How Large of a Sink Should You Get For Your New 48 Inch Bathroom Vanity?

Suppose you want to upgrade your bathroom vanity to a really big 48 inch one. Excellent choice!

But what size sink do you need for that new vanity? It’s a big choice that will change the entire look, feel, and function of your bathroom.

So in this article we’re going to share all of the steps on how to decide the sink size for a 48 inch vanity. Let's dive in!

Measure Your Current Area First

Whenever you are shopping for a sink, make sure to have a measurement of the vanity area you’re working with.

Bring a tape measure and go to the toilet. Check the entire width of the vanity countertop from side to side. If you are going for a 48 inch vanity, measure around 48 inches in width.

Be sure nothing is in the way of the sides or back of the vanity area. You don’t want to run out of 48 inches to work with.

Got your measurements? Good. This time, you know just how big a sink you will need. Time to look at options.

Single Sink Or Double Sink?

If you’re a 48 inch vanity you can either go with one huge sink or double sinks, with two smaller sinks. Which is better for you?

Look to yourself for a moment: What do you need?

• Lots of sink use? Many users in the same bathroom? Go 48 inch vanity with double sink.
• Love a big one basin? Freer space for toiletries and sink activities? Lean towards single sink.
• Concerned about cleaning? Doubles require more scrubbing. Singles are less dirty.
• Want a seamless look? Singles bring a sleek, modern style.
• Adding resale value? Most buyers opt for doubles.

Take the plunge on what is most important and use this to decide single vs double sink.

Single Sink Size Options

If you only want one sink, you have a couple of widths to consider:

• 32 Inch Width

It is the most common single sink for 48 inch bathroom vanity.

Pros: Plenty of washing area and space on countertop for toiletries/decor. Creates a clean, simple look.

Cons: Sink is somewhat small for a vanity this wide.

• 37 Inch Width

Doubles the sink footprint and saves on countertop space.

Pros: Very big washing basin. Makes a statement.

Con: Less than an inch of countertop left for tools. Tight squeeze.

• 48 Inch Width

Only one sink, which is the full length of the vanity.

Pros: Completely maximizes sink space. Provides huge single basin.

Cons: No countertop space left. Unclean whole large sink.

The 32 inch size is really ideal as you can see. But select which works for you.

Double Sink Size Combinations

You will be able to select the size of each sink basin. Here are common configurations:

• 16 Inch + 16 Inch

Two equal-sized slimmer sinks.

Pros: Lots of countertop space. Less expensive. Easier install.

Con: Every sink is a bit narrow. Tight squeeze washing hands together.

• 19 Inch + 15 Inch

Combo asymmetrical main sink and second sink.

Pros: Good proportion of sink space & countertop space.

Cons: Uneven sink distribution, visually strange.

• 24 Inch + 18 Inch

An extra spacious main sink basin + average second.

Cons: Gives one big single-function sink. Good washing functionality.

Cons: Reduced countertop space. Higher cost.

24 + 18 works best both in terms of usability and aesthetics.

Specialty Sink Options

On top of regular rectangular sinks, there are also specialty sinks to choose from:

• Oval or Round

Oval or round sink can smooth out your vanity.

Pros: Smooth, flowing lines. Distinctive look.

Cons: Reduced wash space. Higher cost.

• Vessel Sink

Sinks that come on vessel style to the countertop for dramatic appeal.

Pros: Unique modern look. Focal point of bathroom.

Cons: Less functional. Needs very careful sink placement.

• Farmhouse Apron Front

Farmhouse apron paneled sink from the past.

Pros: Timeless vintage charm. Generous washing space.

Cons: Limited countertop space. Higher cost.

The general rule is oval and vessel sinks aren’t for busy baths, but for powder rooms. Yet they can be serious fucking style!

Prioritize Your Must-Haves

The best sink size is to look at your desires:

• Lots of sink space? Go single large or double 24+18.
• Need ample countertop real estate? Lean 32” single or double 16+16.
• Want a showstopping focal point? Consider a statement-making oval, round or vessel sink.
• Prefer traditional look? Stick with standard rectangular shape.

See how your priorities point you towards a great sink size option? Trust your gut.
