I love three in ones because if one bulb explodes, you've usually got a fair few backups before you have to completely fix the bulb (but that's just the laziness in me coming out). In my opinion, I don't think you need a demisting mirror because that's what the fan is for in the three in one.

Thankyou very much!

Ideas for lighting in an open plan kitchen/lounge plus bathroom and ensuite

Hi Emily, This does seem quite extreme for such a small renovation. I recommend that you investigate getting a CCTV inspection done. They will put a camera down the closest manhole and follow the pipe along. Make sure if you do this, you ask the CCTV drain inspectors to locate the drain for you and place pegs on site. You may be able to find a solution from there. Second option is to re-look at the floor plan to establish if there is a better place to relocate the toilet without needing another gully trap. 2.5 bathrooms is quite generous so for resell it may not be necessary, although there may be other alterations you could do to improve circulation, flow and functionality. Good luck with your renovations.
