We got the IKEA shelves that are pictured in the butlers pantry photo I posted when we were on holiday in Melbourne, Australia. We don't have IKEA here in New Zealand! Hubby is going back over in May/June so will get him to get more of that sort of thing when there. We would pay about 4x the price for that sort of thing here in NZ. I need to work out what I will do now where the fridge was and there is the angle change (does that make sense?).

You could do a wet room on the south end of the room with the tub and shower combined to conserve space. Window would go above tub, however with privacy in mind it would not be low as you have in your cad drawing. see photo. Vanities would go on the west wall with toilet on the east wall. I am guessing at the dimensions because you mention meters and in the US we use feet, but it sounds like about 9'x15" ? The location of the entry door really impacts the layout of the room, but it looks like it cannot be moved.

Normally a hot tub comes with a means of heating the water, and maintaining it without having to empty the water. This is where water filtration and disinfection methods are worth it and less wasteful. It really doesn't matter whether it is stainless steel or not: you are heating up water to levels that naturally promote bacteria and algae. Hence the NEED for some type of disinfection - which can range from tossing in a chlorine table to add ozone or other types. I suggest you purchase a book entitled "What colour is Your Swimming Pool" 2003 edition. It will give you a practical guide to what you are looking for to maintain your spa tub and why you need to do it.

Thanks very much for all your feedback. Just to answer a few queries - the deck is directly outside the main room so the new doors open out onto it. The doors won't be French - they're just the only doors that the 3D planner I'm using had, they'll actually be large stacking doors. I've had another idea too which would be a lot more expensive but offers a completely different approach. This is quite rushed so doesn't show accurate layout of kitchen or anything like that, basically just provides an idea. Thoughts!?
