It is tempting to save some money by doing the work yourself. This is a good idea so long as you remain aware of your limitations, or you could cause some expensive damage. The last thing you need is having to pay out for avoidable mistakes.
Your budget will stretch further if you are willing to make some reasonable compromises. Choose standard bathroom and kitchen units but fit more expensive handles and taps, so spending less to create maximum impact. The more thorough your planning, the more likely your renovation will come in under budget and achieve all that you wished.
