Basins

Choosing the right basin is important because it affects both the look and functionality of your space. Whether you're installing a new bathroom sink from scratch or replacing an existing one, these FAQs cover the most common questions we're asked about choosing, sizing and fitting bathroom basins.

 

How do I choose the right basin?

Choosing the right basin really comes down to what works in your space and how you actually use your bathroom. A basin that's too big can make a small room feel cramped, while one that's too small can look a bit lost in a larger space.

It's also worth thinking about the overall look. You can match your basin with the rest of your bathroom suite to keep things consistent, or pick something a bit different if you want it to stand out. If space is tight, a wall hung or cloakroom basin can help keep things open. If you need somewhere to store bits and pieces, a vanity unit is usually the better option.

It's also worth deciding on your tap style before you buy. This affects how many tap holes you'll need, and is something that can't be changed once the basin is made.

 

What size bathroom basin do I need?

In smaller bathrooms or cloakrooms, a compact basin is usually the best option as it won't get in the way. In a larger bathroom, you’ve got more flexibility, so you could go for something bigger or even a double basin if it suits the layout.

It's worth paying attention to both the width and the depth. For example, a basin that sticks out too far can make the room feel tight, especially in narrower spaces. If you're swapping out an old basin, you'll also likely need to work around the existing pipework and layout.

 

What are the different types of basins?

Bathroom basins come in several types, the main ones being:

• Pedestal basins: Classic and versatile, these conceal pipework behind a pedestal and work well in both traditional and modern bathrooms. They're a good choice if you want a straightforward installation without needing a separate unit for storage.
• Wall hung basins: These basins attach directly to the wall with concealed brackets, keeping the floor clear and making the room feel more open. Height can be adjusted to suit, which is useful for accessibility needs.
• Countertop basins: These sit on top of a vanity unit or worktop and work well as a focal point in larger bathrooms. Bear in mind that the tap needs to be fitted to the worktop or wall rather than the basin itself in most cases.
• Inset basins: These basins sit flush within a worktop, giving a more integrated look. They make good use of counter space and are practical in family bathrooms.
• Semi-recessed basins: These partially overhang a unit, which is useful when you want some worktop storage but don't have the depth for a fully inset basin.
• Console basins: Mounted on a decorative stand or legs, these basins suit traditional or period-style bathrooms and often work well as a statement piece.

 

Do I need a basin with one or two tap holes?

This depends on the type of tap you’re planning to use. Basins with a single tap hole are designed for mono basin mixer taps, which combine hot and cold water into one fitting. Basins with two tap holes are suited to separate hot and cold taps. Smaller basins are more commonly fitted with a single tap hole to maximise usable space, while larger basins may offer both options.

If you want to use a wall mounted tap, you may not need any tap holes in the basin at all, as the tap fits directly to the wall above.

 

What height should a bathroom sink be installed at?

The standard height for most bathroom sinks is around 800mm to 850mm from the floor to the rim. This works comfortably for most adults. For wall hung basins the height can be adjusted to suit, which is worth considering if the bathroom will be used by children, older adults or anyone with specific accessibility needs. If in doubt, 800mm to 820mm is a practical starting point for most households

 

Can you install a basin yourself?

Installing a basin is manageable for a confident DIYer, particularly if you're doing a like-for-like replacement where the pipework is already in place. A new installation that involves moving waste pipes or adding new water supply points is more complex and will usually benefit from a plumber's involvement.

The key steps are securing the basin firmly (whether to the wall, pedestal or vanity unit), connecting the waste, fitting the tap before installation where possible as it's much easier to do with the basin off the wall, and checking all connections for leaks before finishing.

The most common mistake is not checking the waste outlet position against the existing pipework before buying, as a mismatch here can mean unexpected extra work on fitting day.
