Washbasin in the garage: 9 tips for choosing and installing

8 min

A garage for car enthusiasts is almost a holy place in which they spend a lot of time. There is the maintenance and repair of a car, motorcycle, bicycle. After almost any interaction with technology, you should at least wash your hands. Washing in a bucket or simply pouring from a bottle is not the most comfortable option. So it is worth taking care of various elements of the garage and arranging it with a convenient plumbing fixture, including. In this article, we have tried to consider all the important characteristics of the washbasin, so that it is easier for you to choose the right one.


Let’s take a look at what washbasins are used for the garage. They are divided into two types:

Sold in hardware, plumbing stores. They have different designs. Depending on the complexity of the device, the quality of materials, the novelty of the design and the fame of the manufacturer, the price changes.

Here fantasy can roam. You can make this device with your own hands from almost anything.

The finished sink can be connected to a homemade waste system. Pipes for drainage of liquid can be taken out of the garage for a considerable distance. More comfortable to use is a standard sink that can be connected to utilities. This is possible if the box has pipes for water discharge. In this case, it remains to buy the washbasin you like and install it according to the standard scheme, just like in an apartment or house.


Among the most popular materials for the execution of a washbasin for a garage, we note:

  • Stainless steel. Relatively inexpensive material. Items made from it are durable, easy to clean, and when deformed, as a rule, do not lose their basic properties. This option for a garage is one of the best.

  • Ceramics. Easy to clean and looks good. Due to the nature of the material, in some cases, you can break the shell or hit it so that a crack is formed. In this case, the life of the product can be significantly reduced, as well as deteriorate the appearance.

  • Plastic. The most budgetary option, easy to install and operate, but the most fragile and short-lived.

It is worth choosing based on the characteristics of the materials and the budget allocated for the purchase of the device.

The form

In shape, washbasins can be:

  • Rectangular.
  • Square.
  • Round.
  • Oval.
  • Non-standard.

You need to proceed from ease of use. For a garage, the best options are those that are simple and convenient, suitable for washing individual parts, and easy to clean / clean.

Hot water

Given the viscosity and fat content of some of the substances that a motorist encounters, hot water supplied to the washbasin will be a big advantage. For this purpose, if the garage is not attached to the house, you should pay attention to small-volume boilers or flow heaters. True, such systems will work fully and efficiently with ready-made washstands. Homemade devices in this case will be impractical.


There are a number of requirements for the washstand, and there are also some recommendations for its operation and installation. The following points are important:

  • Easy to install using tools at hand.
  • The strength and practicality of the materials used.
  • Sink volume sufficient for hygiene procedures and suitable tap height.
  • Convenient, trouble-free water drain.
  • For self-made devices, it is necessary to provide for a hole for easy and quick water addition.
  • Sophisticated locking system.
  • Good tightness of the device.

IMPORTANT: The structure must be installed away from bare contacts and electrical equipment. Compliance with these two simple safety rules is imperative!

Where to place

For comfortable use of the washbasin and to prevent the negative consequences of its installation, such as leakage, it is recommended to observe the following nuances:

  • It is important to conveniently position the device for unimpeded vehicle passage.
  • For free opening and closing of the gate, the product should not go beyond the wall structure at the entrance to the room.

When installing a handwash, you often have to free up extra space. It is recommended to allocate space in the corner of the garage (most often this is a point near the far wall – especially convenient if the structure is adjacent to a residential area). In general, corner placement has its advantages:

  • You can make a hole with a drain tube to drain the water outside.
  • The device will not create inconvenience to move inside the box.
  • The ventilation located in the lower corner can be combined with a drain.

If all the necessary communications have been carried out to the garage, and if their location is not in the corner part, it is allowed to install plumbing in another place. In this case, it is necessary to ensure unhindered movement inside the building and take care of a comfortable approach to the washbasin.

Drain for water

If you do not plan to use the washstand frequently, then even a simple bucket is suitable for draining water. And if active work is often carried out in the garage, gardening equipment is stored, which is also serviced there, etc., then a thoughtful autonomous drainage system is a necessity. The drainage system in this case will not differ much from the usual sewage system, which is used in houses and dachas. But there are still a few nuances:

  • As a rule, the sewage system in garage cooperatives provides for the installation of a septic tank and piping.
  • The septic tank should be located approximately five meters from the garage.

  • The internal drainage system consists of a conventional piping with hydraulic seals to ensure that there is no bad smell inside the garage.
  • The diameter of the drain pipe should be 80-110 millimeters.
  • Only pipes that are resistant to a variety of chemicals will work.

The drain itself is best installed in a small recess or near the garage door. In the second case, the floor must be made at an angle so that the water can drain itself down. The volume of the drain tank may be different, it all depends on the activity of work in the garage and the frequency of the need to use the washstand. There are small tanks measuring 30 * 30 * 30 centimeters, which are very easy to fix and have an inexpensive cost. And if you need more drainage, then it is worth calculating the approximate volume of water used in a particular garage.

IMPORTANT: Think in advance of the required size of the drain and septic tank, this will save money, since when filling the container, it will have to be pumped out. Calling special pumping out machines is not cheap

How to install correctly

Features of the installation process of the washstand will depend on the selected type of device:

  • The easiest way to install a hand-hung washbasin. It is most often hung with self-tapping screws on the garage door, while water will pour out onto the floor, splashing everything around if you do not use some kind of reservoir.

  • When installing a more complex home-made structure, which includes a sink, you need to fix a container with for liquid on the wall, and make the drain system from plastic pipes. The drain is removed depending on the availability of communications. If they are not there, then the drain is directed into a bucket or vent.
  • If you decide to use an external drain with an outlet through a ventilation hole located near the floor, then it is important to securely fix the pipes. But it is not necessary to completely close the ventilation, as the room must be ventilated.
  • For ease of use, you can hang a lighting fixture next to the washbasin, and nail a shelf for soap utensils and towels.

IMPORTANT: If you do not want everything around to be splashed with water, it is recommended to finish the work area with tiles or other moisture-resistant material. Then the walls can be easily wiped with a rag.

DIY washbasin

In order to build a washstand yourself, you need to understand that it consists of three parts:

  • Water tank. You can use a canister or plastic bottle.

  • Sink. Even a plastic bowl will work. The main thing is that its volume is sufficient.

  • Drain container. The most suitable option is a bucket.

Now let’s look at a few options for homemade washbasins:

From the canister

From materials you will need:

  • Canister.
  • Crane.
  • Plywood and boards.
  • Self-tapping screws.
  • Water collection tank.

First you need to assemble a ramp for the washstand. It should be two-tier. On the first level there will be a canister filled with water, and on the lower level there will be a container for draining. Such a structure can be made from boards and plywood, which are interconnected with self-tapping screws. In the side wall of the plastic canister, you need to cut a hole for a tap with a valve. For good tightness of the product, you need to lubricate the joints with silicone sealant. Next, fill the tank with water and put it on the upper tier of the ramp, and put the container down to drain. Everything, the washbasin is ready to use.

From the bottle

Any plastic bottle and knife will be useful for making such a device. The bottom of the container is cut off with a knife, so that a lid is obtained, which will hold on to a thin strip of plastic. Then the structure is attached to the garage door. Water is poured through the cut top. The neck is screwed on from the bottom with a lid. When you need to wash your hands, the lid is scrolled half a turn to get a thin stream. This must be done carefully, because if you overdo it, the liquid will pour out all at once.

For convenience, a valve can be inserted into the fixture. You need to make a small hole in the lid. Insert a nail into it. Screw a nut with a rubber gasket on top, which, by its weight, when lowered, will block the flow of water.

This option is the simplest, but the service life will be short.

Moidodyr type construction

Such a washbasin is made a little more difficult, but it will be much more convenient to use than previous counterparts.

Useful for manufacturing:

  • Wooden beams.
  • Plywood.
  • Carpentry tools and screws.
  • Sink.
  • Siphon.

So, a frame is constructed from the boards, on which the sink will be installed. It is better to take it the simplest one made of plastic or galvanized steel. We attach the plywood to the frame, a container with water is attached to it. It can be either a bottle product or a canister product. Next, a siphon and a pipe are attached to drain the liquid, which is directed into a drain pit or into a bucket. You need to decorate the finished washbasin at will. You can install the door and cover the drain or paint the wooden frame any color.

Instead of output

It is important to figure out how actively you plan to use the device. It is also necessary to take into account the aggressiveness of the substances that will be in operation – the material of the sink and the quality of the pipes necessary for arranging this structure will depend on this.

We hope that the aspects discussed in the article will help you make the right choice and find something that will simplify your work in the garage.
