Most bathroom sinks are durable and last for many years. You may only need to replace them once you decide to renovate the bathroom. But something might happen that obligates you to replace the bathroom sink with a new one. You may be concerned about changing the bathroom vanity while replacing the sink. This process will cost you money. Here is the question, is it possible to replace a sink without replacing the vanity? The answer is Yes, but you need to know how to do that to prevent causing damage to the counter.

Unless the sink was formed as a continuous component of the countertop, it can be removed and replaced easily – whether it’s undermount or drop-in. Though, you will need to make sure that the replacement sink is suited for the same size hole that you already have in the countertop.

How to Remove Sink Without Damaging the Countertop?

First, you should know how different sink mounting types are installed and which type is yours. Generally, undermount sinks are the most difficult to remove since they are installed inside the counter and may be glued to them. Therefore, it is recommended to leave it to a professional to avoid paying extra for a damaged countertop.

Apart from the difficulty you may have in removing an under-mount sink, the process can still be DIY if you care more about each step you take. We explain the steps for removing and installing each type of bathroom sink.

Plumbing

The plumbing process is the easiest part and the same for all types of bathroom sinks:

• Turn off the water supply to ensure you will not get wet during the replacement process.
• Remove the P-trap portion temporarily. It might be a good time to clean it of debris. 
• Since you have to remove the faucets, it is better to unfasten the hot and cold water lines as well. 

Replacing A Vessel Sink

Generally, it is the easiest mounting type because the sink stays on top of the counter. Therefore, you only need to remove it from the counter and place the same type. In these sinks, silicone glue is usually used to affix the sink to the countertop. Now, what should you do to remove a bathroom sink that is glued down? 

You require some tools to soften the adhesive under the sink. Most glues are softened by heat. Therefore;

1. Use a blow dryer to melt the glow. 
2. Use a utility knife to remove the glue underneath the vessel sink. This process may take a few minutes, so it is best to have someone assist you. 
3. Try to move the sink after you heat the glue. The vessel sink is heavy; make sure you can pull it. 
4. Once the sink is removed from the counter, you should clean its place. Use a scraper to scrape the countertop to remove excess glue. 

Since vessel sinks only make a small hole in the countertop for the pipes, you cannot replace them with other types of sinks.

• Glue the new sink to the counter, and make sure that it is placed in the right position so that you do not have a problem attaching the pipes. 
• Do not move the sink until it is firmly attached. 
• Attach the pipes and faucets. Check for any leaks.

Replacing an undermount sink without removing the countertop

Undermount sinks are positioned under the countertop. That is why removing this type of sink is so difficult or somehow impossible. But if you have to replace it with another sink, you should be very careful. Follow these steps:

1. Under-mount sinks are either glued to the countertop with epoxy or attached with mounting hardware holdings such as clips or bolts. 
2. Check the underside of the vanity for any attaching hardware. Loosen them if you find any. 
3. Hold the sink by your hands to prevent it from dropping after removing the clips. You may need help in this step. 
4. Pull out the sink and install the new undermount sink in its place. 
5. Fasten the clips or bolts. Ensure that the sink is stuck to its place and is not loosened.

Removing a glued under-mount sink without replacing the countertop is impossible, especially if it is attached to the countertop with an epoxy resin. If, in any case, you have to remove the sink, we recommend you ask for professional help to prevent breaking the bathroom countertop.

Replacing a drop-in bathroom sink

Undermount sinks are positioned under the countertop. That is why removing this type of sink is so difficult or somehow impossible. But if you have to replace it with another sink, you should be very careful. Follow these steps:

1. If the sink is clipped to the counter, unscrew the clips to loosen the sink.
2. If the sink is glued to the counter, use a blow dryer for a few minutes to loosen the bond.
3. Use a utility knife underneath the sink lip to remove its glue and separate the sink from the countertop.
4. Pull the sink out and scrape the excess glue from the countertop.
5. Put the new sink in its place and screw it to the counter. You may need to use some silicone glue to tighten the sink to its place.

Can we replace a round bathroom sink with square one?

It is generally possible to replace a round bathroom sink with a square one, although it may require some adjustments to the countertop or vanity that the sink sits on.

The first thing to consider is whether the new square sink will fit in the same space as the old round sink. You should measure the dimensions of the round sink and compare them to the dimensions of the square sink to ensure that it will fit in the same countertop opening. If the new sink is larger or smaller than the old one, you may need to make adjustments to the countertop.

Assuming that the new sink will fit in the same space as the old one, you will then need to remove the old sink and install the new one. This process will involve disconnecting the plumbing from the old sink, removing the sink from the countertop, and then installing the new sink. You may need to cut a new hole in the countertop to fit the new sink, or you may need to modify the existing hole to accommodate the square shape of the new sink.
