ᐅ Shower tray longer than 140 cm: Can this eliminate the need for a door?

Hello everyone,

An acquaintance claims that for showers/shower trays longer than 140 cm (55 inches), you can skip the (glass) door because the water doesn’t splash that far. What are your experiences with this? Is it also financially worthwhile (cost of the glass door versus the price increase from 90 to 140 cm (35 to 55 inches), for example with steel/enamel)?

Our shower is 1.55 meters (5 feet 1 inch) long. When I shower, some water does splash out at the front, but only a little. That’s why there is a bath mat placed there.
Why do you want to use a shower tray? If you have enough space to make the shower that long, go for a walk-in shower instead.

You are probably right; having everything on one level is better. I hope this is possible with glass doors all around.

Now I want to introduce another theory. Hypothesis: It is better if the wet room is enclosed all around, because then the splashes collect and flow as a small stream down into the drain. This also results in less moisture in the room overall, and the shower dries faster afterward.

We have a 120cm (47 inch) length without a door. The first tile (30cm (12 inch)) gets wet during longer stays under the rain shower. When using the regular showerhead, everything outside remains dry.

However, we also have a 30cm (12 inch) element at the entrance area, positioned at a 90-degree angle to the long glass wall.

Some apparently shower with only 3 liters per hour! Of course, with that flow rate, even a 90 cm (35 inch) shower without walls stays dry… 😀

Bottom line: 1.50 m (5 feet) without a door is not enough; 1.80 m (6 feet) is.

The orientation of the faucet affects the splashing.
If there is a width of 1m+ (3.3 feet) or more, the shower can also splash sideways.
Our shower, which is a niche between the wall/wall/sauna wall and open to the front, is 1.4m (4.6 feet) wide. This results in minimal splashing outside, and we don’t have any glass to clean.
