Our ensuite is 1/2 tiled exceot where quadrant shower sits. this is tiled to ceiling. Have a split shower tray and water leakage so need to dismantle shower and remove tray probably resulting in broken tiles at bottom. I dont want to retile whole bathroom but need to retile/replace tiles in shower area. Plumber has suggested the wet boards but I am unsure how to do this or how to retike without it looking mismatched/odd. Do i go for a contrast or something that blends in? tiles are currently palest grey with a few having embossed pattern
