A bath plays an essential role in any home, from busy midweek bath times with the kids to a relaxing soak at the end of a long week, so choosing the right one can make all the difference. As the centrepiece of your bathroom, it also needs to look the part while standing up to everyday use. Get it right, and your bath will serve your household for years to come. This bath buying guide covers everything you need to know about buying a bath, from size and shape to material and price.
1. Bath type
There are more types of baths available than most people realise. Understanding the bathtub types before you shop will save you a lot of back-and-forth. Here are the main ones on offer:
· Freestanding baths: A statement piece that sits away from the wall, available in classic roll top, slipper, and contemporary sculptural styles.
· Corner baths: Designed to fit neatly into a corner, making good use of space in larger bathrooms while offering a generous soak.
· P-shaped and L-shaped baths: Wider at one end to create a shower area, ideal if you want a bath and a shower in one footprint.
· Double-ended baths: Taps in the middle and sloped ends at both sides, so two people can recline comfortably. Great for larger bathrooms.
· Single-ended baths: The most common layout, with taps at one end and a sloped back at the other. Practical, space-efficient, and widely available.
· Slipper baths: Raised at one or both ends for a more upright, luxurious recline. Often freestanding and a real focal point in a room.
· Shower baths: A practical choice if you want both a bath and a shower without sacrificing floor space.
· Whirlpool and Jacuzzi baths: Fitted with jets for hydrotherapy. A genuine upgrade if you enjoy a therapeutic soak. Read our ultimate guide to whirlpool baths for more information.
2. Bath shape
The shape of your bath affects both how it looks and how comfortable it is to use. Rectangular baths are the most common and work well in most bathroom layouts, fitting neatly into alcoves or against a wall. Oval and circular baths tend to suit more contemporary or freestanding designs, and feel more indulgent. If your bathroom is compact, a straight rectangular bath will always make the best use of available floor space.
3. Bath size
Getting the size right is one of the most important decisions when buying a bath. When considering your bath dimensions, think about your bathroom size and available space, as well as your height, to ensure comfortable bathing. The average bath size in the UK is 1700mm long x 700mm wide x 520mm high. That said, baths are available across a wide range of sizes to suit different bathrooms and bathers.
Bath lengths range from 1200mm to 1900mm. As a rough guide:
· 1200mm and 1300mm: Small baths, good for en-suites or compact bathrooms
· 1400mm and 1500mm: Mid-range sizes that work in most family bathrooms
· 1600mm and 1700mm: The most popular lengths; the 1700mm is widely considered the standard
· 1800mm and 1900mm: Large baths suited to bigger bathrooms or taller bathers
How wide is a bath?
Most baths sit between 700mm and 800mm wide, though freestanding and double-ended models can be wider. Narrower options (around 650–680mm) are available for very tight spaces. Before ordering, measure the bath area carefully and check the route from your front door to your bathroom. Doorways, hallways, and staircases can all cause problems on delivery day.

4. Bath height
The height of bath you choose affects both the look of the room and how comfortable the bath is to get in and out of. Most standard baths sit between 500mm and 600mm high. A lower bath can look sleek and contemporary, but may be harder to get into for older bathers or those with mobility concerns. A taller bath gives you more depth and a better back rest, which some people find more comfortable for a long soak. Freestanding baths often sit higher due to their feet or plinth.
5. Bath depth
Depth is closely linked to the bathing experience. The standard bath depth is typically around 400–450mm of water capacity when filled to a comfortable level, though the internal depth of the bath itself can vary from around 350mm to 500mm or more. A deeper bath holds more water and allows you to submerge more of your body. That sounds appealing, but it’s worth considering your boiler and hot water capacity before choosing a very deep model. A larger volume means more water to heat, and if your system can’t keep up, you’ll be topping up with cold water. Check your water pressure, too. A slow-filling bath with a high-depth tub quickly becomes frustrating.
6. Bath material
What are baths made of? There’s no single answer, as different materials offer different benefits. The material you choose directly affects the bath’s weight, warmth, durability, price, and overall feel. Understanding the different options will help you pick the best bathtub material for your home. Here’s how to choose the best material for your bath:
· Acrylic: Lightweight, affordable, and available in the widest range of shapes and colours. Easy to repair if scratched. The most popular choice for everyday bathrooms.
· Fibreglass (GRP): Similar to acrylic in weight and price. Less durable over time but a cost-effective starting point.
· Steel (enamelled): Heavier than acrylic with a hard, glassy surface. Retains heat well and feels premium underfoot. Chip-resistant when treated with enamel.
· Cast iron: Extremely durable and excellent at retaining heat, keeping your bath water warm for longer. Heavy (often 100kg+), so floor reinforcement is usually required.
· Stone resin: Dense, smooth, and luxurious. Excellent heat retention and a high-end look. Heavier than acrylic; floor checks are advisable.
· Carronite: A reinforced acrylic composite that combines the lightness of acrylic with improved rigidity and a solid feel underfoot.
· Copper: A real statement piece. Naturally antimicrobial and virtually maintenance-free, but often more expensive. Floor reinforcement is required.
· Natural stone: Exceptionally durable and unique. Each bath is slightly different. Very heavy and expensive; not suitable for all floor types without structural work.
Note:Baths made from heavy materials such as cast iron, copper, and natural stone will require bathroom floor reinforcement before installation.
7. Bath thickness
The thickness of the bath’s shell affects how rigid and solid it feels underfoot. For acrylic baths, standard thickness is typically around 5mm, though reinforced and premium models can be 8mm or more. A thicker bath flexes less when you move around in it, feels more substantial, and generally lasts longer. When comparing acrylic models in particular, it’s worth checking the bath thickness specification. A 5mm bath is perfectly serviceable, but anything below that may feel less sturdy over time.
8. Bath colour
Baths come in a range of colours and shades to suit every bathroom style. Most baths at Bathroom City are available in classic white, which suits most bathroom decor and never dates. If you want something more distinctive, other options include matt black, grey, stone effect, and wood-look finishes, as well as warm metallic tones such as brushed gold. Before choosing a colour, consider the rest of your bathroom scheme. A bold-coloured bath works best when it’s the focal point of the room rather than competing with other statement features. White remains the most practical choice for resale value, but the right coloured bath in the right setting can look genuinely striking.
9. Bathroom layout and plumbing compatibility
Before committing to a bath, think about where the taps and waste will sit and whether your existing plumbing can accommodate them. A single-ended bath positions the taps at one end, which suits most standard layouts. Double-ended baths require a central tap position, which may mean moving pipework. Also consider the waste position. Left-hand or right-hand waste outlets need to align with your existing drainage. If you are changing the type of bath significantly, it is worth speaking to a plumber before you order to confirm compatibility and avoid unexpected costs.
10. Ease of installation
Some baths, particularly freestanding or oversized models, can be difficult to manoeuvre into place. Tight hallways, stairs, or narrow doorways can complicate both delivery and installation. It is worth measuring the access route carefully before you commit to a bath that physically won’t fit into your home. Check doorway widths, stair turns, and the final position in the room. If in doubt, our customer care team can advise.
11. Bath price
Bath prices vary considerably depending on the type, size, and material. Acrylic baths start from around £150 and represent excellent value for everyday use. Solid-surface and stone-resin baths sit at the higher end, along with freestanding roll-top baths, which are among the most expensive options. Don’t forget to factor in installation costs, which will vary depending on whether you’re replacing a like-for-like bath or moving plumbing.
12. Your household
Before choosing a style or size, think about how the bath will be used day to day. If your routine leans more towards quick showers with the occasional soak, a shower bath is a practical way to combine both without taking up extra space. Taller users will benefit from a longer bath, typically 1800mm or 1900mm, for added comfort, while families with young children may prefer a wider design with a manageable depth for safe and easy bathing.
For older or less mobile users, features such as grab rail compatibility and a non-slip base can make all the difference. And if you enjoy a long soak, it’s worth choosing a bath that properly supports your body, with enough length to stretch out and a shape that follows the natural curve of your back.

13. Bath fixtures and accessories
A bath rarely works in isolation. Here is what to consider when it comes to the finishing details:
· Bath taps: Available in a wide range of styles and finishes, from chrome and brushed nickel to matt black and brushed gold. Taps do a lot of visual work, so choose a finish that ties in with the rest of your bathroom. See our bath taps buying guide for help choosing.
· Bath wastes and traps: The three key components are the plug, overflow, and trap. A quality waste drains efficiently and should match your tap finish for a cohesive look.
· Bath panels: Create a clean, finished look by concealing the underside of the bath and the pipework behind it. Available in various finishes to complement your bathroom decor. Read more in our bath panel ideas guide.
· Bath screens: Glass panels that keep water contained when showering over the bath. Available in hinged, fixed, and square styles.
14. Bath warranty
Warranties vary across the range, from one year on entry-level models up to lifetime guarantees on certain premium baths. As a bath is a long-term fixture, it is worth checking the warranty length before you buy. A longer warranty gives you confidence in the product’s build quality and protects you against manufacturing defects for years to come. Check the individual product listing for warranty details or ask our team for guidance.
There is no single right answer to choosing a bath. The best option depends on your bathroom size, how your household uses the bath, your budget, and the style you are going for. Get the practical decisions right first (size, material, plumbing compatibility), and the aesthetic choices become much easier.
