I have told him but have been waiting about a month now for him to come back and even look at it. Still cant use our new shower! Maybe it's time to start breathing down his neck?!

We have seen a similar issue in the past. The problem occurred when the porcelain tile on the floor did not have 100% contact with the tile adhesive, this caused water to seep down though the grout join and hold in pockets under the tile in the areas where there was no direct contact. The water being trapped in the pockets under the tile does not evaporate and can leave the tiles looking stained. If this is the case with your floor tiles the bottom row of carrara marble tiles are simply acting like a sponge drawing water up. To fix the problem we would suggest that the bottom row of carrara marble and the porcelain tiles on the shower floor need to be removed and relayed ensuring full adhesive coverage. Unfortunately this may compromise your under tile heating and waterproof membrane. Proceed with caution.

Hello Jo, You'll find that grout in any colour is nothing to be worried about. Grout Technology has come along way and permanent stains and scuffs are hardly heard of. Our suggestion is regular cleaning, using a grout sealer, and using a good quality product such as Ardex if its still a worry. From the Team at Lux Interiors.

Small bathroom and a small budget - go with a framed screen. Fixed glass, frameless panels look great, but are high end products that are expensive to make and to install. Go and do some comparison shopping and you will be surprised at the difference. You can then decide if it is worth your while spending all that extra money for that look. You will also need to carefully consider your splash distance with your open shower. Think about how much water will splash outside the shower area, and how much you like mopping the floor after every shower. So many people have been caught trying to achieve the same modern and open look in a small bathroom and now wish they had a shower door whenever they have a shower. Make sure that you have an additional floor waste outside the shower area for any overflow before the run-off reaches your door threshold. So many things to consider when renovating a small bathroom, and oversights can be expensive. Best of luck, Dr Retro of Dr Retro House Calls.
