Basins are a key component of any bathroom. They’re not just about style; your basin affects how your space functions day to day. With so many shapes, sizes, and installation types available, it’s worth understanding your options before you buy. This guide covers everything you need to know, from the different types of bathroom sinks to sizes, materials, waste types, and how to choose the best option for your home.
What is a basin?
A basin is simply another word for a bathroom sink. It's the unit you use to wash your hands and face, brush your teeth, and carry out your daily routine. Basins come in a wide range of styles, shapes, and types, making them one of the most varied products in any bathroom.
Types of basins
There are more types of bathroom sinks available than most people realise. The style you choose will largely depend on your space, your plumbing setup, and how you want the bathroom to look and function.
· Pedestal basins: A basin supported by a full-length pedestal that runs from the floor to the rim, concealing all pipework neatly beneath.
· Semi-pedestal basins: The basin is wall-fixed with a shorter pedestal that covers only the waste pipe, giving a cleaner, more contemporary look than a full pedestal.
· Semi-recessed basins: The basin sits partially within a vanity unit and partially overhangs it, saving space while still offering useful worktop and storage space beneath.
· Wall-hung basins: Fixed directly to the wall with no pedestal, leaving the floor space beneath completely clear. They’re ideal for smaller bathrooms and easy to keep clean.
· Countertop basins: Designed to sit on top of a surface or vanity unit rather than being set into it, creating a bold, design-led focal point in the bathroom.
· Vanity unit basins: A basin integrated into or paired with a vanity unit, combining the sink with storage below. These are a practical and popular choice for most bathrooms.
· Corner basins: Designed to fit neatly into a corner, making them the most space-efficient option for cloakrooms and compact bathrooms. See our corner vanity units for paired options.
· Inset basins (fully recessed): Set flush into a worktop or vanity unit surface for a sleek, streamlined finish with minimal spillage onto surrounding surfaces.
· Washstands: A freestanding frame or unit that supports the basin, giving an open, furniture-style look.
Bathroom basin sizes
Basin size matters more than people often think. Choose one that's too large, and it can overwhelm the room or make it difficult to move around. Too small, and it becomes impractical for daily use. The width of a basin is the most important measurement to check against your available wall space, but you also need to factor in projection (how far it sticks out from the wall) and depth, particularly if you're planning to fit a vanity unit beneath it.
What is the standard bathroom sink size?
Standard bathroom sink sizes typically range from 450mm to 600mm in width. A 500mm or 600mm basin is the most commonly fitted size in a family bathroom, offering a practical surface area without taking up too much room. If space is tight, sink sizes as narrow as 350mm to 400mm are available and work well in cloakrooms. Explore our small vanity units for compact spaces.
How high should a bathroom sink be?
Bathroom basin height is worth measuring carefully before you buy. The standard bathroom sink height from floor to rim is around 800mm to 850mm, which suits most adults comfortably. As a general rule, the basin should sit at roughly waist height so you're not having to hunch over or stretch up. If children or elderly family members will be using the bathroom regularly, a slightly lower position or an adjustable washstand is worth considering.
Sink depths
Sink dimensions aren't just about width and height. The depth of the bowl (measured from the rim down to the base) affects how much you can fill the basin and how it can be used. Most standard basins have a bowl depth of between 150mm and 200mm. A shallower basin can cause more splashing, while a deeper bowl tends to be more practical, especially if you're filling it to wash your face or rinse items.
Bathroom sink shapes and styles
Basins come in a wide range of shapes, and the one you choose will have a noticeable effect on the overall look and feel of your bathroom.
Round and oval basinshave a softer, more approachable look. They work well in traditional bathrooms and tend to suit classic pedestal or semi-pedestal styles. A round or oval basin works well if you're going for a period or vintage feel.
Square and rectangular basinshave clean, straight lines that suit modern and contemporary bathrooms. They pair particularly well with wall-hung vanity units, countertop styles, and frameless mirrors. If you're after a minimalist or urban look, a square or rectangular basin is likely the better choice.
Corner basinsare their own category in terms of shape but are worth mentioning, as their angular design is purely functional, making the most of a corner space in a cloakroom or compact bathroom.
Bathroom basin materials
The material your basin is made of affects its durability, appearance, and how easy it is to maintain. Here's a breakdown of the most common options.
· Ceramic: The most popular choice by far. It’s durable, easy to clean, resistant to scratches and stains, and available in a wide range of shapes and sizes.
· Porcelain: A denser, higher-fired version of ceramic that produces a glossier finish. It’s slightly harder-wearing, but more expensive than standard ceramic.
· Vitreous china: A ceramic material coated with a glassy enamel during firing. This produces a very smooth, non-porous surface that's highly resistant to staining and easy to wipe down.
· Glass: Toughened glass basins offer a sleek, contemporary look and are particularly effective as countertop bowls. However, they require more regular cleaning to prevent water spots.
· Natural stone: Marble, granite, and travertine basins bring a genuine sense of luxury to a bathroom. They’re heavy and premium in price, but each one is unique. Make sure your surface or vanity unit can support the weight before installing.
· Stainless steel: More common in commercial settings, but used in minimalist bathroom designs. They’re lightweight and long-lasting, though prone to visible water marks and light scratching over time.
Basin waste types
Before you buy a basin, check what type of waste it requires. This is easy to overlook, but fitting the wrong waste type can cause real problems. Basin wastes are not always included with the basin itself, so you’ll likely need to buy the correct one at the same time.
· Slotted basin waste:‘What is a slotted basin waste?’ is one of the most commonly asked questions. A slotted waste has small slots or holes cut into the plug fitting. These slots allow water to drain through the basin's overflow hole, preventing flooding if the tap is left running. A slotted waste must be used with any basin that has an overflow.
· Unslotted waste: Used on basins without an overflow. Because there's no overflow to drain through, the waste has no slots. Fitting a slotted waste on a basin without an overflow, or vice versa, will cause drainage issues.
· Pop-up waste: A lever or push mechanism raises and lowers the plug automatically. Often included with mixer taps, these give a neat, integrated finish with no loose plug to misplace.
· Click-clack (push-button) waste: The plug is pushed down to close and pushed again to open. They’re simple and effective, with no external controls required.
· Plug and chain: The traditional option. A rubber or metal plug on a chain sits over the waste hole. They’re straightforward and easy to replace when needed.
How to choose a basin
With so many options available, it helps to work through a few key considerations before you make a decision.
1. Consider your space:Measure the wall space available, the projection into the room, and the floor space below. If space is limited, a wall-hung basin or a corner basin will give you more room to move. For more inspiration, read our blog on small bathroom ideas.
2. Think about your plumbing:The mounting type you choose will determine how your pipework needs to be configured. Wall-hung and pedestal basins expose pipework differently. Some options, such as countertop basins on a vanity unit, are easier to install in certain layouts than others.
3. Choose your mounting type:Wall-hung basins require fixings into the wall and must be anchored securely, as they carry weight without a floor-mounted support. Pedestal and vanity-mounted basins are generally more straightforward to install.
4. Decide how many tap holes you need:Most modern basins come with a single tap hole, designed for a mono mixer tap. If you prefer separate hot and cold taps, you'll need a basin with two tap holes. Three tap holes are used for a three-piece tap set. Check this before purchasing your taps.
5. Think about who will be using it:Standard bathroom basin height suits most adults, but if the basin is for a child's bathroom or for someone who struggles with standard heights, it's worth considering an adjustable washstand or planning a lower installation position.
6. Don't forget the accessories:You'll need to purchase a basin waste separately in most cases, and you may also need a bottle trap or pipe cover to keep the plumbing tidy beneath a wall-hung basin. You may also want to consider the material and colour of your taps.
