The mosaic tiles are shades of blue, turquoise & green (very dark when daylight isn't on them). Tiling is full height on walls beside & behind bath & half-height on the 3 walks beside loo & vanity. Other bits are just plaster. Floor is nearly-black slate-effect vinyl.
(Bathroom is also laundry room hence oven gloves drying on radiator & pile of baskets 
)
I would quite like to go with a strong peacock-blue sort of colour but it might be a bit gloomy?
