How to Choose the Right Bath Size for You

When designing or refurnishing their bathrooms, many homeowners wonder, “What size bath do I need?” Many homeowners make the mistake of ordering a bath without first determining what size bath is ideal for their room. This section will explain how to measure your bathtub before placing an order.

Before purchasing a bathtub, the length, width, and height must all be measured. If you want to replace your current bath, you must first measure it; otherwise, you can measure the area where you want to put your bathtub as your bath dimensions can help determine the right bath size for you.

  1. Length of the Bath

The longest part of the bathtub is the length of the bath; in curved or corned bathtubs, the longest side is the length of the bath. Take this in centimeters or inches with a tape measure.

  1. Width of the Bath

Take the length from the back of the bath to the front with a tape measure to get the width of the bathtub.

  1. Height of the bath

Take a tape measure across the exterior length from the floor to the top border of the bath  to determine the bath’s height. The interior length from the bath’s floor to its top edge is used to determine the bath’s depth.

  1. Type of Bathtub

Bathtubs come in a variety of shapes and sizes; some are better suited to small areas, while others are adequate for larger bathrooms. The sort of bath chosen may be influenced by the user’s bathroom layout, theme, and other features in the bathroom.

The little alcove bathtub, for example, is 54 inches long and 30 inches wide, making it one of the tiniest bathtubs on the market and ideal for people with small bathrooms who don’t want to settle for a shower.

Larger alcove bathtubs are available, as many bathtubs are available in both large and small sizes. Depending on the personal preferences of the user, a freestanding bathtub can be as small as 47 inches long and as large as 72 inches long.

Frequently Asked Questions of Bath Size

What sizes do baths come in the UK?

Due to differences in sizing units, bath sizes in the United Kingdom differ slightly from those in the United States. In the United Kingdom, bathtubs have a standard size of 1700mm (5.5 feet) by 700mm (2.2 feet).

Is a 1600mm bath big enough?

Depending on the type and width of the bathtub, a 1600mm bath might be deemed small or medium. Cornered baths are normally 1600mm to 1800mm long and are considered tiny baths. Double-ended baths, which are considered standard-sized baths, are typically around 1600mm-1900mm (5.3-6.2 feet) in length. Thus, depending on the bath’s style, a 1600mm bath may be sufficient.

Is 1.5 m bath too small?

Yes, a 1.5m (4.9 feet) bath is typically only found in smaller-styled bathrooms such as the free-standing bath or the alcove bathtub. It’s usually warm and inviting, and it gives the room a more traditional look. Other bathtub lengths are typically greater than 1.5m.

What is a standard bath size?

While there is a wide range of sizes in the market, the standard bath size is 60” in length and 30-32” in width. Most bathtub types including alcove baths, cornered baths, and oval baths all have this size, which is considered the average size of bathtubs in the market.

How big is a bath in liters?

A normal bath holds around 302 liters of water, which is roughly 80 gallons of water. On the other hand, a tiny bath may accommodate roughly 150 liters of water, or about 40 gallons of water.

On the other hand, a tiny bath may accommodate roughly 150 liters of water, or about 40 gallons of water.

How big is a 2-person bathtub?

When choosing a two-person bathtub, make sure it is not too large, as this can result in water waste when filling it. At the same time, you want a tub that can easily accommodate two people without being too small. The inside measurement is crucial when purchasing a 2-person bathtub because the outside might be deceiving. Choose an interior that is at least 0.5 meters deep, 1.5 meters long, and 0.8 meters broad. A single-ended bath is more convenient for two people than a double-ended one. Also, bathtubs with taps in the center should also be avoided.

What is the minimum size of a bathtub?

Bathtubs can be as little as 1.2m by 0.8m, and while they are regarded as comfortable and stylish, they are typically used by those who have limited space in their bathrooms and do not want to settle for a shower. The alcove bathtub is the most popular design.

Are all bathtubs 60 inches?

Although most conventional bathtubs are 60 inches long, not all bathtubs are. Bathtubs range in size from 48 to 72 inches in length. This can also happen with bathtubs of the same style that are known to exist in various sizes.

Can I replace a 30-inch tub with 32?

Although replacing a bathtub with one of a different size requires a lot of labor, it is possible to replace a 30-inch tub with a 32″. First, make sure that increasing the size of your bathtub will not crowd your bathroom, and then enlist the help of specialists such as plumbers, since you may need to make some plumbing alterations as a result of the change.
