Underframe for kitchen sink: DIY video instructions for installation, price, photo

In modern interiors, it is rare to see kitchen sets from separate cabinets that are not connected by a common tabletop. And an overhead sink with a base for the kitchen is perceived as a relic of the past, an outdated and not very convenient option, acceptable only in the country or as a temporary solution.

Indeed, the flush sink looks neater, does not violate the integrity of the desktop, and it is more convenient to use it, since you can not be afraid that moisture will penetrate into the gap between it and the end countertops. But the countertop washbasin with a base has its own advantages.

What is underframe

Underframe is a floor stand without a back wall and kitchen countertops for installing an overhead sink on it. The dimensions of the cabinet in a horizontal projection must correspond to the size of the sink so that it fits snugly into place.

Dimensions and execution

The dimensions of the cabinet are selected depending on the size of the kitchen, your needs or based on the parameters of an existing sink. The latter can serve not only as a bowl for washing dishes, but also as a countertop, and should be on the same level with the working tables of the modules standing next to it.

The underframe for the kitchen sink is available in standard sizes.

Its width can be 500, 600, 800 and even 1200 mm.

• Sinks for small pedestals have one bowl and a narrow side around the perimeter, and the underframe itself is equipped with hinged kitchen facades.

• Sinks for larger double-leaf cabinets can have two bowls or a drainer for drying dishes, as in the first photo.

For reference. Since there is a drain, hot and cold water connections, and sometimes filters for cleaning it under the sink, the base for it most often goes without internal filling.

The material for the body of the underframe is usually chipboard, and the facades can be made of any other materials used for the kitchen.

Benefits of an underframe with an overhead sink

Do not think that overhead sinks are used only in budget economy class kitchens. Today, there is a clear tendency to decorate interiors in a classic, country or retro style, and in them this element looks much more harmonious than a sink cut into a common countertop.

Original DIY underframe

Therefore, we can confidently argue with those who consider such a decision to be “the last century”.

Note. Today, overhead sinks for the kitchen are produced not only from stainless alloys and enamelled steel, but also from such modern materials as ceramics and artificial stone.
And to install them, you need floor-standing cabinets that are appropriate in style and quality.

In addition to creating a certain design, underframes also have such advantages as:

• Possibility of self-assembly kitchen sink. If it is selected correctly, it will be easy to install it even for a person who first took up such a business.
• If necessary, the sink can be temporarily removed in order to carry out plumbing repairs.
• Low price is the main advantage if you need to equip a kitchen in the country, in a rented apartment or in another similar situation.
• Reducing the cost of kitchens with stone countertops. The cost of a solid stone countertop with a recessed sink is very high.
  Whereas the installation of an underframe with an overhead sink will reduce the price by an order of magnitude and will not spoil the design.

Assembly and installation of the underframe with sink

As mentioned above, assembling a cabinet and installing a sink on it is a simple matter. On this page you will find a video on how to do it yourself.

As a rule, cabinet furniture is delivered to customers disassembled, complete with all necessary fixing and front fittings and assembly instructions, so you can easily assemble the underframe. Some questions can only be caused by the installation and connection of the sink.

Council. Do not screw the facade to the cabinet until you have finished installing the sink and connecting it to communications.

Assembled underframe

Further instructions will help you get the job done.

1. If the set with the underframe did not come with special mounts for the sink, purchase them yourself. They are L-shaped plates with an oblique slot on the vertical plane.
   You will need 4 of these mounts.

Sink fasteners

1. Attach the fasteners to the end of the side wall so that the plane with the slot is on its inner side, and circle the slot with a pencil.

We mark the attachment points

1. Remove the fasteners, screw the self-tapping screw just above the lower marking point and reinstall the mounting plate, already on the self-tapping screw.
2. Prepare the sink for installation: fit a siphon and a mixer into it.
3. Apply silicone sealant to the ends of the underframe to protect the chipboard sections from moisture and swelling.
4. Carefully, without touching the sealant, insert the sink into the hole in the cabinet.
5. Move the fasteners on the self-tapping screws so that the sink is firmly pressed against the ends of the underframe.

Tightening the fasteners

Installation completed. It remains only to connect the mixer connections to the water pipes, and the siphon to the sewer pipe, to hang the facade.

Note. If, when tightening the fasteners, excess sealant has leaked out on the cabinet walls, they must be immediately removed with a rag.

Conclusion

The information presented in this article may be useful to owners of modular kitchen sets from separate cabinets. Even if this is not the most modern and fashionable option, it is still actively used by thousands of people.
