An all weather outdoor shower is easily done by locating the mixing valve inside the house and use a coupling shaft to locate the handle on the outside. You must use a standard tub type lower faucet (with the pull up to activate the shower) to allow the system to drain out when the shower is done. You also have to make sure everything slopes in direction of the water flow. We live in Bancroft Ontario so winters are well below freezing and we have been showering outside for 3 winters. Only issue we have is the shower head will freeze so we typically remove it after a shower or shower without it on when really cold. The system has worked well and it helps that nothing special needs to be done by anyone. no inside valves to close etc. Just turn off tap and everything drains.

Excuse my duh-ness but i'm having difficulty trying to follow whats going on here. Are these two photos an exact replica of your house and pool ? If not a hasty sketch with dimensions could help a lot. By kitchen wall do you mean the wall behind the bar ? And where is the pool wall ? Are you considering the covered area as being "inside" ? Sorry for all those questions lol Sometimes when you have a design problem you need to turn it inside out or on it's head. If you can't beat it maybe embrace it by making a feature of it : i.e. contrast by having the lightest colored pool surround and a great blue or tile inside and under the overhang, something that will echo the water color ? If you have a great covered area as in photo you'll most likely be spending a lot of time there and it could be soothing to be able to sometimes retire into a darker inside. In my book, 10M isn't small and also contrasting two floor colors doesn't necessarily make a space seem smaller and confined and may in fact even open it up. Could it be that you've thought yourself into a box here ? Sometimes one needs to give it all a good shake up and see how it resettles.

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.

It all depends on what you want to do in your laundry and what in your bathroom I guess. I appreciate the fact that there might not be enough space to do this but I store outdoor shoes in the laundry and the dog's leash and cleaning stuff. I need room to sort the dirty laundry into piles before washing it. I keep the ironing board in there and I need a tub to wash things in and to do flowers in and to put the odd cloth that wiped up the cat sick before it gets rinsed and washed.. heaps of things other than just washing. Couldn't manage with a cupboard laundry ( piles of washing on the hall floor when using it) and think these kinds of laundry functions might not make a gorgeous lavendery bath or shower feel that luxurious. So I am for as big a laundry with tubs, cupboard and bench nearest the outside back entrance and yes washing line as poss. And a lovely fresh warm bathroom near the bedroom separate from the dirty clothes and boots and all that other stuff.
