If you do opt for a glass fire rated door the below fire rated door is the most minimal I have ever come across. No frame, the only profile is an 18mm back painted band around the perimeter of the glass door to protect the fire rated intumescent seal and can be made to a fire rating of up to 60/60. Frameless Fire Rated Doors We have one of these doors on show at our showroom in Amersham. Let me know if you want any other information or if you want to arrange a visit to the showroom.

@ Pookes - this is a common situation where the external corners are often forgotten. Have you gone back to your tiling supplier to see if the tiles that you bought have a ceramic/porcelain corner section available? if so, and depending on the dimensions, you may be able to give yourself the minimalist look that you are looking for. Unfortunately your first photograph, showing the aluminium trim, is typical of the covering up of a design detail that has been forgotten. This maybe your only option although there are colour alternatives available that might make it easier to live with.

I think we actually have a larger gap than you do! Definitely get sound leakage, however tbh we don't shut them that often. We have a brush edging between the frame and the doors on both sides, but not between the doors themselves. I think the issue would be attaching it now that the doors are in (unless you can take the doors off easily still. as it'd either need to be at the front edge of the door that stays nearest the walls, or the back of the one that meet in the middle. Definitely worth trying to add if you're able to. other thing to consider if sound insulation is very important, we had the handles.. we had the finger pulls that sit on the ends of the doors? but i'm not entirely sure if it's just how they were inserted, but they dont sit 100% flush, meaning when shut there's a slight gap in the middle as well. We said about trying to change it, to get them more flush, but they'd have essentially damaged the doors trying to pry them out by that point! 🤦🏻‍♀️
