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

Exactly, that’s why originally it was the 66 x 114 (millimeters) (about 2 5/8 x 4 1/2 inches) – so two of those. But since that’s no longer possible – only the 55 x 78 (millimeters) (about 2 1/8 x 3 inches) from Lux are available – the options now would be either two 74 x 78 (millimeters) (about 2 7/8 x 3 inches) windows from Oto or one 134 x 78 (millimeters) (about 5 1/4 x 3 inches) window from Oto (which would then be placed over the rafters).
