Base to back and front wall transition
The base to back and front wall transition should also be
considered. The back wall should be as close to 90°, and
at as sharp a radius as possible (Fig.8). Curved geometry
is more likely to increase splashback, whereas sloping back
and front wall transitions should be avoided (Fig.9 & 10).
Water drainage
Due to high velocity air and water being in close proximity,
there is a chance of some water and soap dispersion outside
the sink dimensions. To alleviate this effect, we recommend
following the below guidelines.
Base Profile
Flat base profile will result in poor drainage leading
to high levels of splashback.
To improve drainage, avoid sinks with a flat base with particular
focus on the immediate area surrounding the drain hole,
minimum 2

" radius (Fig.7).
Vertical and sharp transition
Vertical and smooth transition
Sloped transition
Minimum of 6° ramp angle from the edge of the drain hole
of the sink will result in good drainage leading to reduced
levels of splashback (minimum 2

/
8
" radius).
