Length of walk-in shower without a door
For a walk-in shower without a door, 120 cm is usually the practical minimum. If you want less splashing, more comfort, and a warmer shower area, 140 cm is often a better choice. The right length depends not only on the available space, but also on the width of the shower, the location of the showerhead, the glass wall, and the available walking space in the bathroom.

Which size is actually comfortable in real-life use?
A doorless walk-in shower usually needs to be longer than a shower with a door. That’s because an open entrance requires more space to keep water contained within the shower area. In a small bathroom, 90 x 120 cm is often considered a practical size. For everyday comfort, a width of 90 or 100 cm and a length of about 140 cm are usually more pleasant. If you have a rain shower or want an extra open look, a length of 160 to 180 cm provides even more peace of mind and reduces the chance of wet floors outside the shower. Are you torn between a walk-in shower and a shower enclosure? Then the available length will help you make that choice.
| Situation | Approximate measurement | Practical significance |
|---|---|---|
| Small bathroom | 90 x 120 cm | Functional lower limit for smart placement of the wall and showerhead |
| Comfortable standard | 90/100 x 140 cm | More room to move and less splashing outside the shower |
| Spacious open shower | 100 x 160–180 cm | A more luxurious feel, greater comfort, and extra leeway with a wide spray pattern |
How do you prevent water splashes without a door?
In a walk-in shower without a door, the length is particularly important for containing splashing water. Therefore, it’s best not to aim the showerhead directly at the opening, but rather at the back wall or a shielded side. A fixed glass wall helps deflect the water stream before it reaches the walk-in area. The more open the entrance, the greater the chance that water will run further into the bathroom. If you find that 120 cm feels cramped, an extra 20 cm in length can make a big difference in everyday use.
Minimum Dimensions for a Small Bathroom
Even in a compact bathroom, a doorless walk-in shower can work well, as long as the proportions are right. In practice, plan for a minimum width of 90 cm and a length of 120 cm. Sometimes a smaller solution is possible, but the layout must be planned very carefully. Consider a well-placed glass partition, a showerhead that doesn’t spray toward the opening, and enough space to step in and out without getting wet. For most bathrooms, about 60 cm of clear space in front of the shower is a good guideline.
Technical factors that help determine the correct length
Drainage and Slope
The size of the shower will only work well if the water drains quickly enough. That’s why a good drain and sufficient floor slope are just as important as the length itself. A shower channel on the correct side can help keep water better contained within the shower area. Read all about drains and shower channels for walk-in showers.
Showerhead and Draft
It’s best not to install a doorless shower in the draft path of a window or vent. Otherwise, the room will feel cold more quickly. The height, angle, and width of the spray also determine how far the water reaches. With a rain shower, a longer spray is often a better choice than with a compact hand shower.
Glass wall and entryway
An entry opening of about 60 cm works well in many bathrooms. If you opt for a wider opening or a shorter glass wall, adding extra length is often the easiest way to limit water splashes without losing the open feel of the shower. Consider custom-made shower wall panels for a sleek splash guard and precise dimensions.
Frequently Asked Questions About the Dimensions of a Walk-In Shower Without a Door
How deep should a walk-in shower be without a door?
When people talk about depth, they often mean the same measurement as length. For a doorless walk-in shower, 120 cm is usually the minimum that still works practically. If you want more comfort and less splashing, 140 cm is often a better guideline.
How far do water droplets splash from a walk-in shower?
That depends on the showerhead, water pressure, and the direction of the spray. If the spray is directed toward the opening, water can end up well outside the shower area. With a good glass partition, sufficient length, and a smart layout, most of the water stays inside the shower.
What is the ideal length for a walk-in shower?
For many homes, 140 cm is a good compromise. That size combines comfort, an open feel, and a lower risk of wet floors. If you have limited space, 120 cm is often still a viable option. If you have a spacious bathroom, 160 cm or more might make sense.
What is the minimum clearance for a walk-in shower?
A shower entrance width of about 60 cm is practical in many situations. It’s also a good idea to leave enough clear space in front of the shower so you can get in and out comfortably and safely.
