We are wanting a tile splashback in our kitchen. The tiles we are wanting to use are 300mm x 900mm and would be horizontal, at one high, with the exception of above the oven, where we would have it 3 high. It is needing 6 tiles, which we will provide. 2 tiles would need to be cut to fit the space - just the ends trimmed. We assume one tile would cover these 2 spaces. There are 3 power points to be cut into the tiles as well. We are looking for a quote/estimate on how much this job will cost. Also we are wondering whether we need to have spare tiles.
