This blog takes a look at progress with the wet units. Wet units are compartments where the whole floor is, in effect, one large shower tray. If you have been on a cross channel ferry or a cruise ship then the chances are the toilet compartment was a wet unit. Any water spilt or overun from the shower outside the curtain will flow to a drain in the corner. In addition to the shower, the unit contains a toilet, washbasin and cupboard etc. The toilet is not like the one you have at home but is like the one on a ferry. Press the button and everything disappears by vacuum. 
This means some plumbing and controls that look a bit complicated. That is the price to pay for the system which is aimed to be very much better than a gravity system to holding tanks. In fact the vacuum system has made possible the e-suite facility in every cabin. Without the vacuum system, we would have stayed with the original design - central washrooms/toilets/showers with only a washbasin in each cabin.
There is more progress today to report and hopefully this will be posted on Thursday evening.
