To do this, the tools you will require are a drill and suitable drill bits, an adjustable pipe wrench, and an adjustable spanner which you will need to use to unscrew the taps and waste outlets. You will need to unscrew the screws that are holding the basin to the wall and if brackets are used to hold the bath up against the wall, these can be removed with a hammer and chisel.

You then need to prepare to install the new basin and bath. Firstly you can fit the taps but it is important to ensure that they are at 90 degrees to the inner rim of the basin and are positioned equally. You will then need to fit the flexible tap hoses. These should be affixed to the tap tails which you can see slotted through the tap hole once your taps have been fitted.

In order to secure the basin and pedestal you will need to drill holes in the floor for the floor fixing screws and in the wall for basin screws. Ensure if you are fitting the basin to a tiled surface that you take care not to damage your tiles, and if in doubt, consult an expert. Put the pedestal in place and secure it, but before screwing it to the wall fully, ensure the basin is level. If you are satisfied that it is level, tighten the screws and use silicone to seal round the pedestal, trimming off any excess to leave a neat finish.

Assuming your bath is being positioned along a wall, fixing the bath into place will require drilling holes for the wall fixing brackets, and if your taps are not going to be in the same place, you may need to adjust the waste and water pipes. Ensuring that the bath is level, and having attached your bath feet if the bath is open rather than concealed behind a panel, attach the taps and the flexihoses, position the bath and inject silicone between the bath and the wall to provide a waterproof seal, then screw the fixing brackets to the wall and the feet to the floor.

After this you will need to connect the flexible tap connectors to the water pipes, taking care to ensure that there are no twists or kinks in the hoses. When all is complete, turn the mains water supply back on to check for any leaks.

If you know where your new bathroom will be located, the next step for you is to work out your budget for building your bathroom and purchasing materials such as wall coverings, bathroom suite, flooring and bathroom accessories. Whenever you are adding an extra bathroom I would always use new fixtures this will add value to your home and give you a more modern effect, and there are often good offers in DIY stores or plumbers merchants.

As long as there is no building work to be done, once you have chosen your bathroom suite and have your bathroom design sorted, you can fit your new suite. Make sure your water is turned at the stop cock and run the hot and cold taps to remove any water still in the pipes and flush the toilet to empty the cistern. You can then install your toilet, sink, bath and/or shower. If you are fitting a bath that you will be able to see under or behind, such as a roll top bath or a bath that goes against the wall but does not have a bath panel, you should tile the floor and around areas that will be inaccessible once the bath is fitted before you install the bath itself. You can then continue tiling above and around the bath after the bath has been installed.

A good tip if you have chosen an interior room for the location of your extra bathroom or WC is to put in an extractor fan to remove moisture from steam and condensation stopping the walls from getting damp. This should then stop any mould or mildew appearing.

The next part is really all down to yourself and how you want to decorate your new bathroom e.g. all your painting and tiling. Your choice of wall and flooring materials will obviously will depend on your budget and how much you have allowed for this, but one major thing to keep in mind when you are deciding on your budget is that unless you are planning to do the work yourself, you will need to bear labour costs in mind, and this can often cost as much as your bathroom suite and tiles put together.
