It is entirely possible to do >bathroom renovations cheaply as long as you are clever in what you do in order to completely change how the room looks. There are several things that you can do right now even if you are on the tightest of budgets and some of the easiest jobs are mentioned below.
First, look at changing the accessories in the room and this does mean changing what is used to dress the window and those small fixtures and fittings such as the towel rail, soap holder, and anything else that is basically screwed to the wall. By just changing these small fittings to something completely different, for example if you had white fittings you may wish to change to chrome, you can really alter the way that the room looks and as long as you shop around you should be able to get these fixtures for next to nothing.
Next, rather than simply replacing the bath and sink, which is expensive, do think about just having them refurbished in order to get their sparkle back and have them looking brand new. This costs you an absolute fraction compared to replacing everything because at least then you do not have to worry about pipes being installed or hiring a plumber for a full day and this alone is going to save you a small fortune.
Apart from the items in the bathroom you should also look at the walls and floor and it is a simple enough task to just go and paint the walls a different color and also change the floor to something new. These are the kinds of jobs that you can easily do in a day even with limited do it yourself knowledge, but by doing them you are going to completely freshen up the entire room and people are going to notice that there is something different about it from the last time they visited.
Finally, a lot of people will have tiles of some description in their bathroom and rather than replacing them you may prefer to simply freshen up the grout and even consider getting special stickers to change the pattern of the tiles into something new. There is also the option of getting special tile paint, but this is going to mean you have to mark off a lot of the tiles to get it looking neat and tidy and this is certainly going to just drive you insane and it is best if it is avoided.
Bathroom renovations do not have to cost you a fortune and the ideas mentioned above are just some of the things that you can do to ultimately change how that room looks. Clearly with each option there will be more expensive types of flooring or paint or accessories to choose from, but even if your money is limited you should still be able to get budget options that will look good at least for a reasonable length of time before you need to go through the entire process again.
