@suancol, You are alone at present but what if that changes and you hook up with a chef for example??.....who will cook your home into oblivian ha-ha In my opinion, if you cook in your kitchen even a little, if you don't have a foolproof extraction system, then all the steam etc... even laden with perhaps minimal fat but cooking particles non the less, will eventually see you plastering the entire open plan living with a serious mess. I'm not having overheads as such either for height reasons, I'm very short and overheads serve no purpose for me personally but I wouldn't dream of not having a rangehood, so I will still have two cupboards, one on either side to simply balance the rangehood, so you can have both without covering your entire uper wall area with wall to wall cupboards. I strongly suggest you search Houzz photo's for rangehoods in kitchens and see if you can find a design and rangehood you might be able to live with, as I certainly wouldn't be paying the sort of price suggested for a Gagenau system nor do I think you will ever be happy with an after market wall fan, I think it will look cheap. Good luck with your search.

are you after a exhaust fan only or a exhaust,light and heat? you basically need to look at the m3 / hour, 555/M3 is at high end and below 255/m3 is at the low end. You don't need to spend a lot of money to get a good exhaust fan they are quite but if you want no noise try an online fan this will be away from the fan opening. There is a lot of option so pick one you like the look of but make sure the m3/hour is good and position of the exhaust helps a lot try and have it over the shower area this will help with steam escape quicker.

Direct downlights over your vanity basin will cast dark shadows down your face and make you look ten years older. You are better off with softer lights either side of the mirror at eye height. If you don't believe me then grab a hand mirror and look at your face when standing under a spotlight. Save your money and buy the cheaper 3 in one heat lamp. Don't bother with the downlights over the basin - even though your electrician will tell you that is how he always installs them. Spend what you have saved on good wall lights, then you can thank me for making you look ten years younger due to better lighting and better make-up. Best of luck Dr Retro of Dr Retro House Calls

Hi Julia, I have drawn up as per your description. The shower recess could be no bigger than 1000x1000, as you need an area to access toilet, cupboard and for drying off. With this size shower you could have a shower curtain, therefore not worrying about the swing area required for shower door. If you want a door, then I suggest the shower recess needs to be reduced to 1000x900mm. Then you would just have enough room to swing door, but not all the way. Either way, even with a 900x900 shower and a door, it is tight. Waste for shower to be centred in the shower recess, with correct fall installed by tiler.
