Greetings and welcome to "All about Concrete," your one-stop shop for all things concrete-related. We’ll walk you through the process of making a DIY concrete sink in this guide, which is ideal for giving your house a distinctive touch. Although creating a concrete sink can seem difficult, it can be a rewarding project that blends modern design and functionality with the correct planning and guidance.
Concrete sinks are becoming more and more popular because of their adaptability and longevity. Without the need for specialized skills, this step-by-step plan will assist you in creating a custom outdoor sink or remodeling a kitchen or bathroom to look professional.
Prior to beginning the project, make sure you have all the required supplies and equipment. Concrete mix designed especially for countertops or sinks, reinforcement fibers or mesh for strength, a sink mold (which can be made yourself or bought), form oil or release agent to help with demolding, and simple tools like a drill, mixing paddle, and trowel are required.
The secret to a successful concrete sink is preparation. First, arrange your workspace so that it has a strong work surface and is well-ventilated. To make the removal of the cured concrete easier, make sure your mold is clean and covered with the release agent. To prevent any mishaps during the pouring and curing stages, take your time measuring and verifying your dimensions.
Let’s begin combining the concrete now. The proportions for mixing should be according to the manufacturer’s instructions, as they may change based on the kind of concrete mix you’re using. To achieve a smooth, pourable consistency, thoroughly blend the concrete using a drill equipped with a mixing paddle attachment. In order to achieve a uniform finish and avoid air pockets that could weaken the sink, this step is essential.
Pour the concrete into the prepared mold carefully after it has been mixed. Utilize a trowel to smooth the surface and work methodically to guarantee even distribution. To get a smoother finish and free trapped air bubbles, you might need to gently vibrate the mold, depending on the design. As directed by the manufacturer, let the concrete cure, covering it with plastic sheeting to keep moisture in and encourage the development of strength.
Gently remove the mold to reveal your newly formed concrete sink after the curing period. When doing this, exercise caution so as not to harm the surface or its edges. Let the sink cure completely before doing any sealing or sanding. Any unevenness or sharp edges can be smoothed out with sanding, and to extend the life of the surface and prevent stains, use a food-safe concrete sealer.
Once you’ve finished these steps, you can install your DIY concrete sink and take pleasure in having a handmade addition to your house. Whether you choose a sleek modern design or a rustic farmhouse style, personalizing your concrete sink lets you show off your artistic vision while enjoying a long-lasting and attractive fixture.

Features of the material
A concrete sink must be produced through a number of steps and with the right selection of raw materials. Sand, cement, and special additives are used to cast a concrete sink in a formwork. If desired, decorative elements like quartz, marble, or granite chips can be added.
The quality of the product will directly depend on the correct preparation of the solution for pouring it. In addition, it is important to find or create a suitable form (formwork) that will help create a product of the desired configuration, with drains and overflows for water. After pouring, the sink is removed from the formwork after 7 days, when the gained strength is already sufficient.
The concrete is polished and ground to enhance its moisture resistance and aesthetic qualities after it has reached its maximum strength. Every bend, every corner, and every hole are processed to the highest standard. Applying varnish to the sink is the last step in the process, providing water and dirt resistance.
- Do not use hard sponges and abrasive cleaning agents with aggressive components – all this damages the protective layer on the product.
- Use citric and acetic acids very carefully.
- It is advisable to clean concrete sinks regularly with soft cleaning agents and tools.
- It is advisable not to place hot objects on the sink or cut food.
- It is necessary to avoid dropping heavy and sharp objects on the edges of the sink, especially on its corners.
- The protective coating on concrete gradually wears out, so it must be periodically updated and defects must be restored in a timely manner.
Over an extended length of time, a concrete sink may develop microscopic cracks on the surface. These cracks are not a flaw and have no effect on the sink’s durability or functionality. Erroneous component selection in the concrete solution or a breach of the technology used to create the product can result in large cracks.
It is best to mix an M300 sand concrete solution and stay away from significant filler fractions in order to achieve a refined and smooth concrete surface. A specific volume of plasticizer is added to the mixture to help make the sink surface smoother.
Different dyes and pigments are added to the still liquid solution to give the concrete a desired color. After grinding is complete, painting the sink is acceptable. The pigment shade will appear brighter and more saturated when white Portland cement is used.
- A beautiful and high-quality sink will be obtained from a mixture that uses M400/M500 cement.
- As a filler, it is best to take fine-grained, cleaned and dried sand with a size of 1.2-2 millimeters.
- It is advisable to select the proportion of components 1:3 (1 part cement and 3 parts sand), subject to the water-cement ratio of no more than 0.5.
- The plasticizer is added to the solution in the volume specified by the manufacturer in the instructions.
- The finished mixture should have a consistency similar to wet sand after rain, but plastic.
It will be challenging to produce a high-quality product without a vibrating table or plasticizer, but you can attempt to evenly knock on the formwork once the mixture is poured until the cement milk emerges on the surface.
Formwork material
The best materials for the formwork are fiberboard bars or the necessary size sheets of moisture-resistant plywood, plastic sheets, and boards. The sink bowl’s smooth, precisely matched shape is the most crucial aspect to consider. For more complicated configurations, galvanized steel sheets can be used.
Use reinforcement in the form of steel rods with a cross section of 10–15 millimeters to give the structure stability, strength, and dependability when fastened to the wall. When installing reinforcement beneath a sink bowl, it is recommended to use a step of 10–20 centimeters; if a tabletop is also being created, a step of 20–40 centimeters is best.
Because a reinforced concrete sink is heavy, it needs to be secured with particularly sturdy supporting structures. In order to achieve this, reinforcement is put through penetration into the wall, with the necessary length of rods pre-provided.
The formwork is robust and monolithic, with particular attention to the joints. Using metallized tape, corners, and sealants is advised. Dowels and screws are used to secure the formwork components. It’s crucial to prevent any cracks, irregularities, or weak spots because cement can spill and is quite heavy.
The structure dries under a polyethylene film after pouring. During the concrete strength gain process, it is advisable to set up temporary supports that can bear the weight of the structure. Bricks are most frequently utilized for this purpose.
External finishing and tools
There are several ways to finish the outside of the sink. The easiest is using a special machine to grind and polish, then varnishing. Another option is to finish the countertop with tiles, which leaves the sink in its original configuration. Moreover, decorative filler mixed with concrete mortar is used; various patterns and elements can be arranged on the outer layer as the pouring process proceeds.
- Electric jigsaw or other tools for processing the material from which the formwork will be made.
- Perforator and concrete drills for drilling holes for reinforcement.
- Screwdriver or screwdriver, metal scissors and hammer.
- Welding machine for securely fixing the reinforcement.
- Container for mixing concrete, mixer for uniform mixing of components.
- Measuring tools – tape measure, ruler, plumb line, building level, pencil.
- Spatulas of different sizes for applying the solution.
