anyone got any horror or success stories they'd like to share?
