Here are some before and after shots of the guest bathroom that I redesigned for my clients. You'll notice the "before" shot shows very dark tiles in the shower stall, floor and laminate countertops. The bathroom was painted one of my favourite colours "Wickham Gray HC-171" by Benjamin Moore to lighten up the space. It has a nice light blue tint to it, yet it still manages to stay warm. The clients liked the tile I picked for their master bathroom so much we used it here as well on the flooring as well as on the bathtub surround.
Here's a comparison of the Before and After of the shower stall. Since this bathroom would be used mostly for bathing their kids, we installed a double shower head with a spray so they could be "hosed down". The wall tile is a 4" x 12" white glossy ceramic, with a black and gray marble 6" mosaic trim to tie into the new Ceasarstone countertops.
I totally love this quartz countertop. In person, it is a lot lighter, and is a beautiful slate gray.
