Had both our bathrooms installed by them. I can only count the list of problems:-
1) one of the units was delivered with a crack in it - we got this exchanged
2) both toilets' seats broke after 6 months and we had to purchase new ones
3) after 2 years, one of the Corian basin has a crack on the bowl so waste water is leaking through
NOT IMPRESSED especially for the amount of money they charge.
After sale service poor.
