i have a request to make a cake for a bachelor before his wedding.
they wanted a shower stall with a toilet in it, since this is what his bathroom looks like and its tiny. i was thinking to do a wall of tile with a showerhead and some knobs and the toilet right next to it. how would i do the tile wall?

I'm not very experienced, but I would cover cardboard or foam board with fondant and use an impression mat or ruler to make the tile squares and then handpaint each square to reflect the color of his tile. If it's all white, then no problem. Maybe brush piping gel over it to give it the glossy bathroom tile look.
