En suite Bathroom
Because of the proximity of the bedroom, noise is and issue. As most often bedrooms do not have any windows so an extractor fan with a timer is essential-in-line fans are very quiet. The noise of a toilet cistern refilling can be reduced by fitting a quiet , modern type float valve
Cloakrooms
Designs of sanitary bathroom fittings include space-saving considerations, ie. narrow "slimline" toilet cisterns and toilets and basins designed to fit into corners. A cloakrooms should have a window that opens or an eextractor fan.
Wet rooms
Wet rooms are bathrooms that include a shower with no enclosure-the waste water runs away through a drains in the floor. The whole bathroom including the walls and floor has to be fully waterproof. That is why employing local reliable approved tradesmen is an absolute necessity for superb finished work.
New bathroom considerations
Even if the sanitary fittings retain their original position, check that supply and drainage pipes don't need to be extended or modified. A new tiled floor will increase the floor height which have to be taken into account. Flexible sanitary connectors might be used to accommodate changes. The dimensions of new bathroom fittings have to be carefully checked to ensure compatibility with old pipe connections. Improvement of ventilation and installation of new bathroom fan might also be considered. Stud walls and old brick walls might need strengthening to accommodate wall-mounted or wall-hang washbasins or toilets. Floors would need strengthening if an installation of "retro" style cast-iron bath is being done. Professional opinion and advice of an approved reliable tradesmen should be sought.
Space considerations
All bathroom fittings require a space around them so that they can be used comfortably. For example, a bath should be at least 700 mm. (2ft 4in) from a wall or another sanitary fitting to allow user to step in and out , and dry him or herself easily. User should also make sure there is room for the door to open without scratching or chipping bathroom fittings. User should consider a space for a waste bin in planning. Make sure you fit items such as mirrors and vanity units where they suit the heights of all users when possible. Medicine cabinets should be lockable, and be out of the reach of children.
