Today we’ll discuss the necessary plumbing infrastructure for bathrooms, after the bathroom layout has been approved, including the placement of fixtures according to our needs and the intended use of each bathroom. Our requirements for bedroom bathrooms differ completely from those for guest bathrooms and other types.
Essential features in bedroom bathrooms include a sink, a shower, and a Western-style toilet; there are also additional fixtures such as a jacuzzi, a bathtub, bidets, and so on. As for guest bathrooms, the requirements usually do not go beyond a toilet and a sink.
As for toilet seats, there are various types, some of which require special installation, such as wall-hung toilets, where the concealed siphon is installed in the wall during this stage. The same applies to wall-hung bidets. and faucets—whether for showers, bidets, or sinks—are available in several types, some of which are installed during this stage and are called "concealed faucets," as are wall-mounted sinks, which require special installation depending on the model.
Before the plumber begins the demolition work required for the plumbing installations, it is advisable to visit retail outlets specializing in plumbing fixtures to review and examine all models and designs and determine what you need, so that the plumber can perform the necessary installation based on the specific measurements for each piece, We obtain the most precise measurements from the retailers. It is important to ensure that high-quality materials are used, especially for the concealed fixtures that are installed before the plastering work begins, Some retailers prepare a detailed plan with the required measurements for all plumbing fixtures, faucets, and other items. If you have an interior designer, it’s a good idea to have them review this plan before construction begins.
The building’s water heating system must be determined, and the choice of water heaters should be decided in advance. There are two options: first, a separate water heater for each bathroom or kitchen; second, a central water heater that supplies more than one bathroom or kitchen at the same time. If you wish to install a solar water heater, this requires setting up the infrastructure for a central water heater first, and then installing the solar water heater at the highest point of the building (the roof). Instant water heaters are available that heat water immediately; they are compact, take up little space, and are typically installed inside the sink cabinet. This type of heater can be used in bathrooms with limited use, such as guest bathrooms or washrooms, and requires a dedicated electrical connection.
A central water heater provides hot water immediately upon turning on the faucet, as hot water continuously circulates from the central water heater to all bathrooms via a special pump, in large quantities unlike a standalone water heater, In addition, the central water heater is located outside the building on the roof, unlike a standalone water heater, which is typically installed inside the bathrooms. A drawback of the central water heater is that if it malfunctions, all connected bathrooms will be without hot water until the heater is repaired. In terms of financial costs, the cost of a central water heater is approximately 60% higher than that of a standalone water heater, including materials and labor costs.
