It would be preferable to add white tinter of the same compatible brand/type/etc. of paint as it could react with it if not compatible. A local paint place could supply a small amount of white to tint it yourself or have them do it for you.

That is gorgeous - nice transformation! Great use of the space you had available to work with :)

We installed a skylight over shower (velux fixed) in a tiny ensuite and I would highly recommend. It looked absolutely amazing and was heavenly to shower under the sky. We only had the house for a year and sold it (about to install another skylight over shower in our new house), so I can't comment on the long term, but no mould problems or condensation drips. I think if anything the sunlight was actually helpful to dry up moisture. We live in Tasmania so I'd doubt condensation dripping would be a problem elsewhere. We had a fan installed not in the cavity with the skylight but just on the ceiling next to it. In the second bathroom we put in a skylight over bath and put an extractor in the skylight cavity as the ceiling was higher. Could not feel a draught- so I think the question of where to put fan really depends on ceiling height. Do the skylight over shower!! You will not regret it. It really takes your bathroom to another level and there are really no maintenance problems if installed properly with custom flashings. I found velux quite repellent of dirt etc, we did not need to clean after a year (one flat roof skylight, one very large sloped) and I have seen velux skylights looking great with no cleaning for 7 years plus.

Amazing transformation! It has a real peaceful and relaxing vibe! love it!
