A bathroom is a room which gets a lot of use and due to the water, can get shabby looking quite quickly. Tile grout and silicon can stain and even get mouldy and fittings can get lime scale on them and so you may want to change it regularly in order to keep things looking clean. There are cleaning products that could work for this and if you have a tight budget, then this could be the only option for you.
If you are trying to improve the look of the fixtures when you are improving your bathroom then it is worth trying to find ones that will not attract the problems you are trying to avoid. For example, if your tile grout tends to get discoloured then use one that is not white. If you have a bigger budget then do not use tiles behind a shower but use a self-contained cubicle. This is just plastic and glass so there are no places where the mould can build up so easily. These are very expensive, but if they last a long time then can be a good investment.
It can be worth doing research in to the problems that you have encountered and how to get over them so that when you do get the bathroom remodelled, you know exactly what to do to avoid the same problems happening again.
It is also worth thinking about the colour of your fixtures. In the 1980’s coloured items were very much in fashion and it has now changed to white. It is worth thinking about the future and whether you want to use something that may go out of fashion or may not. Obviously it is down to your personal taste, but if you want to sell the house in the future then things like an out of fashion bathroom could affect how many people are interested in buying it.
