Bath Sizes Explained

When it comes to remodelling, size matters, with a bathroom, makeover baths are generally the focal feature of the room, so it’s important to make a perfect choice. However, finding the ideal model to feature in your home isn’t all about aesthetics. It is vital to consider size and proportionality.

Every space presents its own unique challenges when it comes to layout. If you’re new to remodelling, you might wonder: well, what’s the UK standard? Surely, the average bath size will work for me.

Is there a standard size?

Previously in the UK, when the imperial measuring system was the standard, the typical bath size was 5’6” in length, in metric, this is a 1675mm bath. Now, the metric system is used to measure UK bath size, and the current standard bath size in the UK is 1700mm in length and 700mm in width.

So, if this is the standard size, surely that’s what everyone should be going for? Not quite! Many great bath options are smaller or larger than the standard. Every customer should consider the distinctive criteria of their home to see if the standard UK bath size will actually work.

Some customers might be working within a limited space or an unconventional layout that requires an unconventional bath (for example, rooms with nooks or slanted walls). These customers might consider a small bath or a corner bath, which falls below the UK standard size.

On the other hand, some customers might be looking for a large bath to look proportional within a larger space. Others might seek a double-ended bath to accommodate bathing with a partner.

Others might be drawn to the grandeur of an especially deep, luxurious free-standing bath, which is generally a larger and deeper bath size than the UK standard.

Others might want a tub that aligns perfectly with their tiled wall. Plus, other modern and quirky designs, such as the L-shaped, P-shaped, and B-shaped baths, might catch customers looking for something different.

Read on to learn our tips, tricks, and hacks for measuring your current bath and choosing your new tub. Plus, screenshot our detailed information on bath size dimensions to keep handy on your remodelling journey.

Measuring A Bath

So, if you’re spoiled for choices with various shapes and bath sizes, how do you make the correct decision for your new bathroom?  The first thing to do is measure your bathroom wall and floor space dimensions, then measure the length, width, height, and depth of your current bath.

This will let you know the dimensions you’re working within and how flexible you can be with size when selecting a new model.

How to measure the length of a bath

First, record the length. Place a tape measure at the head of the bath, and stretch it across the top of the bath lengthways in a straight, non-diagonal line. Make sure you begin at the widest part of the rim on a curved or corner bath. Record the measurement.

How to measure the width of a bath

Find the widest point in the bath, and stretch the tape measure across the width of the bath in a straight line. Record the measurement.

If you have an unconventional shape, such as an L-shaped, P-shaped, or B-shaped bath, record the widest and slimmest part of the bath so you have all the dimensions you could need when planning your layout.

If you are considering implementing a tiled wall, you might need to consider the space the tiles will take up when installing your bath.

How to measure the height of a bath

Place the tape measure on the floor next to the bath. Stretch the tape measure upwards until you reach the edge of the bath. Record the measurement.

How to measure the depth of a bath

To work out the maximin depth of water, your bath will hold place the tape measure at the bottom of the inside of the bath to begin recording the interior depth. Measure from the deepest part of the bath to the overflow.


How to measure the depth of a bath

To work out the full depth of your bath, use something straight like a wooden ruler or a piece of wood, and lay it across the width of the bath (being careful not to scratch the bath)

Then measure from the bottom of the bath to the underside of the wood you have placed across.

Which bath size is right for me?

As discussed, the perfect tub isn’t a one-size-fits-all solution. There’s space, practicality, design, and personal preference to consider.

Not everyone has the same taste, but everyone wants their bath to look good, feel comfortable, and fit properly. Here are some tips for matching your style to your space if you don’t know where to start!

Stick with the classic

If you want a simple, classic, no-frills tub that gets the job done, we’d recommend a single-ended bath around the standard in UK bath sizes (1700mm in length and 700mm in width). You can’t go wrong with this option.


Why not consider a double-ended bath for larger bathrooms you’re unsure how to fill? These models are larger and offer a greater presence in the room and a greater sense of luxury whilst bathing. Double-ended tubs usually accommodate two people, which is a great option for couples and families.

Space-saving corner baths

Conversely, if you are concerned about the size limits of your bathroom, corner baths can be a great way to save space. These baths are ideal for rooms that don’t offer extended, straight walls for an elongated standard bath.

These space-saving models can transform the most difficult spaces by utilizing corners while looking cool, contemporary, and resourceful.

Letter shaped bath

Why not consider an L-shaped, P-shaped, or B-shaped bath for other contemporary, modish styles? These baths add a fashionable flair to the room and can perfectly complement a statement-tiled wall.

A touch of vintage

If you’re won over by the classical vintage theme but are worried about the size of a free-standing model when you’re short on space, all is not lost! A standard single-ended straight bath can achieve an elegant, vintage look with a timeless panel. Check out our traditional straight bath panels.

However, if you dream of vintage bathrooms with Parisian flair and have the space, you should consider a classic-look freestanding bath. Who can resist a quintessential bubble bath in an ultra-luxurious cast-iron tub?

Whether you want a streamlined modern tub or an old-fashioned fantasy, the perfect size, shape, and style are for you. Measure up your bath and browse our site to determine the ideal option for your remodel.


What are standard bath sizes?

The standard bath size in the UK is 1700mm in length and 700mm in width. It is estimated that across the UK’s bathrooms, the standard bath size is approximately 2.3m x 2.7m.

What is a good size for a soaking tub?

A deep soaking bath is fantastic for those who love relaxing, unwinding and relieving stress in a tub that offers a fully immersive soaking experience.

Taking the plunge with a soaking tub generally means accommodating a significantly larger bath, so you may need more space in your bathroom to fit this size tub.

The size of soaking tubs depends on the luxury the customer seeks, but they are generally significantly above the average height and length.

They range from around 60” in length to a tremendous 90” (2286mm!) or more. We’d recommend ensuring that your soaking tub has a depth of 14” to 15” at minimum.

Some Japanese soaking tubs are over 20” deep to allow users to submerge when they soak fully.

Are small baths any good?

Small baths aren’t right for everyone, but a slightly smaller model is ideal for many customers. Large baths don’t work in all homes. Some people work in a tricky layout or need to accommodate a separate bath and shower.

In these cases, smaller baths aren’t just good; they’re an excellent option for maximizing space and costs.
