DO IT YOURSELF
Since the middle of the last century DIY has been on the increase. Men & Women have been doing jobs-around-the-house themselves, rather than get a qualified tradesman to do them. It would certainly save money, depending on how good you are at it.
I'm sure, if you take a job on, you probably know what you're doing and if you're not sure there's plenty of books on the subject. There's also advice from the stores selling DIY items. Just be aware of the various safety aspects.
You can also buy complete bathroom suits and kitchens if you're so inclined. You won't be disappointed if you look at our merchants.
