To improve the appearance of your bathroom and make it look sleeker and more elegant, no other addition except that of the sink can have a better effect.
The sink is the most crucial fixture in a bathroom. An under-mount sink will give you a cleaner look and would also go with the rest of your bathroom décor.
An under-mount sink can be easily installed to granite and is not a tough job. For the plumber, its installation would be a similar hassle as that of a top mount sink.
To get further details about this, reading through the article will tell you how to install undermount bathroom sink to granite.
What Do You Need?
Before starting, gather all the items required to do the task. The following list has all the things needed before getting down to the real job.
Sink: When selecting from the innumerable options you see in the store, remember the kind of granite counter you have.
Do not choose something which looks good by itself only. So, the design and texture of the under-mount bathroom sink must match with your counter.
You must be careful if you choose a composite sink as it may stand in plain contrast with your counter and make the entire setup look gritty. You can go online or look up online for sinks.
The tools required to install undermount bathroom sink are:
- Screwdriver
- Power drill
- Drill bit
- Silicone Sealant
- Wingnuts
- Clamps
- 2×4 lumber
- Pencil
If your sink does not have mounting hardware, it should be bought separately.
How to install undermount bathroom sink?
The installation process will take a lot of time, so it must be started on a free day, so you have plenty of time to do everything carefully and precisely.
Step 1
The graphite should be drilled with some holes; this can either be done on your own using a power drill machine. A drilling attachment tool with the perfect size for screws to fit in will be needed.
Else, there will be no use of it. If you haven’t done this before, it is suggested to get this part done by someone who already has.
Getting professional assistance will help you work efficiently with the power drill when you have never done it yourself.
Step 2
Please measure the length of the hole in your counter now and cut it 2×4. This should be precisely 1 foot longer than the gap present in the counter.
Align the 2×4 according to the width and put it over the hole, such that 4-6 inches of 2×4 rest on the graphite counter top’s each side.
Ensure its stability on the hole, as this 2×4 will be used as the contact points to measure the sink’s placement as it is pulled with a clamp.
Step 3
For this step, all measurements must be taken very precisely. It is merely about scaling and ensuring the layout is correct for the clamps.
Start by using the 2×4 and drain holes of the sink as your reference points.
Pull the sink to the counter’s underside with your bar clamp, and clamp it with care. Make sure the clamps are not tightened too much, or the granite surface will be damaged.
There should be a snug fit in the hole. To ensure that the job is done correctly, try to move the 2×4 lumber. It should shift just to the most minute angle along the counter.
Step 4
Once the layout of measurements ready, fasten the wingnuts in the screws, which will hold the sink. Check the alignment of nuts with the design, if everything is as per plan, proceed to the next step.
Make sure it is done accurately. Otherwise, the nuts will have to be opened again. Once the alignment is in place, mark the spots of wing nuts. Unclamp the sink and put it aside for the time being.
Step 5
Look at these pencil marks and using a 1/4th drill bit, drill holes with pencil marks. The graphite may get scratched off, so you must be very cautious during this step.
Clean the area once the holes have been drilled properly. Clean the ridge completely using rubbing alcohol.
Step 6
Put a slight beam of the silicone sealant at the ridges and ensure that the lines are straight and clear. Bring the bathroom sink up quickly now and put it on the beam.
Using the bar clamp, clamp it at the correct spot now to hold it securely.
Thread wing nuts in the drilled holes and tighten all the screws once you are finally done. Rub all the residual sealant from the ridge edges before it dries.
And there it is – your perfectly secured set up in the bathroom.
You have to wait for the sealant to dry out now, which may take a whole night as well. Check for any leaks the next morning, which may be looked over.
If everything has hit the right spot, you can quickly go ahead to fasten all the plumbing fixtures.
Installing an under mount bathroom sink is not a tough task, but it requires absolute precision, so you need to be very focused and careful.
Any step if goes even slightly wrong by angle or accuracy, you may find yourself doing the entire thing again.
