A Beginner Guide: Understanding Standard Shower Sizes

According to the International Residential Code, the smallest sized shower stall is 30 inches x 30 inches. As you’ll see below, most showers are larger than this.

Keep in mind that these measurements are for the inside of the shower stall, so you will need to add a few inches to each for the door.

Most shower stalls are between 32 and 36 inches wide, although it’s not unheard of for this to vary. The depth is typically at least 60 inches, but you can go up to 72 if you don’t mind a really tight shower.

To comply with the ADA accessibility standards, your standard shower stall must be at least 36 x 36 inches – this should give you an idea of what your limitations are.

2. What if my bathroom is smaller?

This makes it easy to install a basic shower in any bathroom, regardless of size.

3. Do I need a curbless shower?

curbless showerA curbless shower is one where the threshold is level with the rest of the floor. 

This eliminates the possibility of a dangerous tripping hazard and makes it much easier to wheelchair or walk in. If your bathroom is not accessible, you may want to look for a shower kit with a curbless threshold.

If you do not have this type of bathroom, don’t worry – as long as there is enough room to install a threshold (typically about 2 inches), you can have any type of shower.

4. What kind of shower should I choose?

Once you have determined the size of your shower stall, it’s time to decide what type of shower is best for your bathroom. You can choose between a pre-fabricated shower, a custom tile shower, or a frameless glass shower.

4.1 Pre-fabricated showers

This is the most common type of shower, although it is the least customizable.

4.2 Custom shower tiles

This is a more expensive option, but you will get the shower of your dreams.

4.3 Frameless glass showers

The main downside to this type of shower is the high price tag.


Whichever type of shower you choose, make sure to consult with a professional to ensure that it is installed correctly. This is especially important for frameless glass showers, which can be very dangerous if not installed properly.

Lastly, if you have more space to work with, then creating a walk-in shower might be a good option. This can be done with any type of shower, and will allow for more flexibility in terms of your size you are going for. Just keep in mind that the bigger you go, the more you will have to consider proper ventilation.

Finally, bathroom size will always be a factor and will ultimately guide the type and design of the shower you end up installing. Sometimes, less is better…. Goodluck!
