Changing a bathroom suite is usually a costly enterprise and as such is not done frequently so it is essential to think carefully before you buy about the type of suite you want and whether it will stay looking modern in years to come.
Firstly, you will need to decide on the layout of the bathroom and whether you are going to keep the fittings where they are or change the layout. Do you want to retain a bath or replace it with a large shower cubicle, or do you want to install Jack and Jill washbasins? These choices are down to personal preference but can be detrimental if at a later date you want to sell the property so keep this in mind.
It is a good idea at the planning stage to try to incorporate storage space in the bathroom for towels and toiletries. This could be by building a tall cupboard as adequate storage is a big advantage in a family bathroom.
Once you are sure about the fixtures you want in the bathroom look at the bathroom suites that are available in your price bracket. Some online deals may look cheaper but be careful as some of these are continental and use non-standard plumbing fittings so can cost more in the long run.
