Single to Double Bathroom Sink Conversion Tips

Converting your bathroom from having a single bathroom sink to a double bathroom sink can seem like a daunting task. There are many benefits, from doubling the existing space to your bathroom looking more sophisticated, however there are a lot of things you will need to make sure of before you begin the project.

Measuring Your Bathroom

The first and most important thing you will need to know before you begin the project, you will need to consider the amount of space you have in your bathroom. Consider things like whether you can fit an extra sink in without extending it, or getting a new vanity, and if you do have to extend it, how that will affect the rest of your bathroom. Tighter bathrooms can be set up like puzzles, with each appliance fit in perfectly, and it may not be possible to extend the counter.

Toilets and bathtubs can be tricky things to relocate, even if you do have enough space. If you decide that you need to rearrange some of your existing appliances, keep in mind that this may require you to have access to the piping behind your walls and be able to make adjustments to existing plumbing. A good method to determine if you have enough space is to map out your bathroom in a blueprint style. It is easier, at times, to get a unbiased view of your overall space when looking at it from the top down. 

Finding a New Sink

You will need to replace the existing sink, hardware and piping when you upgrade to a dual sink configuration. There are many different options to consider when looking for replacements. The simplest solution, is to get an integral basin unit, which is a one-piece counter and sink combination. This will prevent you from having to replace most of the existing hardware, and will make adjustments to your plumbing less demanding. However, if you prefer to install the sink basins individually and replace your existing basin, you will need to get two basins, mounting hardware and the faucet and handle hardware for each basin.

Plan Your Plumbing 

Before you begin installation, keep in mind that the underside of the sinks need to be close enough together in order for the drain plumbing to join together and connect to the drain going through the wall. You can use a tee connector for this, however if the sinks are too far apart, you may need to gain access to behind your wall to join it properly. This turns the project into much more of an ordeal, so it is easiest to avoid it if at all possible and connect the piping on the outside.  

Upgrading your bathroom to have an additional sink can require a lot of planning, work and effort, but it is ultimately worth the time and trouble when you enjoy the benefits with your family.
