All new building works must comply with the Building Regulations. New wiring is often required, together with a fuse protected by RCD device. Electrical ventilation in bathrooms is also required. The cost of adding an ensuite can be determined by the type of property also.
Location of the new ensuite bathroom
The minimum space required for a bathroom is around 1.8 meters by 90 cm. Shower cubical, wash basin, WC, toilet.
Marking the location of the new ensuite bathroom, using masking tape of the floor.
The location of the new ensuite bathroom is normally in a corner of the room, using two existing walls, but it can also be affected by the location of the drains and waste plumbing. By using a macerator, an electrically powered macerator fitted with a pump – can send the waste down a flexible pipe to a sewage outlet, giving more freedom when choosing the location of the bathroom, by ignoring the layout of the joist works. However, our bathroom builders will always try to use a conventional and traditional waste and drains system, as marcerators and pumps, can often break down , depending on how often is used. We normally use marcerators made by Saniflo.

Waste, soil pipes and drains
Traditional soil pipes and drains, always works best, however, sometimes the floor joist works, can be a problem and compromising is the only solution in order to avoid expensive and extensive building works.
Building new walls. Existing joist work running in the opposite direction of the waste/sewage outlet.
In some cases, the soil pipes can be run under the floor joist works.

It is very important that the soil pipes are boxed in, not only for aesthetics, but also to avoid hearing the water and waste travelling through the soil pipe. Insulation, plasterboard and plastering normally will suffice. Lights can be used inside the boxed pipe to use the box as a feature in the room below.

Walls and doors
The walls can be built using timber, as small as 47mm by 47mm, in order to use the minimum of space.The frame is then drylined with plasterboard,the cavity filled with acoustic insulation for sound proofing.Interior of the walls can be dry lined using water proof plasterboard, plywood or similar materials, where the tiling can be applied directly and no plastering/skimming is required.
The ensuite bathroom walls
Constructing the studwork for the ensuite bathroom is normally done to complement the bedroom or room, matching the walls, skirting boards, coving, doors and other features.

Showers, wash basins and WC/toilets
The minimum recommended showers tray size is 700mm by 700mm. The hot water can be provided by an electric shower or connected directly to the main boiler (recommended). However, if the water pressure is not high enough, a water pump might be needed. An electric shower must have its own fuse and electric cable.
