Planning to update our upstairs bathroom. It is our only bath on the second floor, about 5 x 6 feet plus the tub on opposite wall from sink. We have picked out tile, light in color and plan to take down the arch over the tub to allow more light and open up the space. Struggling with how to add storage. There is some storage on either side of large mirror right now. There is a large closet outside in the hall where I keep most things. I've seen photos on Houzz of countertops that extend from under the sink to behind the toilet, and then use a vessel sink. Perhaps put some storage under the sink? We like the idea of keeping things simple so it does not feel cramped. I will attach a photo of the current bathroom and the tiles we have picked out. Probably going to choose a medium to dark grey wall color. It was suggested that we put the square mosaic tile above the sink, covering the entire wall and only have a framed mirror and lights, no storage to keep it clean/simple.
