Love the shower niche for bottles. Our shower cubicle isn't huge (800 X 800) but feels a good size for us as there isn't some shower caddy jabbing us while we are in there.
Love the all-in-one basin and worktop - there are no joins for crud to gather in, just smooth lines. We have a large basin and a large work surface to one side, so plenty of space to have things if we want to.
Don't like the shape of our bath. It is too gently sloping at the end, which might be good for comfort but means there is a smaller floor area, so space between where bum is on bath floor and end of bath is shorter, so legs need to bend up...very disappointing when I'm a short person.
Don't like that our towel radiator is linked to just heating....so no nice dry towels in the spring/early autumn. It's okay now when it's warm and towels dry anyway, but by September when we wont have heating on, but it won't be as warm, they will be a bit damp.
Don't like water area in toilet - being Eco, it uses very little water and has just a small amount in a narrow section at borrow of toilet.....to much space further up without water for poo to stick (sorry)....means more loo brushing, which is definitely what you want in your new bathroom. Unless you see a toilet in use beforehand, I don't know how you ensure a toilet that is the shape and will fill up enough to avoid this.
Love my tiles - large metro which are flat. Mid grey grout works well.
