Impressive. Far too modern in style for us, but that doesn't matter :-)

How's it sealed round the edges, e.g. floor-to-wall? And I assume the
underfloor pipes are not insulated, right? Does anyone insulate underfloor
pipes? We've got some longish pipe runs to a downstairs loo, and it takes
an age to get hot water through. Waste of water and energy, but I wondered
what the standard is.

The floor is a wedi fundo tray http://www.wedi.co.uk/fundokits.php: 40mm
"Styrofoam core coated with a polymer-modified cement coating and
reinforced with glass fibre". The walls are similar but 12mm. All the
joints were taped with a rubberised sealing strip before tiling. And just
in case there is some silicone on the corners. It's been very satisfactory
for five years now. The 40mm of insulation underfoot means the tiles never
feel cold.

As its in a 2nd floor flat uninsulated pipes are not too much of a worry.
If I was doing it again I might do so, but the problem of having to wait
for hot water to come through is down to the combi boiler. Insulation might
make some difference if the water system was in constant use, but I am out
all day, and it is usual for several hours to pass before hot water is
needed again.
