To begin with, installing an undermount bathroom sink is easier than you think. There are two main methods that you can follow to install your undermount bathroom sink. Let’s get to know the first method that you can follow.
Apart from the bathroom sink, you will need the following tools
- Measurement Tape
- Adhesive cleaner
First of all, use the measurement tape to measure the depth of your cabinet and the depth of your sink. Try to be closely precise because you need to cut the wood based on the measurement. In this installation method, we will use the aid of shims to complete our installation.
Secondly, now that you have the measurement perfectly cut the wood. This wood will act as the brace and help support the sink until the adhesive has perfectly got its grip.
Thirdly, get your undermount bathroom sink and get it in position. Make sure the position is right. You do not want to mix up the front side with the back. Usually, place the deep side at the far end because it will allow the best hand-washing experience.
Fourthly, get your silicon-based adhesive and perfectly put it all around the sink. Take the sink upholding from under it to ensure that adhesive does not get in contact with your clothes or hand. You can also use the drain hole of the sink to move it around. Once you put the sink in position put the wood under it. Use the shims to make it more firm.
Finally, you need to clean the adhesive from all the corners of the sink. You can use a paper towel to clean it up. Some adhesives may require additional chemicals to properly clean them out. Now, you need to leave this for a day or two so the adhesive can harden and get a firm grip.
Great, you have just learned how to install an undermount bathroom sink. We have mentioned a second method earlier. The second method also follows the same principle but using different tools.
This method installs the sink from the top and you will need the following tools for the installation
- 2×4 Dimensional lumber
- Half inch threaded rod
- Galvanized bolts for the rod
This method is also very simple. First of all, you need to create a hole in your 2×4 lumbers. Secondly, put the threaded rod in the drain hole of the sink and the two 2×4. Thirdly, use the bolts to fix the woods above and below the sink. Now you should have one wood holding the sink from above your countertop with the help of the other wood under the sink with the support of galvanized bolts. Everything should be in position at this moment. Put the adhesive carefully all-around your sink. Use a wrench to tighten the sink with the countertop. Finally, clean the extra adhesive from the sink. Congratulations, you have learned the second method too.
