We have incredibly hard water, no softener and lots of mineral deposits on everything that touches water for any length of time. The solution is incredibly simple: white vinegar. It very simply and easily and gently dissolves the minerals. We had a shower head that my husband was ready to replace because the mineral deposits had clogged it. I unscrewed the head, submerged it in a cup of vinegar for 24 hours, rinsed it off and screwed it back on. Voila! Like new! I have tried CLR: worthless. I have tried abrasives: all they do is scratch and don't get rid of the deposits. Another spot where minerals accumulate is around the kitchen faucet. I take a bunch of paper towels, soak them in vinegar, then pack them around the faucet over the mineral deposits, keeping them good and wet with vinegar and let them sit for about a day, more or less. Rinse and wipe clean, will look like new! Our cat loves water. His favorite thing in the world is if I fill the bathroom sink with water and let him play in it. What happens? Water spots all over the mirror. Wet a cloth, add a dash of vinegar to the cloth, wipe the mirror... clean and shiny!

I like this tile as well. Very sleek and mod looking. I would consider running it vertically instead of the picture horizontal pattern. It might give the illusion of more height in the shower surround. The color is great. If you are worried about it being "too much," you could always see if they have the same tile in a different shade and mix the two or doing one wall in a contrasting (lighter) color. I personally like it as long as you have good lighting.

Sorry but I don't understand your pictures. You are talking about 2 bathrooms but we see only one floor plan. Is the 1.52M x 2.24M the 5 x 8 bathroom in your dilemma title. If so, can we see the floor plan of the 5 x 9 bathroom? Is the space with a small rectangle in the middle the extra 5.5 x 4.9 ft space you mentioned in your dilemma? Also 1.52M x 2.24M is in reality 5'0" x 7'4". This is 8 in. less. It can make a big difference on how to place fixtures in a bathroom.

Also, I would like more counter space. What size of the sinks should I get? 18 inch? Thank you.
