ᐅ Options for Roof Windows

Hello everyone,

We have a bathroom on the upper floor with an area of about 8 m² (86 sq ft). Originally, we planned (in coordination with both the planner and the carpenter) to install two roof windows measuring 78 x 114 cm (31 x 45 inches) (W x H).

However, the roofer now says that due to the battening, neither the 114 cm nor the 98 cm height will work, and only windows sized 55 x 78 cm (22 x 31 inches) are possible (don’t ask me what went wrong here – I assume the detailed planning could have been more thorough). Well, that’s how it is now.

We are concerned that it might be too dark. Apparently, wider windows—something like 140 x 78 cm (55 x 31 inches)—are not available. As an alternative, a daylight spot was recommended to us, but we’re not very convinced by this, as it would require some ductwork on the attic floor and would probably increase the cost.

I find it hard to imagine the size – will two smaller windows (55 x 78 cm) be sufficient to provide comfortable natural light in the bathroom with a 45° roof pitch?

Do you know of any other solutions—for example, manufacturers that offer windows in different formats? The roofer is apparently using brands like Lux or Oto.

Thanks for your input.
Best regards

The large window plus a beam will probably not differ much in cost compared to the two smaller windows.

Just to throw in an unqualified opinion (we are currently planning too):
with a knee wall height of 1.60 meters (5 feet 3 inches), I would NOT install a roof window at all but rather save that money and put a relatively narrow window across the entire width of the wall (or two, depending on the price). Of course, the sink and toilet would then need to be swapped so you don’t end up sitting in public view...

With a knee wall height of 1.60 meters (5 feet 3 inches), it is generally quite difficult to reach the window or the window handle—unless you are very tall.

We had thought the same (then it would have been automatic) – but now we have discovered a model where the handle is at the bottom... which of course is inconvenient when closing. Let’s see – maybe it will be electric.

Is there anything else? I don’t remember the floor plan anymore... 😳
