The height is around the same as other tubs at 14inches to 20 inches, the length can range from 45 inches to 72 inches, and the width varies from 30 inches to 32 inches, but as mentioned earlier, you will need a foot of extra space around the tub so ensure to include that in your measurements.

Walk-In Bathtubs

If you are experiencing health issues or just find it difficult to get in and out of your bathtub, then a walk-in bathtub may be the answer. A door on the side of the bathtub allows easy access while grips and handrails provide extra support eliminating any accidents.

These bathtubs can come with a seat for extra comfort and are generally wider and taller than the other bathtubs. The widest of all bathtubs at 50 inches to 60 inches and 36 inches to 42 inches in height make them easy to soak while sitting and a length of 30 inches.

How to Measure a Bathtub

It is not enough to know what size tub you want but how much space you have. If you have an existing tub, then measuring around it will give you a good idea of the available space. Remember always measure twice and make sure to double-check your measurements. There are a couple of factors that will need attention before you make the final decision.

1. Plumbing Location

If this is a new bathroom and you need to measure for a new bathtub, then locating the plumbing will essentially determine where the bathtub will sit in the bathroom and, ultimately, how big the bathtub can be.

2. Time To Measure

Depending on which bathtub you are planning to install, it will effectively require slightly different measurements. For instance, with an undermount and a drop-in bathtub, when measuring from one end of the bathtub to the other end, you will need to extend the length and width by an inch to allow for a frame.

If you want an alcove bathtub, then measure the length of the wall and whether you will need to build a small platform to cover the extra space or if the bathtub fits in exactly between the walls.

The width is determined by measuring the furthest point of the tub to the wall.

Corner bathtubs can be a little more complicated because first, you need to make sure that the doorway is large enough to allow the bathtub to pass through and move around with ease, and then you need to start your measurements.

3. Plan for Basin Clearance

First and foremost, make sure the bathtub you are going to get will fit through the house and, more importantly, through the bathroom doors.

Once inside the bathroom, make sure you have approximately 60 inches by 30 inches of space around the bathtub in order to comfortably get in and out of the bathtub.

You will also want to make sure that you leave enough space for the cabinet doors to open all the way.

4. Know Your Depth

Soaking depth is important because it will determine whether you will get a complete soak when lying in the bathtub or just neck high. The is dependent on how tall a person is, but generally, 14 to 17 inches depth is usually sufficient to completely submerge yourself underwater.

5. Support

Bathtubs can be quite heavy depending on the material you decide to choose, not to mention the weight of the water that you will add, and then there is your weight on top. 

Make sure you check whether you will need extra floor support if you are buying a stone resin or other heavy bathtub. This is especially important if your bathroom is not on the ground floor.

FAQS Frequently Asked Questions

Here are some of the most frequently asked questions that we have been asked.

Can you fit two people in a standard tub?

The short answer is yes, and two people can fit into a standard-sized bathtub. That being said, it will, of course, depend on the size of the people. Typically it will be uncomfortable for one person once they are in the bathtub as the faucets are placed on one end, making it difficult to relax.

What is a good depth for a soaking tub?

If you are looking for a deep soak in your bathtub, then the Japanese soaking tubs are great as they are approximately 22 inches in depth, but they are not always the best option. Standard tubs are around 14 inches to 17 inches which is more than enough depth to submerge the body.

Is a 60-inch bathtub really 60 inches?

Typically the length measurement that is stated is taken from the outside of the bathtub. The inside area of the bathtub or the basin sink area is shorter. The basin sink is measured down the center base.

Bear in mind that most bathtubs are ergonomically designed to offer back support, so the bottom of the bathtub will be shorter than the top as it slants.

How long does it take to fill a bathtub?

A standard bathtub can hold anything between 45 to 60 gallons. Fill up a standard-sized bathtub with the water running at 5 to 7 gallons per minute, it will take around 10 to 15 minutes.

It can be quicker if the water pressure is good.

Do you shower before or after a bath?

Different people like doing it in their own way, but it makes sense to have a shower first and clean yourself, seeing as you will be lying in this water for a while.

That being said, you could argue that after sitting in the bathtub for a while, you want to clean yourself. we would personally suggest trying both and seeing which one you prefer.
