Designing Kitchens and Bathrooms - SOLUTION NEEDED - drainage for bath surround

We have already purchased a cast-iron drop-in style tub and plumbed the shower fittings into the wall. Now we realise we could have a BIG problem with water pooling on the bath surround which sits below the bath edge and between the bath and the two corner walls. The width of the surround is only about 50mm between bath edge and wall and about 200x200mm in the corner, so we need a solution to drain away water that will definitely pool into these areas. We do not want to tile up and over the bath edge because this defeats the purpose of the drop-in bath asthetic. We do not want a shower curtain. Only solution we have so far would be to remove a portion of the tile surround and replace with an architectual lineal grate of some sort. Only types of these grates we have seen so far are stainless steel and we risk making our bathroom look more like a laboratory or surgical theatre than luxurious bathroom. Was hoping the brains trust have seen other styles of lineal grates or corner grates, maybe in ceramic instead of SS. Thank you in advance for your ideas or leads toward a solution.

So you have a drop in with deck surrounding the entire tub. You have installed a tub that was never meant to have a shower. Either install a shower curtain system that goes around the whole tub or forget about the shower. Drains arent gonna help or work here. The deck is neither sloped to a drain nor waterproofed for such. Water will pool, seep through grout lines etc and cause problems. I dont see this working at all.:thumbdn:

What if I can modify the deck so that it does fall toward a corner or if I installed a lineal drainage system between each wall and the bath? The current deck is brick and waterproofed. I could grade the final screed to a corner drain, but I haven't really seen a drain solution that doesn't look like a floor waste. I know we have stuffed up here but I need a fix that is not a shower curtain. I need a fix that is functional but discreet. How do I save the bathroom AND my marriage?

Some concepts are simply not workable, this is one of them. You have the wrong tub and there are no conventional drain fixtures for this type of alien installation.:D
