I have a window by my shower and currently the window sill gets very wet when I have a shower. The window sill is slightly bowed, so that the lowest point is along the centre line of it, between the window and the edge of the sill. So inevitably this means that water pools on it, and over time the paint on the sill ends up cracking and the underlying wood starts to show. This is obviously no good, and I've decided to tile the window sill (with mosaic tiles).
But I'm wondering whether tiling will be enough to solve the problem. When I tile the sill this centre line will still be the lowest point, and water will continue to collect there. It won't be so bad that that happens on tiles rather than on wood, but still it would be better if I could prevent it. So should I try to build up this part of the window sill before tiling, so as to create a slope away from the window? And if so, how? I reckon it needs to be raised by about 3mm at most to achieve this.
Grateful for any help.
