I am just about finished with a bathroom shower tiling project. I have tile going all the way up the walls, and an acrylic shower pan. I was told by a guy at Home Depot that you still have to use caulk in some areas. Is that true? Why? I thought that grout everywhere between the tiles and shower base was sufficient. Is caulking a practice that the tile professionals use even after all the grout is in place?

What is standard height (code or best practice) for electrical outlets above a counter? This is for a combined large kitchen and laundry room. On one wall (the kitchen wall) there is a long kitchen counter at a height of about 36" from the floor. On the opposite wall (the laundry wall) there is a standard front loading washing machine and dryer. The size of those front loading laundry machines meant that the counter height had to be placed at about 41 1/2" from the floor. I have placed all electrical outlets at about 43" from the floor. All the electrical outlets above the kitchen counter appear normal and at a good height from the counter. However, because the laundry counter is much higher off the ground than the kitchen counter, the electrical outlets above the laundry counter seem way to low. I measured and there is only about 1 1/2" of space between the top of the laundry counter to the bottom of the counter-top electrical outlet. Is the 1 1/2" gap above the counter between the laundry counter and electrical outlet sufficient? Or do the electrical outlets need to be raised?
