lt may be, though, that what you have in mind, indeed what your existing bathroom cabinets desperately needs, is some radical alteration, perhaps involving entirely new equipment. This is when you will want to investigate the existing plumbing and pipe runs in order to assess the possibilities. Anything is possible. It existing water pipes enter the room at one side but you would like to move the bath and wash bowl to the other, you can do so by running the pipes under the floor to emerge in their new position, provided you arrange an adequate drop to ensure the easy flow of water. But it will take time and cost money, so weigh up the merits of such a job first.
Likewise, the soiI-pipe for the lavatory which will probably be connected to an outside wall will be expensive to move more than a short distance. What you can do perfectly feasibly – in addition to course to replacing obsolete or ugly sanitaryware is to move things within the range of the existing plumbing outlets so that the whole room functions that much better. For instance, a bath running along one wall which has a door in it may be very much more comfortable to use running along another which doesn’t – and it can be moved with very little extension ot the water pipes, as shown. Or it may be that a washbasin is set in just the position on a wall which precludes it being built into a vanity unit because of a door opening, whereas moving it iust two feet along would get rid of this obstacle, as shown.
Minor but vital alterations of this nature can make a considerable difference to the comfort of a room.
