How to hide pipes in the bathroom

Recommendation points

Hidden pipe laying in the bathroom is the most difficult stage in the distribution of utilities. The main difficulties are associated with bathrooms and combined toilets – in kitchens, pipelines run behind furniture, and individual toilets are more compact and, as a rule, have fewer points of consumption.

Features of hidden laying for different water supply systems

The simplest and most common water supply system is the so-called “tee” scheme for distributing hot and cold water pipes to consumers. In it, one pipe departs from the riser, from which, with the help of tees, branches go to the connection points of stop valves: mixers and taps.

The advantage of such a system is the minimum pipe consumption, but there are much more disadvantages..

For the user, this is expressed in an unstable water pressure, depending on the number of simultaneously switched on consumers – “the more, the less”.

For hidden pipe laying, such a system imposes certain restrictions associated with the very fact of the presence of such a unit as a tee. Any detachable or non-detachable pipe-to-fitting connection poses a potential leakage hazard at this point (especially for steel pipes that are prone to corrosion).

It can be said unambiguously that brazed joints of copper and plastic pipes can be “hidden” in a wall, box or screed without restrictions.

In principle, the same recommendations are given for welded joints of steel pipes. But as practice shows, the weld is not so reliable:

  • firstly, high temperatures at which steel melts change its structure and properties (and not for the better);
  • secondly, in a limited space, it is quite difficult to make a uniform and durable seam along its entire length.

A threaded connection of a pipe and a fitting, if the winding is done correctly and with high quality, can be much more reliable and durable than a weld.

But in any case, to monitor the condition of welded and threaded joints, it is best to provide an inspection hatch in this place (especially since there are a lot of their varieties, including for facing with ceramic tiles).

Unlike the traditional one, the collector circuit of the water supply system has no restrictions on hidden wiring. In fact, it consists of “whole” pipe sections (from the distribution unit to the receiver) without taps and branches. But this scheme also has its drawbacks:

  • it is necessary to provide a place for arranging the collector cabinet;
  • it is necessary to lead its own line to each consumer connection point, which is not always possible purely technically.

Therefore, this scheme is practiced for private houses or large apartments where there are no problems with the size of the bathroom..

Hidden internal routing methods

The most economical (in terms of useful volume) method is to lay pipes in the wall. It can be in an already existing wall, or rather, in an interior partition.

Attention! Changing channels in the outer wall is not recommended for at least two reasons – deterioration of thermal insulation properties and influence on water temperature. In addition, the outer wall is often a load-bearing wall, and it is directly forbidden for them to slit horizontal channels..

For interior walls, concealed piping is also limited. And the point is not only that they can be load-bearing – even for self-supporting walls, the recess of a sufficiently large channel in the horizontal plane may not pass without leaving a trace. Therefore, it is necessary to consult and obtain permission to carry out such work (if only because, to some extent, this refers to the transfer and change of the engineering communications scheme).

In addition to “bricking” the pipes into the wall, they can be hidden in the screed. In principle, this method is practiced together with the previous one – the horizontal liner goes along the ceiling, and the vertical one goes along the wall (and even a reinforced concrete slab can be gouged here). Such a scheme is especially often practiced for collector wiring. In this case, you can lead the pipe along the shortest distance (but only if there is no “warm floor”).

In both cases, pipes are laid in special corrugations – they are designed to compensate for thermal expansion (especially important for hot water supply and heating).

Technologically, the simplest and most attractive way is to lay pipes behind a false wall or inside a plasterboard partition. As with any communications, pipes cannot be laid inside guides and rack profiles.

Even easier (but less aesthetically pleasing) is the use of boxes. In fact, there will be only one box in sight – the lower one, in which you can hide both water and drain pipes. Vertical piping to faucets or washing machine is almost invisible (especially to the bath or shower).

For concealed pipe routing, you can also use the interior space in bathroom furniture if it is installed without “gaps” between the riser and consumption points.

How to hide risers

Risers are much easier to hide. Often, for their laying, special niches and boxes are used, provided by the project. The main task is to install hatches when facing or decorating, the dimensions of which would allow you to freely use shut-off valves and water meters.

If there is no such box, then its construction is not very difficult. For this, all the same metal profiles are used, which are then sheathed with plasterboard or plastic panels. Alternatively, such a box can be made to order in the form of a cabinet made of the same materials as the rest of the furniture, and part of its volume can be used to store detergents and cleaning products..

When overhauling an existing apartment, in a new building, in a private house or cottage, you can hide the risers (as well as the water treatment system and the collector unit) behind a false wall or inside a plasterboard partition.
