It depends on many things, but also are within these guidelines. A splash back provides a surface which is to be impervious to water, therefore not allow water to absorb, and depending on your state, the regulations directly behind a water point including a tap or outlet is to be minimum 200mm high, and for heat and fire ratings, the area behind a cooktop needs to be 600mm minimum from your bench top is you have an electric cooktop, and 650mm for gas, with the splash back to extend 200mm either side of the heat source either side. So even if you want to only do this, there will need to be quite a bit of splash back, and often people use things like the bench top, window position and overhead cupboards to contain the splash back, providing you a rough idea of where to start and end one. Although not technically required, even in areas without services, a splash back that changes height and doesn't continue around walls to neatly finish off the surface will look out of place, so for consistency, the splash back is best used to effect, and provides an opportunity to incorporate a colour or interesting surface to the kitchen. By no means should a splash back be an after thought or put in simply in response to the minimum regulations. If you have a layout of your kitchen, start where your overhead cupboards are and draw a line around the entire room (even through windows and openings) to see it complete each wall that is part of the kitchen. Meaning any wall that has a bench top attached. Tis is a good place to start. Hope this helps.

I agree! Go for what you love. Down the track at resale time, if you feel it's too dated then, there are many splash back materials that can be applied right over top of tile. Is it just the area behind the cook top that will be tiled? I think anything will feel like "too much" at first if you've become accustomed to how it currently is. It's like when you paint a room. It can feel overwhelming at first until you begin to put furniture and decor back in place. A simple way to trial colours is to tack up some wrapping paper, fabric, contact paper (backing left on) or whatever you find that has a colour you think could work. Try use things with different sheen/gloss. Even paint a board and prop it there. Leave for a few hours and see what does and doesn't work for you.

Hi kristymacd, after changing my mind many times we went for a built in 1700 bath! Mostly as builder and tiler thought it would be easier to slope the floor properly and I liked the idea of the slightly larger built in compared to the 1590 back to wall. I’m sure a back to wall would’ve been possible and been fine, it all just got a bit hard and I knew both would look good. And I don’t think a back to wall would be any harder to clean than a built in - with a built in you have the hob and tiled face of the bath and back to wall there is the floor either side of the bath - same same! Here’s a pic of ours, not totally finished yet but really happy with it.
