we consider the ideas that they may put forward. It may also mean that the

new-build installation, the order in which they are fitted might not be. In this
situation, the customer cannot be without a WC, especially if the one you are
replacing is the only one in the property. There are two choices in this situation:

1 Leave the existing WC in place until all other appliances have been fitted:
if the appliances are to be installed in the same positions as the original

be removed and any damage done to it while installing the bath will not
matter. If the new WC is fitted first, in this situation damage could be costly
in terms of materials and labour charges.
