When choosing a leading colour to the bathroom, we fall into a vortex of ideas that sometimes we succeed and the effect is as expected, but more often after the renovation, we wonder what we could have done differently. When we look for inspiration on the internet, catalogues, stores and find something that has impressed us, we want to introduce it to our home and make our bathroom the same. There are several reasons for not reflecting the vision of our new bathroom, but we will focus on those that require a lot of effort and costs associated with removing them later. We can not always buy the same furniture, devices, or choose the colours of paints and tiles that we found in the catalogue. Another obstacle in the implementation of the plan is the location of the equipment as well as the size of the room. If we are doing renovation, it is rare that we change the place of the toilet, sink or shower. Rather, we replace them with newer devices, but they are still in the same place, because most often we do not have the possibility to change.
