A small walk-in shower and wall-hung drawers share our Stonehaven bathroom with a vertical metro-tile strip at the mirror. The painted walls and vinyl floor give the strip a quieter background. Its width can be chosen to support the basin area as a whole, while respecting the size of the tiles used to build it.
Ask to compare the mirror and tile strip on a measured elevation. Show where the mirror ends and where a full tile or cut would sit at either side of the feature. Include the tap and basin centre so that the strip can be judged with all the fittings below it. Adjusting the tile run by a small amount can change the balance at both edges. It is the kind of detail that looks simple when the widths have been considered together.
