If you go into build mode, then choose "by room" and select kitchen, on the left on the picture of the kitchen that you can click on to choose fridge, counters etc, there is a thing on the bottom right that says "auto counters on". If you change that to off, then when you select the type of counter you want, when you click to expand the colour choices, the different counter options will come up, too, like rounded end counters, middle pieces to make an island etc.
